Physiological Oxygen Concentrations Reveal a Pro-glycolytic Metabolism in the Absence of p62
(A) Representative western blot analysis of Hif-1α and p62 steady-state levels in Co1NES and Pat1NES cells, cultured for 0, 8, or 24 h at 3% O2. Tubulin was used as a loading control (n = 3).
(B) Quantification of (A). Data are expressed as mean ± SD and differences were tested by a two-tailed t test. ∗∗p < 0.01, ∗∗∗p < 0.001, n = 3.
(C) Western blot analysis of HK2, PDK1, PDK3, and LDHA as in (A). Tubulin was used as a loading control. n = 3.
(D) Western blot analysis of Hif-1α expression in Co1NES and Pat1NES cells, cultured for 0, 5, or 24 h in the presence of 200 μM CoCl2. Tubulin was used as loading control. n = 5.
