(a) Cell viability of MCH58 fibroblasts cells cultured in glucose or galactose media with varying doses of meclizine for three days. Data are expressed as mean ± SD (n = 5).
(b) OCR in MCH58 fibroblasts cells cultured in glucose media with varying doses of meclizine for 200 min. Data are expressed as mean ± SD (n = 3). (*P<0.05; **P<0.005; two-sided t-test).
(c,d) OCR (c) and ECAR (d) in multiple cell types cultured in glucose media with 50 μM meclizine or DMSO for 200 min. Data are expressed as mean ± SD (n ≥ 3). (* P<0.05; two-sided t-test).
(e) Time course of meclizine (50 μM) mediated OCR reduction over DMSO baseline compared to other inhibitors of OXPHOS (1 μM each) in 293 cells. Data are expressed as mean ± SD (n ≥ 3).
(f) HIF-1α and HIF-2α detection by Western blot analysis of protein extract from HeLa cells after 6 hrs treatment with 0.1 % DMSO, 100 μM deferoxamine (DFO) or 50 μM meclizine. The complete immunoblot is provided as Supplementary Fig. 7b.
