Cancer cells are highly dependent on glycolysis. Our aim was to determine if switching metabolism from glycolysis towards mitochondrial respiration would reduce growth preferentially in colorectal cancer cells over normal cells, and to examine the underlying mechanisms. »

Extracellular matrix metalloproteinase inducer (EMMPRIN) has been shown to promote tumor invasion and metastasis via stimulating matrix metalloproteinase synthesis in neighboring fibroblasts, to enhance angiogenesis via vascular endothelial growth factor, to induce chemoresistant tumor cells via the production of hyaluronan, and to confer resistance of cancer cells to anoikis through inhibition of Bim. The purpose of this study was to investigate the expression of EMMPRIN in human primary bladder cancer and to evaluate its prognostic value. »

Decursin, a pyranocoumarin isolated from the Korean Angelica gigas root, has demonstrated anti-cancer properties. In the present study, we found that decursin inhibited cell viability in cultured human urinary bladder cancer 235J cells and colon cancer HCT116 cells. »

Thyroid cancer is the second most common malignancy following breast cancer in Arab females. Thioredoxin (TRX) is a small multi-functional redox protein with both intracellular and extracellular functions. The protein exists in either a reduced form (thioredoxin-SH2) or an oxidized form (thioredoxin-S2). »

For Hepatocellular Carcinoma (HCC) treated with hepatectomy, the extent of the resection margin remains controversial and data available on its effect on early tumor recurrence are very few and contradictory. The purpose of this study was to compare the impact of the type of resection (anatomic versus non-anatomic) on early intra-hepatic HCC recurrence in patients with solitary HCC and preserved liver function. »

Since malignant cells often have a high demand for iron, we hypothesize that breast cancer cells may alter the expression of iron transporter genes including iron importers [transferrin receptor (TFRC) and solute carrier family 11 (proton-coupled divalent metal ion transporters), member 2 (SLC11A2)] and the iron exporter SLC40A1 (ferroportin), and additionally that the growth of breast cancer can be inhibited by manipulating iron transporter gene expression. »

MicroRNAs (miRNAs) are small RNA molecules that modulate gene expression and which have been implicated in cancer. We evaluated whether five candidate predictive miRNAs, derived from a pilot study in which 249 miRNAs were assayed, were associated with clinical benefit of tamoxifen therapy in advanced breast cancer. »

Studies conducted in animal model of infectious diseases or H-Y antigen model suggest a crucial role for CD4+ T cells in providing help for CD8+ T-cell memory responses. This concept suggests that inclusion of T helper epitopes in vaccine formulation will result in improved CD8+ T-cell responses. »
