Efficient Method for Liposome-Based Gene Transfer in Cattle Embryos.

In vitro embryo production (IVP) in cattle is crucial for advancing genetic enhancement and preserving valuable genetic lineages, enabling precise genetic modifications and gene studies through modern techniques. Successful genetic manipulation in cattle embryos requires efficient delivery of exogenous DNA/RNA molecules. This research investigates the efficacy of a single embryo culture system for developing genetically modified zona-free (ZF) embryos and examines the use of liposome-based SAMTOR target siRNA transfer in these individually cultured ZF embryos. The findings indicated that the individual culture system resulted in increased cleavage rates, and blastocyst rates were minimally impacted. The new culture system effectively achieved SAMTOR silencing, with 8-16 cell embryos exhibiting reduction in transcript levels compared to control. Measurement of total protein content in the spent culture media was performed to validate the single-culture approach for further analytical applications. Total protein content analysis demonstrated the system's suitability for comprehensive evaluation of the embryo-media interaction, enhancing the scope for in-depth genetic research and applications. This research sheds light into an innovative method to improve genetic editing techniques in reproduction research.

Optimized lipid nanoparticles enable effective CRISPR/Cas9-mediated gene editing in dendritic cells for enhanced immunotherapy

Immunotherapy has emerged as a revolutionary approach to treat immune-related diseases. Dendritic cells (DCs) play a pivotal role in orchestrating immune responses, making them an attractive target for immunotherapeutic interventions. Modulation of gene expression in DCs using genome editing techniques, such as the CRISPR-Cas system, is important for regulating DC functions. However, the precise delivery of CRISPR-based therapies to DCs has posed a significant challenge. While lipid nanoparticles (LNPs) have been extensively studied for gene editing in tumor cells, their potential application in DCs has remained relatively unexplored. This study investigates the important role of cholesterol in regulating the efficiency of BAMEA-O16B lipid-assisted nanoparticles (BLANs) as carriers of CRISPR/Cas9 for gene editing in DCs. Remarkably, BLANs with low cholesterol density exhibit exceptional mRNA uptake, improved endosomal escape, and efficient single-guide RNA release capabilities. Administration of BLANmCas9/gPD-L1 results in substantial PD-L1 gene knockout in conventional dendritic cells (cDCs), accompanied by heightened cDC1 activation, T cell stimulation, and significant suppression of tumor growth. The study underscores the pivotal role of cholesterol density within LNPs, revealing potent influence on gene editing efficacy within DCs. This strategy holds immense promise for the field of cancer immunotherapy, offering a novel avenue for treating immune-related diseases.

New CRISPR/Cas9-based Fgfr2C361Y/+ mouse model of Crouzon syndrome exhibits skull and behavioral abnormalities.

Crouzon syndrome (CS), a syndromic craniosynostosis, is a craniofacial developmental deformity caused by mutations in fibroblast growth factor receptor 2 (FGFR2). Previous CS mouse models constructed using traditional gene editing techniques faced issues such as low targeting efficiency, extended lineage cycles, and inconsistent and unstable phenotypes. In this study, a CRISPR/Cas9-mediated strategy was employed to induce a functional augmentation of the Fgfr2 point mutation in mice. Various techniques, including bone staining, micro-CT, histological methods, and behavioral experiments, were employed to systematically examine and corroborate phenotypic disparities between mutant mice (Fgfr2C361Y/+) and their wild-type littermates. Confirmed via PCR-Sanger sequencing, we successfully induced the p.Cys361Tyr missense mutation in the Fgfr2 IIIc isoform of the extracellular domain (corresponding to the p.Cys342Tyr mutation in humans) based on Fgfr2-215 transcript (ENSMUST00000122054.8). Fgfr2C361Y/+ mice exhibited characteristics consistent with the phenotypic features associated with CS, including skull-vault craniosynostosis, skull deformity, shallow orbits accompanied by exophthalmos, midface hypoplasia with malocclusion, and shortened skull base, notably without any apparent limb defects. Furthermore, mutant mice displayed behavioral abnormalities encompassing deficits in learning and memory, social interaction, and motor dysfunction, without anxiety-related disorders. Histopathological examination of the hippocampal region revealed structural abnormalities, suggesting possible brain development impairment secondary to craniosynostosis. In conclusion, we constructed a novel gene-edited Fgfr2C361Y/+ mice strain based on CRISPR/Cas9, which displayed skull and behavioral abnormalities, serving as a new model for studying genetic molecular mechanisms and exploring treatments for CS. KEY MESSAGES: CRISPR/Cas9 crafted a Crouzon model by enhancing Fgfr2-C361Y in mice. Fgfr2C361Y/+ mice replicate CS phenotypes-craniosynostosis and midface anomalies. Mutant mice show diverse behavioral abnormalities, impacting learning and memory. Fgfr2C361Y/+ mice offer a novel model for cranial suture studies and therapeutic exploration.

