Higher Glucose Enhances Breast Cancer Cell Aggressiveness.

Cancer cells overexpress several transcription factors and motor proteins, such as NFkB and kinesin, to accommodate their high energy demand as well as migratory needs via enhanced glycolysis. We hypothesize that high glucose drives cancer progression and cell aggressiveness by decreasing actin expression, increasing NFkB, and kinesin expressions, and by activating Epithelial Mesenchymal Transition (EMT). Using lowly metastatic MCF-7 and highly metastatic MDA-MB231 (MB231) breast cancer cells - highly incid...

The Potential Physiological Role of γ-Tocopherol in Human Health: A Qualitative Review.

Chronic aging-related diseases result in the greatest burden to the health care system, yet there is little agreement on optimal levels of vitamins or the functional significance of many other dietary molecules in disease prevention. This review presents accumulated information regarding the role of γ-tocopherol in the prevention of nitrogen oxide-mediated damage and its impact on aging-related diseases. γ-Tocopherol is ubiquitous in the diet and levels appear to be physiologically regulated such that lev...

Serum Nutritional Markers as Prognostic Factors for Hepatic and Extrahepatic Carcinogenesis in Japanese Patients with Nonalcoholic Fatty Liver Disease.

Serum zinc (Zn) levels and the branched chain amino acid/tyrosine molar ratio (BTR) were reported to decrease with the progression of various chronic liver diseases. We investigated the impact of BTR and Zn on the incidence of malignancies in patients with biopsy-proven nonalcoholic fatty liver disease (NAFLD). A total of 179 Japanese NAFLD patients who underwent liver biopsy were enrolled. Hepatocellular carcinoma (HCC) and extrahepatic malignancies developed in 7 (3.9%) and 10 (5.6%) patients, respectivel...

Pre-Surgical Nutrition Support Reduces the Incidence of Surgical Wound Complications in Oncological Patients.
