FIG. 1.
Effect of hydrogen sulfide (H2S) supplementation on expression of glutamate–cysteine ligase catalytic subunit (GCLC) (top) and glutamate–cysteine ligase modifier subunit (GCLM) (bottom) in monocytes treated with control or high glucose (HG). Values are mean±standard error (SE) of three experiments. HG caused a decrease in GCLC and GCLM expression. Note a significant increase in the upregulation of both GCLC and GCLM expression by H2S.
