Esophageal cancer (EC) is a highly complex disease with high incidence and mortality rates. Recent studies have shown that miRNAs play critical roles in diverse biological processes including oncogenesis, and we previously reported significantly increased expression of tissue and circulating miR-144 in EC. This study evaluates the functional significance of miR-144 in esophageal squamous cell carcinoma. Herein, we analysed the role of miR-144 in ESCC by silencing it in KYSE-410 cells, and followed this with cell cycle analysis and the following assays; MTT, annexin, colony formation, scratch and matrigel invasion assay...

The development of colorectal cancer is affected by many factors, especially the intestinal microbiota. However, precise knowledge of bacterial communities associated with the mucosa in various parts of the colon is limited. Herein, we applied the gentamicin protection assay and detected the presence of intracellular bacteria in colorectal biopsies from Slovak patients with colorectal adenoma and carcinoma, and we compared this with healthy controls. The ENTEROtest 24 and MALDI-TOF mass spectrometry identified the cultivated bacteria and results revealed the presence of intracellularly localized Escherichia coli, Proteus mirabilis and Proteus vulgaris in patients with colorectal adenomas and carcinomas...

Lung cancer remains the most common cause of tumor-related death worldwide. Recent studies have revealed that long non-coding RNAs (lncRNAs) are involved in the development of various cancers, including lung cancer. This study aimed to investigate the effect and the molecular basis of lncRNA PICART1 on lung cancer. We first assessed the PICART1 expression in lung cancer in vitro and vivo by qRT-PCR. Then the expression of PICART1 in SPC-A-1 and NCI-H1975 cell lines was inhibited and overexpressed by transient transfections...

Cancer is the main leading cause of death in the world, although it has been made noteworthy advances in cancer research in the past decades. Early detection of cancer is extremely important in improving the chances of successful therapy. Thus, it is urgently needed to make further efforts to explore novel tumor markers for treatment.Nicotinamide N-methyltransferase (NNMT) is a cytosolic enzyme which catalyzes the N-methylation of nicotinamide to form 1-methylnicotinamide (1-MNA), and plays an important role in controlling the intracellular concentration of nicotinamide...

Natural killer (NK) cell-based immunotherapy is promising, as NK cells are in the first line of defense against cancer and capital of lysing tumor cells without pre-stimulation. However, NK cells from multiple myeloma (MM) patients are always deficient in numbers and the expression of certain activating receptors, disabling them in cytotoxicity against the cancer. Therefore, effective strategies to expand NK cells and increase NK cell-mediated cytotoxicity against MM are significant. Here, NK cells were efficiently expanded from peripheral blood mononuclear cells (PBMCs) of newly diagnosed MM patients after co-culture with irradiated K562 cells transfected with 41BBL and membrane-bound interleukin (IL)-15 (K562-mb15-41BBL) in the presence of 200 IU/ml human IL-2...

Colorectal cancer (CRC) exhibits differences in its features depending on the location of the tumor. The role of the circadian system in the carcinogenesis is accepted and many studies report different clock gene expression in tumors compared to healthy tissue, although a little attention is given to the changes in clock genes in tumors arising from various locations across the colon and rectum. The aim of our study was to investigate the expression of the clock genes cry1 and cry2 in human CRC tissue and tissue adjacent to colorectal tumors in a cohort of 64 patients by real time PCR...

The mannose 6-phosphate/insulin-like growth factor 2 receptor (CD222, M6P/IGF2R) is a multifunctional transmembrane type I receptor, mostly localized intracellularly, less on the surface of all types of mammalian cells. It is known both to transport lysosomal enzymes through their mannose 6-phosphate moieties and to internalize extracellular ligands like insulin-like growth factor 2 or plasminogen. CD222 is involved in regulation of cell proliferation, migration, T cell activation, and apoptosis. Soluble CD222 has been found in higher concentrations in sera of liver disease patients...

Many diseases have different pathological backgrounds responsible for abnormal cell behavior and exhibiting altered function and signal transduction. This is especially true for tumors and although changes affecting DNA sequence, irreversible mutations and chromosomal aberrations in gastrointestinal stromal tumors (GISTs) have been widely studied, the importance of reversible epigenetic changes increasingly recognized in many cancers has received insufficient attention in these tumors. Epigenetic mechanisms are part of normal development and gene expression under normal conditions, but malfunction of these processes leads to malignant transformation by disturbing both intra- and intercellular communication...
