Role of hepatic STAT3 in brain-insulin action on hepatic glucose production

New research in Cell Metabolism identifies a key player in the body's ability to respond to insulin action in the brain by ratcheting down the export of blood sugar from the liver.

Caenorhabditis elegans helps unravel mechanisms of hunger

In research that may have implications for studying eating disorders in humans, a worm the size of a pinhead is helping researchers at UT Southwestern Medical Center unravel the mechanisms of hunger.

Researchers identify potential targets for more effective analgesic drugs with potentially fewer side effects

Studying mice, pain researchers at Washington University School of Medicine in St. Louis have identified two key components in the pain cascade that may provide targets for more effective analgesic drugs with potentially fewer side effects

Inflammation cuts both ways

Inflammation cuts both ways. When invaded by an infectious agent, for example, the body calls on the forces of inflammation to fight and defeat the intruder.

Link between bacteria found in the mouth and the amniotic fluid of a woman in preterm labor

A 37-year-old-mother, who gave birth to a low-weight preemie at 24 weeks, exhibited the first-found link in a human between bacteria found in the mouth and the amniotic fluid of a woman in preterm labor.

Ingredient in red peppers inhibits prostate cancer in laboratory studies

Capsaicin is the pungent ingredient in red peppers and is presently used as a topical pain reliever. Now, a new study shows it may be justified to evaluate capsaicin for inhibiting prostate cancer (CaP) in patients.

Higher self awareness of memory difficulties may be associated with brain function decline over time

Published in the April issue of the Archives of General Psychiatry, the study offers a greater understanding of how different types and varying degrees of memory complaints may relate to brain function decline, a finding that may lead to early treatment interventions for people who could develop Alzheimer's disease.

Genome evolution in gibbons erased fat gene

Scientists from The University of Tokyo have discovered that gibbons, arboreal primates that inhabit the jungles of Southeast Asia, do not carry a major obesity gene that is present in the genomes of all other primates, including humans.

Genetic clues to longevity

In a new study, Drs. Gil Atzmon and Nir Barzilai at the Albert Einstein College of Medicine of Yeshiva University have found that people harbor alleles--alternative forms of a gene--that confer the same sort of longevity advantage.

Nrf2 gene findings may offer therapeutic potential for sepsis treatment

Disruption of a single gene, Nrf2, plays a critical role in regulating the body's innate immune response to sepsis and septic shock, according to a study by a research team led by Shyam Biswal, PhD, at the Johns Hopkins Bloomberg School of Public Health.

Johns Hopkins scientists identify genes in fruitflies that may shed light on human cancer spread

By searching through all the genes in the fruitfly genome, Johns Hopkins scientists have identified those required for a certain type of cell migration and simultaneously captured a global view of all the genes turned on when cells are on the move.

Yellow pigment that sits on the retina focus of macular degeneration research

Whether a tiny yellow pigment is the main thing standing between many older people and macular degeneration is under study at the Medical College of Georgia.

Researchers narrow search for effective prostate cancer biomarkers

Researchers at Mayo Clinic have narrowed the search for effective prostate cancer biomarkers (genetic variations that point to a specific disease or condition), identifying changes in the expression of genes of the whole genome closely correlated to prostate cancer development and progression.

Promising new targets for Alzheimer's drug therapies

An enzyme previously associated with preventing the dementia of Alzheimer's disease now appears to play an even bigger role in safeguarding against the disease, bringing the promise of new targets for drug therapies.

People with very agile minds tend to have a very agile cortex

Youth with superior IQ are distinguished by how fast the thinking part of their brains thickens and thins as they grow up, researchers at the National Institute of Mental Health (NIMH) have discovered.

HOXB13 and IL17BR genes predict outcome for breast cancer patients

The 2-gene expression profile of HOXB13 and IL17BR in a woman's breast cancer predicts risk of recurrence in node-negative patients treated with tamoxifen.

Immune response protects against brain tumor development

In their quest to determine whether immune system surveillance guards against brain tumor development, researchers at The University of Texas M. D. Anderson Cancer Center have found that allergies and asthma that stimulate inflammation may be protective, but use of antihistamines to control the inflammation could eliminate that protection.

Mitochondria induce nuclear deformation

In a paper being presented in two American Physiological Society sessions at Experimental Biology 2006, a joint Estonian-French team demonstrated "for the first time that mitochondria are able to induce nuclear deformation, suggesting that mitochondria may mechanically regulate nuclear function."

Proteomics yields new drug targets for treating cardiogenic shock

When it comes to cell signaling and bioregulation, it's tough to find a more important molecule than nitric oxide (NO). Dysfunction of NO-mediated signaling is thought to be a culprit in lethal cardiovascular conditions such as angina, and septic, cardiogenic and hemorrhagic shock; it may play a role in many other illnesses as well.

Gene key to infection-fighting immune cells identified

Every time the human body encounters a virus, bacteria or other infectious agent, immune cells called B-lymphocytes multiply in lymph nodes and then swing into action to fight off the intruders.
