RT-PCR analysis of the mRNA levels of HIF-1α (a), Notch receptors (b-e), and HES1 (f) in tissues with different MCs. Spearman’s rank correlation analysis was performed to analyze the correlation between HIF-1α and Notch1 (g), HIF-1α and Notch2 (h), HIF-1α and Notch3 (i), and HIF-1α and Notch4 (j). Values are presented as the mean ± S.E.M. *p < 0.05, **p < 0.01
