Using cultured pear (Pyrus communis cv Bartlett) cells, heat tolerance induced by heat shock was compared to that developed during growth at high temperature. After growth at 22 degrees C, cells exposed to 38 degrees C for 20 minutes (heat shock) showed maximum increased tolerance within 6 hours. Cells grown at 30 degrees C developed maximum heat tolerance after 5 to 6 days; this maximum was we...
Extracellular stresses induce heat shock response and render cells resistant to lethal stresses. Heat shock response involves induction of heat shock proteins (Hsps). Recently the roles of Hsps in neurodegenerative diseases and cancer are attracting increasing attention and have accelerated the study of heat shock response mechanism. This review focuses on the stress sensing steps, molecules in...

The induction of tetraploidy by means of cold, heat and multiple heat shock treatments was investigated on male fish from a growth-enhanced transgenic tilapia C118 line, crossed with wild type females. After the development a new multiple heat shock protocol (two heat treatments at 41oC in 60 and 80 min. after fertilization for 5 min. per each), chromosome and X-gal in situ staining assays demo...
Heat shock protein 90 (hsp90) accounts for 1-2% of the total proteins in normal cells and it functions as a dimer. Hsp90 behaves as a molecular chaperone that folds, assembles, and stabilizes client proteins. We have developed a novel hsp90 inhibitor, and herein we describe the synthesis and biological activity of the dimerized variant of this inhibitor. Tethering a monomer inhibitor together p...
Previous work has implicated heat shock transcription factor 1 (HSF1) as the primary transcription factor responsible for the transcriptional response to heat stress in mammalian cells. We characterized the heat shock response of mammalian cells by measuring changes in transcript levels and assaying binding of HSF1 to promoter regions for candidate heat shock genes chosen by a combination of ge...
The public reporting burden for this collection of information is estimated to average 1 hour per response, including the time for reviewing instructions, searching existing data sources, gathenng and maintaining the data needed, and completing and reviewing the collection of information. Send comments regarding this burden estimate or any other aspect of this collection of information, includi...
Mutations in HSPB1 and HSPB8, members of the small heat shock protein family, have recently been shown to cause some distal motor neuropathies. Their function in motor neurones is now under scrutiny.
