Study identifies a switch in cells that may help to kill tumors with heat

Research at Bangor University has identified a switch in cells that may help to kill tumors with heat. Prostate cancer and other localized tumors can be effectively treated by a combination of heat and an anti-cancer drug that damages the genes. Behind this novel therapy is the enigmatic ability of heat to switch off essential survival mechanisms in human cells. Although thermotherapy is now more widely used, the underlying principles are still unclear.

Researchers develop and test new prostate cancer screening method

Researchers have successfully developed and tested a new prostate cancer screening method that uses the combined power of a novel drug therapy and changes in PSA levels over time to identify men with a high PSA who are more likely to have aggressive prostate cancer despite negative biopsies.

Pathologist identifies HPV DNA fragments in post-mortem samples after Gardasil vaccination

According to Norma Erickson, President of SaneVax Inc., testimony provided for a coroner's inquest into the death of Jasmine Renata in New Zealand by Dr. Sin Hang Lee, a pathologist on the medical staff at Connecticut's Milford Hospital, revealed the discovery of HPV DNA fragments in post-mortem samples 6 months after Gardasil vaccination.

Lung cancer patients can be screened for ALK-inhibitor suitability

Anaplastic lymphoma kinase gene status in patients with lung adenocarcinoma can be determined non-invasively using circulating tumor cells, research shows.

WSU researchers to test novel hypothesis that cardiolipin deficiency leads to disruption of TCA cycle

Barth Syndrome (BTHS) is a rare and serious genetic disorder that primarily affects males and is passed from mother to son; women who are carriers do not show symptoms of the disorder. Fifty percent of children born to a mother who is a carrier will inherit the defective gene, and all daughters born to an affected man will be carriers. BTHS is caused by a mutation in the tafazzin gene that results in decreased production of cardiolipin, an essential lipid for energy metabolism.

Study reports new potential NOX inhibitor therapy for liver fibrosis

A study published in the online journal Hepatology reports a potential new NADPH oxidase (NOX) inhibitor therapy for liver fibrosis, a scarring process associated with chronic liver disease that can lead to loss of liver function.

Studies identify genetic mutations that play important roles in startle disease

Two studies published in the Journal of Biological Chemistry identify genetic mutations that play important roles in the condition commonly referred to as startle disease. Startle disease is characterized by an exaggerated response to noise and touch, which can interfere with breathing, cause catastrophic falls and even result in death.

Variations in RORA gene can lead to post-traumatic stress disorder

Investigators at Boston University School of Medicine (BUSM) and Veterans Affairs (VA) Boston Healthcare System have identified a new gene linked to post-traumatic stress disorder (PTSD).

New class of drugs reduces adverse effects of cellular damage from cancer chemotherapy

Chemotherapy kills tumor cells, but it also wreaks havoc on the rest of the body. A team of researchers led by Igor Roninson of the South Carolina College of Pharmacy just reported the discovery of a new class of drugs that reduces the adverse effects of cellular damage from chemotherapy.

Leptin polymorphism combinations influence BMI in Chinese

The presence of genetic variants in both the leptin gene and the gene for its receptor may predispose Chinese individuals to obesity, report researchers.

Schizophrenia may be linked to immune function

New Australian research shows that the brains of people with schizophrenia may be under attack by the immune system, providing the strongest evidence to date of a link between immune function and schizophrenia.

Researchers discover genetic cause of type VII mucopolysaccharidosis in Brazilian Terriers

The genetics research group led by Professor Hannes Lohi, based at the University of Helsinki and the Folkh-lsan Research Center, has, in collaboration with Adjunct Professor Kirsi Sainio's research group, discovered the cause of a life-threatening skeletal disorder affecting Brazilian Terriers. The disease is caused by a mutation in the GUSB gene.

Children of U.S.-born Latina women more likely to develop retinoblastoma

In a large epidemiologic study, researchers at UCLA's Jonsson Cancer Center found that the children of U.S.-born Latina women are at higher risk of having retinoblastoma, a malignant tumor of the retina which typically occurs in children under six.

Scientists discover biological marker that may help identify patients’ response to antidepressants

Scientists have discovered a biological marker that may help to identify which depressed patients will respond to an experimental, rapid-acting antidepressant. The brain signal, detectable by noninvasive imaging, also holds clues to the agent's underlying mechanism, which are vital for drug development, say National Institutes of Health researchers.

Studies in mice reveal how mood-altering drugs may affect brain stem cells

Working with mice, Johns Hopkins researchers say they have figured out how stem cells found in a part of the brain responsible for learning, memory and mood regulation decide to remain dormant or create new brain cells. Apparently, the stem cells "listen in" on the chemical communication among nearby neurons to get an idea about what is stressing the system and when they need to act.

Changes in monocytes are biomarker for amyotrophic lateral sclerosis

Researchers from Brigham and Women's Hospital (BWH) are the first to discover that changes in monocytes (a type of white blood cell) are a biomarker for amyotrophic lateral sclerosis (ALS), or Lou Gehrig's disease. This finding also brings the medical community a step closer toward a new treatment for the debilitating neurological disease that affects approximately 30,000 Americans.

Fainting appears to have strong genetic predisposition

Fainting has a strong genetic predisposition, according to new research published in the August 7, 2012, print issue of Neurology, the medical journal of the American Academy of Neurology. Fainting, also called vasovagal syncope, is a brief loss of consciousness when your body reacts to certain triggers, such as emotional distress or the sight of blood.

Mutations in Ras gene alone may not cause tumours

Despite a huge amount of research effort, the molecular mechanisms that underlie the transition from a "normal" cell to a cancerous cell are only poorly understood. After the discovery of the first cancer-causing genes or oncogenes and the finding that they are mutated forms of normal cellular genes, it was widely believed that a single mutation was enough to cause cancer.
