Hidradenitis suppurativa (HS) is a chronic, inflammatory skin disease characterized by massive immune cell infiltrate, tissue destruction and extensive fibrosis. We aimed to elucidate the role of fibroblasts in pathophysiology HS. Single-cell RNA-sequencing was performed on chronic lesional samples 8 HS patients controls. Ex vivo experiments were primary dermal from lesions (n=3). Fibroblast su...
BACKGROUND High serum estradiol (E2) levels following ovarian stimulation lead to reduced implantation and pregnancy rates, yet the underlying mechanisms remain unknown. We investigated if aberrant expression of genes in the Wnt-signaling pathway may be involved. METHODS Microarray and real-time PCR analysis were performed to analyze gene expression profiles of endometrial samples taken at da...
the association of secreted frizzled related protein type 4 (sfrp4) as an antagonist of wnt mole-cules in apoptotic events has been reported previously. moreover, its increased expression has been reported in the ovary of women with polycystic ovary (pco). we have demonstrated in-creased sfrp4 in pco-induced rat ovary related to an increased number of apoptotic follicles showing nuclear ?cateni...
Development of the metanephric kidney is an experimental model system to analyze interactions between mesenchymal and epithelial cells and mesenchymal-epithelial transition. To study the underlying genetic mechanisms we employed organ culture and differential display PCR to identify genes regulated upon induction of mesenchymal cells. One of the genes found encodes the secreted frizzled related...
B-cell chronic lymphocytic leukemia (CLL) is characterized by a clonal accumulation of mature neoplastic B cells indicating disruption of apoptosis. Restriction Landmark Genome Scanning was done to identify novel target genes silenced by CpG island methylation in CLL. Secreted frizzled-related protein 4 (SFRP4), a negative regulator of the Wnt signaling pathway, was found to be frequently methy...
Transcriptional silencing by CpG island hypermethylation plays a critical role in endometrial carcinogenesis. In a collection of benign, premalignant and malignant endometrial lesions, a methylation profile of a complete gene panel, such steroid receptors (ERα, PR), DNA mismatch repair (hMLH1), tumor-suppressor genes (CDKN2A/P16 and CDH1/E-CADHERIN) and WNT pathway inhibitors (SFRP1, SFRP2, SFR...
Wingless-type MMTV integration site family member (WNT) signaling and WNT-inhibitors have been implicated in regulation of adipogenesis, insulin resistance, pancreatic function, and inflammation. Our goal was to determine serum proteins involved in WNT signaling (WNT5 and WISP2) and WNT inhibition (SFRP4 and SFRP5) as they relate to obesity, serum adipokines, insulin resistance, insulin secreti...
Secreted frizzled-related proteins (SFRPs), containing five family members (SFRPs 1-5) are putative extracellular Wnt inhibitors. Given their abilities to inhibit Wnt signalling, as well as the loss of SFRP1 in many cancers, this family is generally considered to be tumour suppressive. In this study we analyzed gene expression, promoter methylation and survival data from over 8000 tumour and no...
Hidradenitis suppurativa (HS) is a chronic, inflammatory skin disease characterized by massive immune cell infiltrate, extensive fibrosis, and tissue destruction. We aimed to elucidate the role of fibroblasts in pathophysiology HS. Single-cell RNA-sequencing was performed on chronic lesional samples 6 HS patients 7 controls. Spatial sequencing 4 samples. Fibroblast subclustering revealed subset...
