(A-B) Ctrl or YY1iKO ASCs were treated with CHX (Cycloheximide) for 90 mins and Hif1α protein was measured by flow cytometry. The numbers indicate the degradation rate after CHX treatment. N=3 mice. (C) The relative degradation rate was calculated by the ratio of degradation rate in YY1iKO (11.14% ± 1.71%) vs Ctrl (5.08% ± 0.796%). N=3 mice.
