TL;DR
FAM65A overexpression promotes colorectal cancer progression by activating Ras/ERK/RSK signaling and could serve as a prognostic biomarker.
Contribution
FAM65A is identified as a novel independent prognostic marker and driver of CRC progression via Ras/ERK/RSK signaling.
Findings
FAM65A is overexpressed in CRC tissues and correlates with poor prognosis and pathological features.
FAM65A promotes CRC cell proliferation and migration while reducing apoptosis in vitro and in vivo.
FAM65A activates Ras/ERK/RSK signaling, and inhibiting this pathway counteracts its malignant effects.
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…
