Distinct functions of photoreceptor cell-specific nuclear receptor, thyroid hormone receptor beta2 and CRX in one photoreceptor development.

Abstract

The results indicate that PNR may suppress proliferation of cone photoreceptor progenitor cells and that the regulation of S- and M-cone opsin gene expression is mediated by TRbeta2 and CRX, but not by PNR. Thus, our results partly disclosed the molecular mechanism of cone photoreceptor development, highlighting the distinct functions of PNR and TRbeta2.
