abstract：:The Tor pathway mediates cell growth in response to nutrient availability, in part by inducing ribosomal protein (RP) gene expression via an unknown mechanism. Expression of RP genes coincides with recruitment of the Esa1 histone acetylase to RP gene promoters. We show that inhibition of Tor with rapamycin releases Es...
