Cannabidiol promotes apoptosis via regulation of XIAP/Smac in gastric cancer.

Image result for cell death and disease“According to recent studies, Cannabidiol (CBD), one of the main components of Cannabis sativa, has anticancer effects in several cancers. However, the exact mechanism of CBD action is not currently understood.

Here, CBD promoted cell death in gastric cancer.

We suggest that CBD induced apoptosis by suppressing X-linked inhibitor apoptosis (XIAP), a member of the IAP protein family. CBD reduced XIAP protein levels while increasing ubiquitination of XIAP. The expression of Smac, a known inhibitor of XIAP, was found to be elevated during CBD treatment. Moreover, CBD treatment increased the interaction between XIAP and Smac by increasing Smac release from mitochondria to the cytosol. CBD has also been shown to affect mitochondrial dysfunction.

Taken together, these results suggest that CBD may have potential as a new therapeutic target in gastric cancer.”

“In conclusion, our study showed that CBD induces apoptotic cell death in gastric cancer cells, which is triggered by ER stress generation and subsequent XIAP inhibition by Smac. Taken together, our results suggest the potential of CBD in novel treatments against gastric cancer.”
