The regulation of long non-coding RNAs (lncRNAs) has been implicated in the pathogenesis of sepsis-induced acute kidney injury (SI-AKI). Nevertheless, the specific roles of individual lncRNAs in this process remain unclear. This study investigated the expression of lncRNA AP001007 in lipopolysaccharide (LPS)-induced HK-2 cells and in the peripheral blood of sepsis patients. The result shows that LPS treatment downregulated the expression of AP001007 in HK-2 cells and that circulating levels of AP001007 were lower in sepsis patients. Furthermore, overexpressing AP001007 in HK-2 cells improved cell viability, mitochondrial activity, and survival when exposed to LPS. Additionally, LPS-treated HK-2 cells secreted fewer pro-inflammatory cytokines when AP001007 was overexpressed. Similar protective effects were observed in human kidney organoids (HKOs) subjected to LPS. These findings suggest that AP001007 confers protection against LPS-induced damage in HK-2 cells and HKOs, highlighting its potential as a regulator of SI-AKI.
长链非编码 RNA(lncRNAs)的调节已被认为与脂多糖(LPS)诱导的急性肾损伤(SI-AKI)的发病机制有关。然而,个别 lncRNAs 在这个过程中的具体作用仍不清楚。本研究探讨了 lncRNA AP001007 在 LPS 诱导的 HK-2 细胞和脓毒症患者外周血中的表达。结果表明,LPS 处理下调了 HK-2 细胞中 AP001007 的表达,脓毒症患者的循环 AP001007 水平较低。此外,在 LPS 处理的 HK-2 细胞中过表达 AP001007 可提高细胞活力、线粒体活性和存活率。此外,当过表达 AP001007 时,LPS 处理的 HK-2 细胞分泌的促炎细胞因子减少。在 LPS 处理的人肾类器官(HKOs)中也观察到类似的保护作用。这些发现表明,AP001007 赋予 HK-2 细胞和 HKOs 对 LPS 诱导损伤的保护作用,突出了其作为 SI-AKI 调节剂的潜力。
