Disease relevance of Pgf

  • Chronic hypoxia significantly decreases the circulating levels of PlGF (P < .001) independent of L-NAME treatment [1].
  • Conclusions: Intramyocardial delivery of PlGF following a large myocardial infarction enhanced border zone angiogenesis, attenuated adverse ventricular remodeling, and preserved cardiac function [2].
 

High impact information on Pgf

  • In contrast, pure PlGF homodimers are mitogenic for endothelial cells only at high, possibly non-physiologic concentrations; thus the biological relevance of their mitogenic activity for these cells is not obvious [3].
  • Methods: Wistar rats underwent high proximal ligation of the left anterior descending coronary artery and direct injection of PlGF (n = 10) or saline as a control (n = 10) into the myocardium bordering the ischemic area [2].
  • Using in situ hybridization histochemistry, positive cells of PlGF mRNA were detected in chorionic villi [4].
  • RT-PCR analysis showed that the expression level of PlGF mRNA increased as gestation advanced [4].
  • The expression pattern of PlGF mRNA in rat placenta during pregnancy demonstrates that PlGF plays a functional role for placental growth and fetal development during mid-late pregnancy [4].
 

Biological context of Pgf

  • CONCLUSION: Chronic NO inhibition as well as hypoxia induce fetal growth restriction and significantly change maternal circulating levels of sFlt-1 and PlGF, but not of VEGF [1].
  • In particular, the density and number of positive signals of PlGF mRNA was significantly increased as gestation advanced [4].
