摘要:

背景:血小板衍化生长因子可诱导肾小球系膜细胞及肾间质多种细胞增殖、迁移、转化及细胞外基质的过表达。

目的:观察血小板衍化生长因子DD/血小板衍化生长因子βR信号通路激活对大鼠肾成纤维细胞细胞增殖及α-平滑肌肌动蛋白表达的影响。
方法:体外培养正常大鼠肾成纤维细胞(NRK-49F),按照血小板衍化生长因子DD刺激质量浓度分为对照组、1 μg/L组、10 μg/L组、50 μg/L组、100 μg/L组,然后根据50 μg/L 血小板衍化生长因子DD刺激不同时间分为对照组、12 h组、24 h组、48 h组。CCK8检测不同血小板衍化生长因子DD质量浓度及血小板衍化生长因子DD作用不同时间对NRK-49F增殖的影响;Real-time PCR检测各质量浓度组血小板衍化生长因子βR、α-平滑肌肌动蛋白mRNA变化;Western blot检测各浓度组血小板衍化生长因子βR、α-平滑肌肌动蛋白蛋白表达变化。
结果与结论:与对照组相比,血小板衍化生长因子DD可明显刺激NRK-49F细胞增殖,呈现剂量依赖性及时间依赖性。血小板衍化生长因子DD可剂量依赖性刺激其相应血小板衍化生长因子βR及α-平滑肌肌动蛋白在mRNA水平及蛋白水平上的表达增加。提示血小板衍化生长因子DD/血小板衍化生长因子βR信号通路的激活可显著刺激NRK-49F细胞的增殖及向肌成纤维细胞的转化。

Abstract:

BACKGROUND: Platelet-derived growth factors can induce proliferation, migration, transformation and extracellular matrix expression of glomerular mesangial cells and renal interstitial cells.

OBJECTIVE: To investigate the effect of activation of platelet-derived growth factor-DD/βR signaling pathway on the proliferation and α-smooth muscle actin expression in rat renal fibroblasts.
METHODS: Normal rat kidney interstitial fibroblasts (NRK-49F) cultured in vitro were divided into the following groups by platelet-derived growth factor-DD concentrations: control, 1 μg/L, 10 μg/L, 50 μg/L, 100 μg/L. And NRK-49Fs were then divided into four groups according to the stimulation time of 50 μg/L platelet-derived growth factor-DD:control, 12 hours, 24 hours, 48 hours. The cell viability of the NRK-49Fs was assessed by Cell Counting Kit-8 after platelet-derived growth factor-DD administration. The mRNA and protein expression levels of platelet-derived growth factor-βR and α-smooth muscle actin in all groups stimulated by different concentrations of platelet-derived growth factor-DD were determined by RT-PCR and western blot, respectively.
RESULTS AND CONCLUSION: Platelet-derived growth factor-DD could facilitate the proliferation rates of the NRK-49Fs at a dose- and time-dependent manner as compared with the control groups. Platelet-derived growth factor-DD could stimulate the mRNA and protein expressions of platelet-derived growth factor-βR and α-smooth muscle actin in a dose-dependent manner. This suggest that the activation of platelet-derived growth facto-DD/βR signaling pathway can obviously promote the proliferation of NRK-49Fs as well as tranformation into myofibroblasts.
