11-01-10 a jackson laboratory research team led by professor patsy nishina, ph.d., has identified a mutation（突变） in a gene that's essential for correct protein-processing in cells. defects in protein folding are associated with a variety of abnormalities...

10-12-24 the cell signaling pathway known as wnt, commonly activated in cancers, causes internal membranes（内膜） within a healthy cell to imprison（监禁，关押） an enzyme that is vital in degrading proteins, preventing the enzyme from doing its job and aff...

10-11-10 hormones, growth factors and several proteins ensure that development occurs in the right way, at the right time. the components that cause breast development in mammals, for example, were thought to be largely known. however, as a team of scientist...

10-09-10 amyloid（淀粉的） beta () proteins, widely thought to cause alzheimer's disease (ad), block the transport of vital cargoes（货物） inside brain cells. scientists at the gladstone institute of neurological disease (gind) have discovered that reducing...

10-08-26 functioning much like gears in a machine, cellular motor proteins are critical to dynamic（动态的，动力的） functions throughout the body, including muscle contraction, cell migration and cellular growth processes. now, neuroscientists from uc irvin...

10-08-10 researchers from carnegie mellon university's molecular biosensor and imaging center (mbic) are turning up the brightness on a group of fluorescent probes（荧光探针） called fluoromodules that are used to monitor biological activities of individual...

10-08-04 scientists hoping to understand how cells work may get a boost from a new technique to tag and image proteins within living mammalian（哺乳类） cells. the new technique, developed by a research team led by university of illinois at chicago assistant...

10-06-18 gene expression takes place in two stages: the transcription of dna to rna by an enzyme（酶） called rna polymerase（核糖核酸聚合酶） , , followed by the translation of this rna into proteins, whose behaviour affects the characteristics of each indi...

10-05-26 in a discovery that seems counterintuitive（违反直觉的） , a study appearing in the may 21st journal of biological chemistry has found that tendons（肌腱） in high-stress and strain areas, like the achilles tendon（跟腱） , actually repair themselve...

10-05-06 engineered artificial proteins that mimic the elastic properties（弹性，弹性性能） of muscles in living organisms are the subject of an article in nature magazine to be released may 6. our goal is to use these biomaterials in tissue engineering as a...
