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.

Fluorescent bacteria enable real-time tumor visualization during surgery

Accurate removal of tumors is the most critical aspect of cancer surgery, yet it remains a significant challenge in clinical practice.

New insights into brain fueling could lead to treatments for stroke, neurodegeneration

A new Yale study has revealed that neurons - the energy-hungry cells that connect and direct activity in the brain - are equipped with "backup batteries" that kick in to keep the brain running during periods of metabolic stress.

Uncovering a protective RNA molecule in kidney stress and disease

Cells contain helper molecules called transfer RNAs (tRNAs), which carry building blocks (amino acids) to make proteins.

How five months in Tibet changed the heart and lungs of Beijing workers

Long-term exposure to very high altitude significantly reduces cardiopulmonary function in healthy adults from lowland regions, as shown by declines in aerobic capacity and efficiency after five months in Lhasa, China.

Mapping how major organs communicate during physiological stress in humans

How major organs work together to manage extreme physiological stresses such as lack of oxygen and sleep has been mapped for the first time by researchers from UCL and the University of Portsmouth.

Blood flow restriction can match gym gains without joint strain

A clinical trial compares high-intensity resistance training and blood flow restriction methods, revealing effective alternatives for muscle strength gains.

Reversing immune fatigue offers new hope for cancer treatment

CD8⁺ T cells are the immune system's frontline warriors, charged with detecting and eliminating cancer cells. But in the hostile and chronic environment of tumors, these cells often falter.

Study provides a molecular snapshot of Tanshi constitution's immunological landscape

The study aims to uncover the immunological basis of Tanshi (phlegm-dampness) constitution—a subhealth type in traditional Chinese medicine (TCM)—using single-cell RNA sequencing (scRNA-seq) of peripheral blood mononuclear cells (PBMCs).

Caltech researchers develop safer and smarter breast imaging technique

A Caltech-led team has developed a safe, effective, and painless breast imaging technique that incorporates machine learning to help differentiate between suspicious and healthy tissue.

Targeting mitochondrial dynamics to combat breast cancer metastasis

Breast cancer, particularly triple-negative breast cancer (TNBC), remains a leading cause of cancer-related mortality due to its aggressive nature and limited therapeutic targets.

Targeting the tumor microenvironment to improve osteosarcoma outcomes

The complex tumor microenvironment (TME) in osteosarcoma is emerging as a critical factor in disease progression and treatment resistance.

Study shows polar winter challenges men’s muscle mass but not hormone levels

Researchers tracked testosterone, cortisol, and body composition in 23 men overwintering at Concordia Station, Antarctica. Despite extreme polar conditions, hormone levels remained stable, though nearly half the crew experienced significant muscle loss.

Targeting IGF2BP1 offers a new approach to cancer therapy

The RNA-binding protein IGF2BP1 has emerged as a key regulator of cancer hallmarks, influencing tumor proliferation, metastasis, immune evasion, and resistance to cell death.

New hypothesis links caffeine to lower risk of sudden infant death syndrome

After decades of stalled national progress in reducing the rate of Sudden Unexpected Infant Death (SUID), a category of infant mortality that includes sudden infant death syndrome (SIDS), researchers at Rutgers Health have proposed an unexpected solution: Caffeine might protect babies by preventing dangerous drops in oxygen that may trigger deaths.

Alcohol and cabin pressure may harm heart health during flights

The combination of alcohol plus cabin pressure at cruising altitude may threaten sleeping plane passengers' heart health, particularly on long haul flights, suggests the first study of its kind, published online in the respiratory journal Thorax.

Early heart ultrasound may predict birth complications in babies

An echocardiography of the baby's little heart soon after the onset of labour can predict the outcome of the birth and in particular whether the baby will adequately tolerate the contractions or will be more likely to go into distress, necessitating a caesarean section or an operative delivery.

Aging increases brain vulnerability to mild hypoxia and blood-brain barrier disruption

A new research paper was published in Aging (Aging-US) on May 1, 2025, as the cover of Volume 17, Issue 5, titled "Defining the hypoxic thresholds that trigger blood-brain barrier disruption: the effect of age."
