Analysis of differential expression of genes of structural and regulatory proteins of connective tissue as factors associated with the vaginal prolapse
The article presents data on the differential expression of genes of structural and regulatory proteins of connective tissue (COLIA1, fibronectin, elastin, TGF-β1, LOX) in women with pelvic organ prolapse and stigmas of undifferentiated connective tissue dysplasia (UCTD) compared to patients with pr...

| description | The article presents data on the differential expression of genes of structural and regulatory proteins of connective tissue (COLIA1, fibronectin, elastin, TGF-β1, LOX) in women with pelvic organ prolapse and stigmas of undifferentiated connective tissue dysplasia (UCTD) compared to patients with prolapse but without UCTD stigmas.
Research objectives: analysis of the prognostic significance of differential expression of structural and regulatory genes of connective tissue proteins COLIA1, fibronectin, elastin, TGF-β1, LOX as factors associated with the vaginal prolapse among Ukrainian women.
Materials and methods. Vaginal tissue samples were taken from 18 patients at the menopausal age with vaginal prolapse III, IV degree, which required surgical correction during vaginal hysterectomy and/or plastic surgery of vaginal walls. The main group included 11 patients with clinical and anamnestic UCTD stigmas, the comparison group included 7 women without it. Gene expression analysis of structural and regulatory proteins of the extracellular matrix of connective tissue was performed using real-time quantitative polymerase chain reaction. The relative number of transcripts of the studied genes was normalized by the expression level of the GAPDH gene. The data were calculated using the 2–ΔΔCt method.
Results. There was decrease in gene expression of the main structural proteins of the extracellular matrix of the connective tissue: COLIA1 (t=-1.7; p=0.044), fibronectin (t=1.66; p=0.047), elastin (t=-1.75, p=0,04), gene of the regulatory protein LOX (t=-1.8, p=0.035) and no statistically significant difference in the TGF-β1 gene in patients with pelvic organ prolapse and clinical and anamnestic UCTD stigmas.
Conclusions. Statistically significant lower expression of the genes of the main structural proteins of the extracellular matrix of the connective tissue and the gene of the regulatory protein LOX in patients with pelvic organ prolapse and clinical and anamnestic UCTD stigmas is evidence of the importance of genetically determined pathological remodeling of the connective tissue in the etiology of genital prolapse. |
