High impact information on Tcfeb

  • Mutational studies in mice have shown that Mitf is essential for melanocyte and eye development, whereas Tfeb is required for placental vascularization [1].
  • The expression of several trophoblast markers was also altered, including an increase in the spongiotrophoblast marker Mash2 and decreases in the labyrinthine markers Tfeb and Gcm1 [2].
  • Our results indicate that Tfeb plays a critical role in the signal transduction processes required for normal vascularization of the placenta [3].
  • Here we show that mice with a targeted disruption of Tfeb die between 9.5 and 10.5 days in embryonic development and have severe defects in placental vascularization [3].
 

Anatomical context of Tcfeb

  • Tfeb is expressed at low levels in the embryo but at high levels in the labyrinthine trophoblast cells of the placenta [3].