Agriculture plays a fundamental role in ensuring global food security, yet plant diseases remain a significant threat to crop production. Traditional methods to manage plant diseases have been extensively used, but they face significant drawbacks, such as environmental pollution, health risks and pathogen resistance. Similarly, biopesticides are eco-friendly, but are limited by their specificity and stability issues. This has led to the exploration of novel biotechnological approaches, such as the development of synthetic proteins, which aim to mitigate these drawbacks by offering more targeted and sustainable solutions. Similarly, recent advances in genome editing techniques—such as meganucleases (MegNs), zinc finger nucleases (ZFNs), transcription activator-like effector nucleases (TALENs) and clustered regularly interspaced short palindromic repeats (CRISPR)—are precise approaches in disease management, but are limited by technical challenges and regulatory concerns. In this realm, nanotechnology has emerged as a promising frontier that offers novel solutions for plant disease management. This review examines the role of nanoparticles (NPs), including organic NPs, inorganic NPs, polymeric NPs and carbon NPs, in enhancing disease resistance and improving pesticide delivery, and gives an overview of the current state of nanotechnology in managing plant diseases, including its advantages, practical applications and obstacles that must be overcome to fully harness its potential. By understanding these aspects, we can better appreciate the transformative impact of nanotechnology on modern agriculture and can develop sustainable and effective strategies to mitigate plant diseases, ensuring enhanced agricultural productivity.

Cell-Penetrating Peptides and CRISPR-Cas9: A Combined Strategy for Human Genetic Disease Therapy.

The advent of Clustered regularly interspaced short palindromic repeats (CRISPR)-CRISPR-associated nuclease 9 (Cas9) technology has revolutionized the field of genetic engineering, offering unprecedented potential for the targeted manipulation of DNA sequences. Advances in the mechanism of action of the CRISPR-Cas9 system allowed potential applicability for the treatment of genetic diseases. CRISPR-Cas9's mechanism of action involves the use of an RNA guide molecule to target specific DNA sequences and the Cas9 enzyme to induce precise DNA cleavage. In the context of the CRISPR-Cas9 system, this review covers non-viral delivery methods for gene editing based on peptide internalization. Here we describe critical areas of discussion such as immunogenicity, emphasizing the importance of safety, efficiency, and cost-effectiveness, particularly in the context of treating single-mutation genetic diseases using advanced editing techniques genetics as prime editor and base editor. The text discusses the versatility of Cell-Penetrating Peptides (CPPs) in forming complexes for delivering biomolecules, particularly Ribonucleoprotein (RNP) for genome editing with CRISPR-Cas9 in human cells. In addition, it emphasizes the promise of combining CPPs with DNA base editing and prime editing systems. These systems, known for their simplicity and precision, hold great potential for correcting point mutations in human genetic diseases. In summary, the text provides a clear overview of the advantages of using CPPs for genome editing with CRISPR-Cas9, particularly in conjunction with advanced editing systems, highlighting their potential impact on clinical applications in the treatment of single-mutation genetic diseases.

