Preliminary Study of the Role F-Box Protein 32 (FBXO32) in Colorectal Neoplasms Through the Transforming Growth Factor beta (TGF-β)/Smad4 Signalling Pathway.

ABSTRACT: BACKGROUND F-box protein 32 (FBXO32) (also known as atrogin-1), a member of the F-box protein family, was recently shown to be a transforming growth factor beta (TGF-β)/Smad4 target gene involved in regulating cell survival. It can be transcriptionally silenced by epigenetic mechanisms in some cancers, but its role in colorectal carcinoma (CRC) is unclear. We investigated the role of FBXO32 in CRC and determined its prognostic significance. MATERIAL AND METHODS We used real-time quantitative PCR, Western blot, and immunohistochemistry to elucidate the role of FBXO32 in clinical specimens and primary CRC cell lines. Differences in patient survival were determined by the Kaplan-Meier method and log-rank test. RESULTS We found that the FBXO32 and SMAD4 levels were higher in normal tissues tha
