Expression of HK II, PFK1, PKM2, LDHA and GLUT1 in cervical biopsies was detected by Western blot analysis. In total, 32 biopsies were examined, including normal cervical tissues (samples 1, 2, 3, 14, 15, 16, 17, 23, 24), LSIL (samples 4, 5, 6, 18, 19, 25, 26), HSIL (samples 7, 8, 9, 10, 20, 27, 28, 29) and SCC (samples 11, 12, 13, 21, 22, 30, 31, 32) (A). The relative expression of HK II, PFK1, PKM2, LDHA and GLUT1 was normalized by β-actin (B). *P < 0.05, **P < 0.01.
