OBJECTIVE:To study the effect of dihydromyricetin(DMY)on high glucose(HG)-induced glomerular mesangial cell(MCs)proliferation and fibronectin(FN)accumulation,and explore its mechanism for diabetic nephropathy glomerulosclero-sis. METHODS:Cells were divided into normal group(5.5 mmol/L glucose),HG group(30 mmol/L glucose),DMY low-concen-tration,medium-concentration,high-concentration groups (30 mmol/L glucose+22.5,45,90 μmol/L DMY). After incubating 48 h,MTT was used to detect the proliferative activity [reflected by the optical density(OD)value] of cells;molecular docking meth-od was adopted to conduct simulation analysis for DMY binding state with Smad2. Cells were divided into normal group(5.5 mmol/L glucose),HG group (30 mmol/L glucose),DMY group (30 mmol/L glucose+45 μmol/L DMY) and DMY control group (5.5 mmol/L glucose+45 μmol/L DMY). After incubating 5 h,Western blot was used to detect the expression levels of phosphorylated Smad2 (p-Smad2) and extracellular matrix protein FN. RESULTS:Results of MTT detection showed,compared with normal group,OD values in HG group were significantly increased(P<0.05);compared with HG group,OD values in DMY each con-centration group were significantly reduced(P<0.05). The Gibbs free energy(ΔG)of DMY and Smad2 protein was -5.64 kJ/mol, Ki was 73.53 μmol/L,and there were hydrogen bond donor and receptor binding in No. 465,464,461,458 amino acid residues. Results of Western blot showed,compared with normal group,expression levels of p-Smad2 and extracellular matrix protein FN in HG group were significantly increased (P<0.05);compared with HG group,expression levels of p-Smad2 and extracellular ma-trix protein FN in DMY group were significantly decreased(P<0.05). CONCLUSIONS:DMY inhibits HG-induced MCs prolifera-tion and improves diabetic nephropathy glomerulosclerosis by combining with Smad2 and inhibiting Smad2 phosphorylation to re-duce the extracellular matrix protein FN expression.

Effects of MAPKs signaling on heat stress-induced apoptosis of pulmonary microvascular endothelial cells and its mechanism / 解放军医学杂志

Objective To investigate the effect of mitogen-activated protein kinases (MAPKs) activation on the heat stressinduced apoptosis of pulmonary microvascular endothelial cells (PMVECs).Methods A mouse model of severe heat stroke was made and TUNEL and immunohistochemistry were employed to detect lung tissue damage.MACS separation was used for isolation of neonatal PMVECs,and TUNEL was utilized to detect the apoptosis of PMVECs.Western blotting was used for determining the MAPKs activation during heat stress recovery (0,2,6h).The monolayer permeability of endothelial cells was detected in terms of transmembrane resistance (TEER) and horseradish peroxidase (HRP).Cells were pretreated with MAPKs activation inhibitors to examine the effect of heat stress on the monolayer cell permeability and apoptosis.Results In mice with severe heat stroke,extensive apoptosis of PMVECs was found in their pulmonary tissues.TUNEL revealed that the number of apoptotic cells increased over time during heat stress recovery period and heat stress could activate MAPKs in PMVECs.Compared with heat stress group,in the cells pretreated with p38 or ERK activation inhibitor PD98059 and SB203580,the monolayer permeability and apoptosis increased while in cells pretreated withJNK inhibitor SP600125,the cellular permeability and apoptosis decreased.Conclusion In mice with severe heat stoke,PMVECs might experience apoptosis and p38 and ERK could inhibit apoptosis while JNK could promote apoptosis.
