Abstract

Background: Non-small cell lung cancer (NSCLC) consists of a class of heterogeneous diseases. Objective: LncRNAs are exceedingly implicated in the pathogenesis of NSCLC. Herein, the current study set out to illustrate the molecular mechanism of SH3BP5-AS1 in NSCLC cells. Methods: SH3BP5-AS1 expression in clinical NSCLC tissues and its impact on prognosis were analyzed by bioinformatics database. SH3BP5-AS1 expression patterns in NSCLC cell lines (A549/H1299/H1975/H460) and human normal lung epithelial cell lines (BEAS-2B) were examined by RT-qPCR. SH3BP5-AS1 was overexpressed in A549 or silenced in H1975 cells through transfection to assess its effect on proliferation, cell cycle distribution, and apoptosis, apoptosisrelated protein (Cleaved Caspase-3, Bax, Bcl-2) levels, invasive, migratory, and healing capacity through CCK-8, colony formation assay, flow cytometry, Western blot, Transwell, and cell scratch test. Results: SH3BP5-AS1 was under-expressed in NSCLC clinical tissues, and NSCLC patients with low SH3BP5-AS1 expression showed poor prognosis. A549/H1299/H1975/H460 cells had reduced levels of SH3BP5-AS1, with the relative level lowest/highest expression in A549/H1975 cells, respectively. SH3BP5-AS1 overexpression repressed A549 cell proliferation, slowed down cell cycle progression, enhanced apoptosis, elevated Cleared Caspase-3, Bax, suppressed Bcl-2 protein levels, and inhibited migratory, invasive, and scratch healing capacities, while SH3BP5-AS1 silencing brought about the opposite results in H1975 cells. Conclusion: SH3BP5-AS1 could suppress NSCLC cell proliferation, slow down cell cycle progression, stimulate apoptosis, and limit invasion and migration.

LncRNA SH3BP5-AS1 调控非小细胞肺癌细胞的增殖和细胞周期

背景：非小细胞肺癌（NSCLC非小细胞肺癌（NSCLC）是一类异质性疾病。研究目的LncRNA 与 NSCLC 的发病机制有极大的关联。本研究旨在阐明 SH3BP5-AS1 在 NSCLC 细胞中的分子机制。研究方法通过生物信息学数据库分析SH3BP5-AS1在临床NSCLC组织中的表达及其对预后的影响。通过 RT-qPCR 检测了 SH3BP5-AS1 在 NSCLC 细胞系（A549/H1299/H1975/H460）和人类正常肺上皮细胞系（BEAS-2B）中的表达模式。在 A549 细胞中过表达 SH3BP5-AS1，或通过转染在 H1975 细胞中沉默 SH3BP5-AS1，并通过 CCK-8、集落形成试验、流式细胞术、Western 印迹、Transwell 和细胞划痕试验评估 SH3BP5-AS1 对细胞增殖、细胞周期分布、凋亡、凋亡相关蛋白（Caspase-3、Bax、Bcl-2）水平、侵袭、迁移和愈合能力的影响。结果显示SH3BP5-AS1在NSCLC临床组织中低表达，SH3BP5-AS1低表达的NSCLC患者预后较差。A549/H1299/H1975/H460细胞的SH3BP5-AS1水平降低，相对水平最低/最高的分别是A549/H1975细胞。SH3BP5-AS1的过表达抑制了A549细胞的增殖，减缓了细胞周期的进展，增强了细胞凋亡，提高了Caspase-3、Bax的清除率，抑制了Bcl-2蛋白水平，抑制了细胞的迁移、侵袭和划痕愈合能力，而SH3BP5-AS1的沉默则在H1975细胞中带来了相反的结果。结论SH3BP5-AS1能抑制NSCLC细胞增殖、减缓细胞周期进程、刺激细胞凋亡、限制侵袭和迁移。
