Tead1 is required for perinatal cardiomyocyte proliferation.

ABSTRACT: Adult heart size is determined predominantly by the cardiomyocyte number and size. The cardiomyocyte number is determined primarily in the embryonic and perinatal period, as adult cardiomyocyte proliferation is restricted in comparison to that seen during the perinatal period. Recent evidence has implicated the mammalian Hippo kinase pathway as being critical in cardiomyocyte proliferation. Though the transcription factor, Tead1, is the canonical downstream transcriptional factor of the hippo kinase pathway in cardiomyocytes, the specific role of Tead1 in cardiomyocyte proliferation in the perinatal period has not been determined. Here, we report the generation of a cardiomyocyte specific perinatal deletion of Tead1, using Myh6-Cre deletor mice (Tead1-cKO). Perinatal Tead1 deletion was let
