Impaired ATP production and glycolysis in shGPR81 MDA-MB-231 cells. (a) ShNT and shGPR81 #1 cells were cultured for 24 h with or without 10 mM lactate and intracellular ATP concentrations were measured using an ATP assay kit (n = 3/group). **p < 0.01 using one-way analysis of variance followed by Tukey’s post hoc test. (b) Western blot analysis of glycolytic enzymes in shNT and shGPR81 #1 cells. Cell lysates from shNT and shGPR81 #1 cells were analyzed by immunoblotting using anti-HK2, anti-PFK1, anti-LDHA, and anti-β-actin antibodies.
