    摘要:

    目的 基于转录组学测序技术,观察肺纤维化进程中 GIMAP8 和 SEC14L5 在尘肺患者和矽肺小鼠模型中的表达变化,为阐明肺纤维化的发生和发展提供理论依据。 方法 将雄性 C57BL/ 6 小鼠随机分为 PBS 组(磷酸缓冲盐溶液)和 Silica 组(二氧化硅悬液),通过非暴露式气管插管方式在第 0、14 天向 Silica 组小鼠灌注 100mg / mL 二氧化硅悬液 50 μL,PBS 组灌注等量磷酸缓冲盐溶液。 第 28 天时评估小鼠肺功能并处死所有小鼠,进行肺组织形态观察、纤维化评价以及 mRNA 水平的检测。 结果 与健康对照者相比,尘肺患者筛选出有显著表达差异的 mRNA 共 584 种,其中 242 种 mRNA 显著上调,342 种 mRNA 显著下调。 富集分析显示,这些差异表达的mRNA 主要参与了 P53、NF-κB、TNF、AMPK 等信号通路。 PBS 组小鼠肺结构正常,而 Silica 组小鼠呈现肺泡结构破坏,胶原纤维沉积和纤维团块。 肺组织中 GIMAP8 表达上调,SEC14L5 表达下调。 Silica 组小鼠肺功能有所下降。 结论 在尘肺患者及矽肺小鼠模型中,GIMAP8 和 SEC14L5 可能参与肺纤维化的发生和发展,这可能为预防和治疗这些疾病提供分子理论基础。

    Abstract:

    Objective Utilizing transcriptomic sequencing, this study aimed to monitor the expression alterations of GIMAP8 and SEC14L5 throughout the progression of pulmonary fibrosis, thereby providing insights into the underlying mechanisms of its pathogenesis and evolution. Methods C57BL/ 6 male mice were assigned in a randomized manner to either the Silica or PBS group. The Silica group underwent non-exposed endotracheal intubation on days 0 and 14 with 50 μL 100 mg / mL silica suspension, while the control group received 50 μL phosphate-buffered saline solution. On day 28,lung function was detected and the mice were sacrificed, and lung morphology, fibrosis, and mRNA levels were observed. Results When contrasted with individuals in good health, a differential expression analysis of mRNA in patients with pneumoconiosis identified a total of 584 mRNAs with significant expression differences. Among these, the expression of 242 mRNA was observed to be markedly elevated, while that of 342 mRNA was found to be considerably diminished. The enrichment analysis indicated that the primarily affected mRNAs with altered expression were associated with pathways such as p53, nuclear factor-κB, tumor necrosis factor, AMP-activated protein kinase, and other signaling pathways. In the Silica mice, the alveolar structures were compromised, characterized by the presence of collagen fiber accumulation and the formation of fibrous masses. In contrast, the PBS mice maintained a normal pulmonary architecture. GIMAP8 expression was up-regulated whereas SEC14L5 expression was down-regulated in lung tissues in the Silica mice, and mice in the Silica group had poorer lung function. Conclusions The onset and progression of pulmonary fibrosis may be significantly influenced by GIMAP8 and SEC14L5 expression in patients with pneumoconiosis and in silicosis animal models. This association could serve as a foundational molecular insight, paving the way for the development of preventative and therapeutic strategies against these conditions.
