Method for increasing the replication of oncolytic HSVs in highly resistant tumor cells using mTOR pathway and PI3K inhibitors

The present invention is directed to the administration of an HSV derived oncolytic virus and a PI3K / AKT / mTOR pathway inhibitor to treat various types of resistant tumors. Therapy-resistant tumor formation is one of the main causes for treatment failure in the clinic. The treatment methods and compositions disclosed herein sensitize resistant tumors to the treatment of herpes simplex virus (HSV)-based oncolytic virotherapy. Pre or co-treatment of resistant tumor cells with the mTOR inhibitor, rapamycin, or certain PI3K inhibitors, such as LY294002, can efficiently sensitize the tumors to HSV derived oncolytic viruses, whereby the replication and spread of the viruses are dramatically enhanced.

Regulating effect of zuojin wan (ZJW) on ROCK/PTEN/PI3K signal pathway of human gastric cancer drug-resistant cells and application of ZJW

The invention discloses a regulating effect of zuojin wan (ZJW) on a ROCK / PTEN / PI3K signal pathway of human gastric cancer drug-resistant cells and application of ZJW. The influence of ROCK and PI3K signals on ZJW inducing apoptosis and a cycle of the gastric cancer drug-resistant cells is inhibited, and the results show that ZJW can induce apoptosis of SGC7901 / DDP cells. No significant change occurs when Y27623 is applied alone. Apoptosis induction of ZJW and Y27623 combination to the SGC7901 / DDP cells is significantly lower than that of ZJW alone, and it is indicated that activation of the ROCK signals is an important factor for ZJW to induce apoptosis. LY294002 applied alone significantly increases apoptosis of the SGC7901 / DDP cells, and it is indicated that the PI3K signals are inhibitory signals of apoptosis. The induction effect of apoptosis of the SGC7901 / DDP cells by combined use of ZJW and LY294002 is further increased rather than ZJW alone, and it is indicated that the two treatment methods have a synergistic effect.