Multifunctional vitamin D-incorporated PLGA scaffold with BMP/VEGF-overexpressed tonsil-derived MSC via CRISPR/Cas9 for bone tissue regeneration

Guiding endogenous regeneration of bone defects using biomaterials and regenerative medicine is considered an optimal strategy. One of the effective therapeutic approaches involves using transgene-expressed stem cells to treat tissue destruction and replace damaged parts. Among the various gene editing techniques for cells, clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein 9 (Cas9) is considered as a promising method owing to the increasing therapeutic potential of cells by targeting specific sites. Herein, a vitamin D-incorporated poly(lactic-co-glycolic acid) (PLGA) scaffold with bone morphogenetic protein 2 (BMP2)/vascular endothelial growth factor (VEGF)-overexpressed tonsil-derived MSCs (ToMSCs) via CRISPR/Cas9 was introduced for bone tissue regeneration. The optimized seeding ratio of engineered ToMSCs on the scaffold demonstrated favorable immunomodulatory function, angiogenesis, and osteogenic activity in vitro. The multifunctional scaffold could potentially support stem cell in vivo and induce the transition from M1 to M2 macrophage with magnesium hydroxide and vitamin D. This study highlights the improved synergistic effect of a vitamin D-incorporated PLGA scaffold and a gene-edited ToMSCs for bone tissue engineering and regenerative medicine.

CRISPR-prime editing, a versatile genetic tool to create specific mutations with a single nucleotide resolution in Leptospira.

Leptospirosis, caused by pathogenic bacteria from the genus Leptospira, is a global zoonosis responsible for more than one million human cases and 60,000 deaths annually. The disease also affects many domestic animal species. Historically, genetic manipulation of Leptospira has been difficult to perform, resulting in limited knowledge on pathogenic mechanisms of disease and the identification of virulence factors. The application of CRISPR/Cas9 and its variations have helped fill these gaps but the generation of knockout mutants remains challenging because double-strand breaks (DSBs) inflicted by Cas9 nuclease are lethal to Leptospira cells. The novel CRISPR prime editing (PE) strategy is the first precise genome-editing technology that allows deletions, insertions, and base substitutions without introducing DSBs. This revolutionary technique utilizes a nickase Cas9 that cleaves a single strand of DNA, coupled with an engineered reverse transcriptase and a modified single-guide RNA (termed prime editing guide RNA) containing an extended 3' end with the desired edits. We demonstrate the application of CRISPR-PE in both saprophytic and pathogenic Leptospira from multiple species and serovars by introducing deletions or insertions into target DNA with a remarkable precision of just one nucleotide. Additionally, we demonstrate the ability to genetically manipulate Leptospira borgpetersenii, a prevalent pathogenic species of humans, domestic cattle, and wildlife animals. Rapid plasmid loss by mutated strains in liquid culture allows for the generation of knockout strains without selective markers, which can be readily used to elucidate virulence factors and develop optimized bacterin and/or live vaccines against leptospirosis.IMPORTANCELeptospirosis is a geographically widespread bacterial zoonosis. Genetic manipulation of pathogenic Leptospira spp. has been laborious and difficult to perform, limiting our ability to understand how leptospires cause disease. The application of the CRISPR/Cas9 system to Leptospira enhanced our ability to generate knockdown and knockout mutants; however, the latter remains challenging. Here, we demonstrate the application of the CRISPR prime editing technique in Leptospira, allowing the generation of knockout mutants in several pathogenic species, with mutations comprising just a single nucleotide resolution. Notably, we generated a mutant in the Leptospira borgpetersenii background, a prevalent pathogenic species of humans and cattle. Our application of this method opens new avenues for studying pathogenic mechanisms of Leptospira and the identification of virulence factors across multiple species. These methods can also be used to facilitate the generation of marker-less knockout strains for updated and improved bacterin and/or live vaccines.

Bridging the Knowledge Gap: Utilization of Mediator Subunits for Crop Improvement.

