As seen with XBP1ΔDC mice, tumor cDC1s from XBP1ΔcDC1 mice also showed signs of RIDD, as indicated by an increase in XBP1s splicing ratio (Supplementary Figure 8G) and loss of CD11c surface expression (Supplementary Figure 8H), albeit to a lower extent than observed with Itgax-Cre mice line (Supplementary Figure 6G). This evidence concerns the gene ITGAX and neoplasm.
