Aims
Little is known about the role of chromosome 12 open reading frame 49 (C12ORF49)-induced metabolic signal transduction in tumor growth. We investigated the relationship between C12ORF49 expression and prognosis in colorectal cancer (CRC) patients.
Background and aims
Little is known about the role of chromosome 12 open reading frame 49 (C12ORF49)-induced metabolic signal transduction in tumor growth. We investigated the relationship between C12ORF49 expression and prognosis in colorectal cancer (CRC) patients.
Conclusions
Our results suggest that C12ORF49 plays a key role in CRC tumor growth.
Methods
C12ORF49 protein expression was measured in CRC tissues by Western blot and immunohistochemistry staining. Knock out of C12ORF49 in CRC cells was then performed, and the role of C12ORF49 in CRC cell proliferation and growth was examined. The expression of C12ORF49 in CRC was analyzed in Gene Expression Profiling Interactive Analysis (GEPIA) databases. A prognosis model with 11 C12ORF49-associated genes (CAGs) was generated by TCGA databases.
Results
C12ORF49 expression was significantly higher in CRC tumor tissue than in non-tumor tissue. Furthermore, in vitro and in vivo loss-of-function experiments, showed that C12ORF49 plays critical roles in promoting tumor cell growth. There was a significant correlation between C12ORF49 protein and the presence of tumor necrosis. C12ORF49 is critical for its interaction with SREBF1, TMEM41A, and S1PR3 in the poor prognosis of CRC. Conclusions: Our results suggest that C12ORF49 plays a key role in CRC tumor growth.
