特发性肺纤维化(IPF)是一种进行性和致死性肺部疾病,病因不明,病理生理学知之甚少。尽管在IPF中已报告了循环无细胞DNA(ccf-DNA)的血浆水平和代谢组学变化,但ccf-DNA水平与肺纤维化中代谢紊乱之间的相关性尚不清楚。在这里,我们证明了与缓慢进展者和健康对照相比,疾病快速进展的IPF患者中的ccf-双链DNA(dsDNA)增加,并且ccf-dsDNA与IPF患者中的氨基酸代谢、能量代谢和脂质代谢途径相关。
Idiopathic pulmonary fibrosis (IPF) is a progressive and fatal lung disease with unclear aetiology and poorly understood pathophysiology. Although plasma levels of circulating cell-free DNA (ccf-DNA) and metabolomic changes have been reported in IPF, the associations between ccf-DNA levels and metabolic derangements in lung fibrosis are unclear. Here, we demonstrate that ccf-double-stranded DNA (dsDNA) is increased in patients with IPF with rapid progression of disease compared with slow progressors and healthy controls and that ccf-dsDNA associates with amino acid metabolism, energy metabolism and lipid metabolism pathways in patients with IPF.
