MiR-122 plays a critical role in the life cycle of hepatitis C virus

Hepatitis C virus has evolved to invade and hijack the basic machinery of the human liver cell to ensure its survival and spread. Researchers at the University of North have discovered how hepatitis C binds with and repurposes a basic component of cellular metabolism known as a microRNA to help protect and replicate the virus.

Jagaricin and antifungal drugs: an interview with Prof Christian Hertweck

Most people have already experienced a fungal infection (mycosis) of the outer layer of the skin, athlete’s foot or ringworm. Whereas such infections may be cumbersome and often difficult to cure, usually they are not dangerous. However, in cases where a fungus causes a systemic infection, this is, it infects internal organs such as lungs or brain, the infection may turn into a life-threatening disease. Of course, only pathogenic fungi cause problems and the degree of virulence varies.

Lymphocyte clue to multiple sclerosis drug response

Patients with rapid recovery of CD4-positive T cells after alemtuzumab treatment for multiple sclerosis are at risk for disease progression or relapse, research suggests.

Scientists decode VEGF/Ang1/Syx pathway that regulates leakiness of blood vessels

A research team led by scientists at Mayo Clinic in Florida have decoded the entire pathway that regulates leakiness of blood vessels — a condition that promotes a wide number of disorders, such as heart disease, cancer growth and spread, inflammation and respiratory distress.

BubR1 and its associated regulators promising targets for aging disorders and cancer

A new series of studies in mouse models by Mayo Clinic researchers uncovered that the aging process is characterized by high rates of whole-chromosome losses and gains in various organs, including heart, muscle, kidney and eye, and demonstrate that reducing these rates slows age-related tissue deterioration and promotes a healthier life span. The findings appear in today's online issue of Nature Cell Biology.

MiR-181 molecule tied to breast cancer metastasis

Researchers at Case Western Reserve University School of Medicine have identified a molecule linked to more aggressive forms of breast cancer - a discovery that could point the way to potential cures.

Viewpoints: Raising Medicare's entitlement age doesn't save money; New anti-fraud efforts

Looking for ways to slow the growth of entitlement programs, budget negotiators in Washington are considering making seniors wait two years longer to qualify for Medicare - from age 65 to 67. Many Republicans have endorsed the idea, noting that Medicare beneficiaries now live far longer on average than they did when Congress created the program in 1965.

High AngII levels put stress on the ER and cause hypertension

When the heart works too hard, the brain may be to blame, says new Cornell University research that is changing how scientists look at high blood pressure (hypertension). The study, published in the Journal of Clinical Investigation in November, traces hypertension to a newfound cellular source in the brain and shows that treatments targeting this area can reverse the disease.

e-Therapeutics’ ETS2101 cancer trials on track

e-Therapeutics plc today provides an update on the clinical trials of its cancer drug ETS2101. Two phase I studies, one in patients with primary or secondary brain cancer and the other in patients with various solid tumours, remain on track to report final data in Q4 2013 and Q1 2014, respectively. Interim data from the trials are expected in H1 2013.

Advanced MRI can non-invasively evaluate cellular proliferation of tumor models of breast cancer

Scientists at the University of Arizona Cancer Center and the Moffitt Cancer Center, led by Dr. Robert Gillies, have demonstrated that an advanced magnetic resonance imaging (MRI) method can non-invasively evaluate the cellular proliferation of tumor models of breast cancer.

Tbx18 gene directs conversion of cardiomyocytes to genuine pacemaker cells

Cedars-Sinai Heart Institute researchers have reprogrammed ordinary heart cells to become exact replicas of highly specialized pacemaker cells by injecting a single gene (Tbx18)-a major step forward in the decade-long search for a biological therapy to correct erratic and failing heartbeats.

Germ cell removal may promote longevity

The gonad is well known to be important for reproduction but also affects animal life span. Removal of germ cells - the sperm and egg producing cells - increases longevity of the roundworm Caenorhabditis elegans. However, the underlying molecular mechanisms were a mystery. Now scientists at the Cologne-based Max Planck Institute for Biology of Ageing, have discovered that germ cell removal flips a "molecular switch" that extends the life span by using components of a "developmental clock".

Study investigates muscle weakness in mouse model of Down syndrome

It is well known that people with Down syndrome (DS) suffer from marked muscle weakness. Even the simple tasks of independent living, such as getting out of a chair or climbing a flight of stairs, can become major obstacles. This can reduce the quality of life for those with DS and lead to a loss of independence. Now, a new study sheds light on some of the suspected causes of muscle weakness.

New MIT technology may help make cancer biomarker detection much easier

Finding ways to diagnose cancer earlier could greatly improve the chances of survival for many patients. One way to do this is to look for specific proteins secreted by cancer cells, which circulate in the bloodstream. However, the quantity of these biomarkers is so low that detecting them has proven difficult.

University of North Carolina awards 13th Perl prize to two NTNU-Trondheim scientists

The University of North Carolina at Chapel Hill has awarded the 13th Perl-UNC Neuroscience prize jointly to Edvard and May-Britt Moser at the Norwegian University of Science and Technology (NTNU-Trondheim) in Trondheim, Norway.

Researchers identify possible heredity mechanism that predisposes children to ALL

Researchers at the Sainte-Justine University Hospital Center and the University of Montreal have found a possible heredity mechanism that predisposes children to acute lymphoblastic leukemia (ALL), the most common type of blood cancer in children. According to their findings published in Genome Research, the presence of a genetic defect in the egg or sperm from which children having ALL arise may be a prerequisite for the disease to develop.
