Abstract Long noncoding RNAs (lncRNAs) act as key regulators controlling complex cellular behaviors in nonsmall cell lung cancer (NSCLC). We investigated the expression of lncRNA PRRT3 antisense RNA 1 (PRRT3-AS1) in paired samples of NSCLC and adjacent normal tissues from a patient cohort in our hospital using real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR) and found that it was significantly higher in NSCLC tissue than in normal tissue, consistent with The Cancer Genome Atlas database. Furthermore, functional investigation revealed that lncRNA PRRT3-AS1 depletion inhibited NSCLC-cell proliferation, colony formation, invasion, and migration, whereas its overexpression exerted… More >

Abstract It has been certified that GABPB1-AS1 is aberrantly expressed and plays as a vital role in some kinds of cancers. However, its expression pattern and functions in non-small cell lung cancer (NSCLC) are still largely unknown. This study aims to assess GABPB1-AS1 expression and biological roles in NSCLC. The expression of GABPB1-AS1 was detected in NSCLC specimens and adjacent normal specimens. CCK8 and Transwell assays were performed to evaluate the effects of GABPB1-AS1 on NSCLC cell proliferation, migration and invasion. Bioinformatics tools and luciferase reporter assays were applied to predict and verify GABPB1-AS1’s direct targets. More >

Abstract Lung cancer is a malignant tumor with high incidence and mortality across the world. The use of immune checkpoint inhibitors for lung cancer has improved the prognosis of some lung cancer patients to a greater extent and provided a new direction for the clinical treatment of lung cancer. Immunotherapy still has limitations in terms of its appropriate population and adverse reactions. Particularly for non-small cell lung cancer (NSCLC) patients with epidermal growth factor receptor (EGFR) mutation, there has been no major breakthrough in current immunotherapy. Whether immunotherapy can bring new benefits after drug resistance is More >

Abstract Objective: The aim of the present study was to investigate the anti-tumor effects of formononetin on human nonsmall cell lung cancer (NSCLC) and its potential molecular mechanism. Methods: A549 cells were treated with different concentrations of formononetin, then detected the cell proliferation, apoptosis and the expression of HIPK2 respectively by MTT assay, flow cytometry analysis and RT-qPCR. Then the interaction between miR- 27a-3p and its target gene HIPK2 was verified through luciferase reporter assay. The expression of miR-27a- 3p, HIPK2, and p53 was detected after being treated with different formononetin concentrations by RT-qPCR and western blot. Results: More >

Abstract Chemotherapy drug resistance is the main cause leading to the relapse and metastasis of non-small cell lung cancer (NSCLC) patients. Our study aimed to investigate the mechanism of pemetrexed resistance in NSCLC. Firstly, the pemetrexed (PEM)-resistant PC-9 and A549 lung adenocarcinoma cell lines (PC-9/PEM and A549/PEM) were established. The expression of thymidylate synthase (TS) in PC-9/PEM, A549/PEM, A549, and PC-9 cells were analyzed by qRT-PCR and western blot. Then, cell viability, colony formation, migration, and invasion were performed on PEM-resistant cells transfected with TS siRNA. The role of EGFR in PEM resistance of PEM-resistant cells… More >

Abstract Increasing evidence indicates that aberrant expressions of some microRNAs are associated with cancer progression. However, the roles and biological mechanisms of miRNA-16-5p in human non-small cell lung cancer (NSCLC) are not to be well studied. Here, we validated that the expression of miR-16-5p was decreased significantly in NSCLC samples and cell lines. The correlation between the clinicopathological features of NSCLC and the miR-16- 5p expression showed that the expression of miR-16-5p in non-small cell lung cancer was linked with the advanced TNM stage, positive lymph node metastasis, with short overall survival (OS). Also, a negative More >

Abstract Non-small cell lung cancer (NSCLC) cells intake and consume glucose at high efficiency by aerobic glycolysis to maintain robust cell growth and resist cell death. MicroRNAs (miRNAs) have been known to play pivotal roles in NSCLC development partly through mediating glycolysis. However, only a few miRNAs have been experimentally confirmed as critical regulators of glycolysis in NSCLC. TCGA datasets were analyzed to screen for differentially expressed miRNAs between NSCLC and normal tissues. The function of miR-1294-5p was determined in NSCLC cells by cell proliferation, glucose uptake, lactate release, and Extracellular Acidification Rate (ECAR) assays. The… More >

Abstract Drug discovery research to fight lung cancer is incessantly challenged by drug resistance. In this study, we used drug-resistant lung cancer stem like cells (A549-CS) to compare the efficacy of standard drugs like cisplatin (DDP) and gemcitabine (GEM) with a novel arylidene derivative IOX-101. A549-CS was derived from regular A549 cells by growing in special media. Resistance proteins were detected using Western blotting. Cell proliferations were assessed by MTT assay. Cytokine release was enumerated using enzyme-linked immunosorbent assay. The effect of drugs on apoptosis and cell cycle was studied with flow cytometry protocols. Apoptosis-related proteins,… More >

Abstract Radiotherapy (RT) is an important treatment for non-small cell lung cancer (NSCLC). However, the major obstacles to successful RT include the low radiosensitivity of cancer cells and the restricted radiation dose, which is given without damaging normal tissues. Therefore, the sensitizer that increases RT efficacy without dose escalation will be beneficial for NSCLC treatment. Eurycomalactone (ECL), an active quassinoid isolated from Eurycoma longifolia Jack, has been demonstrated to possess anticancer activity. In this study, we aimed to investigate the effect of ECL on sensitizing NSCLC cells to X-radiation (X-ray) as well as the underlying mechanisms. The… More >

Abstract MicroRNAs (miRNAs) play crucial roles in tumorigenesis and tumor progression. miR-561 has been reported to be downregulated in gastric cancer and affects cancer cell proliferation and metastasis. However, the role and underlying molecular mechanism of miR-561 in human non-small cell lung cancer (NSCLC) remain unknown and need to be further elucidated. In this study, we discovered that miR-561 expression was downregulated in human NSCLC tissues and cell lines. The overexpression of miR-561 inhibited NSCLC cell proliferation and cell cycle G1 /S transition and induced apoptosis. The inhibition of miR-561 facilitated cell proliferation and G1 /S… More >
