Abstract
[BACKGROUND AND AIMS] Colorectal cancer (CRC) is a common malignant tumor worldwide with a complex pathogenesis and an urgent need for new molecular targets. The aim of this study was to investigate the expression of FAM72A in CRC and its potential mechanism to affect cancer cell proliferation and invasion through regulating cellular pyroptosis.
[METHODS] The expression of FAM72A in various cancers was analyzed by TIMER2.0 and GEPIA2 databases, and its relationship with the prognosis of CRC patients was evaluated. FAM72A was knocked down and overexpressed in CRC cell lines HCT116 and DLD1, respectively, and changes in cell proliferation and invasion ability were assessed by CCK-8, EdU, Transwell, and scratch assays. Meanwhile, the regulatory effects of FAM72A on cellular pyroptosis-associated proteins and inflammatory factors were detected by Western blotting and ELISA, and the role of ROS in FAM72A-regulated cellular pyroptosis and cancer cell behaviors was further explored by N-Acetylcysteine (NAC) intervention assay. Finally, the effect of FAM72A on tumor growth was verified by in vivo nude mouse experiments.
[RESULTS] High levels of FAM72A expression were observed in CRC, linking it to poor prognosis in patients. Knockdown of FAM72A significantly inhibited the proliferation, migration, and invasion of CRC cells and activated cellular pyroptosis, accompanied by the upregulation of NLRP3, Caspase-1, and GSDMD expression and the increased secretion of IL-1β and IL-18. In contrast, overexpression of FAM72A inhibited cell pyroptosis and enhanced cancer cell proliferation and invasion. NAC intervention experiments demonstrated that ROS played a critical role in FAM72A-regulated cell pyroptosis and CRC progression. Furthermore, in vivo experiments showed that knockdown of FAM72A significantly inhibited the growth of subcutaneous transplanted tumors in nude mice.
[CONCLUSION] FAM72A inhibits cellular pyroptosis by decreasing ROS levels, which in turn promotes the proliferation and invasion of CRC cells, and it is expected to be a potential therapeutic target for CRC.
