Exposing how pancreatic cancer does its dirty work

Pancreatic cancer is one of the most insidious forms of the disease, in which an average of only 9% of patients are alive five years after diagnosis. One of the reasons for such a dismal outcome is that pancreatic cancer ...

Damaged lungs regenerated in study

A new technique to rehabilitate lungs that are too damaged to be considered for transplant could benefit an increasing population of patients with end-stage lung disease.

Engineered stem cells seek out, kill HIV in living organisms

(Medical Xpress) -- Expanding on previous research providing proof-of-principal that human stem cells can be genetically engineered into HIV-fighting cells, a team of UCLA researchers have now demonstrated that these cells ...

Researchers examine mechanisms that help cancer cells proliferate

A process that limits the number of times a cell divides works much differently than had been thought, opening the door to potential new anticancer therapies, researchers at UT Southwestern Medical Center report in the Aug. ...

Zebrafish aid effort to regenerate damaged retinas

The tiny zebrafish may hold the secret to regenerating damaged retinas in humans, Vanderbilt University researchers reported last week in the journal Cell Reports.

Study highlights danger of vitamin B12 deficiency

Using roundworms, one of Earth's simplest animals, Rice University bioscientists have found the first direct link between a diet with too little vitamin B12 and an increased risk of infection by two potentially deadly pathogens.

Model organism

A model organism is a species that is extensively studied to understand particular biological phenomena, with the expectation that discoveries made in the organism model will provide insight into the workings of other organisms. In particular, model organisms are widely used to explore potential causes and treatments for human disease when human experimentation would be unfeasible or unethical. This strategy is made possible by the common descent of all living organisms, and the conservation of metabolic and developmental pathways and genetic material over the course of evolution. Studying model organisms can be informative, but care must be taken when generalizing from one organism to another.
