miRNA expression signatures of acne inversa (AI) patients with NCSTN mutations and healthy individuals

Project description:To elucidate the relationship between NCSTN mutations and familial AI pathogenesis by investigating differential miRNA expression, we have employed miRNA microarray profiling as a discovery platform to identify miRNA with the potential to be involved in familial AI pathogenesis. Skin biopsies were obtained from the lesions of AI patients with NCSTN mutations . Control skin tissues were obtained from healthy individuals undergoing cosmetic surgery procedures

transcriptome-wide map of NCSTN-KD and NC Hacat cells

Project description:Acne inversa (AI) is an inflammatory skin disease associated with the nicastrin (NCSTN) mutations. Family history with autosomal dominant inheritance has heen reported in AI patients and are associated with mutations in the γ-secretase subunit, nicastrin (NCSTN), presenilin enhancer 2 (PSENEN), and presenilin-1 (PSEN1). Among them, NCSTN gene has the highest mutation rate. To detect the impact of NCSTN deficiency on AI keratinocytes. Here, using the short hairpin RNA (shRNA)-mediated gene knockdown and RNA sequencing technology, we explored the differentially expressed genes regulated by NCSTN deficiency in HaCaT cells.

Transcription profiling of human acne lesion vs. normal skin from acne and non acne patients

Project description:The pathogenesis of acne has been linked to multiple factors such as increased sebum production, inflammation, follicular hyperkeratinization, and the action of Propionibacterium acnes within the follicle. In an attempt to understand the specific genes involved in inflammatory acne, we performed gene expression profiling in acne patients. Skin biopsies were obtained from an inflammatory papule and from normal skin in six patients with acne. Biopsies were also taken from normal skin of six subjects without acne. Gene array expression profiling was conducted using Affymetrix HG-U133A 2.0 arrays comparing lesional to nonlesional skin in acne patients and comparing nonlesional skin from acne patients to skin from normal subjects. Within the acne patients, 211 genes are upregulated in lesional skin compared to nonlesional skin. A significant proportion of these genes are involved in pathways that regulate inflammation and extracellular matrix remodeling, and they include matrix metalloproteinases 1 and 3, IL-8, human beta-defensin 4, and granzyme B. These data indicate a prominent role of matrix metalloproteinases, inflammatory cytokines, and antimicrobial peptides in acne lesions. These studies are the first describing the comprehensive changes in gene expression in inflammatory acne lesions and are valuable in identifying potential therapeutic targets in inflammatory acne. Experiment Overall Design: total 18 chips. 6 for acne lesion samples, 6 for normal skin samples, 6 for non-acne patient normal skin samples

Changes to energy metabolism, and signal transduction (i.e. Notch and Wnt signalling) define the brain transcriptomic differences between mutations causative for early-onset familial Alzheimer’s disease or familial acne inversa in PRESENILIN 1

Project description:Background: Mutations in PRESENILIN 1 (PSEN1) which still produce a transcript encoding a full-length, but mutant protein are the most common cause of early-onset familial Alzheimer’s disease (EOfAD). The only frameshift mutations found in PSEN1 causes familial acne inversa (fAI) without EOfAD. The molecular consequences of heterozygosity for these mutations, and how they lead to completely different diseases, remains largely unexplored. Objective: To identify the similarities and differences of the effects of heterozygosity for mutations in psen1 causing EOfAD (T428del) or fAI (W233fs) on the brain transcriptome of young adult zebrafish. Methods: RNA sequencing was performed with high read depth on mRNA isolated from the brains of young adult (6 month old) zebrafish arising from a single family which contained either a single, heterozygous EOfAD-like or fAI-like mutation in the endogenous psen1 gene, and their wild type siblings. Results: Both mutations appeared to downregulate genes encoding the ribosomal subunits, and upregulated genes involved in inflammation. Genes involved in energy metabolism appeared to only be affected in EOfAD-like mutants, while genes involved in Notch, Wnt and neutrophin signalling pathways were only significantly altered by the fAI-like mutation. Further investigation of direct transcriptional targets of Notch revealed an apparent increase in Notch signalling. Conclusion: We observed both common, and distinct effects on transcriptomes of the heterozygous mutants compared to their wild type siblings. The distinct effects observed may shed light to how these mutations give rise to completely different diseases.
