文章隶属:liyuan Gao 肝纤维化是医疗领域的困难问题。我们先前报道说,姜黄(一种生物活性物质)可能会抑制肝正正弦内皮细胞(LSEC)的病理血管生成,并发挥良好的抗肝纤维化作用。但是,需要进一步阐明姜黄素抑制血管生成的机理。在这里,我们专注于姜黄素如何抑制ts LSEC angiogenesis in liver fibrosis.
MATERIALS AND METHODS: Primary rat LSECs were cultured in vitro, and various molecular experiments including real-time PCR, western blot, immunofluorescence, tube formation assay and transwell migration assay were used to clarify the potential mechanism of姜黄。应用四氯化碳(CCL)来创建小鼠肝纤维化模型。吸收血液和肝脏来阐明姜黄素在体内的功效。
关键发现: 我们发现姜黄素可以有效地抑制lsececyen Interro的Lsececyeens。有趣的是,此过程可能取决于姜黄抑制转录因子KLF5的表达。小鼠实验还表明,姜黄素可以通过降低KLF5表达来减轻慢性肝损伤。此外,我们建议姜黄素可以减少线粒体ROS的产生并改善线粒体LSEC中的IAL形态。 More importantly, we proved that curcumol could suppress KLF5-mediated LSEC angiogenesis by inhibiting ROS/ERK signaling.
SIGNIFICANCE: We suggested that transcription factor KLF5 could be considered as a new target molecule of curcumol in improving liver fibrosis, and pointed out that姜黄素靶向ROS/ERK介导的KLF5表达可以抑制LSEC血管生成。这为姜黄素改善肝纤维化提供了一个新的理论基础。
