Custirsen (Cat No.:I025291) is a second-generation antisense oligonucleotide designed to target and inhibit clusterin, a cytoprotective chaperone protein that is often upregulated in response to cancer therapies. By downregulating clusterin expression, Custirsen sensitizes tumor cells to chemotherapy and hormone therapy, enhancing treatment efficacy. It has been studied extensively in prostate, lung, and breast cancers for its ability to overcome therapy resistance and promote apoptosis. Custirsen represents a novel approach in antisense cancer therapeutics, aiming to block stress-induced survival mechanisms in cancer cells and improve clinical outcomes in advanced malignancies.