The Mediator complex is a multisubunit transcription coregulator that transfers regulatory signals from different transcription factors to RNA polymerase II (Pol II) to control Pol II-dependent transcription in eukaryotes. Studies on Arabidopsis Mediator subunits have revealed their unique or overlapping functions in various aspects of plant growth, stress adaptation and metabolite homeostasis. Therefore, the utilization of the plant Mediator complex for crop improvement has been of great interest. Advances in genome editing and sequencing techniques have expedited the characterization of Mediator subunits in economically important crops such as tomato, rice, wheat, soybean, sugarcane, pea, chickpea, rapeseed and hop. In this review, we summarize recent progress in understanding the molecular mechanisms of how the Mediator complex regulates crop growth, development and adaptation to environmental stress. We also discuss the conserved and diverse functions of the Mediator complex in different plant species. In addition, we propose several future research directions to deepen our understanding of the important roles of Mediator subunits and their interacting proteins, which would provide promising targets for genetic modification to develop new cultivars with desirable agronomic traits.

The Image of the US Army in American movies: The Soft Power of American Cinema

The formation of the army's image has acquired newfound significance in our time. Paradoxically, alongside the spread of humanist ideology, the number of violent conflicts worldwide is increasing. These stimulates the need for propaganda aimed at shaping the image of the army and enhancing the attractiveness of service. As one of the world's largest military forces, the US army has engaged in a diverse array of conflicts with over 750 military bases in approximately 80 countries (Kohli 2020). A diverse range of tools is employed to shape the image of the US army, including media, recruitment campaigns, social media, public events, etc. Among these tools, movies have their specific role. While traditionally intended for entertainment, movies have been used for over a century as a means to shape public opinion. This article delves into the main attributes of the US Army as a social institution, analyzing its four fundamental characteristics: the Militia Tradition, Mobilization Miracles, Man-Mindedness, Maritime Influence, the weapon and the enemy as distinctive attributes. Additionally, it features the seven core values of the US Army: Loyalty, Duty, Respect, Selfless Service, Honor, Integrity, and Personal Courage. The article provides a detailed analysis of how various components of movie production tools communicate the attributes and core values of the US Army and contribute to shaping its image, examining a high-viewership movie “Interceptor” (2022). The goal of the study was to find out the image of the US Army that “Interceptor” projects and to identify the verbal and visual communicative means it uses for this purpose. The content analysis made it possible to distinguish verbal and visual elements of the movie, encompassing human voice, mise-en-scène, as well as film editing techniques, to identify and highlight the messages and ideas conveyed about the attributes of the US Army.

Revolutionizing soybean genomics: How CRISPR and advanced sequencing are unlocking new potential.

Soybean Glycine max L., paleopolyploid genome, poses challenges to its genetic improvement. However, the development of reference genome assemblies and genome sequencing has completely changed the field of soybean genomics, allowing for more accurate and successful breeding techniques as well as research. During the single-cell revolution, one of the most advanced sequencing tools for examining the transcriptome landscape is single-cell RNA sequencing (scRNA-seq). Comprehensive resources for genetic improvement of soybeans may be found in the SoyBase and other genomics databases. CRISPR-Cas9 genome editing technology provides promising prospects for precise genetic modifications in soybean. This method has enhanced several soybean traits, including as yield, nutritional value, and resistance to both biotic and abiotic stresses. With base editing techniques that allow for precise DNA modifications, the use of CRISPR-Cas9 is further increased. With the availability of the reference genome for soybeans and the following assembly of wild and cultivated soybeans, significant chromosomal rearrangements and gene duplication events have been identified, offering new perspectives on the complex genomic structure of soybeans. Furthermore, major single nucleotide polymorphisms (SNPs) linked to stachyose and sucrose content have been found through genome-wide association studies (GWAS), providing important tools for enhancing soybean carbohydrate profiles. In order to open up new avenues for soybean genetic improvement, future research approaches include investigating transcriptional divergence processes, enhancing genetic resources, and incorporating CRISPR-Cas9 technologies.

Two decades of progress in glioma methylation research: the rise of temozolomide resistance and immunotherapy insights.

