New findings about how prostate cancer cells are able to resist hormone treatment and defy death may lead to more effective drug treatments.   view more (2006-07-31)

Absence of critical protein linked to infertility
Researchers at the University of Illinois at Urbana-Champaign report that experiments involving mice - to be detailed in the Proceedings of the National Academy of Sciences - indicate that the transcription factor protein C/EBPb must be present in the uterus for pregnancy to occur.   view more (2006-01-17)

Plague agent helps UT Southwestern researchers find novel signaling system in cells
The bacterium that causes bubonic plague would seem unlikely to help medical scientists, but researchers at UT Southwestern Medical Center have harnessed it to uncover a new regulatory mechanism that inhibits the immune system.   view more (2006-05-26)

Some like it hot! Structure of receptor for hot chili pepper and pain revealed
You can now not only feel the spicy kick of a jalapeno pepper, you can also see it in full 3D, thanks to researchers at Baylor College of Medicine in Houston.   view more (2008-05-20)

Penn researchers discover initial steps in the development of taste
Of the five senses, taste is one of the least understood, but now researchers at the University of Pennsylvania School of Medicine have come one step closer to understanding how the sense of taste develops.   view more (2006-12-06)

UIC researchers show how cancer-preventing foods work
Researchers at the University of Illinois at Chicago are unraveling the biochemical mechanism by which functional foods combat cancer.   view more (2005-07-11)

OHSU lab finds meth receptor that could lead to therapy
A recently discovered signaling system in the brain has just been shown to be turned on by methamphetamine, an Oregon Health & Science University study found.   view more (2007-04-19)

CSHL scientists trace causal link between a tumor suppressor gene and liver cancer
Scientists at Cold Spring Harbor Laboratory (CSHL) have taken the search for cancer-causing genes an important step forward. In a newly published paper, they confirm that a gene called DLC1 is a tumor suppressor. They have demonstrated in living mice that its deletion, inactivation or loss... view more (2008-06-04)

New role for sugars: Research shows connections between sugar modifications in cells and cancer
In a ground-breaking study published in the top journal, Cell, Dr. James Dennis, senior investigator at the Samuel Lunenfeld Research Institute at Mount Sinai Hospital, has discovered a new role for sugars on proteins.   view more (2007-04-06)

Same process discovered to both form skeleton and protect it for life
A protein signaling pathway recently discovered to guide the formation of the skeleton in the fetus also keeps bones strong through adult life, according to two papers published recently in the journal Nature Medicine.   view more (2008-03-13)

A key to male fertility
Until now, mutations of the LH hormone receptor were the only explanation known for sexual precocity in boys. A team at the Institute of Genetics and Molecular and Cellular Biology (IGBMC, CNRS / Inserm / Université Louis Pasteur de Strasbourg)), in collaboration with researchers at the... view more (2007-03-05)

New light-sensing ability discovered in disease-causing bacteria
The bacteria that cause brucellosis can sense light and use the information to regulate their virulence, according to a study in the August 24 issue of the journal Science.   view more (2007-08-24)

Wisconsin researchers describe how digits grow
Researchers at the University of Wisconsin School of Medicine and Public Health (SMPH) are wagging a finger at currently held notions about the way digits are formed.   view more (2008-03-12)

Chloroplast f and m Thioredoxins Discovered in Nonphotosynthetic Tissues
Thioredoxins (TRXs) are a large family of small proteins that function in multiple metabolic processes in all living organisms. They are a good example of proteins that have diversified throughout evolution, probably from one ancestral protein that arose in ancient cyanobacteria.   view more (2007-10-16)

Cilia: small organelles, big decisions
Johns Hopkins researchers say they have figured out how human and all animal cells tune in to a key signal, one that literally transmits the instructions that shape their final bodies.   view more (2007-10-04)

Novel enzyme inhibitor paves way for new cancer drug
Combining natural organic atoms with metal complexes, scientists at The Wistar Institute have developed a new type of enzyme inhibitor capable of blocking a biochemical pathway that plays a key role in cancer development.   view more (2008-05-16)

Blood cells linked to heart attacks, other inflammatory diseases
Two human blood cells that help fight blood loss, infection, and inflammation are responsible as well for starting a series of molecular events that results in overproduction of Cox-2, an enzyme involved in heart attack, stroke, atherosclerosis, and other inflammatory diseases.   view more (2006-10-09)

MIT uncovers key blood protein
Scientists working in the only lab at MIT doing hematology research have uncovered a protein that plays a key role in the recycling of iron from blood.   view more (2007-10-12)

New fruit fly protein illuminates circadian response to light
Researchers at the University of Pennsylvania School of Medicine have identified a new protein required for the circadian response to light in fruit flies.   view more (2006-06-30)

Jefferson scientists find protein potential drug target for treatment-resistant prostate cancer
Scientists at Jefferson's Kimmel Cancer Center in Philadelphia have found that a signaling protein that is key to prostate cancer cell growth is turned on in nearly all recurrent prostate cancers that are resistant to hormone therapy.   view more (2008-01-02)

Insects evolved radically different strategy to smell
Darwin's tree of life represents the path and estimates the time evolution took to get to the current diversity of life. Now, new findings suggest that this tree, an icon of evolution, may need to be redrawn.   view more (2008-04-14)

Discovery opens door to 'personalized' asthma therapy
In the last few years, "personalized medicine"- using genetic or other molecular biology-based diagnostic tests to customize treatment for a particular patient - has emerged as a powerful new tool for health care.   view more (2008-01-18)

Researchers at Illinois explore queen bee longevity
The queen honey bee is genetically identical to the workers in her hive, but she lives 10 times longer and - unlike her sterile sisters - remains reproductively viable throughout life.   view more (2007-05-09)

Study finds foul owls use feces to show they are in fine feather
Some years ago, within the Department of Conservation Biology of the Estación Biológica de Doñana (EBD-Consejo Superior de Investigaciones Científicas; Seville, Spain), a recently established group (colloquially named the Night Ecology Group) started to explore the... view more (2008-08-20)
