TET proteins needed to maintain genome instability, say researchers

Members of the TET (short for ten-eleven translocation) family have been known to function as tumor suppressors for many years, but how they keep a lid on the uncontrolled cell proliferation of cancer cells had remained uncertain. Now, researchers at the La Jolla Institute for Allergy and Immunology demonstrate that TET proteins collectively constitute a major class of tumor suppressors and are required to maintain genome instability.

Genetic variations associated with increased risk for osteonecrosis in young ALL patients

Variations in genes involved in normal bone development are associated with an 8- to 15-fold increased risk for osteonecrosis in young patients with acute lymphoblastic leukemia (ALL), according to research led by St. Jude Children's Research Hospital and Children's Oncology Group investigators.

New method may extend use of noninvasive prenatal testing to detect chromosomal abnormalities

Researchers at the University of California, San Diego School of Medicine developed a method to expand the types of chromosomal abnormalities that noninvasive prenatal testing (NIPT) can detect. The study, published November 9 by Proceedings of the National Academy of Sciences, uses a semiconductor sequencing platform to identify small chromosomal deletions or duplications, such as occur in Cri du Chat Syndrome and DiGeorge Syndrome, with a simple blood test from the expectant mother.

Glan Clwyd Hospital N Wales invest in Esaote's G-Scan MRI unit for weight-bearing scanning

Glan Clwyd Hospital in North Wales has become the first publicly-funded hospital in the UK to invest in Esaote’s G-scan Brio, an open, weight-bearing MRI unit for musculoskeletal scanning. In an innovative move, the hospital can now scan patients in any position, from standing vertically to the traditional supine postition laying flat.

Different Crohn's disease treatments affect children's gut microbes in distinct ways

Different treatments for Crohn's disease in children affects their gut mi-crobes in distinct ways, which has implications for future development of microbial-targeted therapies for these patients, according to a study led by researchers from the Perelman School of Medicine at the University of Pennsylvania.

Study seeks to understand how the human brain changes in space

In space, there is no "up" or "down." That can mess with the human brain and affect the way people move and think in space. An investigation on the International Space Station seeks to understand how the brain changes in space and ways to deal with those changes.

Mutation that increases sphingolipid levels can lead to neurodegeneration

A mutation that increases the level of a special class of sphingolipids--molecules important to cell structure and signaling--can lead to neurodegeneration due to problems with neuronal membranes, reports a research team led by Jackson Laboratory Research Scientist Lihong Zhao, Ph.D. and Professor Patsy Nishina, Ph.D.

Jumping genes: a marker for early cancer diagnosis? An interview with Dr Kazazian

In the genome of every human being, there are about 80-100 active LINE-1s that are capable of mobilizing by a copy and paste mechanism to a new location in the genome.

Unlocking the genes behind antibiotic resistance: an interview with Professor Romesberg

Bacteria are very, very diverse. This is why their susceptibility to different antibiotics can be very different. It also makes the tools they have to evolve resistance in many cases different.

Desmoplasmic melanoma may possess unprecedented burden of gene mutations, say UCSF scientists

A rare, deadly form of skin cancer known as desmoplasmic melanoma (DM) may possess the highest burden of gene mutations of any cancer, suggesting that immunotherapy may be a promising approach for treatment, according to an international team led by UC San Francisco scientists. One of these mutations, never before observed in any cancer, may shield nascent DM tumors from destruction by the immune system and allow further mutations to develop.
