YAP knockdown in HUVEC elicits proliferation and cell cycle preogression defects. YAP deficient cells caused arrest in G1 and defects in S-phase entry. The microarray analysis was conducted to identify potential YAP targets that are involved in HUVEC cell cycle regulation
YAP regulates S-phase entry in endothelial cells.

View SamplesThe Hippo pathway directs cell differentiation during organogenesis, in part by restricting proliferation. How Hippo signaling maintains a proliferation-differentiation balance in developing tissues and its underlying molecular targets are poorly understood. Our study shows that Hippo suppresses NF?B signaling in pancreatic progenitors to permit cell differentiation and developmental progression. We found that pancreas-specific Lats1/2 kinase deletion (Lats1/2PanKO) from mouse progenitor epithelia results in failure to differentiate 3 key pancreatic lineages: acinar, ductal, and endocrine. We performed an unbiased transcriptome analysis to query the differentiation defects in Lats1/2PanKO. This analysis revealed increased NF?B activator expression, including the pantetheinase Vanin1 (Vnn1). Through in vivo and ex vivo studies, we show that VNN1 activates a detrimental cascade of processes in Lats1/2PanKO epithelium, whereby 1) NF?B activation and 2) initiation of epithelial-to-mesenchymal transition (EMT) together override normal differentiation. We show that exogenous stimulation of VNN1 or NF?B can also trigger this cascade in WT pancreatic progenitors. These findings show that pancreas development requires active suppression of NF?B by LATS1/2 kinases to restrain a cell-autonomous transcriptional program and thereby allow for differentiation. Overall design: RNA-Seq comparing total RNA from 5 WT samples and 3 Lats1/2-deficient pancreas samples at E11.0.
LATS1/2 suppress NFκB and aberrant EMT initiation to permit pancreatic progenitor differentiation.

Hippo pathway activity influences liver cell fate.
Specimen part, Time
View SamplesHippo signaling is highly associated with activity in the stem cell compartment of many epithelial tissues. In this study, we examined if Hippo signaling inhibition (by inducing Yap expression) could convert differentiated cells into a progenitor like phenotype. Organoid cells derived from mouse livers under various conditions, wild-type, Yap ON (Plus Dox), and Yap ON then OFF (Minus Dox) was examined.
