Role of SMC1A overexpression as a predictor of poor prognosis in late stage colorectal cancer.

ABSTRACT:

Background

Structural maintenance of chromosomes 1A (SMC1A) is a member of the cohesion family of proteins that plays crucial roles in cell cycle control. Recent studies have concluded that SMC1A is involved in the pathogenesis of cancer. This study aims to evaluate the functional role of SMC1A in colorectal cancer (CRC) both in vitro and in vivo, and the underlying molecular mechanisms.

Methods

We firstly investigated the expression levels of SMC1A in 427 CRC specimens. Antigen expression was determined by immunohistochemical analysis of SMC1A on tissue microarrays. Stable SMC1A knockdown CRC cell lines were employed. The effects of SMC1A depletion on cell growth in vitro were examined by MTT, colony formation and flow cytometry assays. Tumor forming was evaluated by nude m
