摘要
肝纤维化或瘢痕形成是由慢性肝损伤引起的最常见的病理特征,并且被广泛认为是发病率和死亡率的主要原因之一。它的主要特征是肝星状细胞(HSC)活化和细胞外基质(ECM)蛋白沉积过多。大量证据表明,几种非编码RNA(ncRNA)失调,主要是长的非编码RNA(lncRNA),microRNA(miRNA)和环状RNA(circRNA),这有助于HSC的活化和肝纤维化的发展。这些ncRNA不仅与它们的靶基因结合以促进肝纤维化的发展和消退,而且还通过与miRNA纺丝形成信号级联反应而充当竞争性内源RNA(ceRNA)。在这些信号级联反应中,lncRNA-miRNA-mRNA和circRNA-miRNA-mRNA是肝纤维化的起始,进展和消退的关键调节剂。因此,靶向这些相互作用的ncRNA级联可以作为抑制HSC活化以及预防和消退肝纤维化的新型且潜在的治疗靶标。
关键词: 肝纤维化,非编码RNA,竞争性内源RNA,NAFLD,环状RNA,microRNA。
