Clues to skeletal form in ‘feelgood’ fish

Dec. 16, 2011—Ela Knapik, associate professor of medicine, and colleagues are using zebrafish to explore the molecular and cellular mechanisms that cause birth defects of the face and skeleton.

Divvying up chromosomes

Dec. 16, 2011—Mitosis, or the separation of chromosomes during cell division, is driven by dynamic interactions between the kinetochore region on chromosomes and string-like structures called microtubules. A number of proteins, including the enzyme Cdk1, regulate these interactions, but it is unclear what kinetochore components such enzymes work upon. Kathy Gould, professor of cell and developmental biology,...

Young stem cells counter kidney aging

Dec. 15, 2011—Young bone marrow cells alleviate aging-related kidney changes in mice.

Divvying up chromosomes

Dec. 15, 2011—Protein helps ensure proper division of chromosomes during cell division.

Virus-linked cancer gets help from host

Dec. 15, 2011—Host cell protein may be a target for strategies to limit spread of virus-induced squamous cell cancers.

Move out, cholesterol

Dec. 8, 2011—Compounds developed at Vanderbilt could offer a whole new way to treat atherosclerosis.

Lung nodule surgery not always “futile”

Dec. 7, 2011—Even when lung operations for suspected cancer resection results in a benign diagnosis, there still may be significant benefits to the procedure, new research suggests.

Pathway to colon cancer progression

Dec. 1, 2011—Molecular players involved in colon cancer progression could provide new biomarkers to indicate invasiveness and prognosis.

Exercise fights fatty liver

Nov. 18, 2011—Fatty liver, a reversible condition of fat accumulation in liver cells, can result from excessive alcohol consumption, obesity, type 2 diabetes, or metabolic disorders. Exercise can reverse this process, but the mechanisms underlying this effect are not clear. Because exercise is known to stimulate the action of glucagon (a hormone that raises blood glucose levels)...
