Cells in immune system react to stomach ulcer bacterium Helicobacter pylori, identify researchers

Researchers have identified cells in the immune system that react to the stomach ulcer bacterium Helicobacter pylori, one of the risk factors for the development of stomach cancer. This discovery could lead to faster diagnosis and treatment as well as a better prognosis for patients with stomach cancer, reveals a thesis from the University of Gothenburg, Sweden.

Engineered allosteric regulation provides precise control of kinase activity in living cells

Cancer occurs when human cells move and multiply inappropriately. Within cells, a process called phosphorylation serves as an on/off switch for a number of cellular processes that can be involved in cancer, including metabolism, transcription, configuration, movement, cell death and differentiation. This process is controlled by a group of enzymes called protein kinases that - working together and separately - modify the structure of proteins, changing them and allowing them to control cellular processes.

Transposons create genomic instability and are implicated in cancer and other diseases: Research

Transposons, or "jumping genes," make up roughly half of the human genome. Geneticists previously estimated that they replicate and insert themselves into new locations roughly one in every 20 live births.

Helicos BioSciences to develop, market MDx tests that utilize HeliScope Single Molecule Sequencer

Helicos BioSciences Corporation announced today that it is in the early stages of validating molecular diagnostic (MDx) tests that utilize its HeliScope® Single Molecule Sequencer. The HeliScope Sequencer's ability to sequence single molecules of natural, unamplified DNA or RNA simplifies the diagnostic testing workflow obviating the need for the amplification steps utilized by most genetic analysis methods.

Scientists uncover variations in X chromosome inactivation in early passages of female embryonic stem cells

Human embryonic stem cells hold great promise for studying and treating disease and for the practice of regenerative medicine. However, more must be learned to ensure the cells that may one day be transplanted into humans are safe.

Antioxidant therapy may prevent long-lasting cognitive impairment in cerebral malaria: Research

Using an experimental mouse model for malaria, an international group of scientists has discovered that adding antioxidant therapy to traditional antimalarial treatment may prevent long-lasting cognitive impairment in cerebral malaria. Their findings were published online June 24, 2010, in the journal PLoS Pathogens.

Researchers identify novel protein complex that regulates genes in fruit flies and mammals

Researchers from the European Molecular Biology Laboratory in Heidelberg, Germany, and the Max-Planck Institute of Immunobiology Freiburg have identified a novel protein complex that regulates around 4000 genes in the fruit fly Drosophila and likely plays an important role in mammals, too. Published today in Molecular Cell, their findings explain how another regulatory protein can lead a double life.

Mechanism that regulates stem-cell differentiation in mice may trigger degenerative disease in humans: Research

A mechanism that regulates stem-cell differentiation in mice testes suggests a similar process that may trigger degenerative disease in humans, according to a Penn State College of Agricultural Sciences reproductive physiologist.

Genomic analysis leads to more effective diagnostic tests, treatment options for prostate cancer: Study

A unique collaboration among physician-scientists at Memorial Sloan-Kettering Cancer Center has yielded the most comprehensive genomic analysis of prostate cancer to date. "Genomic studies in other cancer types have resulted in new drug targets and strategies to classify patients into clinically meaningful subgroups that improve treatment decisions," said senior study author Charles Sawyers, Chair of the Human Oncology and Pathogenesis Program at MSKCC and a HHMI investigator. "This first -ever database of its type brings us one step closer to achieving that goal in prostate cancer."

TLR4 may provide new strategy for treating patients with PDAC: Study

Pancreatic ductal adenocarcinoma is a highly malignant digestive tumor with a very poor prognosis. Hypoxia-inducible transcription factor-1α is involved in malignant progression in many solid tumors, including PDAC, upregulation of HIF-1α accelerates PDAC progression, but the exact regulatory mechanisms of HIF-1αin PDAC has not been unequivocally addressed.

ARS study finds link between vitamin D and cognitive function

At a time when consumer interest in health-enhancing foods is high, Agricultural Research Service (ARS)-funded scientists have contributed to a limited but growing body of evidence of a link between vitamin D and cognitive function.

Researchers identify a key player in dramatic loss of neurons in mice and fly models

A team of researchers, led by scientists at the University of California, San Diego, have identified a key player in the dramatic loss of neurons in mice and fly models, a discovery that could help illuminate the role of mitochondrial dysfunction in human neurodegenerative disorders, such as Parkinson's disease.

Scientists discover characteristic amyloid plaques in retinas from Alzheimer's disease patients

The nerve cell-damaging plaque that builds up in the brain with Alzheimer's disease also builds up in the retinas of the eyes - and it shows up there earlier, leading to the prospect that noninvasive optical imaging of the eyes could lead to earlier diagnosis, intervention and monitoring of the disease, according to new research.

Research findings suggest possible diagnostic test for ALS

A team led by a Los Angeles Biomedical Research Institute researcher developed a novel approach to efficiently identify disease relevant genes in human complex neurological disorders and demonstrated the effectiveness of this method by applying it to Amyotrophic Lateral Sclerosis, or Lou Gehrig's Disease, according to a new study reported online in the journal, Human Molecular Genetics.

Researchers uncover association between free radical-mediated reactions and progression of SLE

University of Texas Medical Branch researchers have uncovered an association between free radical-mediated reactions and the severity and progression of system lupus erythematosus. Higher levels of oxidative and nitrosative stress markers were found in SLE patients with greater disease activity suggesting a causal relationship. Full findings of the study are available in the July issue of Arthritis & Rheumatism, a journal published by Wiley-Blackwell on behalf of the American College of Rheumatology.

PARP inhibitors may be effective in men with prostate cancer due to BRCA2 alteration: Researchers

The way prostate cancer develops in men who have an altered 'breast cancer gene' is the same route by which breast cancer develops in women with the same mutation, reveals a study published in PLoS Genetics today (Thursday).
