1 Nrf2-mediated adaptive response to methyl glyoxal in HepG2 cells involves the induction of AKR7A2. Pyruvaldehyde aldo-keto reductase family 7 member A2 Homo sapiens
2 We have shown that treating HepG2 cells with sub-lethal concentrations of MG increases the level of NADPH:quinone oxidoreductase (NQO1) mRNA by 4.5-fold, AKR1C3 mRNA by 14-fold and AKR7A2 mRNA by 4-fold. Pyruvaldehyde aldo-keto reductase family 7 member A2 Homo sapiens
3 Levels of AKR7A2 protein are increased by 2.1- and 1.8-fold following 9h and 24h exposure of cells to 50 muM MG. Pyruvaldehyde aldo-keto reductase family 7 member A2 Homo sapiens
4 Knockdown of AKR7A2 in HepG2 shows that AKR7A2 is responsible for up to 50% of the protection against MG toxicity in HepG2 cells. Pyruvaldehyde aldo-keto reductase family 7 member A2 Homo sapiens
5 Knockdown of AKR7A2 in HepG2 shows that AKR7A2 is responsible for up to 50% of the protection against MG toxicity in HepG2 cells. Pyruvaldehyde aldo-keto reductase family 7 member A2 Homo sapiens
6 In conclusion, these findings indicate that protective enzymes are significantly up-regulated in response to low concentrations of MG in HepG2 cells and that AKR7A2 contributes to protection against MG-induced toxicity. Pyruvaldehyde aldo-keto reductase family 7 member A2 Homo sapiens
