Almac announces study on colorectal pre-malignancies

Almac Diagnostics has announced a major study analysing colorectal polyp tissue samples using its novel Colorectal Cancer DSA microarray.

New device sniffs out olfactory disorders that could be an early warning of Alzheimer's, Parkinson's

The Sniff Magnitude Test (SMT), an invention of UC Psychology Professor Robert Frank and Professor Emeritus Robert Gesteland of the UC Department of Cell Biology, is now under further development with the WR Medical Electronics Company in Stillwater, Minn. The company will manufacture and market the test.

Recognition for cancer researchers

World-class cancer researchers whose science has significantly contributed to progress in the fight against cancer will be recognized April 14-18, 2007, by the American Association for Cancer Research (AACR) at its 2007 Annual Meeting in Los Angeles, Calif.

Regenerative medicine project taps into human stem cells

Researchers at the McKnight Brain Institute of the University of Florida have initiated a project to treat human brain and other diseases by plundering the secrets of regeneration from creatures with remarkable powers of self-renewal, such as salamanders, newts, starfish and flatworms.

DNA repair runs by the biological clock

No sooner have the clocks gone forward than scientists have shed new light on the link between our biological clocks and DNA damage repair processes, essential in protecting our cells from cancer.

Researchers discover vitiligo gene

In a study appearing in the March 22 edition of The New England Journal of Medicine, researchers at St George's, University of London, the University of Colorado at Denver and Health Sciences Center (UCDHSC) and the Barbara Davis Center for Childhood Diabetes have discovered a connection between a gene and the chronic skin condition vitiligo, as well as a possible link to an array of other autoimmune diseases.

Protein duo maintains communication among nerves

Frustration gave way to satisfaction when an experiment that seemed to foil St. Jude researchers actually brought them a step closer to understanding how the brain maintains healthy lines of communications among its nerves.

Chemical cues turn embryonic stem cells into cerebellar neurons

Embryonic stem cells have shown a great deal of promise for alleviating heart disease and regenerating organs. But for some of the conditions for which people hold out the most hope - Alzheimer's and Parkinson's, for example - there's been little evidence to date that stem cells can work.

Cannibalistic signals help mammalian embryos develop normally

A cannibalistic process called autophagy spurs dying embryonic stem cells to send "eat me" and "come get me" signals to have their corpses purged, a last gasp that paves the way for normal mammalian development, UT Southwestern Medical Center researchers have found.

Genetically caused deafness may be reversible by compensating for a missing protein

Emory University researchers have found that in mice, increasing the amount of the protein connexin26 in the ear's cochlea compensates for an absence of another protein, connexin30.

First embryonic stem cell research grants approved under California Proposition 71

The California Institute for Regenerative Medicine's Independent Citizens' Oversight Committee on Friday announced the approval of the first human embryonic stem cell research grants provided under Proposition 71, the San Francisco Chronicle reports.

Translationally controlled tumor protein key to organ growth

When amounts of a small protein called TCTP (translationally controlled tumor protein) are reduced in the cells of fruit flies, they are smaller than normal, indicating that the protein plays a major role in the growth and proliferation of cells, said researchers at Baylor College of Medicine in a report in current issue of the journal Nature.

Newborns with respiratory distress should be evaluated for primary ciliary dyskinesia

Reviewing published reports, Ferkol and Margaret Leigh, M.D., professor of pediatrics at the University of North Carolina at Chapel Hill (UNC), found that neonatal respiratory distress was a common clinical symptom of PCD, a chronic airway disease that affects about 1 in 15,000 children.

Regulator of cholesterol production identified

By first probing the way primitive yeast make cholesterol, a team of scientists has discovered a long-sought protein whose human counterpart controls cholesterol production and potentially drug metabolism.

Epigenetics to shape stem cell future

Everyone hopes that one day stem cell-based regenerative medicine will help repair diseased tissue. Before then, it may be necessary to decipher the epigenetic signals that give stem cells their unique ability to self-renew and transform them into different cell types.

Researchers discover how to fight iron disorders with a drug against hypertension

We all know that iron deficiencies are dangerous, but also too much iron is bad for our health. Our body stores excess iron in various tissues, where it can lead to organ failure and even death if not treated before irreversible damage has occurred.

Changes in breast cancer management

Aggressive research currently underway brings hope of dramatic advances in breast cancer management, according to a new review.

Single transcription factor GABP a major player in cell growth

When cells go about the business of dividing, they can get sidelined. Maybe there aren't enough nutrients. Maybe there aren't the right signals to resume multiplying. Either way, cells go quiet.

Bright quantum dots help basic cancer biology studies

Though there is little doubt that nanoscale devices are going to play a critical role in improving cancer detection and treatment over the next five to ten years, nanoparticles are already having a major impact on the way that cancer biologists study the processes that go awry within malignant and metastatic cells.

Gene produces springy protein keeping nerve cells flexible

If you bend a knee or an elbow, the nerves in your limbs stretch but do not break. A University of Utah study suggests why: A gene produces a springy protein that keeps nerve cells flexible. When the gene was disabled in tiny nematode worms, their nerve cells literally broke.
