Cancer-causing fusion protein works by silencing tumor suppressor gene IL-2Rγ

Mariusz A. Wasik, MD, professor of Pathology and Laboratory Medicine, and Qian Zhang, MD, PhD, research assistant professor, both from the Perelman School of Medicine at the University of Pennsylvania, and their colleagues, found that a cancer-causing fusion protein works by silencing the tumor suppressor gene IL-2R common gamma-chain.

Flatworms provide new insight into organ regeneration, evolution of mammalian kidneys

Our bodies are perfectly capable of renewing billions of cells every day but fail miserably when it comes to replacing damaged organs such as kidneys. Using the flatworm Schmidtea mediterranea-famous for its capacity to regrow complete animals from minuscule flecks of tissue-as an eloquent example, researchers at the Stowers Institute for Medical Research demonstrated how our distant evolutionary cousins regenerate their excretory systems from scratch.

New genetic cause of retinitis pigmentosa

Combining the expertise of several different labs, University of Iowa researchers have found a new genetic cause of the blinding eye disease retinitis pigmentosa (RP) and, in the process, discovered an entirely new version of the message that codes for the affected protein.

New study focuses on Anopheles gambiae to prevent spread of malaria

A female mosquito cannot tell if the male that she has mated with is fertile or 'spermless' and unable to fertilise her eggs, according to a new study from scientists at Imperial College London.

Genetically altered spermless ‘mozzies’ to combat malaria

In a fresh new attempt to combat malaria, researchers have developed another way to reduce the numbers of the malaria-spreading blood-suckers: introduce genetically altered spermless males into the population.

Response Genetics second quarter total revenue increases 18.8% to $6.7 million

Response Genetics Inc., a company focused on the development and sale of molecular diagnostic tests for cancer, today announced its consolidated financial results and business progress for the second quarter ended June 30, 2011.

Kaan Medikal to distribute Saladax's My5-FU diagnostic test in Turkey

Saladax Biomedical, Inc., a privately held company developing and commercializing novel diagnostic assays to achieve the promise of personalized medicine for new and existing therapeutics, announced today that Kaan Medikal will serve as the exclusive distributor of Saladax's My5-FU diagnostic test throughout the Turkish market.

New study supports DNA-based 'biomarker' blood test for prostate cancer screening

A new study supports the use of a DNA-based "biomarker" blood test as a complement to the prostate-specific antigen (PSA) test currently offered to screen men for prostate cancer. University of Cincinnati (UC) researchers report their findings online ahead of print in the British Journal of Cancer.

Researchers discover gene variant linked to meningiomas

The causes of brain tumours have been hard to discern in most cases. But Umeå researchers have previously identified an inherited predisposition for brain tumours, and now, in an international collaboration, they have also discovered a genetic variation that increases the risk of a certain type of brain tumour, called meningiomas.

Affymetrix announces commercialization of next-generation human transcriptome array

Affymetrix, Inc. today announced commercialization of the next-generation human transcriptome array demonstrated by Stanford University researchers to be superior to mRNA sequencing (RNA-Seq) in gene expression profiling studies.

Schizophrenia not always inherited – Genetic links found

Researchers have found that more than half the cases of non-hereditary or sporadic schizophrenia are caused by “new” protein-altering gene mutations. These mutations are new genetic errors that appear in patients but not in either of their parents, the researchers explained in the report published in the Aug. 7 online edition of the journal Nature Genetics.

Ovarian cancer gene discovered

A new study finds that around one woman in 70 is at risk of developing ovarian cancer, which claims more than 4,200 lives a year and this could be attributed to a faulty RAD15D gene. The gene raised the risk to one in 11.

NHS doctors’ use of genetic tests leading to infringement of patent rights

NHS doctors are in trouble for over use of diagnostic genetic tests as these infringe upon patents. The British law now recognizes patents on the application of DNA discoveries. But doctors developing genetic tests in NHS hospitals tend to pay no heed to intellectual property.

Researchers use SNAP technology to assess fetal gene expression in amniotic fluid

Researchers have demonstrated the feasibility of focused fetal gene expression analysis of target genes found in amniotic fluid using Standardized NanoArray PCR (SNAP) technology.

De novo mutations account for 50% of sporadic cases of schizophrenia

Columbia University Medical Center researchers have shown that new, or "de novo," protein-altering mutations—genetic errors that are present in patients but not in their parents—play a role in more than 50 percent of "sporadic" —i.e., not hereditary—cases of schizophrenia.

Women with RAD51D gene fault more likely to develop ovarian cancer

Cancer Research UK-funded scientists have discovered that women who carry a faulty copy of a gene called RAD51D have almost a one in 11 chance of developing ovarian cancer, the most significant ovarian cancer gene discovery for more than a decade, reveals a study in Nature Genetics1 today.

Diet and genetics dictate adult jaw shape

Researchers at Johns Hopkins found that use over time and not just genetics informs the structure of jaw bones in human populations. The researchers say these findings may be used to predict the diet of an ancient population, even if little evidence exists in the fossil record. It can also make it easier for scientists to pinpoint the genetic relationship between fossils.
