Translational reprogramming in cellular stress response.
Cell survival in changing environments requires appropriate regulation of gene expression, including translational control. Multiple stress signaling pathways converge on several key translation factors, such as eIF4F and eIF2, and rapidly modulate messenger RNA (mRNA) translation at both the initiation and the elongation stages. Repression of global protein synthesis is often accompanied with ...
متن کاملSwitching regulatory models of cellular stress response
MOTIVATION Stress response in cells is often mediated by quick activation of transcription factors (TFs). Given the difficulty in experimentally assaying TF activities, several statistical approaches have been proposed to infer them from microarray time courses. However, these approaches often rely on prior assumptions which rule out the rapid responses observed during stress response. RESULT...
متن کاملHeat shock proteins and the cellular response to osmotic stress.
In antidiuresis, the intrarenal distribution of HSP25/27, alphaB-crystallin, HSP72, OSP94 and HSP110 corresponds to the osmotic gradient between cortex and papilla: low amounts in the cortex and high values in the inner medulla and papilla. In addition, medullary HSP72 levels change appropriately with the diuretic state. Studies on MDCK cells suggest that, in the renal medulla in vivo, stressor...
متن کاملCellular response of Shewanella oneidensis to strontium stress.
The physiology and transcriptome dynamics of the metal ion-reducing bacterium Shewanella oneidensis strain MR-1 in response to nonradioactive strontium (Sr) exposure were investigated. Studies indicated that MR-1 was able to grow aerobically in complex medium in the presence of 180 mM SrCl2 but showed severe growth inhibition at levels above that concentration. Temporal gene expression profiles...
متن کاملPINCH in the Cellular Stress Response to Tau-Hyperphosphorylation
Particularly interesting new cysteine- histidine- rich protein (PINCH) is an adaptor protein that our data have shown is required for neurite extension under stressful conditions. Our previous studies also report that PINCH is recalled by neurons showing decreased levels of synaptodendritic signaling proteins such as MAP2 or synaptophysin in the brains of human immunodeficiency virus (HIV) pati...
