Abstract:
To investigate the inhibitory effect of wogonin on glucose metabolism in human gastric carcinoma MGC-803 cells and its underlying mechanism, Amplex Red Glucose/Glucose Oxidase Assay Kit was used to explore the influence of wogonin on glucose uptake of MGC-803 cells and lactate assay kit was adopted to evaluate the lactate generation of MGC-803 cells. Annexin V/PI staining assay was performed to observe the apoptotic rate of MGC-803 cells. Changes in the expression of hexokinase 2(HK II), glucose transporter 1(GLUT1), pyruvate dehydrogenase kinase(PDHK)and lactate dehydrogenase A(LDH-A)were assessed by Western blot. These results demonstrated that wogonin significantly reduced glucose uptake of MGC-803 cells at certain concentration. Meanwhile, wogonin apparently reduced the lactate generation of MGC-803 cells, without inducing notable cell apoptosis. Besides, with the impact of wogonin, the expression of glucose metabolism related proteins declined obviously. In a word, wogonin could inhibit the glucose metabolism of MGC-803 cells without inducing apparent apoptosis, which may be related to its inhibitory influence on the proteins in glucose metabolism of MGC-803 cells.
