Project description:The purpose of the present study is to determine the effect of Percutaneous Collagen Induction (PCI) on the epidermis and dermis, including the systemic inflammatory response on gene expression level using microarray analysis. PCI Therapy is an alternative for safely treating wrinkles and scars and smoothening the skin. Therefore animal experiments were performed using 31 male Sprague-Dawley rats (350–375 g), age 4 month, randomly assigned into three groups: group (A) (n=24: needling plus skin care), group (B) (n=6: skincare only, controls after 24 h) and group (C) (n=1: negative control). Rats were anesthetized, shaved, and received a 30% total body surface area (TBSA) scald needling (10min) to induce percutaneous collagen, using a medical needling instrument (Environ® Medical Roll-CITTM, Vivida SA cc, Cape Town, South Africa). After needling surgery, the rats were immediately prepared with high levels of vitamin A cream and vitamin C cream, applied topically after cleaning once per day. The control group (C) rats received no injury, no skin care, no treatment, no anesthesia, and no analgesia. Gene expression analyses were performed 1 h, 24 h, 2, 4, and 8 weeks after PCI surgery. To confirm RNA expression in rat skin, self developed microarrays including genes like cytokines, such as vascular endothelial growth factor (VEGF), fibroblast growth factor (FGF 2), keratinocyte growth factor (KGF), epidermal growth factor (EGF), and transforming growth factors (TGF ß1, ß2, ß3) were used.
Project description:In order to establish a rat embryonic stem cell transcriptome, mRNA from rESC cell line DAc8, the first male germline competent rat ESC line to be described and the first to be used to generate a knockout rat model was characterized using RNA sequencing (RNA-seq) analysis.
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:Contrast-induced acute kidney injury (CI-AKI) is a serious complication of percutaneous coronary intervention (PCI). Emerging evidence suggests that messengerRNAs (mRNAs) and long non-coding RNAs (lncRNAs) could serve as biomarkers for various diseases.
