MYC/TET3-Regulated TMEM65 Activates OXPHOS-SERPINB3 Pathway to Promote Progression and Cisplatin Resistance in Triple-Negative Breast Cancer.

ABSTRACT: Triple-negative breast cancer (TNBC) is the most lethal subtype of breast cancer due to its aggressive clinical features and the lack of effective targeted therapeutics. Mitochondrial metabolism is intimately linked to TNBC progression and therapeutic resistance and is an attractive therapeutic target for TNBC. Here, it is first reported that human transmembrane protein 65 (TMEM65), a poorly characterized mitochondrial inner-membrane protein-encoding gene in human cancer, acts as a novel oncogene in TNBC to promote tumor growth, metastasis, and cisplatin resistance both in vivo and in vitro. Transcription factor MYC and DNA demethylase ten-eleven translocation 3 (TET3) coordinately upregulate TMEM65 in TNBC, and its upregulation is associated with poor patient survival. Moreover, pharmacol
