Epigenetic Switch Reshapes Epithelial Stem/Progenitor Cells Signatures and Contributes to Inflammatory Programming in Hidradenitis Suppurativa [RNA-seq]

Project description:By using dual-omics profiling for both chromatin accessibility and gene expression as well as CUT&RUN sequencing for chromatin modification states, we identified that numerous disease-associated inflammatory enhancers were epigenetically activated and co-exist with the transcriptional states of their target genes in basal progenitor cells.

Epigenetic Switch Reshapes Epithelial Stem/Progenitor Cells Signatures and Contributes to Inflammatory Programming in Hidradenitis Suppurativa [CUT&RUN]

Project description:1) By using dual-omics profiling for both chromatin accessibility and gene expression as well as CUT&RUN sequencing for chromatin modification states, we identified that numerous disease-associated inflammatory enhancers were epigenetically activated and co-exist with the transcriptional states of their target genes in basal progenitor cells. 2) By using CUT&RUN sequencing , we identified numerous S100A8 binding DNA sequences in HS epidermal cells.

Epigenetic Switch Reshapes Epithelial Stem/Progenitor Cells Signatures and Contributes to Inflammatory Programming in Hidradenitis Suppurativa [scRNA-seq]

Project description:In this study, we used single-cell RNA-sequencing to reveal how cellular heterogeneity of Hidradenitis Suppurativa (HS) lesional epidermis was reshaped at the transcriptional level. By comparison with healthy interfollicular epidermal basal cells, in HS we revealed marked gene signatures centered on mitotic chromosome segregation, DNA replication and repair as well as cell-cell adhesion and chromatic remodeling. Combing the pseudotime-ordered single-cell trajectory with the spatial localization analysis of defined basal cells, we further identified and validated a global alteration in cellular diversity within HS epidermis characterized by basal I-III cells hyperproliferation, concomitant decreases in superbasal keratinocytes, and phenotypic shifts toward the S100A cluster highly expressing pro-inflammatory genes S100A7/8/9. Cell-cell communication modeling suggested that HS BIII keratinocytes and S100A population serve as a crucial source to trigger IL-1 and IL-10 inflammatory cascades in the disease progression.

Hidradenitis suppurativa and pruritus ani.

Project description:Hidradenitis suppurativa (HS) is a chronic debilitating disorder that can affect any areas bearing apocrine glands. Perineal HS is associated with high morbidity compared with other anatomic regions. Early-stage disease may mimic various other forms of cutaneous disorders, but as HS progresses pathognomonic skin changes occur. Clinical stage can guide the therapeutic approach, but the lowest recurrence rate is obtained by removing all involved skin and subcutaneous fat. Pruritus ani is a complex disease with a multitude of etiologies. Its management can be frustrating and disappointing for the patient and doctor alike. The key is to start with simple treatment options focusing on perianal hygiene and avoidance of the most common offending foods and beverages. If these measures fail, topical medications should be attempted before graduating to perianal injections of methylene blue as a last resort.
