Odors Can Alter Gene Expression In An Olfactory Neuron

In a study of how sensory neurons in the microscopic worm C. elegans process smell, researchers have discovered the first evidence that a chemical in the environment changes gene expression within a sensory organ in its own specific way. The investigators also report that in contrast to previous studies showing that Pumilio proteins suppress gene expression, the proteins are activators of expression in the worm's olfactory sensory cell.
