MYG1 promoted the proliferation, migration and invasion of A549 and H1993 cells. Selleck Lonafarnib In addition, MYG1 inhibited autophagy via the AMP-activated protein kinase/mTOR complex 1 signaling pathway. Collectively, the present results suggested that MYG1 may serve an oncogenic role in LUAD and may be a potential therapeutic target for LUAD.Gynecological cancers, including breast, ovarian, uterine, vaginal, cervical and vulvar cancers are among the major threats to modern life, particularly to female health. Long non-coding RNAs (lncRNAs) play critical roles in normal development of organisms, as well as the tumorigenesis process, and metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) is a large infrequently spliced lncRNA, which have been implicated in different gynecological cancers. MALAT1 is overexpressed in breast, ovarian, cervical and endometrial cancers, which initiates cancer progression by inducing changes in the expression of several anti-apoptotic and epithelial-to-mesenchymal transition-related genes. Targeting MALAT1 is an important strategy to combat gynecological cancers, and application of RNA-interference technology and chemotherapeutic process are crucial to target and minimize MALAT1 activity. The present review discusses the role of MALAT1 in gynecological cancers, and potential strategies to target this lncRNA to develop cancer therapeutics. However, further clinical studies are required to determine the prognostic potential of MALAT1 in gynecological cancers.Eupafolin is a flavonoid extracted from common sage. Previous studies have reported that Eupafolin has antioxidant, anti-inflammatory, and anti-tumor effects. However, its role in breast cancer remains unclear. The present study investigated the effects and underlying mechanism of action of Eupafolin using breast cancer cell lines. The effects of Eupafolin on breast cancer cell proliferation, migration, apoptosis and the cell cycle were determined. Cell viability and Transwell assays, reverse transcription-quantitative PCR, flow cytometry and western blot analysis were used in this study. The data showed that the proliferation, migration and invasion ability of EO771 cells treated with Eupafolin was significantly decreased, and the apoptosis rate was increased compared with that of the control. The protein levels of Bax and cleaved caspase 3 increased, whereas that of Bcl-2 decreased. In addition, Eupafolin treatment also caused the proliferation of breast cancer cells to be arrested at the G0/G1 phase. Furthermore, results from western blotting indicated that Eupafolin treatment decreased the protein levels of p-PI3K, p-Akt and p-mTOR. Taken together, the present findings demonstrate that Eupafolin has a significant inhibitory effect on the proliferation of EO771 cells, inhibits cell migration and invasion, and promotes cell apoptosis, thereby causing G0/G1 phase arrest, at least partially through the PI3K/Akt/mTOR signaling pathway. Therefore, the findings provide novel insights regarding the use of Eupafolin for the treatment of breast cancer.Striatin-4 (STRN4 or Zinedin) is a scaffolding protein belonging to the mammalian STRN family of proteins and consists of multiple functional signaling domains. Due to its numerous signaling complexes, STRN4 has been reported to be involved in the tumorigenesis of various cancer types, including colon cancer, liver cancer and prostate cancer. However, few studies on STRN4 have been conducted in bladder cancer, and its prognostic role in bladder cancer remains unknown. The present study aimed to investigate the expression levels of STRN4 in bladder transitional cell carcinoma and evaluate the prognostic role of STRN4. STRN4 expression in clinical specimens was analyzed using immunohistochemistry and reverse transcription-quantitative PCR. It was demonstrated that STRN4 expression was significantly associated with clinical parameters such as tumor size, muscle invasion depth and pathological tumor grade. Abnormal STRN4 expression was typically associated with worse overall survival time and outcome when compared with the low STRN4 expression group. Using multivariate analysis, it was reported that STRN4 was an independent prognostic biomarker for survival time in bladder transitional cell carcinoma. Although the specific biological mechanisms of STRN4 in bladder cancer still remain to be elucidated, STRN4 expression could be a prognostic indicator in bladder cancer.Methyltransferase-like 1 (METTL1) is a transfer RNA and microRNA modifying enzyme. However, its role in lung adenocarcinoma (LUAD) remains unknown. The present study aimed to investigate the effect of METTL1 in LUAD and determine the association between METTL1 expression and prognosis of patients with LUAD. The expression profile of METTL1 in LUAD tissues was downloaded from public cancer databases and analyzed using the Gene Expression Profiling Interactive Analysis database and UALCAN online software. In addition, the association between METTL1 expression and prognosis of patients with LUAD was assessed using the Kaplan-Meier Plotter software. The effect of METTL1 in the A549 cell line was determined in vitro via overexpression and knockdown experiments. The results demonstrated that METTL1 was upregulated in LUAD tissues, and its increased expression was associated with unfavorable prognosis. Furthermore, METTL1 promoted proliferation and colony formation of A549 cells, and inhibited autophagy via the AKT/mechanistic target of rapamycin complex 1 signaling pathway. Taken together, the results of the present study suggest that METTL1 acts as an oncogene in LUAD, thus may be a potential prognostic predictor and therapeutic target for LUAD.Tumor mutation burden (TMB) is an independent indicator used to select patients sensitive to immunotherapy. The present study aimed to investigate the clinicopathological and molecular characteristics of patients with hypermutant lung cancer to identify an economical, simple and complementary method for predicting TMB and immunotherapy responses. In total, 1,000 patients with lung cancer were randomly selected, and their samples were submitted to next-generation sequencing, with their TMB status reviewed. The threshold of hypermutation was set to 17.24 mutations (muts)/Mb. The proportion of smokers was higher in the hypermutant cohort (n=67) compared with in the non-hypermutant cohort (n=933; 85.1 vs. 46.6%; P less then 0.0001). Compared with in the non-hypermutant cohort, the proportion of squamous cell carcinoma cases and small cell lung cancer cases was higher in the hypermutant cohort (22.4 vs. 13.1% and 6.0 vs. 2.6%, respectively). In addition, compared with in the non-hypermutant cohort, mutations in thatients sensitive to immunotherapy.Glioblastoma multiforme (GBM) is the most common type of malignant brain tumor. GBM is currently treated with temozolomide (TMZ), although patients often exhibit resistance to this agent. Although several mechanisms underlying the resistance of GBM to TMZ have been identified, the combination of these mechanisms is not sufficient to fully account for this phenomenon. Our previous study demonstrated that knocking down the Forkhead box protein O3a (FoxO3a) gene, a member of the FoxO subfamily of transcription factors, resulted in glioma cell sensitization to TMZ, accompanied by reduced levels of nuclear β-catenin. The aim of the present study was to specify how FoxO3a and β-catenin are implicated in glioma cell TMZ resistance. Using the U87 and U251 parental cell lines (also designated as sensitive cell lines) and corresponding resistant cell lines (U87-TR and U251-TR, generated by repeated TMZ treatments), coupled with a combined knockdown/overexpression strategy, it was revealed that FoxO3a or β-catenin overe the development of TMZ resistance in GBM.The role of microRNA (miR)-1301-3p has been investigated in breast cancer and colorectal cancer. Dysregulation of miR-1301-3p expression in non-small cell lung cancer (NSCLC) is speculated to be associated with tumor progression, which was systemically investigated in the present study. Reverse transcription-quantitative PCR analysis was performed to detect miR-1301-3p expression in 124 paired tissue samples and cultured cell lines. The results demonstrated that miR-1301-3p expression was regulated by transfection with miR-1301-3p mimic or inhibitor, and the proliferation, migration and invasion of the transfected cells were assessed via the Cell Counting Kit-8 and Transwell assays. In addition, miR-1301-3p expression was significantly upregulated in NSCLC tissues and cells compared with normal tissues and normal cells, respectively. Notably, upregulated miR-1301-3p expression in NSCLC tissues was significantly associated with the TNM stage, lymph node metastasis and poor prognosis of patients with NSCLC. Furthermore, upregulated miR-1301-3p expression in NSCLC cells promoted cell proliferation, migration and invasion, the effects of which were reversed following miR-1301-3p knockdown. Thy-1 was identified as a direct target of miR-1301-3p, which serves as a tumor promoter in the progression of NSCLC. Taken together, the results of the present study suggest that upregulated miR-1301-3p expression in NSCLC acts as an independent prognostic factor and a tumor promoter by targeting thy-1, thus provides a potential therapeutic target for NSCLC.Pancreatic ductal adenocarcinoma (PDAC) is the most common tumor subtype of pancreatic cancer, which exhibits poor patient prognosis due to the lack of effective biomarkers in the diagnosis and treatment. The present study aimed to identify the potential biomarkers of PDAC carcinogenesis and progression using three microarray datasets, GSE15471, GSE16515 and GSE28735, which were downloaded from the Gene Expression Omnibus database. The datasets were analyzed to screen out differentially expressed genes (DEGs) in PDAC tissues and adjacent normal tissues. A total of 143 DEGs were identified, including 132 upregulated genes and 11 downregulated genes. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes functional and signaling pathway enrichment analyses were performed on the DEGs, and the Search Tool for the Retrieval of Interacting Genes/Proteins database was used to construct a protein-protein interaction network. The main functions of DEGs include extracellular matrix degradation, and regulation of mattreatment of patients with PDAC.Despite recent advancements in the therapeutic landscape of acute myeloid leukemia (AML), the prognosis of patients remains poor. Immune check point inhibitors have been investigated in hematological malignancies, including AML; however, the role of T-cell immunoglobulin and mucin domain 3 (TIM-3) in AML has not yet been fully elucidated. Thus, the present study aimed to investigate TIM-3 gene expression in patients with AML and determine its associations with prognostic variables and clinical outcome. A total of 60 patients newly diagnosed with AML and 15 healthy matching individuals were recruited in the present study, and reverse transcription-quantitative PCR analysis was performed to detect TIM-3 expression. The results demonstrated that TIM-3 expression was significantly upregulated in patients with AML compared with that in healthy individuals (P less then 0.001). In addition, patients with extramedullary disease (EMD) exhibited significantly lower median TIM-3 expression levels compared with those without EMD (P=0.
