Melatonin affects trophoblast epithelial-to-mesenchymal transition and oxidative damage resistance by modulating GDF15 expression to promote embryo implantation.

Melatonin is widely observed in the female reproductive system and regulates trophoblast cell functions, but its effects on embryo implantation and underlying mechanisms are not well understood. By constructing an in vitro embryo culture model, we found that melatonin enhances migration and implantation in human and mouse trophoblast cells. It also significantly promoted HTR-8/SVneo cell proliferation, inhibited apoptosis, enhanced migration, and mitigated oxidative damage.

Salinity changes the nitrification activity and community composition of comammox in intertidal sediments of Yangtze River estuary.

The newly discovered complete ammonia-oxidizing (comammox) has been identified in different environments, including coastal environments, where salinity is one of the most important factors for the abundance and activity of nitrifiers. Here, we demonstrate the effect of salinity on comammox , canonical ammonia-oxidizing bacteria (AOB), and ammonia-oxidizing archaea (AOA) in the intertidal sediments of the Yangtze River estuary based on microcosm experiments, DNA stable-isotope probing (DNA-SIP), and potential ammonium-oxidation rate (PAR) tests for different groups of ammonia oxidizers with selective inhibitors. During microcosm incubations, the abundance of comammox was more sensitive to increased salinity than that of other ammonia oxidizers.
