Quercetin, a widely distributed bioflavonoid, has been shown to induce growth inhibition in certain cancer cell types. In the present study we have pursued the mechanism of growth inhibition in MCF-7 human breast cancer cells. Quercetin treatment resulted in the accumulation of cells specifically at G2/M phase of the cell cycle. Mitotic index measured by(More)
Neuronal intranuclear inclusions are found in the brains of patients with Huntington's disease and form from the polyglutamine-expanded N-terminal region of mutant huntingtin. To explore the properties of inclusions and their involvement in cell death, mouse clonal striatal cells were transiently transfected with truncated and full-length human wild-type(More)
BACKGROUND A phase II study was conducted to assess the efficacy and tolerability of combination therapy with capecitabine and cisplatin in patients with advanced gastric cancer. PATIENTS AND METHODS Patients with previously untreated metastatic or unresectable measurable gastric adenocarcinoma received oral capecitabine 1250 mg/m(2) twice daily, days(More)
BACKGROUND Only a few clinical trials have been conducted in patients with advanced pancreatic cancer after failure of first-line gemcitabine-based chemotherapy. Therefore, there is no current consensus on the treatment of these patients. We conducted a randomised phase II study of the modified FOLFIRI.3 (mFOLFIRI.3; a regimen combining 5-fluorouracil(More)
AIMS There are few studies reporting survival or recurrence patterns in colorectal cancer patients with inferior mesenteric lymph node metastasis (IMLN+). The present study evaluated the prognostic significance of patients being IMLN+ or IMLN- in colorectal cancer. METHODS Survival, recurrence pattern and treatment protocols were compared between 63 IMLN+(More)
OBJECTIVE Osteonecrosis (ON) of the femoral head frequently leads to progressive collapse of the femoral head followed by degenerative arthritis of the hip joint. Oxidative stress, which has been implicated in many pathological conditions, including vascular injury, recently has been suggested to play a part in the development of ON. Catalase (CAT) is a(More)
The expression of hypoxia-inducible factor-1 (HIF-1) correlates with poor clinical outcomes and confers resistance to the apoptosis of the tumor cells that are exposed to hypoxia. Presently, the mechanism underlying this phenomenon is poorly understood. In this study we provide evidence that transglutaminase 2 (TG2), an enzyme that catalyses protein(More)
Intradermal vaccination via gene gun efficiently delivers DNA vaccines into dendritic cells (DCs) of the skin, resulting in the activation and priming of antigen-specific T cells in vivo. In the context of DNA vaccines, we previously used the gene gun approach to test several intracellular targeting strategies that are able to route a model antigen, such as(More)
DNA-based alphaviral RNA replicon vectors, also called suicidal DNA vectors, alleviate the concerns of integration or transformation related to conventional DNA vectors since suicidal DNA vectors eventually cause apoptosis of transfected cells. However, the expression of inserted genes in these vectors is transient and the potency of suicidal DNA vaccines(More)
OBJECTIVE To examine the association between socio-economic status (SES) and liver cancer mortality among Korean men. STUDY DESIGN Prospective cohort study METHODS Data were acquired from a large, prospective cohort study that included 548,530 civil service workers aged 30-59 years who had undergone health examination in 1998 provided by the Korean(More)
