Project description:Cellular basis of sex-role reversal: male pregnancy in seahorses
Project description:Maternal infection and inflammation during pregnancy is associated with neurodevelopmental disorders in offspring, but little is understood about the molecular mechanisms underlying this epidemiologic phenomenon. We leveraged single-cell RNA sequencing to profile transcriptional changes in the rodent fetal brain in response to maternal immune activation (MIA) and identified perturbations in cellular pathways associated with mRNA translation, ribosome biogenesis, and stress signaling. We found that MIA specifically activated the integrated stress response (ISR) in male, but not female, MIA offspring, thereby reducing global mRNA translation and altering nascent proteome synthesis. Moreover, genetic blockade of ISR activation rescued the social behavior phenotype in MIA male offspring. Our data suggest that therapeutic targeting of the ISR may be beneficial in reducing maternal inflammation-associated neurodevelopmental disorders.
Project description:Supporting healthy pregnancy outcomes requires a comprehensive understanding of the cellular hierarchy and underlying molecular mechanisms during peri-implantation development. Here, we presented a single-cell transcriptome-wide view of the bovine peri-implantation embryo development at day 12, 14, 16 and 18, when most of the pregnancy failure occurs. We defined the development and dynamic progression of cellular composition and gene expression of embryonic disc, hypoblast, and trophoblast lineages during bovine peri-implantation development. Notably, the comprehensive transcriptomic mapping of trophoblast development revealed a previous unrecognized primitive trophoblast cell lineage that are responsible for pregnancy maintenance in bovine prior to the time when binucleate cell emerges. We analyzed novel markers for the cell lineage development during bovine early development. We also identified cell-cell communication signaling underling embryonic and extraembryonic cells interact to ensure proper early development in bovine. Collectively, our work provides foundational information to discover essential biological pathways underpinning bovine peri-implantation development and the molecular causes of the early pregnancy failure during this critical period.

Project description:In this study, we investigated the molecular and cellular mechanisms of verapamil treatment on β-cell function and survival using MIN6 cells. Verapamil's molecular processes were studied using transcriptomic data. MTT, cell count, and flow cytometry assessed cell proliferation, growth, and cycle. MIN6 cell function was assessed by glucose-stimulated insulin release and total insulin content. Seahorse and metabolic stress kits examined metabolic activity and oxygen consumption rate. The protective impact of verapamil on MIN6 cells was evaluated by challenging the verapamil treated cell with streptozotocin, T1D-cytomix, or T2D-cytomix cocktail. Our results demonstrate that verapamil treatment induced higher proliferation of MIN6 cells, altered expression of various proteins and genes, improved insulin secretion in hyperglycemic conditions, increased basal and maximal respiration levels, along with β-cell survival against streptozotocin, T1D-, or T2D-cytomix-induced toxicity, and rendered a protective effect.
