RESUMEN
A sudden rise in intra-abdominal pressure that causes the pressure in the bladder to rise during physical movement and/or activity, such as coughing, sneezing, laughing, running, or weightlifting, is known as stress urinary incontinence. This condition causes an uncontrollable overflow of urine. The study's goal was to determine whether effector molecules, specifically ADP ribosylation factor GTPase activated protein 3, might play a part in the female pelvic floor muscle's ability to heal after suffering damage during vaginal delivery. Pelvic floor muscle samples were taken from women who had at least one vaginal delivery and were enrolled in either the IU group (n = 45; issue of stress urinary incontinence) or the NL group (n = 85; no issue of stress urinary incontinence) depending on whether they had a problem with stress urinary incontinence. Vesicle transport-related genes in female pelvic floor muscle injury repair were discovered using Gene Expression Omnibus. For gene analysis and screening, RT-qPCR was employed. On the first day following injury, the expression level of ARFGAP3 mRNA increased by 2.8 times (p 0.05) and by 5 times (p 0.01) on the third day. On the first day following damage, STMN1 mRNA expression rose by 0.3 times (p 0.05). On the first day following injury, the expression level of THBS2 mRNA increased by 1.6 times (p 0.01). On the third day following the injury, the expression level of PLXNB2 mRNA increased by 1.2 times (p 0. 01), and on the fifth day following the injury, it increased by 2.5 times (p 0. 01). After pelvic floor muscle damage, the mRNA expression levels of the CSF1R, ANXA4, and EMR1 genes dropped. Between those with and without pelvic floor muscle damage, there was no statistically significant difference in the expression levels of LGARLS3, KDELR3, and KIF20A mRNA (p > 0. 05 for all). The differential expression of genes after pelvic floor muscle injury can identify the target in the process of pelvic floor muscle injury repair and regeneration.
