In the present study, we characterize the early cytotoxic effects of 7b-hydroxycholesterol, a major cytotoxin in oxidized LDL, in human aortic smooth muscle cells. Within a few minutes after addition, 7b-hydroxycholesterol induced Ca oscillations with a frequency of :0.3–0.4 min. A few hours later, thapsigargin-sensitive Ca pools were depleted, indicating that 7b-hydroxycholesterol perturbs int...
PURPOSE Age-related cataracts are considered to be a pathological condition that arise as senescence progresses. However, little is known about the function of microRNAs (miRNAs) in the formation of age-related cataracts. The purpose of this study was to identify possible differences in miRNA expression in the central epithelium of transparent and age-related cataractous human lenses. METHODS...
The objective of this study is to design a graphene-based miRNA transfection drug delivery system for antiresorptive therapy. An efficient nonviral gene delivery system is developed using polyethylenimine (PEI) functionalized graphene oxide (GO) complex loaded with miR-7b overexpression plasmid. GO-PEI complex exhibits excellent transfection efficiency within the acceptable range of cytotoxicit...
microRNAs play a critically important role in a wide array of biological processes including those implicated in cancer, neuro-degenerative and metabolic disorders, and viral infection. Although we have begun to understand microRNA biogenesis and function, experimental demonstration of their functional effects and the molecular mechanisms by which they function remains a challenge. Members of t...
