Abstract
Aim The purpose of this research was to discuss the effects and relative mechanisms of ILK in PBOO by vivo and vitro study.
Materials and methods The SD rats were divided into Normal, Sham and Model groups. Collecting Bladder outlet tissue, observation pathology and fibrosis levels by H&E and Masson staining. Measuring cell apoptosis and cell viability by TUNEL and p-histone H3 staining, ILK protein were evaluated by WB and IHC assay in Bladder outlet tissue. Using TGF-β1 stimulating BSMC cell to make PBOO cell model. Measuring cell proliferation by CCK-8 assay; Relative gene and proteins expression were evaluated by immunofluorescence, WB and RT-qPCR assay.
Results Compared with Normal group, bladder weight, collage fiber area, apoptosis cell number and cell viability were significantly difference with ILK protein significantly increasing in bladder outer tissues of Model group (P < 0.05, respectively). In vitro cell experiment, ILK overexpression had effects to stimulate cell proliferation via TLR4/NF-κB(p65) pathway; however, with ILK knockdown, the cell proliferation was significantly depressed via regulation TLR4/NF-κB(p65).
Conclusion ILK play an important role in PBOO induced cell proliferation, ILK knockdown had effects to improve PBOO induced cell hyper-proliferation via depressing TLR4/NF-κB(p65) pathway.
