β-蜕皮甾酮调控BMSCs自噬促进成骨分化的作用
Effects of β-ecdysterone in regulating BMSCs autophagy and promoting osteogenic differentiation
摘要
Abstract
Objective To investigate the intervention effect and mechanism of β-ecdyssterone on the osteogenic differentiation of rat bone marrow mesenchymal stem cells(BMSCs)based on the regulation of autophagy by the adenosine 5'-monophosphate kinase-activated protein(AMPK)/mammalian target of rapamycin(m TOR).Methods BMSCs cells were divided into control group(normal culture),low-,middle-and high-dose groups(intervened with 0.01,0.10 and 1.00 μmol·L-1ecdysterone).The expression of cell genes was determined by real-time quantitative polymerase chain reaction(qRT-PCR);and the relative expression level of cell proteins was determined by immunofluorescence(IF).Results The relative expression levels of alkaline phosphatase(ALP)mRNA in the control group,low-,middle and high-dose groups were 1.01±0.14,1.22±0.05,1.28±0.05,1.59±0.20;the relative protein expression levels of Runt-related transcription factor 2(RUNX2)mRNA were 1.00±0.07,1.45±0.07,2.11±0.32,4.67±1.45;the relative protein expression levels of phosphorylated AMPK protein were 0.07±0.01,0.11±0.01,0.06±0.01,0.18±0.01;and the relative protein expression levels of Sequestosome 1(p62/SQSTM1)protein were 1.72±0.02、1.67±0.02、0.94±0.01、0.04±0.01;the relative protein expression levels of p-mTOR protein were 0.66±0.01,0.40±0.01,0.42±0.01,0.04±0.01;and the relative protein expression levels of microtubule-associated protein 1 light chain 3 beta(LC3 B)protein were 0.07±0.01,0.20±0.01,0.87±0.05,1.27±0.04,respectively.There were statistically significant differences between the low-,middle-,and high-dose groups and the control group(P<0.05,P<0.001).Conclusionβ-ecdyssterone can regulate autophagy and promote osteogenic differentiation of BMSCs by activating the AMPK/mTOR pathway.关键词
