Cancer&Entry Information

Cancer Name	gastric cancer
ICD-0-3	C16
Methods	qPCR, Western blot, in vitro knockdown
Sample	gastric cancer tissues, cell lines (GES-1, AGS, BGC-823, MKN-45 and SGC-7901)
Expression Pattern	up-regulated
Function Description	The expression of AFAP1-AS1 was significantly increased in the primary tumor tissues of GC patients with lymph node metastasis or tumor node metastasis stage (stage III or IV; P<0.01). ROC curve analysis revealed that the expression of AFAP-AS1, at a cut-off value of 0.5040, could distinguish GC tissues from the matched normal tissues, with an AUC of 0.8802, sensitivity of 81.25% and specificity of 83.75%. The overexpression of AFAP1-AS1 was positively associated with the poor survival rates of GC patients. Furthermore, the downregulation of AFAP1-AS1 significantly inhibited the proliferation, migration and invasion of GC cells in vitro (P<0.01). The decrease in AFAP1-AS1 expression significantly suppressed the expression level of N-cadherin protein in GC cells and increased that of E-cadherin.
