Our findings for the first time reveal a novel role of ABHD5 in regulating lysosome function, highlighting the significance of ABHD5 as a compelling biomarker predicting the sensitivity of CRCs to FU-based chemotherapy.
Taken together, our findings show that macrophage ABHD5 suppresses NFκB-dependent MMP production and cancer metastasis and may serve as a prognostic marker in colorectal cancer.
Alpha-beta Hydrolase Domain Containing 5 (ABHD5) is a key regulator of intracellular neutral lipids that has been recently identified as a tumor suppressor in colorectal cancer, yet its potential role in PCa has not been investigated.
Our findings suggest that ABHD5 possesses a PNPLA2-independent function in regulating autophagy and tumorigenesis, further establishing the tumor suppressor role of ABHD5, and offering an opportunity to develop new approaches aimed at preventing CRC carcinogenesis.
