Study suggests Fanconi Anemia and Bloom's Syndrome proteins may act in common DNA repair pathway

A new study establishes a molecular link that bridges two rare inherited disorders and explains why these diseases result in genetic instability. The research, published by Cell Press in the December 24th issue of the journal Molecular Cell, may lead to a better understanding of the complex mechanisms that enable cells to repair damaged DNA.

Researchers at Stanford University School of Medicine identify a critical component, Jarid2

Like a child awaiting the arrival of Christmas, embryonic stem cells exist in a state of permanent anticipation. They must balance the ability to quickly become more specialized cell types with the cellular chaos that could occur should they act too early (stop shaking those presents, kids!).

Test tube experiments show slight changes in protein chemistry can eliminate Huntington's disease in mice

In Huntington's disease, a mutated protein in the body becomes toxic to brain cells. Recent studies have demonstrated that a small region adjacent to the mutated segment plays a major role in the toxicity. Two new studies supported by the National Institutes of Health show that very slight changes to this region can eliminate signs of Huntington's disease in mice.

Discovery of protein transport promotes new research on spinal defects

Spinal cord disorders like spina bifida arise during early development when future spinal cord cells growing in a flat layer fail to roll up into a tube. In the Dec. 6 issue of Nature Cell Biology, researchers from the Johns Hopkins University School of Medicine team with colleagues at the University of California, Berkeley to report a never-before known link between protein transport and mouse spinal cord development, a discovery that opens new doors for research on all spinal defects.

Scientists uncover a central process in memory encoding

Scientists at UC Santa Barbara have made a major discovery in how the brain encodes memories. The finding, published in the December 24 issue of the journal Neuron, could eventually lead to the development of new drugs to aid memory.

E2F1 transcription factor inhibition reduces EGFR expression and invasive potential of melanoma cells

Inhibition of transcription factor E2F1 reduced epidermal growth factor receptor (EGFR) expression and reduced the invasive potential but not proliferation of metastatic melanoma cells, according to a brief communication published online December 23 in the Journal of the National Cancer Institute.

Key molecular switch linked to HD identified

Scientists have identified a key molecular switch that may drive the onset of Huntington's disease (HD), an incurable neurodegenerative disorder that leads to severe disruptions in muscle coordination and cognitive function. The research, published by Cell Press in the December 24 issue of the journal Neuron, enhances the understanding of HD pathogenesis and may direct new strategies for treating this devastating brain disease.

Potential new therapeutic option for prevention of PD-associated neuropathology

Scientists have identified a synergistic interaction that disrupts normal intracellular transport mechanisms and leads to the accumulation of neuron-damaging clumps of protein associated with Parkinson's disease (PD), a neurodegenerative disorder that is characterized by a specific loss of neurons in the midbrain and brainstem. The research, published by Cell Press in the December 24 issue of the journal Neuron, identifies a new potential therapeutic option for preventing PD-associated neuropathology.

New compound may halt drug-resistant lung cancer

The ability to make, test, and map the atomic structure of new anti-cancer agents has enabled a team of Dana-Farber Cancer Institute scientists to discover a compound capable of halting a common type of drug-resistant lung cancer.

Study: Protein channel aids nerve sensors in controlling blood pressure

University of Iowa researchers have shown that a protein channel helps nerve sensors in blood vessels keep blood pressure in check. Without the protein channel, known as ASIC2, the sensors are unable to send the brain the signals it needs to properly control blood pressure.

Motility mechanism of malaria pathogens explained

How do one-celled parasites move from the salivary gland of a mosquito through a person's skin into red blood cells? What molecular mechanisms form the basis for this very important movement of the protozoa?

Gene's role in immune system may suggest new treatments for childhood asthma

Pediatric researchers have identified a novel gene involved in childhood asthma, in one of the largest gene studies to date of the common respiratory disease. Because the gene, called DENND1B, affects cells and signaling molecules thought to be instrumental in the immune system overreaction that occurs in asthma, the discovery may have singled out an important target for new treatments.
