System Xc − : a key regulatory target of ferroptosis in cancer

xlomafota.13 shared this article with you from Inoreader System Xc − : a key regulatory target of ferroptosis in cancer Via Latest Results for Investigational New Drugs Summary Ferroptosis is a type of oxidative stress-dependent regulated necrosis characterized by excessive lipid peroxide accumulation. This novel cell death modality has been implicated in preventing cancer progression. Cancer cells tend to modulate their redox state to prevent excessive peroxidation, eventually facilitating tumor growth. System Xc− (a cystine/glutamate antiporter system) is a promising target in cancer cells for ferroptosis induction. The overexpression of system Xc−, especially its core subunit xCT, has been reported in several tumors, and these high expression levels were closely related to cancer cell proliferation, invasion, metastasis and the tumor microenvironment. xCT might serve as a novel biomarker, and its upregulation almost always indicates drug tolerance and poor survival. Therefore, system Xc− inhibition may enhance chemotherapy sensitivity and optimize patient prognosis. Here, we elaborate on the med iation of ferroptosis by suppressing system Xc− and the relevant underlying molecular mechanism in cancer cells. The spotlight on this approach to cancer treatment is creating a new horizon and pointing to future opportunities. View on the web Inoreader. Take back control of your news feed.
