Abstract Background Lung adenocarcinoma (LUAD) is one of the most common cancers with high morbidity and mortality worldwide. Long non-coding RNAs (lncRNAs) serve as tumor promoters or suppressors in the development of various human malignancies, including LUAD. Although long intergenic non-protein coding RNA 1089 (LINC01089) suppresses the progression of breast cancer, its mechanism in LUAD requires further exploration. Thus, we aimed to investigate the underlying function and mechanism of LINC01089 in LUAD. Methods The expression of LINC01089 in LUAD and normal cell lines was detected. Functional assays were applied to measure cell proliferation, apoptosis and migration. Besides, mechanism experiments were employed for assessing the interplay among LINC01089, miR-301b-3p and StAR related lipid transfer domain containing 13 (STARD13). Data achieved in this study was statistically analyzed with Student’s t test or one-way analysis of variance. Results LINC01089 expression was significantly down-regulated in LUAD tissues and cells and its overexpression could reduce cell proliferation and migration. Moreover, LINC01089 could regulate STARD13 expression through competitively binding to miR-301b-3p in LUAD. Additionally, rescue assays uncovered that STARD13 depletion or miR-301b-3p overexpression could countervail the restraining effect of LINC01089 knockdown on the phenotypes of LUAD cells. Conclusion LINC01089 served as a tumor-inhibitor in LUAD by targeting miR-301b-3p/STARD13 axis, providing an innovative insight into LUAD therapies. Trial registration Not applicable.

Background/Aims: TNF-α receptor-associated factor (TRAF)-interacting protein with a forkhead-associated (FHA) domain (TIFA) may mediate the impact of TRAF on the development of lung cancer. The current study was conducted to investigate the expression of TIFA in lung adenocarcinoma and its potential role in the regulation of cancer cell proliferation and migration, and its influence on patient survival. Methods: Specimens of lung adenocarcinoma tissues and their adjacent normal lung tissues were obtained from 116 patients who underwent surgical resection of lung cancer. The expression of TIFA in the lung tissues was examined by immunohistochemistry, immunoblotting, and real-time RT-PCR in four different lung cancer cell lines and one normal bronchial epithelial cell line (BEAS-2B). TIFA was silenced by RNAi technique, and cell proliferation was then assessed by the CCK8 method. Furthermore, cell migration was determined by wound-healing trans-well and wound-healing migration assays. Additionally, cell-cycle arrest and apoptosis were assessed by flow cytometry analysis. Results: TIFA was positively detected in 63 (54.3%) out of 116 lung adenocarcinoma specimens, which was significantly higher than the respective rate established in normal tissues adjacent to the tumor (30.1%, p < 0.05). The overall survival rate was significantly lower in the patients with positive TIFA expression than that in the patients with negative TIFA expression (p < 0.05). TIFA was also highly expressed in the lung cancer cell lines (H1299, H1975, and HCC827) tested. It is noteworthy that siRNA suppressed the expression of TIFA, which contributed to the attenuation of cell proliferation and migration, but promoted cell-cycle arrest and apoptosis. Furthermore, the silencing of TIFA caused upregulation of p53, p21, and cleaved-caspase-3, but downregulation of Bcl-2, cyclin D1, and CDK4, as well as phosphorylation of IKKß, IκB, and p65. Conclusions: TIFA may serve as a biomarker in the prediction of lung adenocarcinoma. Furthermore, TIFA may modulate lung cancer cell survival and proliferation through regulating the synthesis of apoptosis-associated proteins.
