Te efect of -tocotrienol, a vitamin E isomer, in modulating gene expression in cellular aging of human diploid fbroblasts was studied. Tese fndings revealed that -tocotrienol may prevent cellular aging of human diploid fbroblasts by modulating gene expression. Introduction limited number of cellular divisions in culture and progres- sively reached a state of irreversible growth arrest, a process Aging is a phenomenon associated with gradual decline in termed as replicative senescence [1]. Cellular changes enlarged and fattened morphology, and showed altered gene that occur in the cell of an organism have direct impact on expression [5]. Cultured human fbroblasts cells displayed the functions of organs, systems and eventually involve the age-dependent transcriptomic diferences.

Many infammation state showed by 2-to 4-fold increase in serum of the selenoproteins are involved in protection against levels of infammatory mediators such as C-reactive protein, oxidative stress or in maintaining cellular redox balance.
