Cytosolic cytochrome c represses ferroptosis Song et al. demonstrated that the cytosolic CYCS-INPP4A complex inhibits ferroptosis by promoting phosphatidylinositol-3-phosphate synthesis and preventing phospholipid peroxidation. The small molecule 10A3 disrupts this complex, enhancing ferroptosis-mediated tumor suppression and offering a therapeutic strategy.

TBK1 and IKKε prevent premature cell death by limiting the activity of both RIPK1 and NLRP3 death pathways TBK1 and IKKe prevent premature cell death by limiting the activity of multiple death pathways in myeloid cells.

The loss of TBK1, or both TBK1 and the related kinase IKKε, results in uncontrolled cell death–driven inflammation. We show that TBK1/IKKε prevent premature cell death by limiting the activity of multiple death pathways in myeloid cells. www.science.org/doi/10.1126/...

A decision point between transdifferentiation and programmed cell death priming controls KRAS-dependent pancreatic cancer development - Nature Communications The involvement of cell death pathways in the early stage of pancreatic ductal adenocarcinoma (PDAC) development, especially KRAS-dependent acinar-to-ductal metaplasia (ADM), remains to be investigated. Here, the authors find that TAK1 mediates cell survival during ADM transdifferentiation through suppression of apoptosis and necroptosis, which could be targeted for prevention and treatment of PDAC.
