Vicenin-2 acts as a radiosensitizer of the non-small cell lung cancer by lowering Akt expression.
Non-small cell lung cancer (NSCLC) has a very high rate of incidence and is resistant to chemo- and radiotherapy. Vicenin-2 (VCN-2) is a flavonoid obtained from Ocimum sanctum L. and it has been reported to have radioprotective, anticancer, and radiosensitizing properties. We have conducted this study to check the effect of VCN-2 on the cell viability and the effect on PTEN (Phosphatase and tensin homolog), PI3KCA (Phosphatidylinositol 4, 5-biphosphate 3-kinase catalytic subunit alpha isoform/PI3K 110α subunit), and Akt1 when VCN-2 was used alone and in combination with radiation in the NSCLC cell line NCI-H23 (H23). We have also checked the effect of VCN-2 on various pro- and anti-apoptotic genes and the ultra-morphological changes that occurred in the cells when VCN-2 is used alone and in combination with radiation. VCN-2 was able to lower cancer cell survival and phosphorylated Akt while promoting the expression of pro-apoptotic genes and down-regulating anti-apoptotic genes. We also observed the apoptosis-associated ultra-morphological changes in the VCN-2-treated cells. Our study have demonstrated that VCN-2 can be a potential chemotherapeutic and radiosensitizing agent in NSCLC. © 2018 BioFactors, 45(2):200-210, 2019.

Vicenin-2: a potential radiosensitizer of non-small cell lung cancer cells.
Non-small cell lung cancer (NSCLC) is a major form of cancer and is resistant to chemo- and radio-therapy. Vicenin-2 (VCN-2) is a flavonoid obtained from Ocimum sanctum L. and it has been reported to have radioprotective and anti-cancer properties. This study was conducted to check for the radiosensitizing potential of VCN-2 in the NSCLC cell line, NCI-H23. NCI-H23 cells were exposed to VCN-2 singularly, and to X-rays with and without prior VCN-2 treatment. Cytotoxicity assay, cell proliferation assay, caspase-3 activity assay, DNA fragmentation assay and Western blotting for Rad50, MMP-2 and p21 were performed to investigate the radiosensitizing properties of VCN-2. Fibroblast survival assay was performed using HEK293T cells to check for any adverse effects of VCN-2 on normal fibroblast cell line. VCN-2 singularly and in combination with radiation reduced the surviving cancer cells, increased caspase-3 activity, increased DNA fragmentation, increased the levels of Rad50 and lowered levels of MMP-2 and p21 proteins while being non-toxic and radioprotective to the fibroblast cells. VCN-2 showed a potent radiosensitizing property while also showing a chemotherapeutic property against NSCLC cell line NCI-H23.
