Researchers learn how signaling molecule orchestrates breast cancer's spread

A study led by researchers at Memorial Sloan-Kettering Cancer Center (MSKCC) has uncovered how breast tumors use a particular type of molecule to promote metastasis -- the spread of cancer cells. Metastasis is the cause of approximately 90 percent of all cancer-related deaths.

New web portal, the PSI Structural Genomics Knowledgebase to advance protein studies

The Protein Structure Initiative (PSI), an effort supported by the National Institutes of Health (NIH), has launched an online resource that will enable scientists from across biomedical disciplines to easily access a wealth of information about proteins and to speed discovery about these molecules.

Answer to troublesome question of why some genetic assoc. studies have failed replication attempts

A team of researchers from Harvard School of Public Health (HSPH), Brigham and Women's Hospital (BWH), and elsewhere have described a possible reason why some studies have been unable to replicate associations between genes and traits -- namely that the strength of a gene/trait association might vary with age and that current study designs typically fail to take that into account.
