Project description:Analysis of angiotensin II effect on left ventricle at gene expression level. The hypothesis tested in the present study was that angiotensin II treatment may affect gene expression in left ventricle in a strain specific manner. Results provide important information about which genes respond to angiotensin II in C57Bl/6N male mice compared to their C57Bl/6J counterparts. Total RNA obtained from isolated left ventricles from C57Bl/6J and C57Bl/6N mice subjected to 48 hours of angiotensin II infusion, via osmotic mini-pumps (500ng/kg/h) implanted sub-cutaneously, compared to sham operated controls.

Project description:The goals of this study is to identify the differential expressed genes in cardiac tissue of C57BL/6 mice with or without Angiotensin II (AngII) treatment, and compare the differential expressed genes in the cardiac tissue of Ang II infused C57BL/6 mice after Ethoxysanguinarine (ETH) treatment. Briefly, the mice (n=18) were randomly divided into 3 groups: control, AngII, AngII + ETH (n=6 for each group). Mice in Control and AngII groups were infused with saline and 500 ng/kg/min of AngII respectively, and orally administrated with saline; the mice in AngII + ETH group were infused with AngII (500 ng/kg/min) and orally administrated with 10 mg/kg /day of ETH daily for total 4 weeks. Then the cardiac tissue were used to identify differentially expressed genes among different groups.
Project description:We use next-generation sequencing (NGS) to profile miRNA in small arteries of mice infused with angiotensin (Ang) II for 7 and 14 days. The goal is to identify differentially expressed miRNAs that are associated with Ang II-induced vascular injury and hypertension.
Project description:We undertook a transcriptome-wide discovery approach to provide information on the involved gene regulatory responses to change in fetal cardiac mass in response to chronic infusion of angiotensin II or losartan. One of each of 8 twin fetus pairs was infused with either angiotensin II or losartan daily for five days in utero. A portion of the left ventricular free wall of treatment and control fetuses was excised, homogenized in a reagent, and then total RNA was then isolated and assayed on the agilent microarray

Project description:Bisphenol F (BPF) is a widely used substitute for bisphenol A (BPA) in plastic manufacturing; however, its potential toxicity remains insufficiently characterized. In this study, we investigated the impact of BPF exposure on the intestinal barrier and cardiovascular system. Based on prior untargeted metabolomic analysis, we revealed that BPF can be converted into N-acetylputrescine (NAP) through a microbiota-associated metabolic process. Further experiments demonstrated that BPF exposure stimulated intestinal epithelial cells to secrete spermidine/spermine N1-acetyltransferase 1 (Sat1), an enzyme involved in this conversion. To identify the cell types and signaling pathways associated with BPF exposure under hypertensive conditions, we conducted snRNA-seq of heart tissues from angiotensin II-infused mice and angiotensin II-infused mice pretreated with BPF exposure. The raw sequencing data and processed expression matrices are provided in this submission.
