Study reveals why development of HIV treatments has been difficult

A new research report appearing in the March 2012 issue of the journal Genetics shows why the development of a cure and new treatments for HIV has been so difficult. In the report, an Australian scientist explains how he used computer simulations to discover that a population starting from a single human immunodeficiency virus can evolve fast enough to escape immune defenses.

PCP signaling restricts neural growth during regeneration, homeostasis and development

The genetic pathway that regulates the way cells align themselves relative to each other has been found to act as a "stop sign" that signals organisms when to halt cell growth, according to new research published by biologists at the Center for Regenerative and Developmental Biology in Tufts University's School of Arts and Sciences.

CCN1 protein orchestrates cellular antiviral response in the extracellular matrix

Brain-tumor cells that are infected with a cancer-killing virus release a protein "alarm bell" that warns other tumor cells of the impending infection and enables them to mount a defense against the virus, according to a study led by researchers at The Ohio State University Comprehensive Cancer Center - Arthur G. James Cancer Hospital and Richard J. Solove Research Institute.

Combination therapy may improve life span and motor function of infants with Batten disease

Infants with Batten disease, a rare but fatal neurological disorder, appear healthy at birth. But within a few short years, the illness takes a heavy toll, leaving children blind, speechless and paralyzed. Most die by age 5.

New technique can sensitize cancer cells to radiation

Researchers at Winship Cancer Institute are developing a technique to remove cancer cells' defenses against radiation.

Roundtable teleconference on nanotechnology against cancer

Imagine a test that sifts through millions of molecules in a drop of a patient's blood to detect a telltale protein signature of a cancer subtype, or a drug ferry that doesn't release its toxic contents until it slips inside cancer cells.

Many people do not recognize stroke symptoms

Nationwide ambulance use by patients suffering from a stroke has not changed since the mid-1990s, even though effective stroke treatments are now available.

Study identifies 190 proteins crucial to the functions of key immune sensors

In a healthy immune system, invading pathogens trigger a cascade of alerts and responses to fight off the infection. Sensors called toll-like receptors, or TLRs, act as one of the first lines of defense. Two of these sensors, known as TLR7 and TLR9, specifically recognize and respond to microbial RNA and DNA, respectively. But what determines how these TLRs get where they need to be and sound the alarm for pathogen infection?

H. pylori bacteria associated with elevated levels of HbA1c

A new study by researchers at NYU Langone Medical Center reveals that the presence of Helicobacter pylori (H. pylori) bacteria is associated with elevated levels of glycosylated hemoglobin (HbA1c), an important biomarker for blood glucose levels and diabetes.

Anti-inflammatory drugs may offer novel treatment for CHD

A large international study indicates that anti-inflammatory drugs may become a new tool for preventing and treating coronary heart disease (CHD), the leading global cause of death.

MDxHealth fourth quarter total revenues increase 48% to €0.9M

MDxHealth SA, a leading molecular diagnostic company that develops and commercializes epigenetic tests to support cancer treatment, today announced results for Q4 and full year 2011.

MAPKAP kinase 2 plays an important role in progression of GIST

Gastrointestinal stroma tumours (GIST) are a very particular challenge for cancer research. For once the tumours, which are mostly located in the stomach, are relatively rare (approx. 100 new cases/year in Austria) and hence are difficult to research. On the other side its behaviour varies quite a lot. While some GIST tumours are relatively harmless, others may become metastatic.

Doctors can use genetic profiling to more accurately predict patients with AML

Researchers have identified a set of genetic abnormalities in patients with acute myelogenous leukemia (AML) that doctors can use to more accurately predict patients' prognoses and select treatments that are most likely to benefit them.

Study provides insight into developing new treatment strategies for triple-negative breast cancer

A new study by University of Kentucky researchers provides insight into developing new treatment strategies for basal-like breast cancer, commonly known as triple-negative breast cancer. This cancer is associated with early metastasis and resistance to chemotherapy and occurs at women at a younger age.

Researchers identify epigenetic signatures within reprogrammed skin cells

A research team has identified epigenetic signatures, markers on DNA that control transient changes in gene expression, within reprogrammed skin cells.

New experimental technique can produce cells with specific functions

Researchers at the RIKEN Omics Science Center (OSC) have successfully developed and demonstrated a new experimental technique for producing cells with specific functions through the artificial reconstruction of transcriptional regulatory networks. As an alternative to induced pluripotent stem cells, the technique promises to enable faster and more efficient production of functional cells for use in cancer therapy and a variety of other areas.

Scientists identify new compound that quickly kills HCC cells

Scientists have identified a new compound that rapidly kills hepatocellular carcinoma (HCC) cells, the most common form of liver cancer and fifth most common cancer worldwide, while sparing healthy tissue.

Mutated ATRX gene associated with advanced-stage neuroblastoma

Certain mutations of the gene ATRX were associated with age at diagnosis in children and young adults with advanced-stage neuroblastoma, a cancer that grows in parts of the nervous system, according to a study in the March 14 issue of JAMA.
