HRT, Herbal Formula, Induces G2M Cell Cycle Arrest and Apoptosis via Suppressing Akt Signaling Pathway in Human Colon Cancer Cells

الملخص EN

We have demonstrated the anticancer effect of HRT in HCT116, human colon carcinoma cells.

HRT inhibited cancer cell growth by causing cell cycle arrest at G2/M and inducing apoptosis as evidenced by DNA fragmentation assay.

We found that HRT induces the activation of caspase-3, -8, and -9, whereas it reduces the level of Bcl-2 protein and results in the cleavage of PARP.

Further, HRT decreased the level of phosphorylation of Akt and its downstream signals such as mTOR and GSK-3β.

These results indicate that HRT stimulates the apoptotic signaling pathway and represses the survival and proliferation of colon cancer cells via inhibiting Akt activity.

Hence, our results suggest that HRT has a potential to be developed as a therapeutic agent against colon cancer cells.
