Scientists explore black box of genome biology

Scientists at Florida State University, Baylor College of Medicine and the Broad Institute of Harvard and MIT have broken ground in a little-understood area of human genetics.

UC Davis scientists show how cells control DNA synthesis in mitochondria

Aging, neurodegenerative disorders and metabolic disease are all linked to mitochondria, structures within our cells that generate chemical energy and maintain their own DNA. In a fundamental discovery with far-reaching implications, scientists at the University of California, Davis, now show how cells control DNA synthesis in mitochondria and couple it to mitochondrial division.

Researchers discover new biological pathway involved in Alzheimer's disease

Researchers have identified a new biological pathway involved in Alzheimer's disease. In experiments using fruit flies, blocking the pathway reduced the death of brain cells, suggesting that interfering with the pathway could represent a promising new strategy to treat the disease in human patients.

Researchers study how skin stem cells respond to forces

All cells share the same genetic code, no matter if they are skin or brain cells. However, these cells are exposed to very different types of mechanical environments and mechanical stresses.

JAX researchers find precise, reliable way to identify leukemia cells of origin

Every cancer starts with a single cell, and Jackson Laboratory researchers have found a precise and reliable way -- whole-genome profiling of open chromatin -- to identify the kind of cell that leads to a given case of leukemia, a valuable key to cancer prognosis and outcome.

Researchers discover mechanism of gene silencing in hormone-dependent breast cancer cells

Sometimes, the silencing of a gene is as important as its activation. Nonetheless, up to now, most studies on hormone-mediated gene regulation have focused on researching the factors that influence the activation of certain genes. Little attention has been paid to gene silencing.

Mitochondrial stress can trigger tumor-related metabolic shifts, study finds

Cancerous tumors must be fed. Their unregulated growth requires a steady stream of blood flow and nutrients. Thus, one way that researchers have tried to wipe out cancer is to target cells undergoing the metabolic shifts that enable a tumor's rapid growth.

Regular marijuana use impacts the brain's natural response to rewards

Most people would get a little 'rush' out of the idea that they're about to win some money.

Researchers identify non-coding RNA NEAT1 as potential drug target to combat cancer

A team of researchers led by professor Jean-Christophe Marine has identified NEAT1, a non-coding RNA, as a potential therapeutic target in the fight against cancer.

New supplement could help reduce urge to consume high-calorie foods

Eating a type of powdered food supplement, based on a molecule produced by bacteria in the gut, reduces cravings for high-calorie foods such as chocolate, cake and pizza, a new study suggests.

Scientists investigate molecular mechanisms that regulate STAT3 activity

Hokkaido University scientists are getting closer to understanding the function of a protein involved in vital cellular processes. This may lead to the discovery of drugs that can treat some cancers and autoimmune disorders.

New bioinformatics tool can analyse 40,000 proteins per minute

Biology and computing have joined forces to create a piece of software that analyses mutations in proteins; these mutations are potential inducers of diseases, such as cancer.

Researchers determine how Ki-67 protein disperses chromosomes in dividing cells

Billions of your cells divide every day. Cell division fuels growth and also replaces short-lived cells in some organs, like your skin, blood, and gut.

Researchers reveal novel mechanism by which viral protein VII suppresses immune alarm signals

Viruses must avoid a host's immune system to establish successful infections—and scientists have discovered another tool that viruses use to frustrate host defenses.

Tiny doses of anti-HIV drug may be effective for treating Alzheimer's disease

For a promising pathway to treating Alzheimer's patients, "aim here." That's what National Institute of Standards of Technology researchers advised collaborators hunting for molecules that, by linking to a normally occurring enzyme, rev up the brain's capacity for clearing cholesterol--a boost associated with improvements in memory and other benefits in animal studies.

Why does appetite loss occur during illness? An interview with Prof. Conti and Prof. Francesconi

Appetite, as a word, come from the Latin appetitus, meaning "desire for.” Therefore, appetite can be defined as a pleasurable sensation or the desire to eat. This sensation is coordinated by several brain areas associated with reward processing such amygdala, hippocampus, ventral pallidum, nucleus accumbens and striatum, and others.
