Like Burrs on Your Clothes, Molecule-size Capsules Can Deliver Drugs by Sticking to Targeted Cells

It is now possible to engineer tiny containers the size of a virus to deliver drugs and other materials with almost 100 percent efficiency to targeted cells in the bloodstream. According to a new Cornell study, the technique could one day be used to deliver vaccines, drugs or genetic material to treat cancer and blood and immunological disorders.

ADHD Genes Found; Known to Play Roles in Neurodevelopment

Pediatric researchers have identified hundreds of gene variations that occur more frequently in children with attention-deficit hyperactivity disorder than in children without ADHD. Many of those genes were already known to be important for learning, behavior, brain function and neurodevelopment. This is the first study to investigate the role of copy number variations in ADHD.

Scientists Out a Gene for Gout

Having partnered last year with an international team that surveyed the genomes of 12,000 individuals to find a genetic cause for gout, Johns Hopkins scientists now have shown that the malfunctioning gene they helped uncover can lead to high concentrations of blood urate that forms crystals in joint tissue, causing inflammation and pain "” the hallmark of this disease.

No Proof Found That Genetic Testing Helps Prevent Blood Clots

There is insufficient evidence to conclude that genetic testing for two gene mutations in adults with a history of blood clots helps to prevent deep-vein thrombosis.

Researchers Edit Genes in Human Stem Cells

Researchers at the Johns Hopkins School of Medicine have successfully edited the genome of human- induced pluripotent stem cells, making possible the future development of patient-specific stem cell therapies. Reporting this week in Cell Stem Cell, the team altered a gene responsible for causing the rare blood disease paroxysmal nocturnal hemoglobinuria, or PNH, establishing for the first time a useful system to learn more about the disease.

Scientists Find Faster, Cheaper Way to Identify Cancer-Causing Genes

Researchers at the University of Virginia Health System have found a new way to study how genes function in living organisms, and their approach could substantially cut the time and costs that drug makers spend in searching for potential targets for new cancer therapies.

Association for Molecular Pathology Comments to SACGHS

In pubic comments given today before the Secretary of Health and Human Services Advisory Committee on Genetics, Health and Society (SACGHS), the Association for Molecular Pathology (AMP) addressed three areas: Comparative Effectiveness Research (CER), evidence for coverage of genetic and genomic tests, and gene patents.

Father's Day Gift? Special Packaging for Genes in Sperm

It was long believed that conception doesn't involve a meeting of equals. The egg is a relatively large biological factory compared with the tiny sperm. However, a new study from Huntsman Cancer Institute at the University of Utah reveals that the father's sperm delivers much more complex genetic material than previously thought. The findings could lead to a test to help couples deal with infertility.

Jumping Genes Discovery "Challenges Current Assumptions"

Jumping genes do most of their jumping, not during the development of sperm and egg cells, but during the development of the embryo itself. The research challenges standard assumptions on the timing of when mobile DNA, so-called jumping genes, insert into the human genome.

Identify New Risk Factor Gene for Rheumatoid Arthritis

Feinstein Institute for Medical Research and a team of collaborators from across the country have identified a new risk factor gene for rheumatoid arthritis. The gene, dubbed REL, is a member of the NF-(kappa)B family. The NF-(kappa)B family seems to have a big hand in regulating the body's immune response.
