11-02-24 Understanding the genetics of bipolar disorder(躁郁症) could lead to new treatments, but identifying specific genetic variations associated with this disorder has been challenging. A new study in Biological Psychiatry implicates a brain protein ca...
11-01-27 Professor Richard Watt and his chemistry students suspected that a common protein could potentially react with sunlight and harvest its energy similar to what chlorophyll(叶绿素) does during photosynthesis(光合作用) . The story of how they prove...
11-01-20 A team of scientists at The Scripps Research Institute and the University of Virginia has determined the structure of the protein package that delivers the genetic material of the human immunodeficiency virus (HIV) to human cells. The work is the cu...
11-01-10 Mayo Clinic researchers have shown that proteins on the surface of a cell twist a viral protein(病毒蛋白) into position, allowing the virus to start infection and cause disease, all in a movement as graceful as a ballroom dance. The findings appea...
10-12-29 Researchers at Washington University School of Medicine in St. Louis have learned why changes in a single gene, ROP18, contribute substantially(实质上,大体上) to dangerous forms of the parasite Toxoplasma gondii(弓形虫) . The answer has likely...
10-12-27 A study was carried out to examine the extent to which quercetin(槲皮黄酮) and trans-resveratrol (RSV) prevented inflammation or insulin resistance in primary cultures of human adipocytes(脂肪细胞) treated with tumor necrosis(坏死,坏疽) facto...
10-12-01 A new report in the December Cell Metabolism identifies a protein without which diets high in saturated fat(饱和脂肪) lead to a massive inflammatory(炎症的) response that can prove fatal. The studies in mice suggest that deficiencies in this pro...
10-11-23 Purdue University scientists have found the last undiscovered gene responsible for the production of the amino acid(氨基酸) phenylalanine, a discovery that could lead to processes to control the amino acid to boost plants' nutritional values and p...
10-11-07 United States and Japanese researchers have identified a key step in metabolic pathways(代谢途径) linked to diabetes and cancer. The study on activation of the protein complex TORC 2 was published online in the journal Current Biology Oct. 28. TOR...
10-11-03 A team of scientists from Japan and the University of California, San Diego School of Medicine have created a new mouse model that confirms that mutations of a protein called beta- synuclein(同型核蛋白) promote neurodegeneration(神经变性) . The...
