Astrocyte pVHL and HIF-α Isoforms Are Required for Embryonic-To-Adult Vascular Transition In The Eye

This paper from Toshihide Kurihara, Peter Westenskow, Tim Krohne, Edith Aguilar, Randy A. Johnson, and Marty Friedlander propose a model for the transition from embryonic to adult circulation in the eye  using a combinatorial gene deletion approach with over expression assays, examining astrocyte-targeted deletion of von Hippel-Lindau tumor suppressor (Vhl), hypoxia-inducible factor-αs (Hif-αs), and VEGF on normal regression of hyaloid vessels which are transient fetal vessels in the eye that can be seen in the second and early third trimester of human pregnancy.  Continue reading “Astrocyte pVHL and HIF-α Isoforms Are Required for Embryonic-To-Adult Vascular Transition In The Eye”
