Over-expression of BCAT1 is a prognostic marker in gastric cancer

As one form of branched chain amino-acid transaminase(BCAT) enzymes, It has been found that up-regulation of BCAT1 is associated with poor prognosis in numerous types of tumors, but studies on the role of BCAT1 expression in gastric cancer(GC) are rare. The aim of this study was to detect BCAT1 expression in (GC) and to analyze its association with prognosis of GC patients.Microarray experiments were performed on the Affymetrix U133 plus 2.0 GeneChip Array. The protein and mRNA levels of BCAT1 were validated by immunohistochemistry (IHC) and Real-Time quantitative PCR (RT-qPCR) in GC tissues and adjacent noncancerous tissues (ANCT).
