Scientists discover how motors maneuver cells' intricate roadway system

Scientists discover how motors maneuver cells' intricate roadway system

Much like motors power our cars, they also ensure that proteins get to the right place in our cells, and a wide variety of diseases - from cancer to heart problems - can result when they don't. [More]
Applying quantitative microscopy to live cells

Applying quantitative microscopy to live cells

Microscopy's got a long history. It was developed about 350 years ago for scientists to visualize things they could discern, but not describe. The two pioneers of microscopy were Antoine van Leeuwenhoek, who developed the first microscope and soon after the renowned scientist, Robert Hooke. [More]

New oncogene may contribute to high incidence of prostate cancer among African American men

New oncogene may contribute to high incidence of prostate cancer among African American men

A team of scientists has identified MNX1 as a new oncogene - a gene than can cause cancer - that is more active in African American prostate cancer than in European American prostate cancer. [More]
Scientists suggest potential approach of lowering tau levels to thwart Alzheimer's disease

Scientists suggest potential approach of lowering tau levels to thwart Alzheimer's disease

Taking a pill that prevents the accumulation of toxic molecules in the brain might someday help prevent or delay Alzheimer's disease, according to scientists at Baylor College of Medicine, Texas Children's Hospital and Johns Hopkins University School of Medicine. [More]
Researchers to explore potential roles of tumor-suppressor gene in kidney cancer

Researchers to explore potential roles of tumor-suppressor gene in kidney cancer

Renal cell carcinoma is the most common type of kidney cancer, and African-Americans and males appear most at risk for this disease that can be asymptomatic until it has spread and become highly lethal, said Dr. Vinata B. Lokeshwar, cancer researcher and chair of the Department of Biochemistry and Molecular Biology at the Medical College of Georgia at Augusta University. [More]
Researchers suggest need for human studies to examine effects of cannabinoid use during pregnancy

Researchers suggest need for human studies to examine effects of cannabinoid use during pregnancy

In this new era of legalized marijuana, far too little research has been conducted on the effect of cannabis on the development of human embryos, say researchers at Georgetown University Medical Center who scoured medical literature on the topic and found what they say is worrisome animal research.

Experts receive $5.2 million NIH grant to develop affordable test for diagnosing Chagas disease

Experts receive $5.2 million NIH grant to develop affordable test for diagnosing Chagas disease

An international team of researchers led by infectious disease experts at the University of Georgia has received $5.2 million from the National Institutes of Health to develop a more accurate, affordable diagnostic test for Chagas disease, a parasitic infection that kills more than 50,000 people each year in Central and South America.

Gene therapy may be viable approach for treating CF lung problems

Gene therapy may be viable approach for treating CF lung problems

Two new studies from the University of Iowa suggest that gene therapy may be a viable approach for treating or preventing lung disease caused by cystic fibrosis. [More]
Researchers identify mutant traits in mouse for many human disease genes

Researchers identify mutant traits in mouse for many human disease genes

About one-third of all genes in the mammalian genome are essential for life. An international, multi-institutional research collaboration identified, for the first time, mutant traits in the mouse for 52 human disease genes, which significantly contributes to the understanding of the genetic bases for some human diseases, including cardiovascular defects, spina bifida, and metabolic disorders, among many others. The study was published this week in Nature. [More]
Mitosis study identifies new potential target for cancer therapy

Mitosis study identifies new potential target for cancer therapy

Structural biologists show in a new study that an apparently key step in the process of cell division depends on a unique interaction among specific proteins, including one that is strongly linked to cancer. Their hope now is that the detailed new characterization of the interaction will make it a target for exploring a new cancer therapy. [More]
Researchers working to find faster way to treat sleeping sickness using oral drugs

Researchers working to find faster way to treat sleeping sickness using oral drugs

Researchers at the University of Georgia are working to find the fastest way possible to treat and cure human African trypanosomiasis, long referred to as sleeping sickness. By working to improve chemical entities already tested in human clinical trials, they hope to have a faster route to field studies to treat the disease using drugs that can be administered orally to patients.

UC Davis scientists show how cells control DNA synthesis in mitochondria

UC Davis scientists show how cells control DNA synthesis in mitochondria

Aging, neurodegenerative disorders and metabolic disease are all linked to mitochondria, structures within our cells that generate chemical energy and maintain their own DNA. In a fundamental discovery with far-reaching implications, scientists at the University of California, Davis, now show how cells control DNA synthesis in mitochondria and couple it to mitochondrial division.

International project to develop globally accessible bank of new cancer cell models for research

An international project to develop a large, globally accessible bank of new cancer cell culture models for the research community launched today. [More]
Pain reliever appears to help preserve vision in animal model of retinal degeneration

Pain reliever appears to help preserve vision in animal model of retinal degeneration

A pain medicine that potently activates a receptor vital to a healthy retina appears to help preserve vision in a model of severe retinal degeneration, scientists report. [More]
Researchers aim to protect kidneys while improving cisplatin's efficacy against cancer

Researchers aim to protect kidneys while improving cisplatin's efficacy against cancer

Cisplatin is a common, powerful chemotherapy agent used for a wide range of cancers such as breast, ovarian and lung, that in a handful of days can also permanently damage or destroy patients' kidneys. [More]
New FDA draft guidelines place tighter restrictions on surgical practices using tissue-based regenerative therapies

New FDA draft guidelines place tighter restrictions on surgical practices using tissue-based regenerative therapies

The therapeutic use of human cell and tissue products is highly regulated by the U.S. government, but a specific exception allows surgeons to harvest, manipulate, and implant tissues in many commonly performed procedures. [More]
UCLA scientists discover cystatin E/M protein that can inhibit cervical cancer growth

UCLA scientists discover cystatin E/M protein that can inhibit cervical cancer growth

UCLA scientists have identified a protein that has the potential to prevent the growth of cervical cancer cells. The discovery could lead to the development of new treatments for the deadly disease. [More]
OIST scientists reveal how big protein complex inside E. coli cells divide and multiply

OIST scientists reveal how big protein complex inside E. coli cells divide and multiply

Escherichia coli (E. coli) are bacteria that live all around and inside of us. Most E. coli are harmless, but some strains can cause illness, and can even, in extreme cases, be deadly. With recent outbreaks of E. coli around the world, there is a fear of acquiring an infection from these bacteria. [More]
