Scientists closer to unraveling the mechanisms of gene regulation

A team led by Penn State's Ross Hardison, T. Ming Chu Professor of Biochemistry and Molecular Biology, has taken a large step toward unraveling how regulatory proteins control the production of gene products during development and growth.

New biomarkers can predict patients' response to certain drugs

Recent advances in cancer therapeutics have led to the discovery of biomarkers that can predict patient response to certain drugs. Screening for mutations in the epidermal growth factor receptor (EGRF) prior to non-small cell lung cancer treatment, for example, has been shown to indentify patients who are likely to respond to treatment with erlontinib. This maximizes the drug's impact, and spares patients who are not likely to benefit from being subjected to potentially debilitating side effects.

Gene that tells embryonic stem cells when to stop producing neurons identified

Researchers from North Carolina State University have identified a gene that tells embryonic stem cells in the brain when to stop producing nerve cells called neurons. The research is a significant advance in understanding the development of the nervous system, which is essential to addressing conditions such as Parkinson's disease, Alzheimer's disease and other neurological disorders.

Phase 2 clinical trial to test gene therapy treatment for Alzheimer's disease

Mount Sinai School of Medicine is one of 12 sites nationwide participating in the first Phase 2 clinical trial to test gene therapy treatment for Alzheimer's disease. The study is the first multicenter neurosurgical intervention in Alzheimer's research in the U.S.

New insights into cells' reaction to DNA damage

Cancer researchers of the Max Delbr-ck Center for Molecular Medicine (MDC) Berlin-Buch have gained new insights into how cells react to DNA damage. Dr. Michael Stilmann, Dr. Michael Hinz and Professor Claus Scheidereit have shown that the protein PARP-1, which detects DNA damage within seconds, activates the transcription factor NF-kappaB, a well-known regulator of gene expression.

Cytoskeleton plays a critical role to bring chromosome pairs together: Study

Meiosis - the pairing and recombination of chromosomes, followed by segregation of half to each egg or sperm cell - is a major crossroads in all organisms reproducing sexually. Yet, how the cell precisely choreographs these chromosomal interactions is a long-standing question.

Stapled Peptides directly inhibit the Notch transcription factor complex

Aileron Therapeutics, a biopharmaceutical company leading the development of a new class of drugs called Stapled Peptides, announced today that its collaborators, James E. Bradner, MD of the Dana-Farber Cancer Institute and the Broad Institute of Harvard and MIT, and Gregory L. Verdine, PhD, Professor of Chemistry at Harvard University, published research in Nature entitled, “Direct Inhibition of the Notch Transcription Factor Complex.”

Stapled Peptides can inhibit key intracellular biological targets, says new research

Aileron Therapeutics, a biopharmaceutical company leading the development of a new class of drugs called Stapled Peptides, announced today that its collaborators, James E. Bradner, MD of the Dana-Farber Cancer Institute and the Broad Institute of Harvard and MIT, and Gregory L. Verdine, PhD, Professor of Chemistry at Harvard University, published research in Nature entitled, "Direct Inhibition of the Notch Transcription Factor Complex." Results presented in the paper showed that Stapled Peptides can potently and directly inhibit the transcription factor Notch, an oncogene implicated in cancer cell proliferation and survival.

HFSP grant to develop molecular probes to study "cellular GPS" system

An international group of researchers from Carnegie Mellon University, Goettingen Medical School in Germany and the University of Cambridge in the United Kingdom have received a Human Frontiers Science Program (HFSP) grant to develop molecular probes that will help researchers better understand the "cellular GPS" system that guides neurons to create a properly wired nervous system.

Experts gather to outline the latest creative applications of DNA barcoding

The scientific ability to quickly and accurately identify species through DNA "barcoding" is being embraced and applied by a growing legion of global authorities - from medical and agricultural researchers to police and customs authorities to palaeontologists and others.

Researchers find compound that reverses type 1 myotonic dystrophy

A compound already used to treat pneumonia could become a new therapy for an inherited muscular wasting disease, according to researchers at the University of Oregon and the University of Rochester School of Medicine and Dentistry in New York.

Gene therapy saves two children with adrenoleukodystrophy

The ELA association and Zinedine Zidane, its emblematic ambassador, are proud to announce a world premiere: the results regaring the gene therapy in adrenoleukodystrophy conducted in France have just been published in the prestigious journal Science. Two children have been treated and their diseases have been halted. The children are doing well, which is unexpected for a disease destroying the brain in a few months. This discovery opens up treatment perspectives for numerous widespread diseases.

New therapeutic approach targets cancer cells, not normal cells

The ultimate goal in cancer research, a treatment that kills cancer cells whilst leaving healthy cells untouched, is brought nearer by the success of a new therapeutic approach. The potential therapy, published in BioMed Central's open access journal Breast Cancer Research, targets proliferation of cancer, but not normal, cells.

Tinnitus patients need more support and advice on healthcare options

As many as one in seven people will experience tinnitus, or ringing in their ears, at some time of their life, but not enough is being done to support patients who experience this distressing condition, according to an extensive research review in the November issue of the Journal of Clinical Nursing.

Stereotactic radiosurgery effective in eliminating Parkinson's disease tremors

Stereotactic radiosurgery (SRS) offers a less invasive way to eliminate tremors caused by Parkinson's disease and essential tremor than deep brain stimulation (DBS) and radiofrequency (RF) treatments, and is as effective, according to a long-term study presented November 2, 2009, at the 51st Annual Meeting of the American Society for Radiation Oncology (ASTRO).

Deep brain stimulation can help patients with severe forms of depression

In deep brain stimulation, doctors specifically target the impaired function of certain areas of the brain with an electric brain pacemaker. For the purpose of this study, they implanted electrodes in what is known as the nucleus accumbens. That is an important part of the 'reward system' which ensures that we remember good experiences and puts us in a state of pleasant anticipation.

Stress-evoked changes can precipitate low mood and re-ignite drug-seeking behaviors

Stress-evoked changes in circuits that regulate serotonin in certain parts of the brain can precipitate a low mood and a relapse in cocaine-seeking, based on mouse studies published online this week in the Proceedings of the National Academy of Sciences.

Brain cell transplants help replace degenerated neurons, finds Swiss research team

A Swiss research team has found that using an animal's own brain cells (autologous transplant) to replace degenerated neurons in select brain areas of donor primates with simulated but asymptomatic Parkinson's disease and previously in a motor cortex lesion model, provides a degree of brain protection and may be useful in repairing brain lesions and restoring function.
