Clock Stars: Astrocytes Keep Time for Brain, Behavior

Star-shaped cells called astrocytes, long considered boring, “support cells,” are finally coming into their own. To everyone’s surprise they even play an important role in the body’s master clock, which schedules everything from the release of hormones to the onset of sleepiness.

Research Suggests a Possible Role for a Storm of “Jumping Genes” in ALS

By inserting an amyotrophic lateral sclerosis (ALS)-linked human gene called TDP-43 into fruit flies, researchers at Stony Brook University and Cold Spring Harbor Laboratory discovered a potential role for ‘transposons’ in the disease.

Two New ERC Advanced Grants for the IMP Vienna

Applications by the IMP, the Research Institute of Molecular Pathology in Vienna, were 100% successful in the latest call of the European Research Council ERC. Over the coming five years, projects by Senior Scientists Meinrad Busslinger and Elly Tanaka will be funded with 4.8 million euros.

Scientists Get Closer Look at Living Nerve Synapses

SynapseKlyachko.jpg

The brain hosts an extraordinarily complex network of interconnected nerve cells that are constantly exchanging electrical and chemical signals at speeds difficult to comprehend. Now, scientists at Washington University School of Medicine in St. Louis report they have been able to achieve — with a custom-built microscope — the closest view yet of living nerve synapses.

Surprising Culprit in Nerve Cell Damage Identified

In new research, scientists at Washington University School of Medicine in St. Louis have implicated a specific molecule in the self-destruction of axons, the wiring of the nervous system. Understanding just how that damage occurs may help researchers find a way to halt it.

Researchers Identify First Evidence of Epigenetic Role in Breast Cancer

Researchers from Memorial Sloan Kettering Cancer Center (MSK) have identified, for the first time, an epigenetic mechanism promoting breast cancer. The team found that inhibition of the PI3K pathway leads to activation of ER-dependent transcription through the epigenetic regulator KMT2D. These findings provide a rationale for epigenetic therapy in patients with PIK3CA-mutant, ER-positive breast cancer. While epigenetic factors have been known to play an important role in various cancers such as leukemia and lymphoma, this is the first evidence found in breast cancer.

New Study Finds That Most Cancer Mutations are Due to Random DNA Copying ‘Mistakes’

Johns Hopkins Kimmel Cancer Center scientists report data from a new study providing evidence that random, unpredictable DNA copying “mistakes” account for nearly two-thirds of the mutations that cause cancer. Their research is grounded on a novel mathematical model based on DNA sequencing and epidemiologic data from around the world.
