SV40 MES 13 cells were cultured and transfected with HMGB1 siRNA or scramble siRNA (Scr-siRNA), followed by high glucose (25 mM) treatment. (A) Determination of protein levels of HMGB1 by Western blot. (B) Cell viability in each group was determined with CCK-8 assay. (C) ELISA was used to detect the production of LDH. (D) Extracellular HMGB1 protein levels were determined by Western blot. (E) Real-time PCR was performed to determine levels of ACSL4, PTGS2, NOX1, and GPX4. *P<0.05, **P<0.01, compared with control. #P<0.05, ##P<0.01, compared with HG group.
