High impact information on PDGFRA

  • The role played by PDGF receptor alpha (PDGF-Ralpha) was investigated by selective stimulation with PDGF-AA, by blocking PDGF-BB-binding to PDGF-Ralpha with neomycin, or by transfecting cells with dominant-negative forms of the receptors to selectively impair either PDGF-Ralpha or PDGF-Rbeta function [1].
  • In contrast, the PDGF receptor did not recognize progesterone receptor as a substrate [2].
  • Treatment of organ cultures with the selective PDGF receptor signalling inhibitor, AG1296 (tyrphostin), blocked or impaired mesonephric cell migration in both the mammalian and avian systems [3].
  • We found that PDGF-A and PDGF receptor-alpha are both up-regulated male-specifically in embryonic chicken and mouse gonads [3].
  • In the present study we measured the level of PDGF receptor expression by chicken myoblasts and the effect of the three different PDGF isoforms (AA, AB, BB) on DNA synthesis by myoblasts [4].

Biological context of PDGFRA

  • Furthermore, since we have previously shown that fetal myoblasts are replaced with adult myoblasts during late chicken embryogenesis, we compared PDGF receptor expression and function on myoblasts from Embryonic Day 10 (E10, mid development) and from Embryonic Day 19 (E19, late development) [4].

Anatomical context of PDGFRA

  • Platelet-derived growth factor receptor alpha (PDGFR-alpha) is present throughout the mesenchyme of early chick limb buds, while its ligand, PDGF-A, is expressed in the surrounding epithelium [5].
  • PDGF receptor binding analysis indicated that beta-receptors were predominant receptors present on the chondrogenic and nonchondrogenic cells of the stage 24 mesoderm [6].
  • We examined PDGF receptor expression and function on clonally derived myoblasts in order to eliminate contaminating fibroblasts which are present in myogenic cultures and which bind PDGF [4].
  • These Nkx-2.2+ cells are specifically labeled by the early oligodendrocyte markers PDGFR alpha, O4 and GalC, but not the microglial marker QH1 or neuron-specific marker MAP-2 [7].
  • In cholesterol-fed roosters, intense immunohistochemical reaction for PDGF-B, PDGF receptor, and c-myc was seen in the lipid-rich thickened intimal lesions of the thoracic and abdominal aortas while no significant immunoreaction for PDGF-A was demonstrated in the same lesions [8].
