Cells often respond to external signals by altering their gene expression. The external signaling information is transduced and typically encoded in concentrations of relevant transcription factors. A recent study demonstrates that, by encoding this information in the frequency with which genes 'see' a transcription factor, the expression of hundreds of genes can be modulated in a linearly prop...

Our method is to compare estimates of a variety of characteristics for households sampled by Random Digit Dialing (RDD) methods and those contacted in person as part of an area probability sample. A large number of surveys are conducted using RDD samples, and are restr...
متن کاملDialing Down SUN1 for Laminopathies
Laminopathies, caused by mutations in A-type nuclear lamins, encompass a range of diseases, including forms of progeria and muscular dystrophy. In this issue, Chen et al. provide evidence that elevated expression of the nuclear inner membrane protein SUN1 drives pathology in multiple laminopathies.
