Global RNA stability profiling in HEK293T cells under EGF treatment using TimeLapse-seq


ABSTRACT: We discovered through LC-MS/MS followed by biochemical assays and immunofluorescence that human microprotein NoBody/NBDY can be phosphorylated during EGF signaling transduction, and that this single post-translational modification of the smallest decapping complex component known to date is necessary to the observed disappearance of P-bodies under EGF treatment. RNA stability measurement of a known hDcp2 substrate, RRP41, showed decreased RNA life-time under EGF treatment. We hence wish to investigate the effect of this phospho-NBDY mediated P-body disassembly on global RNA turnover. Here we present a global profile of RNA stability in human HEK293 cells under EGF treatment via TimeLapse-seq. By comparing this dataset to our previous and current work done in DCP2 KO and in NBDY KO cells, respectively, we demonstrate that P-body dissociation observed during EGF signaling does not cause RNA stability change globally except for a few known EGF regulated transcripts.
