PPP6C and psoriasis: In an IL-23-mediated mouse model of psoriasis, the ppp6c expression was increased more than ∼8.0-fold at the mRNA levels and 12.0-fold at the protein levels in the ear epidermis of the cKO mice injected with IL-23 compared with that of the miR-31fl/fl controls (Supplementary Fig. 10a,b).
