ABSTRACT: To investigate whether transfection with Krüppel-like factor 6 splice variant 1 (KLF6SV1) siRNA can inhibit proliferation of human lens epithelial cell (HLEC).
Plasmid containing KLF6SV1 siRNA was used to decrease the level of KLF6SV1 protein in HLEC. The expression of protein27 kinase inhibition protein 1 (p27(kip1)) and proliferation cell nuclear antigen (PCNA) was tested with western blot. Cell proliferation was assayed by 3-(4,5-dimethylthiazolyl-2-)-2,5-diphenyltetrazoliumbromide (MTT) assay and bromodeoxyuridine (BrdU) incorporation.
KLF6SV1 siRNA can decrease KLF6SV1 expression which leads to increased levels of p27(kip1) and decreased expression of PCNA in HLEC. Cells transfected with pKLF6SV1 siRNA showed less viability compared with the control group in vitro.
KLF6SV1 siRNA can effectively inhibit HLEC proliferation. It can be regarded as a novel target to treat posterior capsular opacity (PCO).
