Folate, excision biomarkers not predictive for small-cell lung cancer response

Biomarkers associated with the folate metabolism and excision repair pathways are not sufficiently prognostic to aid chemotherapy decisions for patients with extensive-stage disease small-cell lung cancer, results of a phase III trial show.

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.

TXNIP protein provides best available target for therapies against diabetes, Wolfram syndrome

Inflammation and cell stress play important roles in the death of insulin-secreting cells and are major factors in diabetes. Cell stress also plays a role in Wolfram syndrome, a rare, genetic disorder that afflicts children with many symptoms, including juvenile-onset diabetes.

BioDiem granted European patent for antimicrobial drug

Australian vaccine development company BioDiem Ltd (ASX: BDM) announced today the successful granting of a key European patent for its synthetic antimicrobial compound BDM-I. BDM-I is a novel compound active against a range of pathogenic micro-organisms including bacteria, fungi and protozoa. The patent provides protection around BDM-I as a treatment for vulvovaginitis, a general term for inflammation of the vulva or vagina.

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.

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.

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.

Potential drug targets and prognostic markers for prostate cancer

Two proteins that act in opposing directions - one that promotes cancer and one that suppresses cancer - regulate the same set of genes in prostate cancer, Vanderbilt-Ingram Cancer Center researchers have found.

NeoGenomics introduces new molecular assay that detects SF3B1 gene mutations

NeoGenomics, Inc., a leading provider of cancer-focused genetic testing services, announced today that it has validated and launched the first molecular assay for clinical use in the United States that detects mutations in the SF3B1 gene (splicing factor 3b, subunit 1).

Clovis Oncology, Foundation Medicine enter diagnostic collaboration

Foundation Medicine, Inc. and Clovis Oncology, Inc. announced today that they have entered into a diagnostic collaboration.

Scientists identify key factor that drives resistance to cancer drug

Developing resistance to chemotherapy is a nearly universal, ultimately lethal consequence for cancer patients with solid tumors - such as those of the breast, prostate, lung and colon - that have metastasized, or spread, throughout the body. A team of scientists led by Fred Hutchinson Cancer Research Center has discovered a key factor that drives this drug resistance - information that ultimately may be used to improve the effectiveness of therapy and buy precious time for patients with advanced cancer.

New sequencing approach can provide more effective method of BRCA1/2 mutational analysis

Individuals with mutations in BRCA1 and BRCA2 genes have a significantly higher risk of developing breast and ovarian cancers. Families at risk have been seeking genetic testing and counseling based on their mutation carrier status, but the standard method of direct sequencing is labor-intensive, costly, and it only targets a part of the BRCA1 and BRCA2 genes.

Human HLA genes are evolving much more rapidly than previously thought

Human HLA genes - the genes that allow our immune system to tell the difference between our own cells and foreign invaders - are evolving much more rapidly than previously thought, according to an article online on August 3rd in Trends in Genetics. The resulting degree of variation improves our ability to fight off disease, but could also present challenges to current worldwide efforts aimed at identifying potential donors for patients undergoing stem cell transplantation.

Planarian flatworms now a model system for studying eye development and eye diseases

Planarian flatworms have come under intense study for their renowned ability to regenerate any missing body part, even as adults. But now they may take on a starring role as a model system for studying eye development and eye diseases in vertebrates, including humans.

HSF1 increases expression of chaperones and supports cancer metastasis

Whitehead Institute researchers have found that increased expression of a specific set of genes is strongly associated with metastasis and death in patients with breast, colon, and lung cancers.

Researchers discover surprising and unexpected plasticity in the embryonic endothelium

UCLA stem cell researchers have found for the first time a surprising and unexpected plasticity in the embryonic endothelium, the place where blood stem cells are made in early development.

Researchers uncover 9 new genes associated with bone health

Researchers have uncovered 9 new genes associated with bone health. This collaborative study found clues to the cause of bone disorders such as osteoporosis, osteogenesis imperfecta, and high bone density syndromes by investigating the bone mineral content, strength and flexibility.
