(A) Representative high-resolution ¹H MR spectra obtained from the aqueous phase of 231-EV, sh-HIF-1α, sh-HIF-2α shRNA and sh-HIF-1/2α tumors. GPC: glycerophosphocholine, PCholine: phosphocholine, BCA: branched chain amino acids. (B) Representative high-resolution ¹H MR spectra obtained from the lipid phase of 231-EV, sh-HIF-1α, sh-HIF-2α and sh-HIF-1/2α tumors. All spectra were plotted on the same vertical scale and acquired with identical experimental parameters. PtdEA: phosphatidylethanolamine, PtdCholine: phosphatidylcholine.
