Short communication: Upregulation of hypoxia/reoxygenation-induced Shc3 by downregulated miR-455-5p, suppresses trophoblast invasion and is associated with placental inflammation and angiogenesis in preeclampsia.

Preeclampsia is characterized by insufficient invasion of extravillous trophoblasts and is a consequence of failed adaption of extravillous trophoblasts to changes in the intrauterine environment developing embryo. Specific miRNAs are implicated in the development of preeclampsia (PE). miR-455-5p is present at low levels in PE but its role is not known.

Problem: Hashimoto's disease is the commonest autoimmune disease of pregnancy. The presence of Anti-Thyroid antibodies (ATAs) alone [subclinical hypothyroidism] has also been shown to have adverse pregnancy effects. These can result in failure to conceive, recurrent miscarriages, anemia, preeclampsia, and abruption.

Pregnancy complications pose challenges for both pregnant women and obstetricians globally, with the pathogenesis of many remaining poorly understood. Recently coined as a mode of cell death, cuproptosis has been proposed but remains largely unexplored. This process involves copper overload, resulting in the accumulation of fatty acylated proteins and subsequent loss of iron-sulfur cluster proteins.

Intrauterine growth restriction (IUGR) is the second most common obstetric complication after preterm labor. Appropriate trophoblast differentiation and placental structure, growth and function are key for the maintenance of pregnancy and normal fetal growth, development and survival. Extravillous trophoblast cell proliferation, migration and invasion are regulated by molecules produced by the fetomaternal interface, including autocrine factors produced by the trophoblast, such as insulin‑like growth factor (IGF)‑1.

School of Medicine, The International Peace Maternity and Child Health Hospital, Shanghai Jiao Tong University, Shanghai, 200030, China.
Background: Intrahepatic cholestasis of pregnancy (ICP) is the most common liver disorder associated with pregnancy and is usually diagnosed based on high serum bile acid. However, the pathogenesis of ICP is unclear. Ferroptosis has been reported as an iron-dependent mechanism of cell death.
