New technique to deliver gene therapy to soft-tissue tumors

Using new research and technology that shows bone marrow-derived mesenchymal stem cells (MSCs) will engraft at the site of a tumor and contribute to the growth of stromal fibroblasts (the healthy tissue surrounding a tumor)

How flexing of blood vessels during a heartbeat might contribute to heart disease

Duke biomedical engineers have received more than $2.2 million from the National Institutes of Health (NIH) to continue their explorations of how the complex moving and flexing of blood vessels during a heartbeat might contribute to heart disease.

Results look promising in Alzheimer’s gene therapy trial

Surgical placement of genetically modified tissue directly into the brains of patients with Alzheimer’s disease, an experimental approach to delaying brain cell loss associated with the disease, leads to increased metabolic activity in the brain, with cells apparently responding to the insertion of growth factor-producing grafts

Discovery shows how single genetic mutation can cause complex disorders

Bardet-Biedl syndrome (BBS), characterized by obesity, learning disabilities and eye and kidney problems, is caused by genetic mutations in the BBS family of genes. Now, researchers who've long studied the condition have discovered that genetic mutations in one of those genes, called BBS4, lead to cell death by disrupting the cells' internal "highway" system.

Genetically engineered bugs to fight cancer

GENETICALLY engineered bacteria could become the latest weapons against cancer, Cancer Research UK scientists suggest in a study published today 22nd April 2004.

Link between iron regulation and the immune system

Patients with chronic inflammatory disorders, including infections, inflammatory bowel disease, arthritis and cancer, commonly become anemic. The anemia can make them sicker, is sometimes severe enough to require a blood transfusion, and responds only partially to current treatments.

Genetic trick makes gene therapy vectors more versatile

A genetic trick used by viruses to replicate themselves has been adapted for laboratory use to build complex protein structures required by immune system cells, according to investigators at St. Jude Children’s Research Hospital.

Fluorescent molecule used to examine real time chemical reactions that result in smooth-muscle contraction

Smooth muscle, found in the walls of blood vessels and in internal organs such as lungs, stomach and the bladder, contracts as the end result of a series of chemical reactions. In a new study, UT Southwestern researchers report that one set of chemical reactions resulting in the contraction of the smooth-muscle cells is augmented by a second chemical pathway that kicks in when the first pathway is limited.

Protein Hydrogels Can be Genetically Engineered to Promote

Johns Hopkins University researchers have created a new class of artificial proteins that can assemble themselves into a gel and encourage the growth of selected cell types. This biomaterial, which can be tailored to send different biological signals to cells, is expected to help scientists who are developing new ways to repair injured or diseased body parts.

Novel vaccine technology to suppress the growth of certain tumors

MedImmune, Inc. and Cerus Corporation have announced preclinical results demonstrating the effectiveness of a novel therapeutic vaccine technology in suppressing the growth of certain tumors.

Growth factor protein succeeds in growing new coronary arteries

Three patients of the UC Heart & Vascular Center have grown new coronary artery branches to increase blood flow to the heart after receiving a new growth factor protein (FGF1) in November 2003. All three patients showed improved blood flow to the heart twelve weeks following the injection.

Drug Based on Brain Chemical Could End Narcolepsy and Insomnia

Researchers at UT Southwestern Medical Center at Dallas have discovered a potentially new avenue for treating human narcolepsy, and the work may also lead to more effective ways for insomniacs to boost their wakefulness during the daytime.
