Furthermore, quantitative analysis of the RNA levels indicated a reduction of VEGFA (the isoform mainly involved in tumour angiogenesis; Claesson‐Welsh & Welsh, 2013) in ERO1 KO cells under hypoxic conditions (Varone et al., 2021) (Figure 2a), but not that of VEGFB (Figure S2). The gene discussed is VEGFA; the disease is neoplasm.
