Figure 5. H19 repressed ERS in vitro. (A) Immunofluorescence staining exposed the expression of p-PERK and CHOP in four cell groups. (B) The statistical results of relative fluorescence intensity demonstrated the protein expression of p-PERK and CHOP in four cell groups. ##P < 0.05 Low glucose vs. High glucose. **P < 0.05 High glucose+H19 OE vs. High glucose. &&P < 0.05 High glucose vs. High glucose+ Thapsigargin, n = 3/group.
