Photoprotective Effects of Cycloheterophyllin against UVA-Induced Damage and Oxidative Stress in Human Dermal Fibroblasts.

Ultraviolet (UV) radiation, particularly ultraviolet A (UVA), is known to play a major role in photoaging of the human skin. Many studies have demonstrated that UV exposure causes the skin cells to generate reactive oxygen species and activates the mitogen-activated protein kinase (MAPK) pathway. Previous studies have also demonstrated that cycloheterophyllin has an antioxidant effect and can effectively scavenge free radicals.

Low p21 level is necessary for the suppressive effects of micoRNA-31 on glioma cell migration and invasion.

MicroRNAs (miRNAs), a kind of endogenous non-coding RNAs, regulate gene expression through binding to the 3'-untranslational region (UTR) of target messenger RNAs (mRNAs) and act as endogenous agents of RNA interference, resulting in either mRNA degradation or translational repression. MiR-31 has been demonstrated to be associated with the development and progression of glioma. However, the underlying molecular mechanism remains largely unclear.
