SREBF2 and prostate carcinoma: Mevalonate rescues the effect of statin, but not that of tocotrienol, on prostate cancer cell viability, consistent with tocotrienol-mediated increase in the degradation of nuclear, mature SREBP-2, which maintains cholesterol homeostasis through transcriptional regulation of enzymes in cholesterol biosynthesis and uptake beyond HMGCR (Krycer et al., 2012).
