Satoshi Miyagami,Keiko Koide,Akihiko Sekizawa,Walter Ventura,Junko Yotsumoto,Shingo Oishi,Takashi Okai +6 more
TL;DR: During the early part of the first trimester of pregnancy, the placental gene expression levels of PlGF, HO-1, and SOD increase with gestational age, whereas the expression of FLT-1 decreases, and this pattern of gene expression in early pregnancy may play an important role in placenta-related disorders such as preeclampsia.
