Abstract:
ObjectiveTo investigate the effects of targeted silencing of Runt-related Transcription Factor 3 （RUNX3） on the proliferation and migration of Mouse Hepatic Stellate Cells （HSCs）， as well as subsequent collagen deposition. MethodsMouse hepatic stellate cell line （JS-1） was selected and then morphologically observed and identified under a microscope. After the cells had fully adhered， they were treated with 5 ng/mL of transforming growth factor beta 1 （TGF-β1） for 24 hours to induce hepatic stellate cell activation. Furthermore， a RUNX3 silencing model was established using RUNX3 lentiviral infection. The experiment was divided into four groups： Control group， TGF-β1 group， TGF-β1+siRNA-NC group， and TGF-β1+siRNA-RUNX3 group. Protein expression changes of RUNX3， alpha-smooth muscle actin （α-SMA）， and Alpha 1 type I collagen （Collagen I） were detected using Western blot method. Cellular immunofluorescence assays were employed to investigate the deposition changes of α-SMA and RUNX3 in hepatic stellate cells. RT-qPCR was utilized to examine the mRNA expression changes of RUNX3， α-SMA， and Collagen I. The proliferative capacity of hepatic stellate cells was assessed using Edu staining. The migratory ability of hepatic stellate cells was evaluated through wound healing assays and Transwell migration experiments. ResultsCompared with Control group， a significant elevation in RUNX3 was observed in the TGF-β1-induced activated HSCs （P<0.01）. Meanwhile， the protein and mRNA levels of fibrosis-related markers and α-SMA and Collagen I were significantly upregulated （P<0.001）. Additionally， the proliferation and migration capabilities of HSCs were significantly enhanced （P<0.001）. In contrast， when compared to TGF-β1+siRNA-NC group， TGF-β1+siRNA-RUNX3 group exhibited a notable decrease in RUNX3 and other related indicators， such as the protein and mRNA levels of α-SMA and Collagen I （P<0.05）. Concurrently， the proliferation and migration capabilities of HSCs were significantly inhibited in TGF-β1+siRNA-RUNX3 group （P<0.01）. ConclusionSilencing RUNX3 can inhibit the deposition of collagen and the proliferation and migration of hepatic stellate cells. Conversely， RUNX3 promotes the proliferation and migration capabilities of HSCs， thereby facilitating the activation of HSC.
