Developmental Programming: adipose depot-specific regulation of non-coding RNAs and their relation to coding RNA expression in prenatal testosterone and prenatal bisphenol-A -treated female sheep

Project description:Inappropriate developmental exposure to steroids is linked to metabolic disorders. Prenatal testosterone excess or bisphenol A (BPA, an environmental estrogen mimic) leads to insulin resistance and adipocyte disruptions in female sheep. Adipocytes are key regulators of insulin sensitivity and tissue-specific differences in insulin sensitivity, coupled with adipose depot-specific changes in key mRNAs, were previously observed. We hypothesized that depot-specific changes in the non-coding RNA (ncRNA) regulators of gene expression would prevail to account for the direction of changes seen in mRNAs. Noncoding RNA (lncRNA, miRNA, snoRNA, snRNA) from various adipose depots of prenatal testosterone and BPA-treated animals were sequenced. Adipose depot-specific changes in the ncRNA that are consistent with the depot-specific mRNA expression in terms of directionality of changes and functional implications in insulin resistance, adipocyte differentiation and cardiac hypertrophy were found. Importantly, the adipose depot-specific ncRNA changes were model-specific that were mutually exclusive suggestive of different regulatory entry points in this regulation.

Developmental Programming: Adipose Depot-Specific Transcriptional Regulation by Prenatal Testosterone Excess in a Sheep Model of PCOS

Project description:This study seeks to undertake an assessment of the effects of prenatal exposure of female sheep to excess testosterone, the estrogen precursor, in four different adipose depots. The depots investigated are subcutaneous adipose tissue (SAT) - a fat beneath the skin storing >80% of total body fat in the human body, visceral adipose tissue (VAT) - an intra-abdominal fat primarily associated with digestive system organs, and smaller depots such as epicardial adipose tissue (ECAT) and perirenal adipose tissue (PRAT) that serve specialized functions associated with the organs/tissues in their proximity. The goals are to 1) determine gene expression and gene network profiles in the depots; 2) assess prenatal T-treatment induced disruptions in adipose depot-specific gene expression and gene networks; and 3) identify common and divergent gene and gene pathways underlying depot-specific disruption in prenatal T-treated female sheep.

Developmental Programming: Differing impact of prenatal testosterone and prenatal bisphenol-A -treatment on hepatic methylome in female sheep

Project description:Steroid hormones play a crucial role in pregnancy and fetal development, influencing metabolism, inflammation, and immune responses. Excessive prenatal exposure to steroids or environmental chemicals like bisphenol A can disrupt offspring's metabolism. This study examines how prenatal exposure to testosterone and BPA affects the liver's DNA methylome, which is critical for long-term health.

Developmental Programming: Impact of prenatal testosterone excess on liver and muscle transcriptome and the relationship between non-coding and coding RNA networks in female sheep [ncRNA-seq]

Project description:This study seeks to assess the effects of prenatal exposure of female sheep to execessive testosterone in metabolically relevant liver and muscle tissue. The goals are to 1) determine noncoding RNA in the control animals and 2) assess the effects of prenatal T-treatment on non-coding RNA. 3) Finally identify putative ncRNA-totalRNA interactions.

Developmental Programming: Sheep Granulosa and Theca Cell-Specific Transcriptional Regulation by Prenatal Testosterone

Project description:Prenatal testosterone treated sheep, similar to PCOS women, manifest reduced cyclicity, functional hyperandrogenism and polycystic ovary (PCO) morphology. The PCO morphology results from increased follicular recruitment and persistence of antral follicles, consequence of reduced follicular growth and atresia, and driven by cell-specific gene expression changes that are poorly understood. Therefore, utilizing RNA sequencing, cell-specific transcriptional changes were assessed in laser capture microdissection isolated antral follicular granulosa and theca cells from 21 months-of- age control and prenatal testosterone treated sheep.
