HDAC Inhibitors and Heat Shock Proteins (Hsps)
Epigenetic alterations, including DNA acetylation, hypermethylation and hypomethylation, and the associated transcriptional changes of the affected genes are central to the evolution and progression of various human cancers, including pancreatic cancer. Cancer-associated epigenetic alterations are attractive therapeutic targets because such epigenetic alterations, unlike genetic changes, are po...

متن کاملImplications of heat shock/stress proteins for medicine and disease.
Heat shock/stress proteins (HSPs) are crucial for maintenance of cellular homeostasis during normal cell growth and for survival during and after various cellular stresses. The HSP70 family functions as molecular chaperones and reduces stress-induced denaturation and aggregation of intracellular proteins. In addition to the chaperoning activities, HSP70 has been suggested to exert its protectiv...
متن کاملThe function of heat-shock proteins in stress tolerance: degradation and reactivation of damaged proteins.
We earlier demonstrated that hsp68 is deficiently induced upon stress in the glucocorticoid-resistant, dedifferentiated Reuber rat hepatoma clone 2 cells, but is strongly activated in the differentiated, glucocorticoid-sensitive Faza 967 cells from which clone 2 was derived. We used the two cell types to address the questions whether hsp68 is specifically involved in the development of thermoto...
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...
