Differentially expressed genes induced by TPA stimulation between the P2ry6+/+ and P2ry6-/- mice

ABSTRACT: We report that P2ry6-deficient mice exhibit marked resistance to 7,12-dimethylbenzanthracene (DMBA)/12-O-tetradecanoylphorbol-13-acetate (TPA)-induced two-stage skin papilloma formation compared with wild-type mice. Consistent with these findings, epidermal hyperplasia in response to TPA stimulation was suppressed in the P2ry6 knockout or MRS2578 (P2RY6 antagonist)-treated mice. The dramatic decrease in hyperplasia and tumorigenesis due to P2ry6 disruption was associated with the suppression of TPA-induced keratinocyte proliferation and inflammatory reactions.We have employed whole genome microarray expression profiling as a discovery platform to identify genes with the potential to distinguish differentially expressed genes induced by TPA stimulation between the P2ry6+/+ and P2ry6-/- mice. Notably, P2ry6 deletion prevented the TPA-induced increase in YAP nuclear accumulation and hence its downstream gene expression in an MST/LATS1-dependent manner.
