Abstract In the present study, we investigated the synergistic effects of targeted methotrexate-selenium nanostructure containing Myc decoy oligodeoxynucleotides along with X-irradiation exposure as a combination therapy on LNCaP prostate cancer cells. Myc decoy ODNs were designed based on the promoter of Bcl-2 gene and analyzed by molecular docking and molecular dynamics assays. ODNs were loaded on the synthesized Se@BSA@Chi-MTX nanostructure. The physicochemical characteristics of nanostructures were determined by FTIR, DLS, UV-vis, TEM, EDX, in vitro release, and hemolysis tests. Subsequently, the cytotoxicity properties of them with and without X-irradiation were investigated by uptake, MTT, cell cycle, apoptosis, and scratch assays on… More > Graphic Abstract

Abstract Lung cancer has the highest mortality rate among all cancers, in part because it readily metastasizes. The tumor microenvironment, comprising blood vessels, fibroblasts, immune cells, and macrophages [including tumor-associated macrophages (TAMs)], is closely related to cancer cell growth, migration, and invasion. TAMs secrete several cytokines, including interleukin (IL)-1β, which participate in cancer migration and invasion. p21-activated kinase 1 (PAK1), an important signaling molecule, induces cell migration and invasion in several carcinomas. Tonicity-responsive enhancer-binding protein (TonEBP) is also known to participate in cancer cell growth, migration, and invasion. However, the mechanisms by which it increases lung cancer migration remain unclear. Therefore,… More > Graphic Abstract

Abstract Background: Homeobox B8 (HOXB8), a member of HOX family, plays a key role in the development of colorectal cancer (CRC). However, the function of HOXB8 in oxaliplatin (OXA) resistance in CRC is still unclear. This study investigated the role and precise molecular mechanism of HOXB8 in OXA-resistant CRC cells. Methods: The cell viability was measured by the 3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolium bromide (MTT) assay, and the colony forming ability was determined by colony formation assay. The silencing RNA (siRNA) approach was used to knockdown HOXB8 in CRC cells while the lentiviral transfection system was used to establish stable HOXB8 overexpressing CRC… More >

Abstract Non-small cell lung cancer (NSCLC) is a malignant tumor with high incidence worldwide. Triptolide (TP), extracted from Tripterygium wilfordii Hook F, exhibits potent broad-spectrum antitumor activity. Although some mechanisms through which TP inhibits NSCLC are well understood, those that involve ribosomal proteins remain yet to be understood. In this study, the transcriptome and proteome were integrated and analyzed. Our data indicated ribosomal protein L4 (RPL4) to be a core hub protein in the protein-protein interaction network. RPL4 is overexpressed in NSCLC tissues and cells. Transfection with siRPL4 or TP treatment alone arrested the cell cycle in the G1 phase, induced… More > Graphic Abstract

Abstract Introduction: Sulfatase 2 (SULF2), an endogenous extracellular sulfatase, can remove 6-O-sulfate groups of glucosamine residues from heparan sulfate (HS) chains to modulate the Wnt/β-catenin signaling pathway, which plays an important role in both liver carcinogenesis and embryogenesis. Side population (SP) cells are widely identified as stem-like cancer cells and are closely related to carcinoma metastasis, recurrence, and poor patient prognosis. However, the roles of SULF2 in SP cells of hepatomas are unclear, and the underlying mechanism is undefined. Objectives: This study aimed to compare the heterogeneity between SP cells and non-side population (NSP) cells derived from three different liver cancer… More > Graphic Abstract

Abstract Invasion and metastasis are important hallmarks of breast cancer and are the leading cause of patient mortality. Triple-negative breast cancer (TNBC) is an aggressive type of breast cancer characterized by a poor prognosis and a lack of effective targeted therapies. The present study investigated the inhibitory effect of a novel FTY720 derivative on the invasive phenotype of TNBC cells. Here, we showed that a novel compound with an isoxazole ring, 4-(3-Decylisoxazol-5-yl)-1-hydroxy-2-(hydroxymethyl)butan-2-aminium chloride (CM2-II-173), significantly inhibited invasiveness of MDA-MB-231 TNBC cells. Expression of matrix metalloproteinase (MMP)-9 and invasiveness of MCF10A normal breast cells induced by sphingosine-1-phosphate (S1P) were reduced by CM2-II-173… More >

Abstract Background: Colorectal cancer (CRC) is one of the most common malignancies. Early diagnosis is the key to effective treatment of CRC. Since microRNAs (miRNAs) can be used as biomarkers of CRC, the objective of this work was to examine the effect of miR-520f-3p, which targets YAP1 (Yes-associated protein 1), on the ability of CRC cells to proliferate, invade, migrate, and undergo epithelial-mesenchymal transition (EMT). Methods: A miR-520f-3p mimic was used to overexpress miR-520f-3p in HT29 cells. To establish the tumor-bearing mouse model, transfected HT29 cells were subcutaneously implanted into BALB/c-nu nude mice, and YAP1 and miR-520f-3p levels were determined using… More > Graphic Abstract

Abstract Backgorund: Fruits and seed extracts of Annona montana have significant cytotoxic potential in several cancer cells. This study evaluates the effect of A. montana leaves hexane extract on several signaling cascades and gene expression in metastatic breast cancer cells upon insulin-like growth factor-1 (IGF-1) stimulation. Methods: MTT assay was performed to determine the proliferation of cancer cells. Propidium iodide staining and flow cytometry analysis of Annexin V binding was utilized to measure the progression of the cell cycle and the induction of apoptosis. Protein expression and phosphorylation were determined by western blotting analysis to examine the underlying cellular mechanism triggered… More >

Abstract Fos-related antigen 1 (Fra-1) is a nuclear transcription factor that regulates cell growth, differentiation, and apoptosis. It is involved in the proliferation, invasion, apoptosis and epithelial mesenchymal transformation of malignant tumor cells. Fra-1 is highly expressed in gastric cancer (GC), affects the cycle distribution and apoptosis of GC cells, and participates in GC occurrence and development. However, the detailed mechanism of Fra-1 in GC is unclear, such as the identification of Fra-1-interacting proteins and their role in GC pathogenesis. In this study, we identified tyrosine 3-monooxygenase/tryptophan 5-monooxygenase activation protein eta (YWHAH) as a Fra-1-interacting protein in GC cells using co-immunoprecipitation… More >

Abstract Background: This study was designed to investigate the roles of RASAL2 in cervical cancer (CC). Methods: Fifty-four CC tissues and 33 adjacent tissues were obtained from CC patients admitted to our hospital between March 2012 and June 2014. Real-time polymerase chain reaction and western blotting were performed to analyze the expression of RASAL2 mRNA and protein in these tissues, CC cell lines, and normal cervical cells. Over-expression and silencing of RASAL2 were induced after transfection, and the migration, invasion, and proliferation of the CC cell lines were examined. Results: RASAL2 mRNA and protein expressions were significantly down-regulated in CC tissues… More >
