Project description:Analysis of LBNF1 rat testes from controls, containing both somatic and all germ cell types and from irradiated rats in which all cells germ cells except type A spermatgogonia are eliminated. Results provide insight into distinguishing germ and somatic cell genes and identification of somatic cell genes that are upregulated after irradiation.

Project description:This is a study to explore the transcriptional changes after Adjudin treatment in adult rat testes at three time points (control, 8 hour and 4 day). Adjudin, [1-(2,4-dichlorobenzyl)-1H-indazole-3-carbohydrazide], is a potential male contraceptive that targets the Sertoli-germ cell interface and causes germ cell depletion from the seminiferous epithelium. Adjudin has been proved to be a useful model to study the mechanisms that regulate junction restructuring in the testis. Experiment Overall Design: Sprague-Dawley rats treated with a single dose of Adjudin at 50 mg/kg b.w. by gavage and terminated after 8 hours (n=2) and 4 days (n=3). Testes from Adjudin-treated rats and untreated (control, n=3) rats were harvested and total RNA were prepared. Standard Affymetrix genechip procedures were followed for the subsequent experiments. Data were analysed in MAS 5.0 and GeneSpring 7.2.

Project description:Analysis of hormone effects on irradiated LBNF1 rat testes, which contain only somatic cells except for a few type A spermatgogonia. Rats were treated for 2 weeks with either sham treatment (group X), hormonal ablation (GnRH antagonist and the androgen receptor antagonist flutamide, group XAF), testosterone supplementation (GnRH antagonist and testosterone, group XAT), and FSH supplementation ((GnRH antagonist, androgen receptor antagonist, and FSH, group XAFF). Results provide insight into identifying genes in the somatic testis cells regulated by testosterone, LH, or FSH.

Project description:Knee osteoarthritis (KOA), as a degenerative multifactorial disease, affects the quality of life and mental health of patients, and also brings a huge socioeconomic burden. Treating synovitis have shown promise as anti-inflammatory therapeutics in mitigating OA symptoms and disease progression. Here, by analysing synovial single-cell sequencing (scRNA-seq) data from KOA, we found that synovial fibroblasts (FLS) in OA synovium showed a distinct pro-inflammatory phenotype. We collected synovial tissue from patients with clinical OA as well as from healthy donors, and histological examination was consistent with findings in scRNA-seq. Inspired by recent cross-tissue fibroblast lineage studies, we identified by sequencing that healthy FLS in synovial tissues share transcriptome-level similarities with dermal fibroblasts (DFb). Subsequently, we revealed the local as well as systemic distribution of intra-articular injected DFbs by constructing/extracting two types of rat fibroblasts (luciferase DFbs as well as GFP DFbs). The results demonstrate that DFbs can be locally retained in the synovium for up to three weeks following targeted engrafting on it. And intra-articular injection does not result in DFbs migration to vital organs or the occurrence of histological changes in these organs. A rat model of KOA was constructed by anterior cruciate ligament transection (ACLT) in order to study the therapeutic effect of DFbs on KOA. After injection, the rats showed improvement in painful gait. In addition, histological as well as imaging results showed reduced synovitis and improvement in articular cartilage. Finally we verified the protective effect of DFbs on cytokine-stimulated chondrocytes in a co-culture system.

Project description:This is a study to explore the transcriptional changes after cadmium treatment in adult rat testes at three time points (control--0 hour, 8 hour and 4 day). Cadmium is an environmental toxicant that is known to affect the male reproductive system. It disrupts the blood-testis barrier irreversibly, and affects the Sertoli-germ cells adhesion, causing germ cell depletion from the seminiferous epithelium. Keywords: Cadmium effect in rat testes
