Project description:Two patients with alopecia areata were treated with systemic ruxolitinib. Skin biopsies were taken before starting treatment and 12 weeks after starting treatment. We used microarrays to assess changes in gene expression of affected skin before and after starting treatment Two patients with alopecia areata were recruited for our study. Skin biopsies of affected scalp were taken prior to starting treatment with oral ruxolinitib. Additional skin biopsies were taken 12 weeks after starting treatment. Scalp skin biopsies were taken from patients without alopecia areata for comparison. RNA was extracted, cDNA libraries were made and profiled on affymetrix microarray chips.

Project description:We have sequenced miRNA libraries from human embryonic, neural and foetal mesenchymal stem cells. We report that the majority of miRNA genes encode mature isomers that vary in size by one or more bases at the 3’ and/or 5’ end of the miRNA. Northern blotting for individual miRNAs showed that the proportions of isomiRs expressed by a single miRNA gene often differ between cell and tissue types. IsomiRs were readily co-immunoprecipitated with Argonaute proteins in vivo and were active in luciferase assays, indicating that they are functional. Bioinformatics analysis predicts substantial differences in targeting between miRNAs with minor 5’ differences and in support of this we report that a 5’ isomiR-9-1 gained the ability to inhibit the expression of DNMT3B and NCAM2 but lost the ability to inhibit CDH1 in vitro. This result was confirmed by the use of isomiR-specific sponges. Our analysis of the miRGator database indicates that a small percentage of human miRNA genes express isomiRs as the dominant transcript in certain cell types and analysis of miRBase shows that 5’ isomiRs have replaced canonical miRNAs many times during evolution. This strongly indicates that isomiRs are of functional importance and have contributed to the evolution of miRNA genes

Project description:Autoimmune alopecia is a prevalent, highly morbid disease. The inflammatory pathways causing hair loss are not well characterized. We profiled two tissue microarrays comparing healthy skin to scarring alopecia and alopecia areata via spatial transcriptomics to analyze the genes and pathways dysregulated in autoimmune alopecia in direct proximity to the hair follicle.

Project description:In this study, we use single-cell ATAC sequencing (scATAC-seq) and single-cell RNA sequencing (scRNA-seq) to map chromatin accessibility and gene expression in human scalp samples from healthy patients and patients with alopecia areata

Project description:The C3H/HeJ grafted model of alopecia areata was used to determine the efficacy of systemic baricitinib at preventing alopecia or treating established disease. The efficacy of topical baricitinib at treating established alopecia in the C3H/HeJ grafted model was also assessed. Microarrays were performed on skin RNA at week 0 and week 12 after starting treatment in all models. Baricitinib was administered in systemic form at the time of grafting. Skin samples were taken after 12 weeks.
