After 48 h of incubation of ANDR and GC cells, real-time PCR was employed to examine the expression of genes with roles in cell invasion (TIMP-1, TIMP-2, MMP-2, MMP-9, and CD147) and in apoptosis and survival (Bcl-2, Bax, Bik, and survivin). This evidence concerns the gene TIMP1 and gastric cancer.
