Project description:Menopause is associated with an increase in the prevalence and severity of hypertension in women. Although premenopausal females are protected against T cell-dependent immune activation and development of angiotensin II (Ang II) hypertension, this protection is lost in postmenopausal females. Therefore, the current study hypothesized that specific CD4+ T cell pathways are regulated by sex hormones and Ang II to mediate progression from premenopausal protection to postmenopausal hypertension. Menopause was induced in C57BL/6 mice via repeated 4-vinylcyclohexene diepoxide (VCD) injections, while premenopausal females received sesame oil vehicle. A subset of premenopausal mice and all menopausal mice were infused with Ang II for 14 days (Control, Ang II, Meno/Ang II). Proteomic and phosphoproteomic profiles of CD4+ T cells isolated from spleens were examined.Ang II markedly increased CD4+ T cell protein abundance and phosphorylation associated with DNA and histone methylation in both premenopausal and postmenopausal females. Compared to premenopausal T cells, Ang II infusion in menopausal mice increased T cell phosphorylation of MP2K2, an upstream regulator of ERK, and was associated with upregulated phosphorylation at ERK targeted sites. Additionally, Ang II infusion in menopausal mice decreased T cell phosphorylation of TLN1, a key regulator of IL-2R and FOXP3 expression. These findings identify novel, distinct intracellular T cell pathways that influence T cell-mediated inflammation during postmenopausal hypertension.

Project description:Mammalian females are born with a finite number of non-renewing primordial follicles, the majority of which remain in a quiescent state for many years. Due to their non-renewing nature, these “resting” oocytes are particularly vulnerable to xenobiotic insult, resulting in premature ovarian senescence and the formation of dysfunctional oocytes. In this study we characterised the mechanisms of ovotoxicity for three ovotoxic agents, 4-Vinylcyclohexene Diepoxide (VCD), Methoxychlor (MXC), and Menadione (MEN), all of which target immature follicles. Neonatal mouse ovaries (PND3-4) were cultured in the presence of 4-Vinylcyclohexene Diepoxide (50uM), Methoxychlor (50uM), and Menadione (5uM) for 96 hours to observe their effects on the ovarian transcriptome. This was done in the hopes of gaining a better understanding of the mechanisms underpinning xenobiotic induced pre-antral ovotoxicity.

Project description:Mammary gland is a dynamic organ which undergoes most of its structural development after birth under cyclic control of ovarian hormones such as estrogen and progesterone. Using 4-vinylcyclohexene diepoxide (VCD) menopause model, we investigated the effect of ovarian hormones on mouse mammary glands. In particular, we focused on mouse mammary gland fibroblasts because they are one of the known crucial players but yet to be characterized well. With integrated analysis including six other publicly available datasets as well as mammary epithelium atlas data, we comprehensively described the characters of mouse mammary gland (e.g. potential commitment to mammary gland development, response to estrogens, developmental relationship, and crosstalk with mammary epithelium) in a population specific manner. Furthermore, we investigated the effect of endocrine disrupting chemical named polybrominated diphenyl ethers (PBDEs) in either of absence or presence of ovarian hormones on whole cellular components of mouse mammary gland including epithelial cells, fibroblasts, and immune cells at a single cell level.

Project description:Background: Pre-diabetes condition precedes the Diabetes Mellitus (DM) disease and is a critical period for hyperglycemia treatment, especially for menopausal women, considering all metabolic alterations due to hormonal changes. Recently, the literature has demonstrated the role of physical exercise in epigenetic reprogramming to modulate the gene expression patterns of metabolic conditions, such as hyperglycemia, preventing DM development. In the present study, we hypothesized that physical exercise training could modify the epigenetic patterns of women with poor glycemic control. Methods: 48 post-menopause women aged 60.3±4.5 years were divided according to the fasting blood glucose levels into two groups: Prediabetes Group, PG (n=24) and Normal Glucose Group, NGG (n=24). All participants performed 14 weeks of physical exercise three times a week. The Infinium Methylation EPIC BeadChip measured the participants’ Different Methylated Regions (DMRs). Results: Before the intervention, the PG group had 12 DMRs compared to NGG. After the intervention, five DMRs remained different. Interestingly, when comparing the PG group before and after training, 118 DMRs were found. The enrichment analysis revealed that the genes were related to different biological functions such as energy metabolism, cell differentiation, and tumor suppression. Conclusion: Physical exercise is a relevant alternative in treating hyperglycemia and preventing DM in post-menopause women with poor glycemic control.

Project description:Osteoporosis is a multifactorial disease with genetic and strong epigenetic component. In spite of enormous candidate gene association studies, the etiology and molecular mechanism of disease is not fully known. This study is undertaken to identify new markers of osteoporosis which could be vital in diagnosis and prognosis of disease, genome-wide microarray expression approach was employed on post menopausal Indian females living in same geographical area with almost similar life-style. To validate microarray gene expression pattern, qRT-PCR was performed on top 5 genes on osteoporotic (n =32) and non-osteoporotic (n=15) post menopausal females
