Further, HIF-1α/VEGF is an important signaling pathway in breast cancer angiogenesis [58], while VEGF has been suggested as a candidate biomarker for the basal-like breast cancer [59], but we found no association between HIF-1α/VEGF and various basal markers in this cohort, in contrast to some other studies on basal-like tumors [60–62], triple negative breast cancers [63] and breast cancer cell lines [64]. Here, VEGFA is linked to triple-negative breast carcinoma.
