In contrast, HIF1α and Jagged1 expression levels did not correlate significantly in any of the tumors (renal cancer; R2 = −0.031, p = 0.66; breast carcinoma, NOS, R2 = 0.062, p = 0.14; breast ductal cancer, R2 = 0.040, p = 0.47; breast cancer, others, R2 = 0.038, p = 0.90; neuroblastoma, R2 = 0.127, p = 0.16; medulloblastoma, R2 = 0.04, p = 0.73; Fig. 1k, Supplementary Figure 1E). Here, JAG1 is linked to renal carcinoma.
