Nanomedicine Center for Nucleoprotein Machines receives $16.1 million NIH award

The Georgia Tech-led Nanomedicine Center for Nucleoprotein Machines has received an award of $16.1 million for five years as part of its renewal by the National Institutes of Health (NIH). The eight-institution research team plans to pursue development of a clinically viable gene correction technology for single-gene disorders and demonstrate the technology's efficacy with sickle cell disease.

First genetically engineered rat derived from rat ES cells developed with StemCells' technology

StemCells, Inc. announced today that its technology was recently used by independent researchers to achieve the first genetically engineered rat derived from rat embryonic stem (ES) cells. This breakthrough, published this month in the international peer-reviewed journal Nature, opens the door to the types of genetic manipulations previously only possible in mice, and paves the way for modeling a broader range of human diseases with the rat.

Scientists identify possible therapeutic strategy for reducing leukemia risk from chemotherapy

A UCSF-led team has discovered at least one key reason why blood stem cells are susceptible to developing the genetic mutations that can lead to adult leukemia. Their finding also may explain, they say, why some other age-related hematological disorders develop.The study, reported in "Cell Stem Cell" and reviewed in Cell Stem Cell and Cell, opens a new frontier for studying the molecular underpinnings of adult leukemia.

RPA70 associated with SUMO-specific protease facilitates DNA repair: Research

A team of investigators led by a physician-scientist at The University of Texas MD Anderson Cancer Center has shown for the first time that the small protein SUMO can team up with the replication protein A (RPA) complex to facilitate DNA repair. The study is published in the Aug. 13 edition of the journal Molecular Cell.

Researchers discover enzyme crucial for DNA repair

Researchers have discovered an enzyme crucial to a type of DNA repair that also causes resistance to a class of cancer drugs most commonly used against ovarian cancer.Scientists from The University of Texas MD Anderson Cancer Center and the Life Sciences Institute of Zhejiang University in China report the discovery of the enzyme and its role in repairing DNA damage called cross-linking in the Science Express advance online publication of Science.

Retinitis Pigmentosa: Embryonic stem cells for replacement of diseased retinal cells and restoration of sight

An international research team led by Columbia University Medical Center successfully used mouse embryonic stem cells to replace diseased retinal cells and restore sight in a mouse model of retinitis pigmentosa. This strategy could potentially become a new treatment for retinitis pigmentosa, a leading cause of blindness that affects approximately one in 3,000 to 4,000 people, or 1.5 million people worldwide.

Gene modification of human embryonic stem cells may yield potential treatments for genetic diseases

Biologists have developed an efficient way to genetically modify human embryonic stem cells. Their approach, which uses bacterial artificial chromosomes to swap in defective copies of genes, will make possible the rapid development of stem cell lines that can both serve as models for human genetic diseases and as testbeds on which to screen potential treatments, they say.

AACR-NCI-EORTC conference highlights major expansion in cancer drug pipeline

To highlight results of more recent research, the AACR-NCI-EORTC Molecular Targets and Cancer Therapeutics International Conference will host a press briefing on "Drugs in the Pipeline." Sara A. Courtneidge, Ph.D., D.Sc., professor and director of the Tumor Microenvironment Program, and director of academic affairs at the Burnham Institute for Medical Research, will moderate this press briefing.
