Project description:The hair follicle misorientation phenotype in Fzd6-/- mice appears to act through the PCP signaling system, but the downstream effectors of Fzd6 remain mysterious. We used microarrays to search for potential downstream effectors of the Fzd6 signaling pathway in regulating hair follicle orientation.
Project description:Analysis of skin lesions from adult mice with epidermal conditional deletion of heterotrimeric G protein Galpha s in cytokeratin 14 positive cells, compared with control mouse skin. Epidermal Gnas ablation leads to skin defects, including basal cell carcinoma (BCC). Results provide insight into role of Galpha s in the regulation of stem cells from the skin. Changes in gene expression following Gnas deletion from the mouse epidermis were analyzed. Skin from four independent mice of each wild type (control) and Gnas epidermal knockout (Gnas eKO) were analyzed.
Project description:This experiment used RNA-Seq technology to explore gene expression in mouse Insm1GFP.Cre/+ controls and Insm1 (Insm1GFP.Cre/GFP.Cre), Neurod1 (Insm1GFP.Cre/+; Neurod1LacZ/LacZ), or Pax6 (Insm1GFP.Cre/+; Pax6fl/fl) knockout FACS sorted pancreatic endocrine cells at E15.5. Comparison of Insm1GFP.Cre+/- and knockout animals revealed sets of differentially expressed genes that are required for endocrine cell specification and development.
Project description:Interventions: experimental group :PD-1 Knockout Engineered T Cells
Primary outcome(s): Number of participants with Adverse Events and/or Dose Limiting Toxicities as a Measure of Safety and tolerability of dose of PD-1 Knockout T cells using Common Terminology Criteria for Adverse Events (CTCAE v4.0) in patients
Study Design: historical control
Project description:This study aims to compared RNA expression profiles between the skin tissues of IRF1 knockout (IRF-/-) mice and wild-type mice by microarray analysis. Male IRF1 knockout (IRF-/-) mice and wild-type mice (8 weeks old) were irradiated with a single 35-Gy dose of irradiation was administered to the treatment area at a rate of 750 cGy/min using a 6-MeV electron beam accelerator (Clinac 2100EX, Varian Medical Systems, Inc., CA). Skin tissues from irradiated areas were collected and subjected to RNA expression analysis.
Project description:Analysis of changes in gene expression in skin epidermis upon conditional knockout of the essential Polycomb repressive complex 2 (PRC2) subunit Eed. Loss of Eed in skin epithelium leads to de-repression of key Merkel-differentiation genes, which are known PRC2 targets, and results in ectopic formation of Merkel cells that are associated with all hair types. Gene expression analysis: To determine the changes in gene expression in skin epidermis upon conditional knockout of Eed, total RNA was isolated from skin epidermis in four biologic replicates from cells in different conditions and hybridized to SurePrint G3 Mouse GE 8X60K microarrays (Agilent).
Project description:Dmrt1 (doublesex and mab-3 related transcription factor 1) is a conserved transcriptional regulator of male differentiation required for testicular development in vertebrates. This study examines the result of conditional removal of Dmrt1 in E15.5 ovaries.