This study aims to systematically analyze the global trends in glioma methylation research using bibliometric methodologies. We focus on identifying the scholarly trajectory and key research interests, and we utilize these insights to predict future research directions within the epigenetic context of glioma. We performed a comprehensive literature search of the Web of Science Core Collection (WoSCC) to identify articles related to glioma methylation published from January 1, 2004, to December 31, 2023. The analysis included full-text publications in the English language and excluded non-research publications. Analysis and visualization were performed using GraphPad Prism, CiteSpace, and VOSviewer software. The search identified 3,744 publications within the WoSCC database, including 3,124 original research articles and 620 review articles. The research output gradually increased from 2004 to 2007, followed by a significant increase after 2008, which peaked in 2022. A minor decline in publication output was noted during 2020-2021, potentially linked to the coronavirus disease 2019 pandemic. The United States and China were the leading contributors, collectively accounting for 57.85% of the total research output. The Helmholtz Association of Germany, the German Cancer Research Center (DKFZ), and the Ruprecht Karls University of Heidelberg were the most productive institutions. The Journal of Neuro-Oncology led in terms of publication volume, while Neuro-Oncology had the highest Impact Factor. The analysis of publishing authors revealed Michael Weller as the most prolific contributor. The co-citation network analysis identified David N. Louis's article as the most frequently cited. The keyword analysis revealed "temozolomide," "expression," "survival," and "DNA methylation" as the most prominent keywords, while "heterogeneity," "overall survival," and "tumor microenvironment" showed the strongest citation bursts. The findings of this study illustrate the increasing scholarly interest in glioma methylation, with a notable increase in research output over the past two decades. This study provides a comprehensive overview of the research landscape, highlighting the importance of temozolomide, DNA methylation, and the tumor microenvironment in glioma research. Despite its limitations, this study offers valuable insights into the current research trends and potential future directions, particularly in the realm of immunotherapy and epigenetic editing techniques.

Genome editing for improvement of biotic and abiotic stress tolerance in cereals

Global agricultural production must quadruple by 2050 to fulfil the needs of a growing global population, but climate change exacerbates the difficulty. Cereals are a very important source of food for the world population. Improved cultivars are needed, with better resistance to abiotic stresses like drought, salt, and increasing temperatures, and resilience to biotic stressors like bacterial and fungal infections, and pest infestation. A popular, versatile, and helpful method for functional genomics and crop improvement is genome editing. Rapidly developing genome editing techniques including clustered regularly interspaced short palindromic repeats (CRISPR) and CRISPR-associated protein (Cas) are very important. This review focuses on how CRISPR/Cas9 genome editing might enhance cereals’ agronomic qualities in the face of climate change, providing important insights for future applications. Genome editing efforts should focus on improving characteristics that confer tolerance to conditions exacerbated by climate change (e.g. drought, salt, rising temperatures). Improved water usage efficiency, salt tolerance, and heat stress resilience are all desirable characteristics. Cultivars that are more resilient to insect infestations and a wide range of biotic stressors, such as bacterial and fungal diseases, should be created. Genome editing can precisely target genes linked to disease resistance pathways to strengthen cereals’ natural defensive systems.

Abstract 74: The rs1173771 Haplotype Associated with Blood Pressure Influences Chromatin Interactions Involving the Natriuretic Peptide Receptor 3 Gene Promoter

