Growth inhibition of human MDA-mB-231 breast cancer cells by delta-tocotrienol is associated with loss of cyclin D1/CDK4 expression and accompanying changes in the state of phosphorylation of the retinoblastoma tumor suppressor gene product. In addition, epidermal proteins, such as aquaporin-3 (AQP3), also help to retain water content in the SC (Verdier-Svrain and Bont, 2007). This structure allows them to regulate signaling pathways, such as inflammation, cell apoptosis and proliferation (Wallert et al., 2020). Tocotrienols have unique and potent anticancer activity. In addition, TRF was applied topically to the backs of the mice 2h prior to irradiation.

Data extracted from the full-text articles included names of authors, year of publication, study design and major findings of the study. Oxidative stress was induced in the cells via exposure to low doses of hydrogen peroxide. To study the effects of these treatments on pigmentation, the melanin content and tyrosinase enzyme activity were measured. Given the damaging effects of oxidative stress on skin aging, the use of antioxidants to reverse the degenerative effects of the skin is a promising approach to tackle this condition. The synthesis of melanin through the melanogenesis pathway is regulated by the L-tyrosine enzyme tyrosinase. UVA radiation was reported to have a deeper penetration ability, as it can have negative impacts on the cellular and extracellular structure of the dermis layer. Technol. WebThis is because there is significant difference in ratio of tocotrienols to tocopherol in palm based tocotrienols (3.5:1) compared to rice based tocotrienols (1:1).
