Children born through assisted reproduction at greater risk of obesity and type 2 diabetes related defects

More than three million children have been born as a result of assisted reproductive technologies since the birth of the first "test tube baby" in 1978. While the majority of these children are healthy and normal, as a group they are at greater risk of certain kinds of birth defects and being low birth weight, which is associated with obesity, hypertension and type 2 diabetes later in life.

Researchers develop new tool to understand how cancer grows

Researchers have a new tool to understand how cancers grow -- and with it a new opportunity to identify novel cancer drugs. They've been able to break apart human prostate tissue, extract the stem cells in that tissue, and alter those cells genetically so that they spur cancer.

Scientists develop new mathematical model to understand CML better

Doctors can now understand better chronic myeloid leukaemia (CML), including how it responds to therapy, thanks to a new mathematical model for the disease, developed by scientists in Portugal, Belgium and the United States. The work, to be published in the June edition of the journal Haematologica, also reveals that current therapies - which are not believed to cure CML - with the right protocol can actually get rid of the disease, and provides guidelines on how to do that.

Enzyme can allow nerve cells in brain to grow and form complex networks: Study

Brain researcher Hiroshi Kawabe has discovered the workings of a process that had been completely overlooked until now, and that allows nerve cells in the brain to grow and form complex networks. The study shows that an enzyme which usually controls the destruction of protein components has an unexpected function in nerve cells: it controls the structure of the cytoskeleton and thus ensures that nerve cells can form the tree-like extensions that are necessary for signal transmission in the brain.

Ways of stem cells division linked to development of cancer

Changes in the way that stem cells divide in the gut could lead to cancer, according to a new study funded by the Bobby Moore Fund for Cancer Research UK.

Amgen's Prolia Complete Response submission: FDA classifies and sets PDUFA date

Amgen Inc. today announced that the U.S. Food and Drug Administration (FDA) has evaluated the content of the Company's Complete Response submission for Prolia™ (denosumab) in the treatment of postmenopausal osteoporosis and classified it as a Class 2 resubmission. With the Class 2 designation, the FDA set a corresponding Prescription Drug User Fee Act (PDUFA) action date of July 25, 2010.

National poll examines public health response to anthrax attack

In a national poll aimed at helping with planning efforts for a public health response to a possible bioterrorism attack, researchers at the Harvard School of Public Health (HSPH) have found that, in response to a fictional scenario describing a significant anthrax attack in their city or town, most Americans (89%) will likely follow public health recommendations to obtain prophylactic antibiotics.

Polyphor discovers new class of antibiotics effective against multi-drug resistant Gram-negative bacteria

Today, Polyphor Ltd published the discovery of a new class of antibiotics with a novel mode of action (Science, VOL 327, ISSUE 5968). This proprietary new class of antibiotics is effective against multi-drug resistant Gram-negative bacteria, opening up new treatment options for serious and often life-threatening infections. The most advanced drug candidate in this new class, POL7080, selectively kills the dangerous bacteria Pseudomonas aeruginosa.

Kinesin protein motor shuttles cargo within cells and helps cells divide by rocking like a seesaw

Life's smallest motor, a protein that shuttles cargo within cells and helps cells divide, does so by rocking up and down like a seesaw, according to research conducted by scientists at the U.S. Department of Energy's Lawrence Berkeley National Laboratory and Brandeis University.

Traditional gauges of economic activity overstate standard of living, say researchers

Traditional gauges of economic activity severely overstate the standard of living as experienced on 'Main Street,' say University of Maryland researchers, who have worked with their state officials to apply a more accurate and greener index.

University of Missouri researchers visualize "terminals" inside proline degrading enzyme

If subway terminals didn't exist and people had to exit subway stations to switch subway lines, transit time would increase. People also may encounter distractions, such as grabbing a cup of coffee, instead of getting on the other line. Molecules also use "terminals" to save transit time during enzyme-catalyzed processes. Using advanced X-radiation techniques, University of Missouri researchers were able to visualize one of these terminals inside of an enzyme that degrades proline, which is an amino acid that has a central role in metabolism.

Major challenge facing today's toxicologists: Developing test systems to predict toxicity of compounds

Attagene Inc., a leader in developing innovative technologies for analyzing gene regulatory pathways, announced today the online publication of a paper in Chemical Research in Toxicology, a journal of the American Chemical Society, that highlights results of their collaborative work with the Environmental Protection Agency's National Center for Computational Toxicology (NCCT).

Cancer genomes: Distinguishing between 'driver' and 'passenger' mutations

A new study of mutations in cancer genomes shows how researchers can begin to distinguish the 'driver' mutations that push cells towards cancer from the 'passenger' mutations that are a by-product of cancer cell development. The study also shows that at least one in nine genes can be removed without killing human cells.

Most genetic abnormalities shared across multiple cancers

An international team of researchers has created a genome-scale map of 26 different cancers, revealing more than 100 genomic sites where DNA from tumors is either missing or abnormally duplicated compared to normal tissues. The study, the largest of its kind, finds that most of these genetic abnormalities are not unique to one form of cancer, but are shared across multiple cancers. The work appears in the February 18 issue of the journal Nature.

Simple molecular kit to reprogram any cell of the body into another

In an effort to sidestep the ethical dilemma involved in using human embryonic stem cells to treat diseases, scientists are developing non-controversial alternatives: In particular, they are looking for drug-like chemical compounds that can transform adult skin cells into the stem cells now obtained from human embryos. That's the topic of a fascinating article in Chemical & Engineering News (C&EN), ACS' weekly newsmagazine.

Emerging concepts from gene regulation studies in immune cells

The seventh meeting in the “Emergence and Convergence” series jointly organized by La Fondation IPSEN and Nature brings together today in San Antonio (Texas, USA) leading experts to discuss concepts emerging from gene regulation studies in immune cells that have led to insights into the initiation and maintenance of epigenetic chromatin marks necessary for proper differentiation and function of these cells in the immune system.
