Discovery of cell fibrous structure may provide clues to diagnose and treat medical disorders

Researchers from the Johns Hopkins Engineering in Oncology Center have shown that in healthy cells, a bundled "cap" of thread-like fibers holds the cell's nucleus, its genetic storehouse, in its proper place.

Protein ERK oscillates between two major compartments in breast tissue cells

Time-lapsed video of individual breast tissue cells reveals a never-before-seen event in the life of a cell: a protein that cycles between two major compartments in the cell. The results give researchers a more complete view of the internal signals that cause breast tissue cells to grow, events that go awry in cancer and are targets of drug development.

Scientists provide the first comprehensive picture of minimal cell

What are the bare essentials of life, the indispensable ingredients required to produce a cell that can survive on its own? Can we describe the molecular anatomy of a cell, and understand how an entire organism functions as a system? These are just some of the questions that scientists in a partnership between the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, and the Centre de Regulacio Genòmica (CRG) in Barcelona, Spain, set out to address.

Wnt and EGFR signaling pathways interact to promote tumor cell invasion and metastasis

Two signaling pathways essential to normal human development - the Wnt/Wingless (Wnt) and epidermal growth factor receptor (EGFR) pathways - interact in ways that can promote tumor cell invasion and metastasis, researchers from The University of Texas M. D. Anderson Cancer Center report in the Nov. 25 issue of Molecular Cell.

Image of a water flea wins top prize in the 2009 Olympus BioScapes Digital Imaging Competition

A glowing, eerily beautiful image of a water flea with its radiant green "crown of thorns" took top prize in the 2009 Olympus BioScapes Digital Imaging Competition®, the world's foremost forum for showcasing microscope photos and movies of life science subjects. Dr. Jan Michels, a zoologist at the University of Albrecht, Kiel, Germany, took top honors for the image of a water flea, with its defensive "crown of thorns" to protect it against predators. The image reveals not only the exoskeleton, but also interior detail down to the nuclei within its cells, seen as tiny, glowing blue dots. This

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.

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.
