Furthermore, an inorganic source of H2S (NaSH) was shown to enhance glucose uptake and glycolysis efficiency in cardiomyocytes [156] likely both by stimulating the activity of glucose transporter and of glyceraldehyde 3-phosphate dehydrogenase (GAPDH) [157,158], a finding that was further reported in a panel of cancer cell lines [159]. Here, GAPDH is linked to cancer.
