چکیده انگلیسی
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 aims of this study were 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 messenger RNA levels of BCAT1 were validated by immunohistochemistry and real-time quantitative polymerase chain reaction in GC tissues and adjacent noncancerous tissues. Our study shows that the expression of BCAT1 significantly increased in human GC. Furthermore, it can also be found that BCAT1 overexpression was associated with TNM stage (P < .05), local invasion (P < .05), Lauren type (P < .05), tumor classification (P < .05), lymph node metastasis (P < .05), and presence of distant metastasis (P < .05). Kaplan-Meier survival analysis revealed that high BCAT1 expression predicted significantly worse overall survival (P < .05), whereas multivariate Cox regression analysis showed that BCAT1 affects GC independently. In conclusion, up-regulation of BCAT1 indicated a poor survival rate of GC and may serve as a useful marker for predicting the outcome of patients with GC.
