Jing Zheng, PhD, professor in the Division of Reproductive Sciences, recently published an article in the Journal of Physiology. Division of Reproductive Sciences trainees Ying-Jie Zhao, MD, PhD, and Chi Zhou, PhD, are co-first authors on the article. Sathish Kumar, PhD, is also co-author.
In “An endogenous aryl hydrocarbon receptor ligand induces preeclampsia-like phenotypes in rats”, the authors reveal that a tryptophan metabolite induced preeclampsia-like symptoms in pregnant rats. These symptoms are associated with fetal sex-specific disruption of gene expression and biological pathways in placentas. These suggest a novel mechanism underlying preeclampsia. Furthermore, these disrupted genes and pathways might represent therapeutic and fetal sex-specific targets for preeclampsia-induced impairment of vascular functions in placentas.

Congratulations to Jing Zheng, PhD, professor in the Division of Reproductive Sciences, whose recent article was selected as the Editor’s Choice in the August issue of The Journal of Physiology! Zheng is senior author on the article; Chi Zhou, PhD, former postdoctoral trainee in the Department of Ob-Gyn and current assistant professor at the University of Arizona, is the first author.
In “MicroRNA-29 differentially mediates preeclampsia-dysregulated cellular responses to cytokines in female and male fetal endothelial cells”, Zheng, Zhou and co-authors reveal fetal sex-specific dysregulation of target genes of two microRNAs in fetal endothelial cells from preeclampsia. This differential dysregulation may contribute to fetal sex-specific endothelial dysfunction in offspring born to preeclamptic mothers.
