Research summary

This study explores how YAP/TAZ-TEAD signaling regulates endothelial cell metabolism and angiogenesis. Endothelial-specific deletion of YAP/TAZ reduced nutrient transporter expression and mTORC1 activity, impairing proliferation. A constitutively active TAZ mutant (TAZ^S89A), expressed from the Rosa26 locus, restored angiogenic capacity.

Key outcome of the study

YAP/TAZ-TEAD promotes endothelial nutrient uptake and mTORC1 signaling, driving angiogenesis; disruption impairs vascular growth, highlighting a therapeutic axis.

Model

Rosa26 Knockin mouse expressing constitutively active TAZ^S89A under endothelial-specific Cre control, using IRES technology for bicistronic expression of a reporter.

TARGET:
YAP1, WWTR1, TEAD1-4, SLC7A5
Yes-associated protein 1 (YAP1), WW domain-containing transcription regulator 1 (TAZ), TEADs, Solute carrier family 7 member 5
