Abstract:
Research indicates that FAM65A is significantly involved in tumorigenesis. Nevertheless, the prognostic implications of FAM65A expression levels and its contribution to CRC malignant progression have yet to be elucidated. Here, we revealed that FAM65A is overexpressed in CRC tissues and is linked to various pathological indicators and patient prognosis. Importantly, Cox regression analysis indicated that FAM65A may function as an independent prognostic marker. Furthermore, functional assays conducted in vitro demonstrated that FAM65A enhanced CRC cell proliferation and migration, alongside decreased apoptosis. Mechanistically, we elucidated that FAM65A binds to Ras and activates the Ras/extracellular regulated protein kinases (ERK) signaling to mediate RSK activation contributes to CRC progression, treatment with the Ras inhibitor Abd-7 or RSK inhibitor BRD7389 effectively countered the FAM65A-mediated enhancement of malignancy. Additionally, in vivo experiments indicated that FAM65A knockdown led to the inhibition of Ras/ERK/RSK activation and subsequently impeded CRC progression. Our study provides targets and strategies for the treatment of CRC.
