Oxidative Stress News and Research

RSS

Oxidative Stress is a condition in which antioxidant levels are lower than normal. Antioxidant levels are usually measured in blood plasma.

Toxic substance acrolein may play role in preventing fibrillation linked to Alzheimer's disease

Scientists from RIKEN in Japan have discovered that acrolein—a toxic substance produced in cells during times of oxidative stress—in fact may play a role in preventing the process of fibrillation, an abnormal clumping of peptides that has been associated with Alzheimer's disease and other neural diseases.

TSRI chemists identify and design potent therapeutic ‘warheads’ for different diseases

In a pair of related studies, chemists from the Florida campus of The Scripps Research Institute (TSRI) have identified and designed dozens of molecular “warheads” that not only can detect a key biomarker of cancer, but also could be developed into a potent new class of drug candidates for a range of diseases.

Low levels of vitamin D, methylation in black teens may increase cancer risk

Low levels of vitamin D in black teens correlates with low activity of a major mechanism for controlling gene expression that may increase their risk of cancer and other disease, researchers report.

New computer algorithm can better characterize functional context of genomic variations in cancer

Cancer is rarely the result of a single mutation in a single gene. Rather, tumors arise from the complex interplay between any number of mutually exclusive abnormal changes in the genome, the combinations of which can be unique to each individual patient.

Scientists discover underlying mechanisms of nerve damage

Recent research by Sandra Rieger, Ph.D., of the MDI Biological Laboratory identifying the underlying mechanisms of peripheral neuropathy, or nerve damage, has raised the prospect that drug therapies can be developed for the treatment of this condition, which causes pain, numbness and/or tingling in the hands and feet. The research was published March 28 in the Proceedings of the National Academy of Sciences.

Increased expression of VEGF-A promotes three common aging-related eye conditions

A Massachusetts General Hospital investigator has found that increased expression of the angiogenic factor VEGF-A promotes three common aging-related eye conditions - both versions of age-related macular degeneration (AMD) and also cataracts - in an animal model.

Novel metabolic pathways help cancer cells thrive under certain conditions

Scientists at the Children's Medical Center Research Institute at UT Southwestern (CRI) have identified a novel metabolic pathway that helps cancer cells thrive in conditions that are lethal to normal cells.

Aged tumor cells in melanoma behave in a different way than younger tumor cells

Cancer risk increases with one's age as accumulated damage to our cells and chronic inflammation occur over time. Now, an international team of scientists led by The Wistar Institute have shown that aged tumor cells in melanoma behave differently than younger tumor cells, according to study results published in the journal Nature.

Tumor suppressor p53 gene twice as likely to be defective in autistic children

A large study by researchers with the UC Davis MIND Institute has found that a gene whose role is to suppress cellular damage from environmental stressors is nearly twice as likely to be defective in children with autism spectrum disorder (ASD), and that the deficit is also present in their fathers.
