A diet rich in high glucoraphanin broccoli interacts with genotype to reduce discordance in plasma metabolite profiles through modulating mitochondrial function

submitted by: Andrew Chapple
Background: Observational and experimental studies suggest that diets rich in cruciferous vegetables and glucosinolates may reduce the risk of cancer and cardiovascular disease (CVD). Objective: We tested the hypothesis that a 12-wk dietary intervention with high-glucoraphanin (HG) broccoli would modify biomarkers of CVD risk and plasma metabolite profiles to a greater extent than interventions with standard broccoli or peas. Design: Subjects were randomly assigned to consume 400 g...

Cancer prevention: what is energy balance?

submitted by: mdanderson
What is energy balance? It may sound like a strange term, but it basically means equalizing the amount of calories you take in with how much you burn through exercise, metabolism and body processes. Since obesity is one of the leading causes of cancer, Carrie Daniel-MacDougall, Ph.D., M.P.H. and Susan Schembre, Ph.D., R.D., both assistant professors in Cancer Prevention and Population Sciences at MD Anderson Cancer Center, study behaviors and biological processes associated with linking...

Deriving rules and assertions from pharmacogenomics knowledge resources in support of patient drug metabolism efficacy...

Full title: Deriving rules and assertions from pharmacogenomics knowledge resources in support of patient drug metabolism efficacy predictions Abstract: Objective Pharmacogenomics evaluations of variability in drug metabolic processes may be useful for making individual drug response predictions. We present an approach to deriving ‘phenotype scores’ based on existing pharmacogenomics knowledge and a patient's genomics data. Pharmacogenomics plays an important role in the bioactivation...

Cytokines and Neutrophins in Neuroprotection

submitted by: alex01
Dr. Michael Spedding published recently a review on the role of cytokines and neurotrophins in disease. Neurotrophins (e.g. BDNF) have beneficial effects on neuronal plasticity and brain metabolism. Inflammatory cytokines (e.g. IL1beta)oppose the effects of neurotrophins. Both, neurotrophins and cytokines are targets for the development of new drugs affecting central nervous system. Brain-derived neurotrophic factor (BDNF) is the main activity-dependent neurotrophic factor. Interleukin 1beta...

AMPA Ligands in Neuroprotection

submitted by: alex01
Michael Spedding (Institute Internatinales Servier, Paris, France) described how neuroprotection can be achieved by either by blockade or by stimulation of AMPA (a-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid) receptors. Low threshold AMPA receptor stimulation leads to the release of BDNF (brain-derived neurotrophic factor) which is neuroprotective. Blockade of AMPA receptors reduces excitotoxicity leading to neuroprotection. BDNF is a major activity-dependent neurotrophic factor...
