Long noncoding RNA X-inactive specific transcript regulates NLR family pyrin domain containing 3/caspase-1-mediated pyroptosis in diabetic nephropathy

Figure 3 Silencing X inactive specific transcript in diabetic nephropathy can inhibit renal tubular epithelial cell pyroptosis in high glucose-induced HK2 cells. si-NC or si- X inactive specific transcript (XIST) was delivered into HK2 cells treated with high glucose. A: The XIST expression detected by qRT-PCR; B: Enzyme-linked immunosorbent assay detected the expression of IL-1β and IL-18; C: Western blot tested the levels of NLR family pyrin domain containing 3, ASC, Cleaved Caspase-1, Caspase-1, GSDMD, and GSDMD-N; D: Cell viability; E: Lactate dehydrogenase activity. The cell experiment was performed in triplicate. The data were described as mean ± SD and analyzed by one-way ANOVA (A/D-E) or two-way ANOVA (B/C) and Tukey's multiple comparisons test; ^aP < 0.05. NG: Normal glucose; HG: High glucose; si: Small interfering RNA; XIST: X inactive specific transcript; LDH: Lactate dehydrogenase; NLRP3: NLR family pyrin domain containing 3; SC: Apoptosis speck-like protein; GSDMD: Gasdermin D.
