Johns Hopkins to participate in 1000 Genomes Project

Researchers at the McKusick-Nathans Institute of Genetic Medicine (IGM) at Johns Hopkins will join other national and international scientists in the 1000 Genomes Project, an ambitious effort that will involve sequencing the genomes of numerous people from around the world to create the most detailed and medically useful picture to date of human genetic variation.

Genetic switches could lower cost of producing drugs, proteins

Bacteria have evolved complex mechanisms called quorum sensing systems that provide for cell-to-cell communication, an adaptation that allows them to wait until their population grows large enough before mounting an attack on a host or competing for nutrients.

Studies highlight MRSA evolution and resilience

Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) infections are caused primarily by a single strain USA300 of an evolving bacterium that has spread with "extraordinary transmissibility" throughout the United States during the past five years, according to a new study led by National Institutes of Health (NIH) scientists.

New knowledge base of gene-disease relationships

The 12 Million Euro 'GEN2PHEN' project, funded by the European Commission, aims to harness the web to capture and unify genetic information that fundamentally impacts on a person's health and disease processes.

Surgeons remove 11-pound desmoid tumor, transplant bowel back into patient

Surgeons at the University of Illinois Medical Center at Chicago removed an 11-pound desmoid tumor from the abdominal cavity of an Arkansas man and performed a transplant using a segment of his own small intestine rescued during surgery, preserving his ability to eat and digest food.

Discovery of multiple genes linked to systemic lupus erythematosus

A landmark genetic study has identified multiple genes linked to systemic lupus erythematosus (SLE), or lupus, a debilitating autoimmune disease that affects an estimated 1.4 million Americans.

Genome scan shows Polynesians and Micronesians have almost no genetic relation to Melanesians

The origins and current genetic relationships of Pacific Islanders have generated interest and controversy for many decades.

Genetic diversity of European Americans and disease gene mapping

Labels such as "European American", "white", or "Caucasian" are often viewed as representing a homogeneous category in gene mapping studies and census reports, but each of these labels actually groups together multiple populations, which have diverse origins due to the complex history of European immigration to the United States.
