Yes-associated protein is involved in proliferation and differentiation during postnatal liver development.

ABSTRACT: It is known that the liver undergoes size increase and differentiation simultaneously during the postnatal period. Cells in the liver undergo a period of well-controlled proliferation to achieve the adult liver-to-body weight ratio. The postnatal liver growth is also accompanied by simultaneous hepatic differentiation. However, the mechanisms of liver size regulation and differentiation are not completely clear. Herein we report that yes-associated protein (Yap), the downstream effector of the Hippo Kinase signaling pathway, plays a role in liver size regulation and differentiation during the postnatal liver growth period. Postnatal liver growth was studied in C57BL/6 mice over a time course of postnatal days (PND) 0-30. Analysis of nuclear Yap by Western blot indicated peak Yap activation
