Abstrakt:	CD147 is a tumor-associated glycoprotein that regulates cell metabolism. However, CD147 methylation and its subsequent role in cancer cell metabolism remain unclear. Here, we detect CD147 di-methylation in 16 non-small-cell lung cancer (NSCLC) tissues using liquid chromatography-tandem mass spectrometry. CD147 is di-methylated to CD147-K234me2 by lysine methyltransferase 5A (KMT5A). The increase in KMT5A expression boosts the levels of CD147-K234me2, further promoting the interaction between CD147 and monocarboxylate transporter 4 (MCT4), which enhances the translocation of MCT4 from the cytoplasm to the membrane. Overexpression of CD147-K234me2 and KMT5A enhances glycolysis and lactate export in NSCLC cells. Clinical analysis shows that high CD147-K234me2 expression is significantly related to cancer progression and overall survival, and has prognostic significance in individuals with NSCLC, especially for those in the early stages. Our findings indicate that CD147-K234me2 plays a critical role in cancer metabolism, and it can be a highly promising therapeutic target for NSCLC.
