Later, we found that APOM was also downregulated in laryngeal carcinoma tissues and cell lines, and inhibited laryngeal carcinoma progression. HCG11 positively regulated APOM at the post-transcriptional level. MiR-4469 was predicted to have the binding sites of HCG11 and APOM. Furthermore, it was demonstrated that HCG11 absorbed miR-4469 to upregulate APOM expression. Finally, it was indicated that the repression of APOM rescued the effects of HCG11 overexpression on cell proliferation and cell apoptosis. CONCLUSIONS This study uncovered that HCG11 sponged miR-4469 to suppress laryngeal carcinoma progression by upregulating APOM expression.OBJECTIVE To verify that miR-92b inhibits proliferation and invasion of lung cancer by targeting EZH2. MATERIALS AND METHODS The expression levels of miR-92b and EZH2 in human bronchial epithelial cell line BEAS-2B and human lung cancer cell line (A549, NCI-H23, NCI-H358, NCI-H1975, PC-9) were detected, and miR-92b mimic, sh-EZH2 expression vector, and plasmid blank vector (blank group) were constructed. Blank group, miR-92b mimic, miR-92b mimic+sh-EZH2 group (combined group) were set up, MTT and transwell were used to detect the proliferation and invasion ability of A549 and NCI-H23 cells, and fluorescein report verified the regulatory relationship of miR-92b to EZH2. RESULTS The expression level of miR-92b in A549, NCI-H23, NCI-H358, NCI-H1975, and PC-9 cells was lower than that in BEAS-2B cells (p0.05). Cell proliferation ability and invasion ability of A549 cells and NCI-H23 cells in miR-92b mimic group were lower than those in blank group (p less then 0.05), while those in combined group were higher than those in miR-92b mimic group (p less then 0.05). CONCLUSIONS MiR-92b inhibits proliferation and invasion of lung cancer cells through targeted inhibition of EZH2, which is a potential target for future treatment of lung cancer.OBJECTIVE The long non-coding RNA double homeobox A pseudogene 8 (DUXAP8) was reported to be involved in the initiation and development of multiple cancers. However, the detailed biological role of DUXAP8 in non-small-cell lung cancer (NSCLC) remains unclear. Herein, we aimed to explore the biological function and molecular mechanism of DUXAP8 in NSCLC. PATIENTS AND METHODS The levels of DUXAP8, microRNA-498 (miR-498) and tripartite motif-44 (TRIM44) were detected by Quantitative Real-time polymerase chain reaction (qRT-PCR). The cell proliferation, migration and invasion were detected by 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) and transwell assays. Protein expression levels were detected by Western blot. The target relationships among DUXAP8, miR-498 and TRIM44 were predicted by starBase2.0 and confirmed using luciferase reporter and RNA pull-down assays. To detect the role of DUXAP8 in vivo, tumor xenografts were created. RESULTS DUXAP8 and TRIM44 were upregulated in NSCLC tissues and cell lines, while miR-498 was downregulated. Functionally, knockdown of DUXAP8 could repress proliferation, migration, invasion, Epithelial-Mesenchymal Transition (EMT) and phosphorylation of AKT/mTOR in NSCLC cells. This inhibition could be restored by inhibiting miR-498 or overexpressing TRIM44. Furthermore, we also observed a positive correlation between DUXAP8 and TRIM44 expression, while the expressions of miR-498 and DUXAP8, as well as miR-498 and TRIM44, were negatively correlated in NSCLC tissues. Importantly, DUXAP8 could regulate the expression of TRIM44 via miR-498. Moreover, knockdown of DUXAP8 notably decreased the xenograft tumor volume, weight and number of metastatic nodules in vivo. CONCLUSIONS Our results identified that LncRNA DUXAP8 could regulate cell proliferation, metastasis and EMT in NSCLC cells by inhibiting miR-498 through the activation of TRIM44-mediated AKT/mTOR pathway.OBJECTIVE Previous studies have shown that ubiquitin specific protease 3 (USP3) is an oncogene. However, the role of USP3 in non-small cell lung cancer (NSCLC) has not been reported. This study aims to explore the expression characteristics of USP3 in NSCLC, and its regulation on the proliferative capacity of NSCLC cells. PATIENTS AND METHODS Quantitative Real Time-Polymerase Chain Reaction (qRT-PCR) was performed to examine the expression levels of USP3 and RNA Binding Motif 4 (RBM4) in 42 pairs of tumor tissues and adjacent tissue specimens collected from NSCLC patients. Meanwhile, the correlation between the messenger ribonucleic acid (mRNA) expressions of USP3 and RBM4, and the clinical indicators and prognosis of NSCLC patients were analyzed. selleck inhibitor At the same time, mRNA expression of USP3 in NSCLC cell lines was further verified by the qRT-PCR method. In addition, USP3 knockdown and overexpression models were constructed using lentivirus in NSCLC cell lines H1299 and SPCA1. Cell counting kit-8 (CCK-8), cell cstrated that USP3 can be targeted by RBM4. Rescue experiments revealed that RBM4 was responsible for NSCLC progression regulated by USP3. CONCLUSIONS The above studies indicated that USP3 expression was remarkably up-regulated in NSCLC tissues, which was closely related to the pathological staging and poor prognosis of NSCLC patients. Therefore, USP3 might accelerate the proliferation of NSCLC cells via regulating RBM4.OBJECTIVE Chemoresistance is the leading cause of recurrence in non-small cell lung cancer (NSCLC). The long non-coding RNA (lncRNA) cancer susceptibility candidate 2 (CASC2) inhibits the tumorigenesis of various cancers. However, the regulatory function of CASC2 on the chemoresistance of NSCLC remains unclear. PATIENTS AND METHODS The levels of CASC2 and miR-18a in cisplatin (DDP)-resistant NSCLC tissues and cell lines were evaluated by quantitative Polymerase Chain Reaction (qPCR). The role of low CASC2 levels on overall survival in patients with NSCLC was tested using the log-rank test. The Chi-squared test was used to assess the relation between CASC2 expression and clinicopathological features of NSCLC patients. Cell Counting Kit-8 (CCK-8) assays tested the cell proliferation of cisplatin-resistant NSCLC cells (H226/DDP and A549/DDP). The underlying regulatory mechanism between CASC2 and miR-18a or miR-18a and interferon regulatory factor 2 (IRF-2) was predicted by bioinformatics and verified by a Dual-Luciferase reporter assay, RNA transfection, qPCR, and Western blotting.
