In Figure 4C, the apoptotic protein caspases 3/7 (Cas 3/7) activity of the combined treatment (UVC30/CHW09-50) for oral cancer Ca9-22 and CAL 27 cells were higher than individual treatments and the untreated control after 24 h as indicated by ELISA assays. Here, CASP3 is linked to lip and oral cavity carcinoma.
