Long non-coding RNAs (lncRNAs) have multiple functions in gene regulation and during cellular processes. However, the functional roles of lncRNAs in colorectal cancer (CRC) have not yet been well understood. In our previous study, we demonstrated that sTLR4/MD-2 complex can inhibit CRC in vitro and in vivo by targeting LPS. Therefore, the aim of the present study is to investigate the expression of lncRNA H19 in CRC and to evaluate its effect on the inhibition of sTLR4/MD-2 complex. The expression of H19 is measured in 63 CRC tumor tissues and adjacent normal tissues by quantitative real-time PCR (qRT-PCR)...

The immune status of tumor microenvironment in gastric cancer is poorly understood, which limits the development of novel strategies in this field. Sphingosine-1-phosphate (S1P) acts as an immune modulator, but the role of S1P in gastric cancer is elusive. Here, we aim to investigate S1P receptor 1 (S1P1)-mediated effect of S1P in gastric cancer. We generated a xenograft mouse model and used SEW-2871, a S1P1 specific agonist to activate S1P1 signaling. Tumor-infiltrating lymphocytes (TILs) were isolated and analyzed using flow cytometry...

BACKGROUND: Vimentin belongs to an intermediate filament (IF) family of proteins, mainly present in mesenchymal cells and has a crucial role in maintaining cellular integrity. Vimentin can induce epithelial to mesenchymal transition, and thus increase migration and invasion capacity of the cells. It has been shown to be a useful and reliable diagnostic and prognostic marker in several cancers including colon cancers, breast and hepatocellular cancers. Recent studies suggest that it may have a role in distant metastasis of non-small cell lung cancer (NSCLC) accounting for poor survival [1]...

Urothelial carcinoma (UC) carcinogenesis has been hypothesized to occur through epigenetic repression of tumor-suppressor genes (TSGs). By quantitative real-time polymerase chain reaction array, we found that one potential TSG, angiopoietin-like 4 (ANGPTL4), was expressed at very low levels in all bladder cancer cell lines we examined. Previous studies had demonstrated that ANGPTL4 is highly expressed in some cancers, but downregulated, by DNA methylation, in others. Consequently, owing to these seemingly conflicting functions in distinct cancers, the precise role of ANGPTL4 in the etiology of UC remains unclear...

Hepatocellular carcinoma (HCC) represents the fifth and ninth cause of mortality among male and female cancer patients, respectively and typically arises on a background of a cirrhotic liver. HCC develops in a multi-step process, often encompassing chronic liver injury, steatosis and cirrhosis eventually leading to the malignant transformation of hepatocytes. Aberrant expression of the class I homeobox gene family (HOX), a group of genes crucial in embryogenesis, has been reported in a variety of malignancies including solid tumors...

Angiogenesis (the growth of new blood vessels) is essential in most of the body's physiological processes, such as in the normal functioning of the endometrium during and after the menstrual cycle. Vascular endothelial growth factor (VEGF) and matrix metalloproteinase (MMP) are the mostly expressed angiogenic factors, especially, during the process of endometrial degeneration and remodeling. In carcinogenesis, tumor hypoxia-induced factors, through the process of "angiogenic switch", stimulate the production of angiogenic factors, particularly VEGF and MMP...

Fucosylation is a glycan modification critically involved in cancer and inflammation. Although potent fucosylation inhibitors are useful for basic and clinical research, only a few inhibitors have been developed. Here, we focus on a fucose analog with an alkyne group, 6-alkynyl-fucose (6-Alk-Fuc), which is used widely as a detection probe for fucosylated glycans, but is also suggested for use as a fucosylation inhibitor. Our glycan analysis using lectin and mass spectrometry demonstrated that 6-Alk-Fuc is a potent and general inhibitor of cellular fucosylation, with much higher potency than the existing inhibitor, 2-fluoro-fucose (2-F-Fuc)...

The CXCR4/CXCR7/CXCL12 chemokine axis plays important roles in the migration of tumor cells during cancer development by modulating site-specific distant metastasis including to regional lymph nodes. We investigated the correlation of these chemokine expressions to prognosis in lymph-node-positive non-small-cell lung cancer (NSCLC) patients. A total of 140 surgically resected specimens of primary site (PS) and metastatic lymph nodes (MLN) of NSCLC involving hilar and/or mediastinal lymph nodes (N1-2) were collected...

Hepatocelluar carcinoma (HCC) is one of the most frequently diagnosed cancers worldwide and among the leading causes of cancer-related death. Although deregulation of microRNAs has been frequently described in HCC, imperfection is known about the precise molecular mechanisms by which microRNAs modulate the process of tumorogenesis and behavior of cancer cells. In this study, we demonstrated that miR-758-3p could suppress cell proliferation, migration and invasion in hepatocellular carcinoma cells. We screened and identified two novel miR-758-3p targets, MDM2 and mTOR...

The treatment of chronic pain remains a challenge for clinicians worldwide, independent of its pathogenesis. It motivates several studies attempting to discover strategies to treat the disease. The in silico analysis using molecular docking approach demonstrated that the phthalimide N-(4methyl-phenyl)-4-methylphthalimide (MPMPH-1) presented high affinity to adenylyl-cyclase enzyme (AC). It also prominently reduced the mechanical hypersensitivity of mice challenged by Forskolin, an AC activator. This effect lasted for up to 48h after Forskolin injection, presenting activity longer than MDL-12330A (AC inhibitor)...

Catalpol, an iridoid glucoside compound, is reported to possess diverse pharmacological actions. However, its effects on osteosarcoma are little to be known. In the present study, we showed that catalpol could strongly suppress osteosarcoma progression. Catalpol dose-dependently reduced the cancer cell viability. The migration of osteosarcoma cells was also consistently suppressed by catalpol treatment using the wound healing and transwell migration analysis. Catalpol reduced the expressions of Kras, receptor for activated C-kinase 1(RACK1) and matrix metalloproteinase (MMP)-2 in a dose-dependent manner, revealing the blockage of migration...

The tumor suppressor p53 and its family members, p63 and p73, play a pivotal role in the cell fate determination in response to diverse upstream signals. As transcription factors, p53 family proteins regulate a number of genes that are involved in cell-cycle arrest, apoptosis, senescence, and maintenance of genomic stability. Recent studies revealed that p53 family proteins are important for the regulation of cell invasion and migration. Microarray analysis showed that breast cancer metastasis-suppressor 1- like (BRMS1L) is upregulated by p53 family proteins, specifically p53, TAp63γ, and TAp73β...
