“…14 More than 50% of the miRNA genes have been located in tumor-related genomic regions or fragile sites. 28 Zhou's findings indicated that miR-135a promotes cell apoptosis and inhibits cell proliferation, migration, invasion, and tumor angiogenesis by targeting IGF-1 gene through the IGF-1/PI3K/Akt signaling pathway in NSCLC, 29 and MiR-135a inhibits migration and invasion and regulates EMT-related marker genes by targeting KLF8 in lung cancer cells, 30 which is consistent with our study, while Zhang's study showed that MiR-135a overexpression promoted viability, migration, and invasion, but inhibited apoptosis of NCI-H1650 and NCI-H1975 cells. The serum miR-135a level was downregulated in non-small-cell lung carcinoma (NSCLC) patients and was associated with poor prognosis.…”

Purpose To identify potential molecular targets for lung cancer intervention and diagnosis, we analyzed the differential miRNA expression of peripheral blood between lung cancer patients and healthy controls. Methods Three pairs of cases’ and controls’ peripheral blood samples were evaluated for miRNA expression by microarray. 12 miRNAs were selected for RT‐PCR validation and target genes prediction. In addition, 4 miRNAs were selected for future validation by RT‐PCR in a large sample of 145 cases and 55 frequency‐matched healthy controls. Results A total of 338 differentially expressed miRNAs were screened and identified by microarray. According to the fold changes, the top ten upregulated miRNAs were hsa‐miR‐124‐3p, hsa‐miR‐379‐5p, hsa‐miR‐3655, hsa‐miR‐450b‐5p, hsa‐miR‐29a‐5p, hsa‐miR‐200a‐3p, hsa‐miR‐542‐3p, hsa‐miR‐138‐5p, hsa‐miR‐219a‐2‐3p, and hsa‐miR‐4701‐3p, and the top ten downregulated miRNAs were hsa‐miR‐34c‐5p, hsa‐miR‐135a‐5p, hsa‐miR‐132‐3p, hsa‐miR‐3178, hsa‐miR‐4449, hsa‐miR‐4999‐3p, hsa‐miR‐1246, hsa‐miR‐4424, hsa‐miR‐1252‐5p, and hsa‐miR‐24‐2‐5p. RT‐PCR verification of the 12 miRNAs revealed that 5 of 8 upregulated miRNAs, 2 of 4 downregulated miRNAs showed a significant difference between the cases and controls (P < .05). A large number of target genes and their functional set showed overlapping among the 453 predicted target genes of the 12 miRNAs (P < .01). RT‐PCR in the large sample confirmed the significant differential expression level of hsa‐miR‐29a‐5p, hsa‐miR‐135a‐5p, hsa‐miR‐542‐3p, and hsa‐miR‐4491 between cases and controls (P < .05), and three of these microRNA, except hsa‐miR‐29a‐5p, were significant after Bonferroni correction for adjustment of multiple comparisons. Conclusion There was a significant difference in miRNAs expression in the peripheral blood between lung cancer patients and healthy controls, and 4 miRNAs were validated by a large‐size sample.

“…To further explore the detailed mechanism of miR-21 in NSCLC cells, the PI3K/AKT and NF-κB signaling pathways were tested using miR-21 inhibitor. A number of studies showed that PI3K/AKT was involved in human lung cancer [30-33]. Previous studies identified activation of the PI3K/AKT pathway and observed it in human lung carcinomas [34, 35].…”

Background/Aims: Lung cancer is one of the most common malignancies in the world. Apoptosis-stimulating protein of p53 (ASPP2), a tumorigenesis related protein, plays a critical role in the initiation and development of various types of cancers. However, the effect of ASPP2 on lung cancer remains unknown. The purpose of this study aims to investigate the mechanism of ASPP2 regulated by miR-21 in lung cancer in vitro and in vivo. Methods: In the study, migration and invasion assays, apoptosis assay, caspase activity assay, TUNEL staining, real time PCR and western blot were used to investigate the mechanism of ASPP2 regulated by miR-21 in lung cancer in vitro and in vivo. Results: We demonstrated that the miR-21 inhibitor induced apoptosis through inhibiting the PI3K/Akt/NF-κB signaling pathway in non-small cell lung carcinoma (NSCLC). Moreover, ASPP2 was directly targeted by miR-21 in NSCLC cells. Down-regulation of miR-21 suppressed cell migration and invasion, as well as the EMT signaling pathway in NSCLC cells. Furthermore, the miR-21 inhibitor induced cell apoptosis via the caspase dependent pathway in NSCLC cells. The miR-21 inhibitor enhanced caspase-3, 8, 9 activity in NSCLC cells. In addition, the caspase inhibitor significantly reduced the apoptosis induced by the miR-21 inhibitor in NSCLC cells. Conclusions: Our results revealed that the miR-21 inhibitor could induce apoptosis through inhibiting the PI3K/Akt/NF-κB signaling pathway in human NSCLC cells, and might serve as a therapeutic strategy to treat NSCLC.

“…Despite the considerable advances in cancer surgery, chemotherapy, and molecular targeting therapies, the outcome of lung cancer patients remains poor. Invasion and migration of tumor cells are major challenges in the clinical treatment of NSCLC [5]. Consequently, the identification of novel molecules that inhibit the invasion and migration of lung cancer cells is imminent.…”

Background/Aims: MicroRNAs regulate a wide range of biological processes of non-small cell lung cancer (NSCLC). Although miR-598 has been reported to act as a suppressor in osteosarcoma and colorectal cancer, the physiological function of miR-598 in NSCLC remains unknown. In this study, the role of miR-598 in NSCLC was investigated. Methods: Quantitative real-time polymerase chain reaction (qRT-PCR) was conducted to estimate the expression of miR-598 and Derlin-1 (DERL1) in both NSCLC tissues and cell lines. Immunohistochemistry (IHC) analyzed the association between the miR-598 expression and epithelial-mesenchymal transition (EMT) hallmark genes (E-cadherin, Vimentin) by staining the tumors representative of the high- and low-expression groups. The effect of miR-598 and DERL1 on invasion and migration was determined in vitro using transwell and wound-healing assays. The molecular mechanism underlying the relevance between miR-598 and DERL1 was elucidated by luciferase assay and Western blot. Western blot assessed the expression levels of EMT hallmark genes in cell lines. Xenograft tumor formation assay was conducted as an in vivo experiment. Results: In this study, a relatively low level of miR-598 and high DERL1 expressions were found in NSCLC specimens and cell lines. IHC results established a positive correlation between the miR-598 expression and E-cadherin and a negative with Vimentin. DERL1 was verified as a direct target of miR-598 by luciferase assay. In vitro, the over-expression of miR-598 negatively regulated DERL1 and EMT for the suppression of invasion and migration. In vivo, the over-expression of miR-598 could inhibit tumor cell metastasis in NSCLC. Conclusions: These findings for the first time revealed that miR-598, as a tumor suppressor, negatively regulate DERL1 and EMT to suppress the invasion and migration in NSCLC, thereby putatively serving as a novel therapeutic target for NSCLC clinical treatment.
