Additionally, Sundarraj et al. [16] demonstrated in vitro results that support the ethnomedical use of γ-sitosterol against cancer through the growth inhibition and cell cycle arrest on the apoptosis of cancer cells in accord with Endrini et al. [17], which showed that γ-sitosterol was cytotoxic against colon and liver cancer cell lines and that this effect was mediated by downregulation of c-myc expression and induction of the apoptotic pathways. This evidence concerns the gene MYC and cancer.
