本研究旨在探讨人胎儿成骨细胞系 hFOB 1.19 中 septin 7 (SEPT7) 与褪黑激素诱导的细胞凋亡之间的关联。 MicroRNA (miR)-590-3p 是通过在不同数据库(miRDB、DIANA 和 Targetscan)中识别靶向 SEPT7 的重叠 miRNA 来鉴定的。通过流式细胞术分析评估细胞凋亡。 SEPT7 的小干扰 RNA 和 miR-590-3p 抑制剂用于基因沉默,并通过逆转录定量聚合酶链反应评估效率。蛋白质印迹用于测量与介导内质网应激和褪黑激素诱导的细胞凋亡途径相关的蛋白质的表达。本研究确定SEPT7是miR-590-3p的潜在靶标,并证明SEPT7与介导人成骨细胞系hFOB 1.19中miR-590-3p的促凋亡作用相关。高浓度的褪黑激素可能会抑制 miR-590-3p 的表达,从而导致促进细胞凋亡的靶基因上调。
The present study aimed to investigate the association between septin 7 (SEPT7) and melatonin-induced apoptosis in the human fetal osteoblastic cell line hFOB 1.19. MicroRNA (miR)-590-3p was identified by identifying overlapping miRNAs that target SEPT7, across different databases (miRDB, DIANA and Targetscan). Apoptosis was assessed via flow cytometric analysis. Small interfering RNA of SEPT7 and a miR-590-3p inhibitor were used for gene silencing and the efficiency was assessed by reverse transcription-quantitative polymerase chain reaction. Western blotting was used to measure the expression of proteins associated with pathways mediating endoplasmic reticulum stress and melatonin-induced apoptosis. The present study identified that SEPT7 was a potential target of miR-590-3p and demonstrated that SEPT7 is associated with mediating the pro-apoptotic effect of miR-590-3p in human osteoblast cell line hFOB 1.19. High concentrations of melatonin may result in the inhibition of miR-590-3p expression, leading to the upregulation of target genes that promote apoptosis.
