Insights into Acute Promyelocytic Leukemia

...solutely essential for APL development in PML/RARA transgenic mice. Pharmacological activation of RXR relieved PML/RARA-induced transcriptional repression and triggered APL differentiation only when RXR was in a complex with PML/RARA. In addition, PML/RARA promoted posttranslational modifications of RXR, inc...

Antibody-based Therapies Effective at Controlling Malaria

...s can be determined using rodent malaria parasites transgenic for P. falciparum antigens in mice and humans. An in vivo mouse model has significant advantage over the use of new world primates, the only other model for human malaria, which are labor-intensive and difficult to reproduce. These novel human reag...

Scientists Develop Method to Track Immune System Enzyme in Live Animals

...his issue, Dr. Casellas and his colleagues created transgenic mice that had a green fluorescent protein derived from jellyfish fused to the AID enzyme. In these transgenic animals, B cells express the tagged enzyme during the immune response. In a second mouse strain, C...

Pediatric Cancer Stem Cell Identified

...a strain of genetically engineered zebrafish. Some transgenic zebrafish developed visible tumors by 10 days of age. Through their model, Dr. Zon and colleagues were able to identify both an ERMS tumor-cell-of-origin and a novel genetic signature that underlies ERMS progression in zebrafish and human patients...

Research may Yield Improved Treatment for Diseased Lungs

...on in molecular biology will enable Chesler to use transgenic mice to explore the physical role of collagen-mediated large-artery stiffening in pulmonary arterial hypertension. She will induce large-artery stiffness in the mice in a process that mimics scleroderma, a disease in which the body produces too much ...

Researchers Discovers DNA Repair as Key to Huntington's Disease

... Director Elias Zerhouni, M.D. In their study of transgenic mice that carried the human Huntington’s gene, the researchers noted that the repeated tracts of replacement repair segments seem stable until the animals reach about 4 months of age. After that point -- which represents middle age for a mouse -- the...

The Story Behind the Shape of the Heart

...man, Deborah Yelon, and colleagues found, by using transgenic zebrafish in which they can watch individual cardiac cells, that cells change size and shape, enlarging and elongating to form the bulges in the heart tube and eventually the chambers. Since the heart is beating as it develops, they asked whether car...

According to Frost and Sullivan, the European omega-3 market was worth around €160m (￡108m) in 2004, and is expected to grow at rates of ...

Cancer Research May Help Biofuels

...oreign genes into a plant, which creates so-called transgenic plants. Instead, it removes genes from a species, modifies them and then reinserts them. Founded in 1999, the company has primarily worked with agribusiness concerns like Monsanto but in the past few years has begun to more closely examine using it...

...ase." LaFerla and other colleagues developed the transgenic mice used in this study. These mice, bred to develop the brain lesions associated with Alzheimer's, now are used by scientists worldwide to study the disease. Alzheimer's is a progressive neurodegenerative disorder that affects more than 4.5 millio...

'Hen Factories' To Synthesize Cancer Drugs

Some of these genetically- engineered transgenic hens produced eggs whose whites contained proteins like the monoclonal antibody, m1r24, used in the treatment of melanoma, while other hens were engineered to produce a type of human interferon that impairs viral replication. These proteins may t...
