Other genes with significantly higher expression in HT samples included inflammatory cytokines, such as TNF and IL1B, as well as growth factors VEGFA and TGFB1. DEGs with lower expression in HT samples included several involved in Wnt signalling, such as WNT2, WNT4 and SFRP2, along with the growth factor receptors EGFR, FGFR2 and TGFBR2. The full list of DEGs is available in Table S3. Here, WNT4 is linked to hematocrit.
