Expression of tyrosine kinases may limit effectiveness of agents against sarcomas

To better understand the signaling pathways active in sarcomas, researchers at Moffitt Cancer Center used state-of-the-art mass spectrometry-based proteomics to characterize a family of protein enzymes that act as "on" or "off" switches important in the biology of cancer. The tyrosine kinases they identified, the researchers said, could act as "drivers" for the growth and survival of sarcomas.

Majority of gene faults not shared across other biopsies from same tumour

Taking a sample from just one part of a tumour may not give a full picture of its 'genetic landscape', according to a landmark study published in the New England Journal of Medicine.

Cancer genomes in a common database and computation of disease drivers

The emerging field of "personalized" or "precision" medicine holds great promise in the fight against cancer. If scientists can identify the genetic changes that drive each patient's cancer cells, they can use that information to develop targeted treatments. But achieving this goal will require massive amounts of genomic and clinical data and a sophisticated infrastructure to manage and analyze the data.

Scientists are working out how sequencing the human genome can help treat disease

Though the human genome has been sequenced, scientists are still trying to figure out how the accomplishment can help people, for example, how it can be used to treat disease. As University of Massachusetts Amherst geneticist Jacob Mayfield notes, "It was easy to think of the human genome as the big prize, but what we realize now is, it's just a foot in the door."

FANCM gene plays key role in recombination of genetic information during inheritance

Scientists of KIT and the University of Birmingham have identified relevant new functions of a gene that plays a crucial role in Fanconi anemia, a life-threatening disease. The FANCM gene is known to be important for the stability of the genome.

Human iPS cells accrue genetic changes at about the same rate as replicating cells

A team of researchers from Johns Hopkins University and the National Human Genome Research Institute has evaluated the whole genomic sequence of stem cells derived from human bone marrow cells—so-called induced pluripotent stem (iPS) cells—and found that relatively few genetic changes occur during stem cell conversion by an improved method.

New class of drugs hold promise against aggressive forms of pancreatic cancer

Cancer Research UK-funded scientists have shown how a promising new class of drugs might be used to treat aggressive forms of pancreatic cancer, according to a study published in Nature.

Mirror-microRNAs control multiple aspects of brain function

Our genes control many aspects of who we are - from the colour of our hair to our vulnerability to certain diseases - but how are the genes, and consequently the proteins they make themselves controlled? Researchers have discovered a new group of molecules which control some of the fundamental processes behind memory function and may hold the key to developing new therapies for treating neurodegenerative diseases.

Breast-fed babies may have healthy gut microbial population

Early colonization of the gut by microbes in infants is critical for development of their intestinal tract and in immune development. A new study, published in BioMed Central's open access journal Genome Biology, shows that differences in bacterial colonization of formula-fed and breast-fed babies leads to changes in the infant's expression of genes involved in the immune system, and in defense against pathogens.

Fragile-X gene linked with disrupting de novo mutations in children with autism

A team led by scientists at Cold Spring Harbor Laboratory (CSHL) publishes research today indicating a striking association between genes found disrupted in children with autism and genes that are targets of FMRP, the protein generated by the gene FMR1, whose dysfunction causes Fragile-X syndrome.

Developing organisms can identify and repair head and facial abnormalities

Developmental biologists at Tufts University have identified a "self-correcting" mechanism by which developing organisms recognize and repair head and facial abnormalities. This is the first time that such a mechanism has been reported for the face and the first time that this kind of flexible, corrective process has been rigorously analyzed through mathematical modeling.

Kids who are abused or bullied may age faster

The study finds that violence-related stress in children affects telomeres - special DNA sequences found at the tips of chromosomes. Telomeres, which prevent DNA from unravelling, get shorter each time cells divide, which limits the number of times cells can divide. Shorter telomeres have been linked to poorer survival and chronic diseases. Previous research has shown that smoking, obesity, mental-health disorders and stress may accelerate the process of telomere loss. This suggests that telomere length may reflect a person's biological age as well as their chronological age.

Non-coding RNA gives off biological signals during viral infection

Once considered unimportant "junk DNA," scientists have learned that non-coding RNA (ncRNA) - RNA molecules that do not translate into proteins - play a crucial role in cellular function. Mutations in ncRNA are associated with a number of conditions, such as cancer, autism, and Alzheimer's disease.

Researchers create aqueous nanopore for use in high-speed genomic sequencing device

Researchers at Oak Ridge National Laboratory and Yale University have developed a new concept for use in a high-speed genomic sequencing device that may have the potential to substantially drive down costs.

Stress can shorten telomeres at a very young age

Children who have experienced violence might really be older than their years. The DNA of 10-year-olds who experienced violence in their young lives has been found to show wear and tear normally associated with aging, a Duke University study has found.

TopBP1 protein prevents early brain cells from DNA damage

St. Jude Children's Research Hospital scientists have rewritten the job description of the protein TopBP1 after demonstrating that it guards early brain cells from DNA damage. Such damage might foreshadow later problems, including cancer.

Results from Boehringer Ingelheim's afatinib Phase III lung cancer trial

Highly anticipated results from LUX-Lung 3, the pivotal Phase III lung cancer trial investigating Boehringer Ingelheim's front running oncology investigational compound, the ErbB Family Blocker afatinib, in patients with EGFR mutations, will be presented at the 48th Annual Meeting of the American Society of Clinical Oncology (ASCO) in Chicago from 1 - 5 June 2012.

Researchers uncover 22 new genes linked with autism, other neurodevelopmental disorders

When chromosomes replicate, sometimes there is an exchange of genetic material within a chromosome or between two or more chromosomes without a significant loss of genetic material. This exchange, known as a balanced chromosomal abnormality (BCA), can cause rearrangements in the genetic code.
