Changes in the expression of ER stress-related genes in PDLSCs after D-glucose stimulation at different concentrations. The mRNA expression of GRP78 (A), ATF6 (B), PERK (C), and XBP1 (D) in PDLSCs after stimulation with different concentrations of D-glucose. *, P<0.05, **, P<0.01, ***, P<0.001 compared with the 5.6 mM D-glucose (control) group at the same time point. #, P<0.05, ###, P<0.001 compared with 6 hours after stimulation with the same D-glucose concentration. ER, endoplasmic reticulum; PDLSCs, periodontal ligament stem cells; mRNA, messenger ribonucleic acid; GRP78, glucose regulated protein 78; ATF6, activating transcription factor 6; PERK, double-stranded RNA-activated protein kinase (PKR) like endoplasmic reticulum kinase; XBP1, X box-binding protein 1.
