Molecular ‘timetable’ could aid personalized medicine

Researchers have developed a method, based on analysis of circadian rhythm metabolites in blood samples, which can pinpoint the time of the body’s internal “clock” to within 3 hours.

Converting blood cells to a stem cell state: an interview with Elias Zambidis, M.D., Ph.D.

The primitive stem cell state we created is called an “induced pluripotent stem cell” (iPSC). iPSC are a new, unique, and artificially-created type of stem cell that were first described in 2006 by a Japanese scientist named Shinya Yamanaka.

PD0325901 drug may hold potential to prevent neurofibromatosis 1 in children

A drug originally developed to stop cancerous tumors may hold the potential to prevent abnormal brain cell growth and learning disabilities in some children, if they can be diagnosed early enough, a new animal study suggests.

Metabolism drives the brain clock, reveals study

The rhythm of life is driven by the cycles of day and night, and most organisms carry in their cells a common, (roughly) 24-hour beat. In animals, this rhythm emerges from a tiny brain structure called the suprachiasmatic nucleus (SCN) in the hypothalamus. Take it out of the brain and keep it alive in a lab dish and this "brain clock" will keep on ticking, ramping up or gearing down production of certain proteins at specific times of the day, day after day.

Alcohol can cause more than one pattern of birth defects

A collaborative research effort by scientists at the University of North Carolina School of Medicine, Duke University, and University College of London in the UK, sheds new light on alcohol-related birth defects.

Thiabendazole drug slows tumor growth and shows promise as chemotherapy for cancer

An inexpensive antifungal drug, thiabendazole, slows tumor growth and shows promise as a chemotherapy for cancer. Scientists in the College of Natural Sciences at The University of Texas at Austin made this discovery by exploiting the evolutionary relatedness of yeast, frogs, mice and humans.

Potential new drug to treat common inherited kidney disease

Scientists at UC Santa Barbara have demonstrated in the laboratory that a new drug is effective in treating a very common kidney disease -- although it will be a few years before it becomes available for clinical testing. The findings resulted from a collaboration between UCSB and a biotech firm based in Indiana. The study is published in this week's Journal of the American Society of Nephrology.

Researchers discover surprising and unexpected plasticity in the embryonic endothelium

UCLA stem cell researchers have found for the first time a surprising and unexpected plasticity in the embryonic endothelium, the place where blood stem cells are made in early development.

New insight into why glioblastoma multiforme recurs in adults

A study by UT Southwestern Medical Center researchers published online today in Nature reveals new insight into why the most common, deadly kind of brain tumor in adults recurs and identifies a potential target for future therapies.

EPHA3 mutations may be important drivers of lung cancers

Vanderbilt-Ingram Cancer Center researchers have identified how one of the genes most commonly mutated in lung cancer may promote such tumors.

Fruit flies help pinpoint genetic changes that spell cancer

By studying fruit flies, scientists at A*STAR's Institute of Molecular and Cell Biology (IMCB) have successfully devised a fast and cost-saving way to uncover genetic changes that have a higher potential to cause cancer. With this new approach, researchers will now be able to rapidly distinguish the range of genetic changes that are causally linked to cancer (i.e. "driver" mutations) versus those with limited impact on cancer progression.

Scientists transplant stem cells from patients with limb-girdle muscular dystrophy into mice

Stem cells from patients with a rare form of muscular dystrophy have been successfully transplanted into mice affected by the same form of dystrophy, according to a new study published today in Science Translational Medicine.

Researchers discover protein required to regrow injured peripheral nerves

A protein required to regrow injured peripheral nerves has been identified by researchers at Washington University School of Medicine in St. Louis.

Simple sponge may hold clues about the evolution of the complex nervous system

UC Santa Barbara scientists turned to the simple sponge to find clues about the evolution of the complex nervous system and found that, but for a mechanism that coordinates the expression of genes that lead to the formation of neural synapses, sponges and the rest of the animal world may not be so distant after all.

New U-M hESC lines now available for federally-funded research

Six new human embryonic stem cell lines derived at the University of Michigan have just been placed on the U.S. National Institutes of Health's registry, making the cells available for federally-funded research.

Human-derived stem cells can spontaneously form optic cups and retina

Human-derived stem cells can spontaneously form the tissue that develops into the part of the eye that allows us to see, according to a study published by Cell Press in the 5th anniversary issue of the journal Cell Stem Cell.

Researchers identify two proteins that are required to maintain kidney stem cells

Studying mice and humans, researchers at Washington University School of Medicine in St. Louis and their collaborators in Paris have identified two proteins that are required to maintain a supply of stem cells in the developing kidney.

Effective ways of detecting onset of kidney disease

Research led by an Arizona State University biomedical engineer and physicist to find more effective ways of detecting the onset of kidney disease is getting support from the National Institutes of Health.

LILRB2 receptor plays an important role in keeping stem cells from differentiating

An immune-system receptor plays an unexpected but crucially important role in keeping stem cells from differentiating and in helping blood cancer cells grow, researchers at UT Southwestern Medical Center report today in the journal Nature.

Secreted vesicles play role in spread of cancer

Cancer researchers have known for well over a century that different tumor types spread only to specific, preferred organs. But no one has been able to determine the mechanisms of organ specific metastasis, the so-called "soil and seed" theory of 1889. New details that could help shed light on this hypothesis have been provided by a team of researchers from Weill Cornell Medical College, Memorial Sloan-Kettering Cancer Center, and their collaborators, proposing a new mechanism controlling cancer metastasis that offers fresh diagnostic and treatment potential.
