Key details of how TRF2 protein performs crucial chromosome-protecting function

We take it for granted that our chromosomes won't stick together, yet this kind of cellular disaster would happen constantly were it not for a protein called TRF2. Now, scientists at The Scripps Research Institute (TSRI) have discovered key details of how TRF2 performs this crucial chromosome-protecting function.

Cells lose ability to defend against transposons as they age

Even in our DNA there is no refuge from rogues that prey on the elderly. Parasitic strands of genetic material called transposable elements - transposons - lurk in our chromosomes, poised to wreak genomic havoc. Cells have evolved ways to defend themselves, but in a new study, Brown University researchers describe how cells lose this ability as they age, possibly resulting in a decline in their function and health.

Scientists receive honorary doctorate for research on Alzheimer's disease

On Monday 4 February, Dennis J. Selkoe and five other "brain teasers" will receive an honorary doctorate from the KU Leuven. The promoters for this honorary doctorate - VIB-KU Leuven professors Bart De Strooper and Wim Robberecht - will honor Dennis J. Selkoe for his scientific insights, but also for his relentless search for new medicines to treat Alzheimer's Disease and other conditions that cause severe damage in the brain.

Identification of progenitors may help treat clinical taste dysfunction

Scientists at the Monell Center have identified the location and certain genetic characteristics of taste stem cells on the tongue. The findings will facilitate techniques to grow and manipulate new functional taste cells for both clinical and research purposes.

Brandeis University researchers to receive Wiley Prize in Biomedical Sciences

Deborah E. Wiley, Chair of The Wiley Foundation, John Wiley & Sons, Inc., announced today that the twelfth annual Wiley Prize in Biomedical Sciences will be awarded to Dr. Michael Young, Rockefeller University, Dr. Jeffrey Hall, Brandeis University (Emeritus), and Dr. Michael Rosbash, Brandeis University.

MDGA proteins associated with autism suppress inhibitory synapse formation

Synapse development is promoted by a variety of cell adhesion molecules that connect neurons and organize synaptic proteins. Many of these adhesion molecules are linked to neurodevelopmental disorders; mutations in neuroligin and neurexin proteins, for example, are associated with autism and schizophrenia.

Phenformin decreases size of lung tumors and increases survival in mice

Ever since discovering a decade ago that a gene altered in lung cancer regulated an enzyme used in therapies against diabetes, Reuben Shaw has wondered if drugs originally designed to treat metabolic diseases could also work against cancer.

Study shows how GATA3 protein acts downstream biochemically to prevent breast cancer metastasis

The spread of breast cancer to distant organs within the body, an event that often leads to death, appears in many cases to involve the loss of a key protein, according to UC San Francisco researchers, whose new discoveries point to possible targets for therapy.

Researchers study innovative stem cell drug for treating localized cartilage damage

Rush University Medical Center is conducting the nation's first clinical study of an innovative stem cell drug, Cartistem, to repair knee cartilage damaged by aging, trauma or degenerative diseases such as osteoarthritis.

Researchers find new genetic differences in human hearts

Healthy men and women show little difference in their hearts, except for small electrocardiographic disparities. But new genetic differences found by Washington University in St. Louis researchers in hearts with disease could ultimately lead to personalized treatment of various heart ailments.

Early-life exposure to TBT chemical can cause obesity

Exposing pregnant mice to low doses of the chemical tributyltin (TBT) - which was used in marine antifouling paints and is used as an antifungal agent in some paints, certain plastics and a variety of consumer products - can lead to obesity for multiple generations without subsequent exposure, a UC Irvine study has found.

Research team describes how the brain controls whisker movements in mice

All parents know the infant milestones: turning over, learning to crawl, standing, and taking that first unassisted step. Achieving each accomplishment presumably requires the formation of new connections among subsets of the billions of nerve cells in the infant's brain. But how, when and where those connections form has been a mystery.

Salk Institute to establish Helmsley Center for Genomic Medicine

The Salk Institute for Biological Studies has received a $42 million gift-the largest in the Institute's history-to establish the Helmsley Center for Genomic Medicine (HCGM), a research center dedicated to decoding the common genetic factors underlying many complex chronic human diseases.

SLU team discovers molecular pathway that contributes to triple-negative breast cancer

In research published in the Jan. 17 issue of The Journal of Cell Biology, a team led by Susana Gonzalo, Ph.D., assistant professor of biochemistry and molecular biology at Saint Louis University, has discovered a molecular pathway that contributes to triple-negative breast cancer, an often deadly and treatment resistant form of cancer that tends to strike younger women.

Brown biology professor named Pew's Scholar of the Month

Biologist Erica Larschan, Ph.D., was named by The Pew Charitable Trusts as the "Scholar of the Month," for her innovative findings on chromosomal activity in fruit flies.

Neuronal reprogramming may help treat neurodegenerative diseases

A new finding by Harvard stem cell biologists turns one of the basics of neurobiology on its head - demonstrating that it is possible to turn one type of already differentiated neuron into another within the brain.

BRCA1-deficient cancer cells take advantage of DNA repair mechanism

Cancer cells are resourceful survivors with plenty of tricks for staying alive. Researchers have uncovered one of these stratagems, showing how cells lacking the tumor suppressor BRCA1 can resume one form of DNA repair, sparing themselves from stagnation or death. The study appears in the January 21st issue of The Journal of Cell Biology.

New details about molecular surveillance system that helps detect and correct errors in cell division

Studies led by cell biologist Thomas Maresca at the University of Massachusetts Amherst are revealing new details about a molecular surveillance system that helps detect and correct errors in cell division that can lead to cell death or human diseases. Findings are reported in the current issue of the Journal of Cell Biology.
