CD4 and cancer: We found that multiple RESs in CAVIN1 3’UTR were correlated with resting CD4+ memory T cells in at least six cancer types (Figure 3D), seven in IGAX 3’UTR (Figure 3E) with M2 macrophages in at least six cancer types, and one in VWA8 intron with M1 macrophages in six cancer types (Figure 3F).
