英文摘要Focal adhension kinase (FKA) is a key component of the signal transduction pathways triggered by integrins and activation of FAK lead to acts on potential substrates paxiUin and pl30Cas, which causes increases cell migration and potentially regulates cell proliferation. To investigate the effects of the two signal molecules on anoikis (apoptosis that occurs in cells that are detached from matrix). RNA interference technolgy was applied to silence the genes of the two proteins in gastric cancer cell line BGC823 and observed the the effects on ceU anchorage independent growth. According to the mechanism of RNAi technology, two target sequences of paxillin and pl30Cas gene were designed and subsequently, two vectors (pWHl-/)130cas, pWHl-paxilin) were constructed.Following trasient transfected into BGC823 cell line cultured both in adhence and suspension, the mRNA and protein expression level of the two genes were significantly decreased by RT-PCR and Western blot assay. Furthermore, the inverted phase contrast microscope demonstrated that the attached BGC823 cell shrank and detached from the matrix and that clustering phenomenon of suspended cells were inhibited following the two molecules were being silenced, respectively. MTT assay also showed that the survival rate of the detached BGC823 pWHl-paxillin and GGC823 pWHl-pl30Cas were markedly decrease to 32.19% and 28,52% as compared with control group (P < 0.01) .This was mainly due to the enhanced Gl phase as demonstrated by FCM assay.The above results suggested that pl30Cas and paxillin have played an important role in the gastric cancer cell resistant to anoilks.
