Hypoxia News and Research

RSS

Hypoxia is a condition in which there is a decrease in the oxygen supply to a tissue. In cancer treatment, the level of hypoxia in a tumor may help predict the response of the tumor to the treatment.

Study reveals how glioblastomas resist the effects of antiangiogenic drugs

A study led by investigators from Massachusetts General Hospital (MGH) and the University of Cyprus reveals details of a way the dangerous brain tumors called glioblastomas resist the effects of antiangiogenic drugs designed to cut off their blood supply.

Cardiovascular disease risk begins even before birth

Heart disease is the greatest killer in the world today, and it is widely accepted that our genes interact with traditional lifestyle risk factors, such as smoking, obesity and/or a sedentary life to promote an increased risk of cardiovascular disease.

Poor blood oxygenation during sleep predicts chance of heart-related death

Elderly men who experience extended episodes of interrupted breathing while asleep have a high risk of heart problems. Research shows for the first time that poor blood oxygenation is a good indicator of the chance of heart-related death, which cannot be attributed to sleep apnoea alone.

Research finds how Candida albicans adapt to low oxygen levels to cause infection

Scientists from Umeå university have shown how the yeast Candida albicans can modulate and adapt to low oxygen levels in different body niches to cause infection and to harm the host.

Molecular hallmarks of tumor hypoxia across 19 cancer types discovered

Unlike healthy tissues, tumors thrive in low-oxygen environments, often acquiring the ability to resist treatment and spread to other sites in the body. Despite being a well-known cause of therapy resistance and metastasis, the impact of low oxygen, known as hypoxia, on tumor cells is poorly understood.

Scientists discover mutational signatures of tumor hypoxia

Researchers have discovered mutational signatures of tumor hypoxia in 19 cancer types that could be used to identify patients who need higher treatment doses.

Himalayan marmot genome offers clues to high-altitude adaptation

Himalayan marmots can survive at altitudes up to 5,000 meters in the Himalayan regions of India, Nepal, and Pakistan and on the Qinghai-Tibetan Plateau of China, where many of them face extreme cold, little oxygen, and few other resources.

Protecting powerhouse of cells could provide better way to treat acute kidney injury

For the first time, scientists have described the body's natural mechanism for temporarily protecting the powerhouses of kidney cells when injury or disease means they aren't getting enough blood or oxygen.

Scientists restore breathing, forelimb function in animal models of chronic spinal cord injury

Millions of people worldwide are living with chronic spinal cord injuries, with 250,000 to 500,000 new cases each year--most from vehicle crashes or falls.

Researchers show how proteins interact in hypoxic conditions to facilitate mitochondrial fission

During a heart attack the supply of oxygen to heart cells is decreased. This reduced oxygen level, called hypoxia, causes the cell's powerhouses, the mitochondria, to fragment, impairing cell function and leading to heart failure. Until now, few details were known on how this important process occurs.

Study identifies potential therapeutic strategy for patients with clear cell renal cancer

Researchers have provided new insight on the mechanisms behind the development of clear cell Renal Cell Carcinoma (ccRCC), according to new findings published in eLife.

New study shows promise of innovative strategy against HER2-driven lung cancers

The HER2 gene is a well-known driver of breast cancer, where changes in this gene are found in about 1-in-5 cases of the disease. HER2 also contributes to about 3 percent of lung cancers, representing about 6,500 patients per year.

Regular use of party drug GHB associated with brain changes

Scientists have discovered that regular use of the party drug GHB, and especially unconsciousness following GHB use, is associated with brain changes including negative effects on long-term memory, working memory, IQ, and higher levels of stress and anxiety.

NCCN adds COPIKTRA capsules to NCCN Guidelines for follicular lymphoma

Verastem, Inc., focused on developing and commercializing medicines to improve the survival and quality of life of cancer patients, today announced that the National Comprehensive Cancer Network added COPIKTRA (duvelisib) capsules to the Clinical Practice Guidelines in Oncology (NCCN Guidelines) for follicular lymphoma.

Combination approach appears to improve chemotherapy response, boost anti-tumor immunity

Scientists at the University of Toronto's Leslie Dan Faculty of Pharmacy have seen remarkable success combining tumor modulating nanoparticles with doxorubicin to enhance chemotherapy response in pre-clinical model breast cancer.

New nanoplatform technology may reverse drug-resistance in renal cell carcinoma

A research team led by Arun Iyer, Ph.D., assistant professor of pharmaceutical sciences in the Eugene Applebaum College of Pharmacy and Health Sciences at Wayne State University, has developed a nanoplatform technology that works in combination with existing chemotherapeutic drugs that may reverse drug-resistance in renal cell carcinoma.
