Molecule provides clues about how HPV may lead to cancer

New research shows for the first time that certain types of human papillomavirus (HPV), which cause cervical and some other types of cancer, can inhibit the production of a tiny single-stranded RNA called microRNA 34a, or miR-34a.

Discovery of gene that modifies severity of cystic fibrosis lung disease

Researchers at Wake Forest University Baptist Medical Center, and colleagues, have identified a gene that modifies the severity of lung disease in people with cystic fibrosis, a lethal genetic condition. The findings open the door to possible new targets for treatment, researchers say.

New protein identified in bacterial arsenal

Nearly a billion years ago, bacteria evolved an insidious means of infecting their hosts - a syringe-like mechanism able to inject cells with stealthy hijacker molecules. These molecules, called virulence factors, play a sophisticated game of mimicry, imitating many of the cells' normal activities but ultimately co-opting them to serve the bacteria's needs.

Link between, bacteria, cancer explored with funding from American Cancer Society

The role of bacteria in the development of colorectal cancer is coming under scrutiny at the University of Rochester Medical Center, thanks to an $840,000 research award from the American Cancer Society.

Angiogenesis inhibitors, study points to limitations, solutions

A new generation of cancer drugs designed to starve tumors of their blood supply - called "angiogenesis inhibitors"-succeeds at first, but then promotes more invasive cancer growth-sometimes with a higher incidence of metastases, according to a new study in animals.

A new monkey model for HIV

By altering just one gene in HIV-1, scientists have succeeded in infecting pig-tailed macaque monkeys with a human version of the virus that has until now been impossible to study directly in animals.

New treatment target for chronic abdominal pain

High levels of a protein linked to the way pain signals are sent to the brain led to a decrease in abdominal pain in a recent study in mice.

Protein complex shown to play pivotal role in stem cell development

Scientists at the Stanford University School of Medicine have identified a protein complex important in controlling whether embryonic stem cells retain their ability to become any cell in the body - a quality called pluripotency - or instead embark on a pathway of maturation and specialization.

Newly discovered protein points to new treatment for serious lung disease

The discovery by Uppsala University researchers of a previously unknown protein in the cells of the lower air ways brings new potential for early diagnosis of a serious lung disease.

New clues about mitochondrial 'growth spurts'

Mitochondria are restless, continually merging and splitting. But contrary to conventional wisdom, the size of these organelles depends on more than fusion and fission, as Berman et al. show. Mitochondrial growth and degradation are also part of the equation.

New mechanistic explanation of how the brain interprets stress signals

Chronic stress takes a physical and emotional toll on our bodies and scientists are working on piecing together a medical puzzle to understand how we respond to stress at the cellular level in the brain.
