Correlations between evening HIF-1α protein level and circadian proteins (PER1, CRY1, and CLOCK). (A) Correlation between evening hypoxia-inducible factor (HIF) 1α protein level and evening period 1 (PER1) protein level (R = 0.618, p = 0.004). (B) Correlation between evening hypoxia-inducible factor (HIF) 1α protein level and evening cryptochrome 1 (CRY1) protein level (R = 0.514, p = 0.020). (C) Correlation between evening hypoxia-inducible factor (HIF) 1α protein level and evening Circadian Locomoter Output Cycles Protein Kaput (CLOCK) protein level (R = 0.618, p = 0.004).
