Elevated Serum Homocysteine Levels Impair Embryonic Neurodevelopment by Dysregulating the Heat Shock Proteins.

Observational studies have found that elevated serum homocysteine (Hcy) levels during pregnancy may be associated with the occurrence of neural tube defects (NTDs). However, the effect of Hcy on fetal neural development and its underlying molecular mechanisms remains unclear. To uncover the molecular mechanism, we analyzed the serum Hcy concentration in pregnant women with normal and abnormal pregnancy outcomes and treated zebrafish model embryos with high Hcy.

Changes in expression of FSH and LH receptors in the ovine main immune organs during early pregnancy.

Follicle-stimulating hormone (FSH) and luteinizing hormone (LH) are mainly involved in follicle development and ovulation, but FSH receptor (FSHR) and LH receptor (LHR) are also expressed in the immune system. Nevertheless, it is not clear if gestation affects the expression of the FSHR and LHR in the maternal main immune organs (thymus, lymph node, spleen, and liver). In this study, these organs were sampled from the ewes at the estrous cycle, and during early pregnancy, and mRNA and protein expression of FSHR and LHR were analyzed.
