Oral exosome-like nanovesicles from Phellinus linteus suppress metastatic hepatocellular carcinoma by reactive oxygen species generation and microbiota rebalancing.

The biomedical application of nanotechnology in cancer treatment has demonstrated significant potential for improving treatment efficiencies and ameliorating adverse effects. However, the medical translation of nanotechnology-based nanomedicines faces challenges including hazardous environmental effects, difficulties in large-scale production, and possible excessive costs. In the present study, we extracted and purified natural exosome-like nanoparticles (ELNs) from Phellinus linteus. These nanoparticles (denoted as P-ELNs) had an average particle size of 154.1 nm, displayed a negative zeta potential of -31.3 mV, and maintained stability in the gastrointestinal tract. Furthermore, P-ELNs were found to contain a diverse array of functional components, including lipids and pharmacologically active small-molecule constituents. In vitro investigations suggested that they exhibited high internalization efficiency in liver tumor cells (Hepa 1-6) and exerted significant anti-proliferative, anti-migratory, and anti-invasive effects against Hepa 1-6 cells. Strikingly, the therapeutic outcomes of oral P-ELNs were confirmed in an animal model of metastatic hepatocellular carcinoma by amplifying reactive oxygen species (ROS) and rebalancing the gut microbiome. These findings demonstrate the potential of P-ELNs as a promising oral therapeutic platform for liver cancer treatment.

Zinc Oxide Nanoparticles and Cancer Chemotherapy: Helpful Tools for Enhancing Chemo-sensitivity and Reducing Side Effects?

Cancer chemotherapy is still a serious challenge. Chemo-resistance and destructive side effects of chemotherapy drugs are the most critical limitations of chemotherapy. Chemo-resistance is the leading cause of chemotherapy failure. Chemo-resistance, which refers to the resistance of cancer cells to the anticancer effects of chemotherapy drugs, is caused by various reasons. Among the most important of these reasons is the increase in the efflux of chemotherapy drugs due to the rise in the expression and activity of ABC transporters, the weakening of apoptosis, and the strengthening of stemness. In the last decade, a significant number of studies focused on the application of nanotechnology in cancer treatment. Considering the anti-cancer properties of zinc, zinc oxide nanoparticles have received much attention in recent years. Some studies have indicated that zinc oxide nanoparticles can target the critical mechanisms of cancer chemo-resistance and enhance the effectiveness of chemotherapy drugs. These studies have shown that zinc oxide nanoparticles can reduce the activity of ABC transporters, increase DNA damage and apoptosis, and attenuate stemness in cancer cells, leading to enhanced chemo-sensitivity. Some other studies have also shown that zinc oxide nanoparticles in low doses can be helpful in minimizing the harmful side effects of chemotherapy drugs. In this article, after a brief overview of the mechanisms of chemo-resistance and anticancer effects of zinc, we will review all these studies in detail.

Synthesis of folic acid-conjugated glycodendrimer with magnetic β-cyclodextrin core as a pH-responsive system for tumor-targeted co-delivery of doxorubicin and curcumin

One of the most important applications of nanotechnology in cancer treatment involves the design of magnetic nanocomposites for the targeted delivery of anticancer drugs to cancer cells. This study aims to develop a novel, appropriate, and efficient magnetic carrier having antioxidant properties for the controlled release of anticancer drugs, hydrophilic doxorubicin (DOX), and hydrophobic curcumin (CUR) to cancer cells using folic acid conjugated with magnetic glycodendrimer (Fe 3 O 4 -β-CD-CTD-FA). The synthesized carrier was characterized using DLS, EDX, XRD, BET, FT‐IR, Zeta potential, VSM, TEM, and SEM analysis. The TEM results showed that synthesized Fe 3 O 4 -β-CD-CTD-FA have a spherical-like core-shell structure with an average diameter of approximately 533 nm. The encapsulation efficiency (EE) of Fe 3 O 4 -β-CD-CTD-FA was found to be 98.96% for DOX and 70.91% for CUR. The release studies of DOX and CUR from Fe 3 O 4 -β-CD-CTD-FA showed that maximum release occurs at pH 5 which means it has a controlled pH-responsive behavior. In vitro cytotoxicity and confocal microscopy of the as-synthesized Fe 3 O 4 -β-CD-CTD-FA in MDA-MB-231 cells clearly showed that the prepared carrier had no significant cytotoxicity and could easily enter the cell. Furthermore, the in vitro antioxidant capacity of Fe 3 O 4 -β-CD-CTD-FA was evaluated by DPPH assay and the results exhibited that the synthesized carrier has excellent antioxidant activity (75.45%). Therefore, the obtained glycodendrimer in this study due to their target ability under a magnetic field, excellent biocompatibility, good colloidal stability, simple preparing method, and good antioxidant activity could be used as a promising targeted co-drug delivery system for cancer therapy. • Fe 3 O 4 -β-CD-CTD-FA nanocomposite with antioxidant properties successfully prepared. • The resulted nanocomposite was applied for co-delivery of DOX and CUR to breast cancer cells. • In vitro cytotoxicity and confocal microscopy illustrated that the nanocomposite had no significant cytotoxicity and could easily enter the cells.

Gold Nanoparticles for BCR-ABL1 Gene Silencing: Improving Tyrosine Kinase Inhibitor Efficacy in Chronic Myeloid Leukemia.

Introduction of tyrosine kinase inhibitors for chronic myeloid leukemia treatment is associated with a 63% probability of maintaining a complete cytogenetic response, meaning that over 30% patients require an alternative methodology to overcome resistance, tolerance, or side effects. Considering the potential of nanotechnology in cancer treatment and the benefits of a combined therapy with imatinib, a nanoconjugate was designed to achieve BCR-ABL1 gene silencing. Gold nanoparticles were functionalized with a single-stranded DNA oligonucleotide that selectively targets the e14a2 BCR-ABL1 transcript expressed by K562 cells. This gold (Au)-nanoconjugate showed great efficacy in gene silencing that induced a significant increase in cell death. Variation of BCL-2 and BAX protein expression, an increase of caspase-3 activity, and apoptotic bodies in cells treated with the nanoconjugate demonstrate its aptitude for inducing apoptosis on K562 BCR-ABL1-expressing cells. Moreover, the combination of the silencing Au-nanoconjugate with imatinib prompted a decrease of imatinib IC50. This Au-nanoconjugate was also capable of inducing the loss of viability of imatinib-resistant K562 cells. This strategy shows that combination of Au-nanoconjugate and imatinib make K562 cells more vulnerable to chemotherapy and that the Au-nanoconjugate alone may overcome imatinib-resistance mechanisms, thus providing an effective treatment for chronic myeloid leukemia patients who exhibit drug tolerance.
