Expression dynamics in mammalian cells responding to protein misfolding stress. Homo sapiens

We have employed whole genome microarray expression profiling to track the transcriptome expression change under DTT induced protein misfolding stress. The relative importance of gene expression regulation at the mRNA versus the protein-level is a matter of ongoing debate. We present an in-depth analysis of a cervical cancer cell line responding to protein misfolding stress induced by dithiothreitol treatment, quantifying the dynamics of mRNA and protein concentrations for >3,500 genes over a time-course 30 hours. While the early phase of the experiment (
