Proteins are complex molecules that are made up of amino acids. They can be found in every cell in the body, and carry out vital processes that keep human beings alive. Mutations in proteins can lead to a multitude of diseases, the most common being cancer.

How an opportunistic fungal pathogen knows when to attack

The opportunistic fungal pathogen Candida albicans inconspicuously lives in our bodies until it senses that we are weak, when it quickly adapts to go on the offensive. The fungus, known for causing yeast and other minor infections, also causes a sometimes-fatal infection known as candidemia in immunocompromised patients. An in vivo study, published in mBio, demonstrates how C. albicans can distinguish between a healthy and an unhealthy host and alter its physiology to attack.

New cell regeneration method uses gene therapy to repair bone tissue

Researchers at the Royal College of Surgeons in Ireland (RCSI) have developed a new method of repairing bone using synthetic bone graft substitute material, which combined with gene therapy, can mimic real bone tissue and has potential to regenerate bone in patients who have lost large areas of bone from either disease or trauma.

MASL protein from plant's seeds may halt spread of melanoma

An international team of scientists led by Gary Goldberg, PhD, of the University of Medicine and Dentistry of New Jersey-School of Osteopathic Medicine (UMDNJ-SOM), has found that a protein from the seeds of a plant used for centuries in traditional medicines may be able to halt the spread of melanoma, a lethal form of skin cancer.

HemoGlobe device can identify women with anemia

Could a low-cost screening device connected to a cell phone save thousands of women and children from anemia-related deaths and disabilities? That's the goal of Johns Hopkins biomedical engineering undergraduates who've developed a noninvasive way to identify women with this dangerous blood disorder in developing nations. The device, HemoGlobe, is designed to convert the existing cell phones of health workers into a "prick-free" system for detecting and reporting anemia at the community level.

New tool uses fluorescence to distinguish cancerous tissue from normal one in low-grade tumors

A new probe developed collaboratively at Norris Cotton Cancer Center and Dartmouth College's Thayer School of Engineering uses an innovative fluorescence-reading technology to help brain surgeons distinguish cancerous tissue from normal tissue. The probe tool, now already in use at the Cancer Center for brain surgery, may one day be used for surgeries for a variety of cancers.

New algorithm can help scientists predict gene and drug interactions

Researchers from Mount Sinai School of Medicine have developed a new computational method that will make it easier for scientists to identify and prioritize genes, drug targets, and strategies for repositioning drugs that are already on the market. By mining large datasets more simply and efficiently, researchers will be able to better understand gene-gene, protein-protein, and drug/side-effect interactions. The new algorithm will also help scientists identify fellow researchers with whom they can collaborate.

Study identifies MDM4 protein as promising target for treatment of melanoma

A melanoma is a malignant form of skin cancer and is one of the most aggressive types of tumors there is. Treatment is particularly difficult, because melanomas are usually resistant against conventional chemotherapy treatments.
