| Popis: | YAP signaling has been proved to be involved in cell growth, invasion and metastasis in multiple malignancies. But little has been reported about the effects of YAP transduction on gastric cancer metastases. The present study was aimed to explore the effects of shRNA-mediated targeting of YAP gene on human gastric cancer metastases in severe combined immune deficiency (SCID) mice. Human gastric carcinoma cell line SGC7901 was implanted into the stomach of SCID mice, which were randomly divided into 3 groups (n=10). Via intraperitoneal injection, mice received YAP-shRNA, negative control, or normal saline respectively. The results of TUNEL and FQ-PCR showed an obvious induction of apoptosis in the YAP-shRNA group. Intratumoral vascular density and lymphatic density were suppressed in the YAP-shRNA group. In conclusion, silencing of YAP gene effectively induces the cell apoptosis and inhibits microvascular angiogenesis and lymphagiogenesis of gastric cancer cells in vivo , suggesting that YAP may serve as a promising therapeutic target for treatment of cancer. |
