Gene expression in urinary incontinence and pelvic organ prolapse: a review of literature

Purpose of review: To review current evidence on gene expression in women with urinary incontinence and pelvic organ prolapse (POP).

Recent findings: Our literature review revealed numerous genes that are associated with urinary incontinence and POP. For overactive bladder and urge urinary incontinence, four genes were highlighted: adrenergic receptor β3, Rho guanine nucleotide exchange factor 10, Rho-associated coiled-coil containing protein kinase 2, and potassium two pore domain channel subfamily K member-1. For Stress Urinary incontinence (SUI), 13 genes were included: skin-derived antileukoproteinase, collagen type XVII alpha 1 chain, plakophilin 1, keratin 16, decorin, biglycan, protein bicaudal D homolog 2, growth factor receptor-bound protein 2, signal transducer and activator of transcription 3, apolipoprotein E, Golgi SNAP receptor complex member 1, fibromodulin, and glucocerebrosidase. For POP seven genes were identified: homeobox A13, matrix metallopeptidase 9, estrogen receptor 2, collagen type XIV alpha 1 chain, collagen type V alpha 1 chain, collagen type IV alpha 2 chain, and catenin beta 1.

Summary: The current review highlights many genes which are potential biomarkers and targets for drug development.
