University of California study may shed light on human ability to adapt hypoxia

In an important study that may shed light on human ability to adapt to hypoxia, or inadequate levels of oxygen, researchers at the University of California, San Diego School of Medicine have proven that the genome of flies exposed to long-term hypoxia are changed to permanently affect gene expression.

Researchers identify PBRM1 gene mutation in one in three patients with common form of renal cancer

In a collaborative project involving scientists from three continents, researchers have identified a gene that is mutated in one in three patients with the most common form of renal cancer.

New Down syndrome non-invasive test for ‘mums-to-be’ on the horizon

According to experts a simple DNA test for Down syndrome could save nearly all pregnant women from invasive tests like amniocentesis. Usually 3% to 5% of pregnant women in the UK or some 30,000 women have to undergo invasive tests like amniocentesis that increases the risk of miscarriage to 1%. The new DNA blood test could bring this down to 0.1%, according to a study in the British Medical Journal.

New mechanisms of resistance to chemotherapy among leukemia patients

The interplay between a major tumor-suppressing gene, a truncated chromosome and two sets of microRNAs provides a molecular basis for explaining the less aggressive form of chronic lymphocytic leukemia, an international team of researchers reports today in the Jan. 4 edition of the Journal of the American Medical Association.

Single cellular crisis shatters chromosomes in cancer causation

Remarkable new research overthrows the conventional view that cancer always develops in a steady, stepwise progression. It shows that in some cancers, the genome can be shattered into hundreds of fragments in a single cellular catastrophe, wreaking mutation on a massive scale.

Chromosome shattering seen in two to three percent of all cancers

Most of the time cancer seems to creep up gradually over time; cells become premalignant, then increasingly abnormal before they become cancerous. But sometimes cancers seem to pop up as if out of nowhere. Now, researchers reporting in the January 7th issue of the journal Cell, a Cell Press publication, have new evidence to explain how that can happen.

Low levels of microbe-killing molecules improve survival rate of people with CGD

Investigators at the National Institutes of Health have observed that the survival rate of people with a rare immunodeficiency disease called chronic granulomatous disease is greatly improved when even very low levels of microbe-killing molecules are present.

BIOMICs oversees SGIker DNA Bank to know genetic heritage of Basque lineage

The BIOMICs Group, based at the Lucio Lascaray building in the álava/Araba campus of the University of the Basque Country, is specially known for overseeing the SGIker DNA Bank, not only undertaking this task, but also feeding data into the gene research bank and making good use of it for their own lines of research.

Study sheds light on how bacteria developed resistance to antibiotics

Studying how bacteria incorporate foreign DNA from invading viruses into their own regulatory processes, Thomas Wood, professor in the Artie McFerrin Department of Chemical Engineering at Texas A&M University, is uncovering the secrets of one of nature's most primitive immune systems.

Catalogs of fruit fly and roundworm's functional genomic elements

Scientists today published catalogs of the fruit fly and roundworm's functional genomic elements: DNA sequences in the genome that carry the instructions and determine which genes are turned on and off at various times in different cells.

Overexpression of Sox3 gene in mice causes XX male sex reversal

A team of researchers, led by Paul Thomas, University of Adelaide, Australia, has now determined that overexpression of the Sox3 gene in mice causes frequent XX male sex reversal.

Sequenom CMM authorizes SensiGene T21 LDT clinical validation study

Sequenom, Inc. today announced that the company's wholly-owned reference laboratory, the Sequenom Center for Molecular Medicine (Sequenom CMM), has authorized commencement of a pivotal clinical validation study. This validation study is designed to evaluate the clinical performance of the SensiGene T21 Laboratory Developed Test (LDT) for the detection of an overabundance in maternal blood of chromosome 21, which is associated with fetal chromosome 21 aneuploidy.

Male mice created without Y chromosome

University of Adelaide researchers are a step closer to unraveling the mysteries of human sexual development, following genetic studies that show male mice can be created without a Y chromosome - through the activation of an ancient brain gene.

Gene changes during brain development can lead to male genitalia formation in female embryo

Australian scientists have discovered that changes to a gene involved in brain development can lead to testis formation and male genitalia in an otherwise female embryo.

Research identifies two genetic variants that increase risk of endometriosis

Research published today identifies two genetic variants that increase the risk of developing endometriosis, a common gynaecological disease. The study provides clues to the origin of this often very painful condition, which has a significant impact on the quality of life of sufferers.

Dogs help understand primary ciliary dyskinesia

A dog is mankind's best friend : the old saying has once again been borne out through a medical discovery concerning the genetic origins of primary ciliary dyskinesia (PCD). In using dogs as a research model in the framework of the European LUPA project, a team from the University of Liège's GIGA-Research Unit has been able to bring to light new mutations in a specific gene responsible for the development of the disease in human beings.
