TIAR represses c-Myc biosynthesis following ultraviolet light irradiation

ABSTRACT: RNA was isolated from material that had been subjected to immunoprecipitation (IP) from RKO cells that were either left untreated or irradiated with 20 J/m2 UVC and collected 1h later; IP assays were carried out using either an antibody recognizing RNA-binding protein TIAR, or using a control IgG1 antibody. RNA was reverse-transcribed in the presence of [alpha-33P]dCTP and the radiolabeled product used to hybridize human cDNA arrays. The experiment was repeated using three independent sample sets. The samples were numbered Tc-1, Tc-2, Tc-3, Tuv-1, Tuv-2, Tuv-3, IgG1c-1, IgG1c-2, IgG1c-3, IgG1uv-1, IgG1uv-2, and IgG1uv-3. ‘Tc’ denotes RNA from IP reactions using untreated cells and anti-TIAR antibody, ‘Tuv’ denotes RNA from IP reactions using UVC-treated cells and anti-TIAR antibody, ‘IgG1c’ denotes RNA from IP reactions using untreated cells and anti-IgG1 antibody, and ‘IgG1uv’ denotes RNA from IP reactions using UVC-treated cells and anti-IgG1 antibody. The numbers 1, 2 and 3 correspond to the three independent experimental datasets.
