Securin is not required for chromosomal stability in human cells

A critical aspect of cell division, or mitosis, is that the progeny cells must receive the full complement of chromosomes.

Common garden plant may hold cure for leukemia

Scientists in the U.S. believe they have identified a new pathway in the progression of chronic myelogenous leukemia (CML).

Dog gene map may help explain human diseases

U.S. scientists say a detailed analysis of the dog genome answers such questions as how dogs of a different breed still belong to the same species, and may also explain some aspects of human health and biology.

Cancer, genes and broccoli

People who gain less protection from cancer by eating broccoli may be able to compensate for the difference in their genetic make-up by eating 'super broccoli', a variety with higher levels of the active plant chemical sulforaphane, or by eating larger portions.

Genetic testing for Parkinson disease, is there a point?

Should we start being genetically tested for Parkinson’s disease (PD)? According to research just published in the December issue of the "journal Movement Disorders" this might be a possibility in the future if you belong to a family affected by G2019S, a genetic mutation responsible for some PD cases.

New type of sulfite reductase

Biswarup Mukhopadhyay and Eric Johnson from the Virginia Bioinformatics Institute at Virginia Tech have discovered a novel enzyme that represents an ancient detoxification system and provides a clue to the development of early metabolism on earth.

Hippocampal myo-inositol and cognitive ability in adults with Down Syndrome

Researchers from the Institute of Psychiatry at King's College London have identified a molecule that could be targeted to treat the cognitive impairment in people with Down syndrome.

MicroRNAs greatly influence the evolution of genes

RNA continues to shed its reputation as DNA's faithful sidekick. Now, researchers in the lab of Whitehead Institute Member David Bartel have found that a class of small RNAs called microRNAs influence the evolution of genes far more widely than previous research had indicated.

Liver plays crucial role in iron metabolism

A new study in the December Cell Metabolism reveals an unexpected connection between a tumor suppressor gene in the liver and the normally careful control over the amount of iron absorbed from the diet.

New cancer detection method

University of Florida researchers say they are a step closer to a technique to easily detect a wide variety of cancers before symptoms become apparent.

Stem cells may cause some forms of bone cancer

The researchers are the first to identify a population of cells with characteristics of adult and embryonic stem cells in cultures derived from biopsies of patients' bone tumors. They describe their findings in the medical journal Neoplasia.

Transport mechanisms for serotonin

Researchers at The Forsyth Institute have discovered that the transport mechanisms for serotonin - the chemical substance involved in transmitting signals between neurons, and which has a role in anxiety and mood disorders - play a key role in determining where organs are positioned in the body during embryonic development.

Recording the formation of a memory trace

Memory formation follows a dynamic pattern, allowing for retrieval from different areas of the brain, depending on when an organism needs to remember, said a researcher at Baylor College of Medicine.

Ack1 molecule stimulates the aggressive growth of prostate cancer

The molecule, Ack1, a member of the growth-promoting tyrosine kinase gene family, stimulates tumor formation in part by signaling prostate cells to rid themselves of a tumor-suppressor protein. Normally, this suppressor protein would inhibit rapid cell growth by signaling the cell to destroy itself.

Fibroblast research could lead to alternatives to implanted electronic pacemakers

In guinea pig experiments, Johns Hopkins scientists fused common connective tissue cells taken from lungs with heart muscle cells to create a safe and effective biological pacemaker whose cells can fire on their own and naturally regulate the muscle's rhythmic beat.

LEDGF protein controls the location of HIV integration in human cells

A human DNA-associated protein called LEDGF is the first such molecule found to control the location of HIV integration in human cells, according to researchers at the University of Pennsylvania School of Medicine.

Genetics play a part in the inability to stop caffeine use

A study led by Johns Hopkins investigators has shown that women with a serious caffeine habit and a family history of alcohol abuse are more likely to ignore advice to stop using caffeine during pregnancy.

Researchers link microRNA - miR 196 - to limb development

A tiny strand of molecules plays a role in how our arms and legs develop and grow - a finding that sheds light on perplexing bits of material once dismissed as genetic "junk," say scientists at the University of Florida and Harvard University.

Researchers move in on novel therapeutics to inhibit melanoma

Northwestern University researchers have developed a novel, three-dimensional model that allows scientists to observe how interacting with the microenvironment of metastatic melanoma cells induces normal skin cells to become similar to aggressive cancer cells that migrate and spread throughout the body.

Unexpected link between muscular dystrophy and muscle wasting associated with cancer

A new study provides important insight into the mechanisms of a muscle wasting disorder that interferes with treatment for cancer and has a negative impact on patient survival.
