Hypoxia News and Research RSS Feed - Hypoxia News and Research

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.
Stiff, hypoxic regions of tumors trigger cancer progression

Stiff, hypoxic regions of tumors trigger cancer progression

When Hippocrates first described cancer around 400 B.C., he referred to the disease's telltale tumors as "karkinos" -- the Greek word for crab. [More]

Eating nitrate-rich vegetables may enhance exercise performance

Nitrate supplementation in conjunction with Sprint Interval Training in low oxygen conditions could enhance sport performance a study has found. [More]
HIF-2 inhibitors could be promising target to combat kidney cancer

HIF-2 inhibitors could be promising target to combat kidney cancer

A new class of drugs called HIF-2 inhibitors is more effective and better tolerated than the standard of care drug sunitinib in treating kidney cancer, researchers with the Kidney Cancer Program at Harold C. Simmons Comprehensive Cancer Center have found. [More]
Could a light-listening photonics device detect skin disease? An interview with Prof. Vasilis Ntziachristos

Could a light-listening photonics device detect skin disease? An interview with Prof. Vasilis Ntziachristos

Detection of malignant skin alterations is currently aided by optical microscopes such as dermoscopes or optical microscopes. While the latter offers high resolution, it comes with a major disadvantage, just like any other purely microscopic method: it only provides a partial view of the skin due to the low penetration depth.

Injecting omega-3 fatty acid reduces brain damage in neonatal mouse model of stroke

Injecting omega-3 fatty acid reduces brain damage in neonatal mouse model of stroke

Researchers from Columbia University Medical Center found that omega-3 fatty acids reduced brain damage in a neonatal mouse model of stroke. [More]
Maintaining proper oxygen supply in tumors could be key factor to stop progression of cancer

Maintaining proper oxygen supply in tumors could be key factor to stop progression of cancer

The lack of oxygen in tumor cells changes the cells' gene expression, thereby contributing to the growth of cancer. [More]
Obstructive sleep apnea and hypoxia linked to progression of NAFLD in obese adolescents

Obstructive sleep apnea and hypoxia linked to progression of NAFLD in obese adolescents

Researchers from the University of Colorado School of Medicine have published a new study showing that sleep apnea worsens non-alcoholic fatty liver disease in obese adolescents. [More]
Philips collaborates with Mayo Clinic to climb Mount Kilimanjaro on research expedition

Philips collaborates with Mayo Clinic to climb Mount Kilimanjaro on research expedition

Royal Philips today announced it will be among the leading organizations collaborating with the Mayo Clinic to climb Mount Kilimanjaro on a research expedition to understand how the body reacts to the rigors of high altitude and how those learnings can be applied to improving human health. [More]
Scientists link malfunctioning molecular pathways to specific heart abnormalities in SCA

Scientists link malfunctioning molecular pathways to specific heart abnormalities in SCA

Patients with sickle cell anemia (SCA) develop heart complications and nearly a quarter die a sudden death. Now, researchers have linked malfunctioning molecular pathways to specific heart anomalies in SCA that result from progressive fibrosis and result in sudden death. [More]
Wistar scientists discover novel mechanism that helps tumors adapt to hypoxia

Wistar scientists discover novel mechanism that helps tumors adapt to hypoxia

One of the many reasons tumors are so difficult to treat is that they are able to adapt whenever they are exposed to unfavorable conditions. [More]
Sleep-disordered breathing promotes progression of pediatric NAFLD to NASH

Sleep-disordered breathing promotes progression of pediatric NAFLD to NASH

Studies have shown that obstructive sleep apnea and low nighttime oxygen, which result in oxidative stress, are associated with the progression of non-alcoholic fatty liver disease (NAFLD) in adults. [More]
Scientists measure eye pressure of sleeping patients to find link between OSAS and glaucoma

Scientists measure eye pressure of sleeping patients to find link between OSAS and glaucoma

Scientists at Hokkaido University have successfully measured the eye pressure of sleeping patients with obstructive sleep apnea syndrome for the first time, finding an unexpected correlation with glaucoma. [More]
Breakthrough research shows cellular stress could be key to variety of birth defects

Breakthrough research shows cellular stress could be key to variety of birth defects

For the first time, scientists believe they've discovered a cause of multiple types of birth defects triggered by environmental stresses. [More]
Identifying new pathway of EZH2 gene may lead to targeted therapies for aggressive breast cancer

Identifying new pathway of EZH2 gene may lead to targeted therapies for aggressive breast cancer

Scientists from A*STAR's Genome Institute of Singapore and the Cancer Science Institute of Singapore at the National University of Singapore came together to understand how EZH2, a cancer-promoting gene which is known to be involved in many types of cancers, is activated in breast cancer and lymphomas. [More]
Physicians may need to allow sufficient time before predicting outcomes in comatose cardiac arrest patients

Physicians may need to allow sufficient time before predicting outcomes in comatose cardiac arrest patients

Physicians may be drawing conclusions too soon about survival outcomes of patients who suffered a cardiac arrest outside the hospital. [More]
Mice study shows influence of dad's obesity on daughter’s body weight and breast cancer risk

Mice study shows influence of dad's obesity on daughter’s body weight and breast cancer risk

Obese male mice and normal weight female mice produce female pups that are overweight at birth through childhood, and have delayed development of their breast tissue as well as increased rates of breast cancer. [More]
Breast cancer cells use new signaling pathway to cope with lack of oxygen levels inside tumors

Breast cancer cells use new signaling pathway to cope with lack of oxygen levels inside tumors

Researchers have identified a new signaling pathway that helps cancer cells cope with the lack of oxygen found inside tumors. These are the results of a study published in Nature Cell Biology on June 20, and led by researchers at NYU Langone Medical Center and its Laura and Isaac Perlmutter Cancer Center, Princess Margaret Cancer Center, the University of Toronto, Harvard Medical School and Oxford University.

New research helps better understand role of TIP60 in allowing tumors to survive in low-oxygen environments

In summer 2011, University of Colorado Cancer Center investigators Joaquín Espinosa, PhD, and Matthew Galbraith, PhD, taught a summer symposium on gene expression at Cold Spring Harbor Laboratory in Long Island, New York. [More]
New technique may help replace brain cells, restore memory

New technique may help replace brain cells, restore memory

Although brains—even adult brains—are far more malleable than we used to think, they are eventually subject to age-related illnesses, like dementia, and loss of cognitive function. [More]
