Summary of CIITA RT-qPCR results. Relative increase in CIITA mRNA expression following IFNy stimulation, mean cycle threshold (Ct) values for CIITA expression pre- and post-stimulation as determined by RT-qPCR. Each condition performed with four technical replicates. Relative expression calculated using 2^-(ΔΔCt) method and controlled using GAPDH.

Cancer cell expression of MHC class II significantly impacts tumor microenvironmental immunity. Previous studies investigating mechanisms of repression of IFNγ-inducible class II expression using cell lines demonstrate epigenetic silencing of IFN pathway genes as a frequent immune evasion strategy. Unlike cell lines, patient-derived organoids maintain epigenetic fidelity to tissue of origin. In the first such study, we analyze patterns, dynamics, and epigenetic control of IFNγ-induced class II expression in a series of colorectal cancer organoids.
