CRISPR/Cas9 in the treatment of -thalassemia

Abstract

Based on clinical evidence, medication resistance poses a significant challenge to the treatment of cancer. It causes the disease to become uncontrollable and raises death rates. Drug resistance arises from a variety of causes, but a change in the inherited makeup of tumor cells is typically the root reason. The ability to modify the genome is growing with the recent discovery of clustered regularly interspaced short palindromic repeats (CRISPR)/associated (Cas)9 technology, which may be helpful in reducing drug resistance. Owing to its exceptional accuracy and efficiency, the CRISPR/Cas 9 system has been used to investigate the relevant roles of cancer-causing genes, create animal models of tumors, and identify potential therapeutic targets. As a result, it has emerged as the go-to technique for therapeutic gene editing. Utilizing CRISPR/Cas 9 technologies in the treatment of different diseases is growing. Because oncogene regulation differs from normal gene regulation, the CRISPR/Cas 9 system offers efficient methods for oncogene elimination, interference with expression, and modification of activity, all of which can effectively impede the growth of tumors. This article discusses the potential of the CRISPR/Cas9 system to identify resistance targets in drug-resistant breast cancer and reverse resistance gene alterations. Furthermore, the difficulties that prevent this technology from being clinically applicable and emphasize the CRISPR/Cas9 systems are discussed. The CRISPR/Cas9 system will be a crucial component of personalized medicine and is anticipated to have a significant impact on reducing drug resistance in cancer therapy.
