The effect of sinomenine on ERK1/2, JNK and p38 phosphorylation in LPS-stimulated endothelial cells.
This study was to investigate the effect of sinomenine by LPS-induced MAPK phosphorylation in endothelial cells. Endothelial cells were challenged with different doses LPS and/or treated with sinomenine at three concentrations (1, 5, or 10 μg/mL) in pathological model, drug safety, treatment and prevention experiments. The cells were incubated at 37 °C in a cell incubator total for 24 h. The lysate cells were collected and analyzed the phosphorylation of ERK1/2, JNK and p38 by MAPK phosphoprotein assay whole cell lysate kit. As expected, LPS could significantly elevated phosphorylation of ERK1/2, JNK and p38, but sinomenine not. The results revealed that sinomenine significantly reduced the phosphorylation of ERK1/2 and p38 in treatment experiment, and inhibited phosphorylation of ERK1/2, JNK and p38 in prevention experiment. Our findings demonstrated that sinomenine protects endothelial cells from LPS-induced inflammation, which might be associated with depressing MAPK signaling pathway.

Letters.
Papers from both basic research (methodology, molecular and cellular biology, anatomy, histology, biology, embryology, teratology, normal and pathological physiology, biophysics, pharmacology, pathology and experimental pathology, biochemistry, neurochemistry, enzymology, chronobiology, receptor studies, endocrinology, immunology and neuroimmunology, animal physiology, animal breeding and ethology, human ethology, psychology and others) and from clinical research (neurology, psychiatry and child psychiatry, obstetrics and gynecology, pediatrics, endocrinology, immunology, cardiovascular studies, internal medicine, oncology and others) will be considered.
The Journal publishes Original papers and Review Articles. Brief reports, Special Communications, proved they are based on adequate experimental evidence, Clinical Studies, Case Reports, Commentaries, Discussions, Letters to the Editor (correspondence column), Book Reviews, Congress Reports and other categories of articles (philosophy, art, social issues, medical and health policies, biomedical history, etc.) will be taken under consideration.
