Making of mouse marks move toward 'mitochondrial medicine'

... we did have, we have a lot of work ahead of us to figure out why the numbers are so low," says Pinkert, professor of pathology and laboratory medicine, who was attracted to the university three years ago by a thriving community of researchers focusing on genetic engineering and mitochondrial biology. "It's...

Araucariaceae of New-Caledonia: endemic species in danger

...rs, all of them endemic. On the global scale, that figure represents 45% of all species of this family. They are divided between two genera, Agathis (or kaoris) and Araucaria (columnar pines), consisting respectively of 5 and 13 species. Several of them are important economically, as a source of timber, and...

Parasite's enzyme structure helps address a public health issue

...s important to learn the structure of a protein to figure out how it works." Researchers in Anderson's lab also work on the same enzyme model for Toxoplasma, cousin to Cryptosporidium. The advantage, Anderson explains, is that by solving this enzyme's structure for both Cryptosporidium and Toxoplasma, the...

About 63 percent o...

Brain tumor growth requires abnormal neighbors

... both copies of the Nf1 gene," he explains. "If we figure out what external cues are necessary to trigger tumor growth, we could try to shut off that switch and stop tumors dead in their tracks without having to correct the underlying genetic defect." The potential for the mouse model used in this study to ...

Yeast helps researchers better understand Parkinson's mystery

... the disease's debilitating symptoms. The quest to figure out how these clusters form and how to prevent them has been slow and difficult. Now, after years of painstaking research, scientists have succeeded in duplicating the disease's most critical features in the most readily manipulated model organism...

The data used for the analysis in Brazil came from that country's first-ever national household survey intended to a...

Global wetlands surveyed from space

...cosystems published in Nature in 1997 arrived at a figure of 27.7 trillion Euros (33 trillion dollars), with wetland ecosystems making up 12.5 trillion ($14.9 trillion) or 45% - of this total. Much of human civilisation has been based around river valleys and floodplains. However, global freshwater consum...

Researchers find role RNA plays in progress of Alzheimer's disease

Age-related decrease in physical ability may be in the genes

...ases as we age, but no one has really been able to figure out what the basis of these changes may be. Rotter and his colleagues are going further with their studies of gene expression in mice. They are currently looking at the effects that low-calorie diets have on gene expression in the mouse cerebellum. R...

Breast cancer can be reversed in laboratory mice, scientists report

"Proteomics is important to researchers in many specialties, but especially in biomedical research," Andrews says. "Proteins can be used as biomarkers to detect the earliest stages of diseases like cancer or d...

JAK2 enzyme helps protect brain cells, wreaks havoc on blood vessels

... tamoxifen works in those cells. "We are trying to figure out how various compounds might be able to regulate JAK," says Dr. Marrero. "We know nicotine activates it, which is why we are studying it." He wants to find additional compounds that activate or inhibit JAK2 so he can maximize the protective qualit...
