Effect of Bee Venom on Transforming Growth Factor–β1-Treated Hepatocytes
Transforming growth factor (TGF)–β1 induces hepatocyte apoptosis via the mitochondrial permeability transition. However, there is no evidence or information regarding the antiapoptotic effect of BV on hepatocytes.
The authors investigated the antiapoptotic effect of BV on TGF-β1-treated hepatocytes. The results showed significant protection from DNA damage by BV treatment compared to corresponding TGF-β1-treated hepatocytes without BV.
BV suppressed TGF-β1-induced activation of the bcl-2 family and caspase family of proteins, which resulted in inhibition of poly ADP-ribose polymerase (PARP) cleavage. Furthermore, BV is not cytotoxic in the low concentrations used in this study.
Low concentrations of BV potently suppress the apoptotic response in TGF-β1-treated hepatocytes; therefore, BV may have therapeutic potential for the treatment of liver diseases.
