SLC2A1 and lactic acidosis: MRC-5 cells cultured under lactic acidosis and normoxia or hypoxia diminished their growth rate, the expression of GLUT1, MCT1 and MCT4, the transcript levels of AMPK and CS, as well as the protein levels of AMPK and HIF-1α in comparison with neutral lactosis, though only under normoxia the differences were significant.
