Chromosome aberrations happen in pairs when it comes to cancer

A healthy genome is characterized by 23 pairs of chromosomes, and even a small change in this structure - such as an extra copy of a single chromosome - can lead to severe physical impairment. So it's no surprise that when it comes to cancer, chromosomal structure is frequently a contributing factor, says Prof. Ron Shamir of the Blavatnik School of Computer Science at Tel Aviv University.

Artificial testes being developed to help infertile men produce sperm

Californian researchers are trying to create an artificial testicle that will produce human sperm. Dr. Paul Turek, director of the Turek Clinic in San Francisco, which specializes in male infertility, said the goal is not to create a testicular implant for men, but a “sperm-making biological machine” that will help scientists learn more about just what causes male infertility. “We’re trying to recreate the process of sperm production in a three-dimensional system,” Turek said. “Simple laboratory conditions can’t get it done in humans. Our concept is to actually recreate the testicle itself.”

MSC-mediated RNAi transfer holds promise for Huntington's disease

A team of researchers at the UC Davis Institute for Regenerative Cures has developed a technique for using stem cells to deliver therapy that specifically targets the genetic abnormality found in Huntington's disease, a hereditary brain disorder that causes progressive uncontrolled movements, dementia and death.

Inherited mutation links exploding chromosomes to cancer

An inherited mutation in a gene known as the guardian of the genome is likely the link between exploding chromosomes and some particularly aggressive types of cancer, scientists at the European Molecular Biology Laboratory (EMBL), the German Cancer Research Centre (DKFZ) and the University Hospital, all in Heidelberg, Germany, have discovered.

Researchers reveal role of micronuclei in cancer process

They are the Robinson Crusoes of the intracellular world -- lone chromosomes, whole and hardy, stranded outside the nucleus where their fellow chromosomes reside. Such castaways, each confined to its own "micronucleus," are often found in cancer cells, but scientists haven't known what role, if any, they play in the cancer process.

Study explains gender-related incidence of liver cancer

Men are four times more likely to develop liver cancer compared to women, a difference attributed to the sex hormones androgen and estrogen. Although this gender difference has been known for a long time, the molecular mechanisms by which estrogens prevent -- and androgens promote -- liver cancer remain unclear.

Earlier detection of Fragile X syndrome made possible

Now families children with fragile X syndrome may have a chance of earlier detection and intervention. The Murdoch Children's Research Institute breakthrough could allow newborn screening of the world's most common cause of inherited developmental disability. The research findings were published in the journal Clinical Chemistry.

Novel technique accurately maps gene-regulation proteins

A novel technique has been developed and demonstrated at Penn State University to map the proteins that read and regulate chromosomes -- the string-like structures inside cells that carry genes.

GSA honors researchers, educators for distinguished service in the field of genetics

The Genetics Society of America (GSA) is pleased to announce the 2012 recipients of its five awards for distinguished service in the field of genetics. The recipients of these awards were nominated and selected by their colleagues.

Source of infantile epilepsy found in a gene

Researchers from Adelaide have discovered a 20-year mystery about a type of epilepsy in infants. It is caused by a single mutation in one gene they found. The discovery will allow for better screening, diagnosis and prediction of the risk of seizures for sufferers of benign familial infantile epilepsy, the researchers say.

NimbleGen Sequence Capture 385K array identifies gene mutations linked with hereditary hearing loss

Hereditary hearing loss is the most common sensory disorder in humans. A German research team led by Ingo Kurth from the Institute of Human Genetics at the University Hospital Jena, Germany, used a number of different methods, including Roche's NimbleGen Custom Sequence Capture 385K array to identify the gene mutated in the disease locus of the X-chromosome of a Spanish family with hereditary hearing loss.

Kedem commences development of Gleevec to treat CML in children and adults

Kedem Pharmaceuticals Inc., a specialty pharmaceutical company with focus on sublingual drug delivery system is pleased to announce that has initiated the development of Gleevec.

Scientists identify rare genetic mutation linked to prostate cancer

After a 20-year quest to find a genetic driver for prostate cancer that strikes men at younger ages and runs in families, researchers have identified a rare, inherited mutation linked to a significantly higher risk of the disease.

Researchers identify mechanism that makes retinoblastoma so aggressive

New findings from the St. Jude Children's Research Hospital - Washington University Pediatric Cancer Genome Project (PCGP) have helped identify the mechanism that makes the childhood eye tumor retinoblastoma so aggressive. The discovery explains why the tumor develops so rapidly while other cancers can take years or even decades to form.

DNA may be used to predict lifespan: Study

Researchers may soon be able to predict how long a person will live based on their genetics. This could result from the discovery by a University of Glasgow team in Scotland showing that telomere length on the ends of DNA in their genes in early-life predicts life spans.

Erlotinib better for treatment of non-small cell lung cancers

Researchers at Johns Hopkins have shown that DNA changes in a gene that drives the growth of a form of lung cancer can make the cancer's cells resistant to cancer drugs.

Aria's non-invasive test more effective in detecting Trisomy 18 & 21

Aria Diagnostics, a molecular diagnostics company, today announced publication of data supporting a directed, non-invasive approach to cell-free DNA (cfDNA) analysis in maternal blood for evaluation of two common fetal trisomies linked to genetic disorders.

Scientists identify two genes involved in major symptoms of MeCP2 duplication disorder

The anxiety and behavioral issues associated with excess MeCP2 protein result from overexpression of two genes (Crh [corticotropin-releasing hormone] and Oprm 1 [mu-opioid receptor MOR 1]), which may point the way to treating these problems in patients with too much of the protein, said Baylor of Medicine scientists in a report that appears online in the journal Nature Genetics.

New imaging technology may pinpoint subtle aberrations in molecular biosignature of cancer

Despite advances in both the diagnosis and treatment of breast cancer, the disease remains a leading worldwide health concern.

Researchers identify candidate genes for histiocytoid cardiomyopathy

Researchers are closing in on a rare genetic disorder causing a heart condition in infants. Histiocytoid cardiomyopathy (HC) often causes sudden death before a child reaches 2 years of age. Gene analysis is helping to narrow the many theories surrounding the genetic basis of HC.