Determining the mechanisms of action for human blood pressure (BP) variants in the noncoding regions of genome, particularly large haplotypes containing multiple variants, is both critical and challenging. Human BP-associated rs1173771 locus includes a haplotype containing 11 single nucleotide polymorphisms (SNPs) spanning 17.4 kbp. The Linkage Disequilibrium (LD) region is approximately 126 kbp from the transcription start site of the closest protein-coding gene NPR3 (natriuretic peptide receptor 3). We used genome editing and region-capture Micro-C to examine the effect of the rs1173771 haplotype on the expression of neighboring genes and the chromatin mechanisms involved. The BP-elevating and -lowering haplotypes of rs1173771 locus were precisely reconstituted in human induced pluripotent stem cells (iPSCs) using an efficient, two-step genome editing technique. We then differentiated the edited iPSCs to endothelial (iEC) and vascular smooth muscle cells (iVSMC). The BP-elevating haplotype significantly (p ≤ 0.05) decreased NPR3 expression in iEC and iVSMC. Using region capture Micro-C targeting the rs1173771 haplotype region and the promoter regions of neighboring genes, we found in both iECs and iVSMCs, the BP-elevating rs1173771 haplotype increased chromatin contacts between the rs1173771 haplotype region and NPR3 promoter region, compared to the BP-lowering haplotype. Statistical comparison of chromatin interaction using HiCCompare showed the interactions of a genomic segment overlapping the 5’ end of the rs1173771 haplotype region with the NPR3 promoter region and a region just upstream of the promoter were 10 and 6 fold stronger (p.adj ≤ 0.001) in iECs with homozygous BP-elevating haplotype compared to BP-lowering haplotype. Similarly, in iVSMCs, the interaction of a genomic segment overlapping the rs1173771 haplotype region with a region just upstream of the NPR3 promoter was 4 fold stronger (p.adj = 0.02) for homozygous BP-elevating haplotype compared to BP-lowering haplotype. These results suggest that the BP-elevating rs1173771 haplotype interacts with the NPR3 promoter more strongly to suppress NPR3 expression, possibly through the recruitment of inhibitory protein complexes.

Brain-Targeted Cas12a Ribonucleoprotein Nanocapsules Enable Synergetic Gene Co-Editing Leading to Potent Inhibition of Orthotopic Glioblastoma.

Gene-editing technology shows great potential in glioblastoma (GBM) therapy. Due to the complexity of GBM pathogenesis, a single gene-editing-based therapy is unlikely to be successful; therefore, a multi-gene knockout strategy is preferred for effective GBM inhibition. Here, a non-invasive, biodegradable brain-targeted CRISPR/Cas12a nanocapsule is used that simultaneously targeted dual oncogenes, EGFR and PLK1, for effective GBM therapy. This cargo nanoencapsulation technology enables the CRISPR/Cas12a system to achieve extended blood half-life, efficient blood-brain barrier (BBB) penetration, active tumor targeting, and selective release. In U87MG cells, the combinatorial gene editing system resulted in 61% and 33% knockout of EGFR and PLK1, respectively. Following systemic administration, the CRISPR/Cas12a system demonstrated promising brain tumor accumulation that led to extensive EGFR and PLK1 gene editing in both U87MG and patient-derived GSC xenograft mouse models with negligible off-target gene editing detected through NGS. Additionally, CRISPR/Cas12a nanocapsules that concurrently targeted the EGFR and PLK1 oncogenes showed superior tumor growth suppression and significantly improved the median survival time relative to nanocapsules containing single oncogene knockouts, signifying the potency of the multi-oncogene targeting strategy. The findings indicate that utilization of the CRISPR/Cas12a combinatorial gene editing technique presents a practical option for gene therapy in GBM.

DNA contamination within recombinant adeno-associated virus preparations correlates with decreased CD34+ cell clonogenic potential

Recombinant adeno-associated viruses (rAAV) are promising for applications in many genome editing techniques through their effectiveness as carriers of DNA homologous donors into primary hematopoietic stem and progenitor cells (HSPC) but have many outstanding concerns. Specifically, their biomanufacturing and the variety of factors that influence the quality and consistency of rAAV preps are in question. During the process of rAAV packaging, a cell line is transfected with several DNA plasmids that collectively encode all the necessary information to allow for viral packaging. Ideally, this process results in packaging of complete viral particles only containing rAAV genomes; however, this is not the case. Through this study, we were able to leverage Single-Stranded Virus (SSV)-seq, an NGS-based method to quantify all DNA species present within rAAV preps. From this, it was determined that much of the DNA within some rAAV preps is not vector-genome derived, and there is wide variability in the contamination by DNA across various preps. Furthermore, we demonstrate that transducing CD34+ hematopoietic stem and progenitor cells (HSPC) with preps with higher contaminating DNA resulted in decreased clonogenic potential, altered transcriptomic profiles, and decreased genomic editing. Collectively, this study characterized the effects of DNA contamination within rAAV preps on CD34+ HSPC cellular potential.

