Abstract

Background and purpose

The botanical formula LCS101 has been shown in clinical research to reduce chemotherapy-induced toxicities. In pre-clinical research, the formula demonstrated selective anti-cancer effects, in part as a result of radical oxygen species (ROS) activity of the botanical components. The present study examined the interaction between LCS101 and radiation therapy on cancer cell lines.

Methods

Incremental doses of LCS101 were added to breast adenocarcinoma (MCF7), prostate (DU145), transitional cell bladder carcinoma (T24), pancreatic epithelioid carcinoma (PANC-1), and osteosarcoma (U20S) cell lines 4 h after single-dose irradiation (range 0.5–4 Gy). Cell viability was tested using sulforhodamine B (SRB) assay after 1 week, with ROS activity examined using 1 mM of the ROS scavenger sodium pyruvate (ROS scavenger), testing cell viability with an SRB assay.

Results

The addition of LCS101 to MCF7 (breast) and DU-145 (prostate) cancer cell lines resulted in a dose-dependent increase in the antiproliferative effects of radiation treatment. The addition of pyruvate inhibited radiation-induced cell death in all of the cell lines treated with LCS101.

Conclusions

The addition of the botanical formula LCS101 to irradiated cancer cells results in an apparent additive effect, most likely through a ROS-mediated mechanism. These findings support the use of LCS101 by patients undergoing radiation therapy, for both its clinical as well as anti-cancer effects.
