Diverse genetic abnormalities lead to NF-κB activation in multiple myeloma

...cular mechanisms that underlie aberrant NF-κB activity in MM tumor cells and underscores the relevance of the NF-κB signaling pathway as a target for MM therapy. MM is a cancer of the plasma cell, a blood cell that produces antibodies to help the body fight off infections. Previous research implic...

Interaction of just 2 genes governs coloration patterns in mice

...hanging the protein's sequence, also reducing Mc1r activity and yielding lighter pigmentation. Both genes affect the type and amount of melanin in individual hairs. When both genes are turned on, the mouse is dark in color. A mutation that changes either gene leads to a somewhat blonder mouse, but it is the...

Green tea boosts production of detox enzymes, rendering cancerous chemicals harmless

In 2001, the Peruvian government placed 31% of the managed forests into permanent resource production. By 2005,...

Genetic variation helps to understand predisposition to schizophrenia

...oter for the Neuregulin 1 gene and showed that the activity of that gene is altered by a single genetic variation in this promoter, Law says. These results will probably help us understand how DNA variations affect the function of this gene and lead to symptoms of schizophrenia. The researchers are now pl...

Antioxidant overload may underlie a heritable human disease

...ted a heightened stress response, including higher activity of heat shock proteins that have been documented in human heart failure, Benjamin explained. Such stress responses yield reactive oxygen species, triggering antioxidative pathways to kick in. In the diseased animals, however, that pathwayin which oxi...

Link between sunspots, rain helps predict disease in east Africa

...Africa over the past century preceded peak sunspot activity by about one year. "The hope is that people on the ground will use this research to predict heavy rainfall events," Stager said. "Those events lead to erosion, flooding and disease. With the help of these findings, we can now say when especially ra...