Therapeutic Gene Editing for Hemoglobinopathies.

In the last ten years, a consistent number of clinical studies have evaluated different gene approaches for the treatment of patients with sickle cell disease (SCD) and transfusion-dependent β-thalassemia (TDT). Initial studies of gene therapy for hemoglobinopathies involved the use of lentiviral vectors to add functional copies of the gene encoding β-globin in defective CD34 cells; more recently, gene editing techniques have been used involving either CRISPR-Cas9, transcription activation-like effector protein nuclease, zinc finger nuclease, and base editing to either induce fetal hemoglobin production at therapeutic levels or to genetically repair the underlying molecular defect causing the disease. Here, we review recent gene editing studies that have started the development of a new era in the treatment of hemoglobinopathies and, in general, monoallelic hereditary diseases.

IPSC-Derived Cardiomyocytes as a Disease Model to Understand the Biology of Congenital Heart Defects.

The discovery of human pluripotent stem cells (hiPSCs) and advances in DNA editing techniques have opened opportunities for personalized cell-based therapies for a wide spectrum of diseases. It has gained importance as a valuable tool to investigate genetic and functional variations in congenital heart defects (CHDs), enabling the customization of treatment strategies. The ability to understand the disease process specific to the individual patient of interest provides this technology with a significant advantage over generic animal models. However, its utility as a disease-in-a-dish model requires identifying effective and efficient differentiation protocols that accurately reproduce disease traits. Currently, iPSC-related research relies heavily on the quality of cells and the properties of the differentiation technique In this review, we discuss the utility of iPSCs in bench CHD research, the molecular pathways involved in the differentiation of cardiomyocytes, and their applications in CHD disease modeling, therapeutics, and drug application.

The Alienation Effect as a Communication Tool: Analyzing "The French Dispatch" Film

Bertolt Brecht's aesthetic theories, including the alienation effect, have been effective in shaping communication with the audience in the realm of cinema. This effect prevents the audience from identifying with the characters, fostering an objective and critical perspective. This study addresses how Brecht's alienation effect from his epic theater theory is utilized in modern cinema. In this context, the functionality of the alienation effect as a communication tool is examined through the film The French Dispatch. The study is structured according to the phenomenological design among qualitative analysis methods. According to the findings, Brecht's alienation effect is effective in determining the dramatic structures of films. The French Dispatch contains elements that evoke this effect. In the film, the direct address of characters to the camera, color changes, editing techniques, and the presence of narrators bring to mind the Brechtian approach. Considering the three separate stories told in the film and their visual and formal characteristics, it has been concluded that the alienation effect, through the communication established with the audience, facilitates the development of a critical approach.

Video Art and Collective Memory in Turkey

The aim of this article is to present and study contemporary video practices since the 2000s in Turkey through the representation of time and collective memory. The article features the four video artists who have structured the video art scene in Turkey: Ali Kazma, Halil Altındere, Erkan Özgen and Seza Paker. This research addresses two interconnected issues: firstly, the purpose is to examine how the distinct technical parameters of video production shape a synthesized temporality. This inquiry naturally gives rise to a secondary purpose: in what manner does this constructed temporality facilitate the exploration of memory and historical discourse? The hypothesis is that the video image, both as a technical artifact and a conceptual construct, inherently possesses its unique framework for temporal construction, thereby actively contributing to novel reinterpretations of collective memory and historiography The methodology involves conducting a formal analysis of the video content. This approach focuses on examining the visual elements, composition, use of color, sound, editing techniques, and overall aesthetics of the video to gain deeper insights into its artistic significance and meaning. By employing formal analysis, the aim of this article is to decipher the visual language employed by the video artists and uncover nuanced layers of interpretation.
