In response to various stress stimuli, heat shock genes are induced to express heat shock proteins (Hsps). Previous studies have revealed that expression of heat shock genes is regulated both at transcriptional and posttranscriptional level, and the rapid transcriptional induction of heat shock genes involves activation of the specific transcription factor, heat shock factor 1 (HSF1). Furthermo...
BACKGROUND Heat shock protein 70 (HSP70) is present in all organisms studied so far, and is a major immunogen in infections caused by pathogens including Leishmania spp. OBJECTIVE The aim of this study was to clone and express HSP70 from L. infantum strain MCAN/IR/96/LON-49 and evaluate antibody response against HSP70 in visceral leishmaniasis (VL). METHODS The L. infantum HSP70 gene segmen...
Compound A possesses glucocorticoid receptor (GR)-dependent anti-inflammatory properties. Just like classical GR ligands, Compound A can repress NF-κB-mediated gene expression. However, the monomeric Compound A-activated GR is unable to trigger glucocorticoid response element-regulated gene expression. The heat shock response potently activates heat shock factor 1 (HSF1), upregulates Hsp70, a k...
Heat shock proteins (HSPs) are molecular chaperones that bind to other proteins to shepherd them across membranes and direct them to specific locations within a cell. Several injurious stimuli can induce Hsp70 expression, including ischemia. This study aimed to investigate the pattern of expression of protein (immunohistochemistry) and gene (real-time PCR) Hsp70 in experimental focal cerebral i...
Differentiation of neural progenitor cells of neuroblastoma, pheochromocytoma, and surrogate stem cell lineages from a state resembling stem cells to a state resembling neurons is accompanied by a marked attenuation in induction of the heat shock protein 70 promoter driven-luciferase reporter gene, and induction of the reporter gene in primary embryonic neurons from hippocampus, cortex, and spi...
background: oct4b1, a novel variant of oct4, is expressed in cancer cell lines and tissues. based on our previous reports, oct4b1 appears to have a crucial role in regulating apoptosis as well as stress response [heat shock proteins (hsps)] pathways. the aim of the present study was to determine the effects of oct4b1 silencing on the expression of high molecular weight hsps in three different h...
Background Our understanding of those underlying mechanisms that contribute to metastatic progression in melanoma remains limited. While uncommon, hyperprogression response immunotherapy is likely be an extreme form acquired resistance. Therefore, studies define the these processes are expected provide insight into discovery novel therapeutic targets and predictive biomarkers. We previously dem...
Induced expression of the HSP70 gene in 3T3 and SV-3T3 cells was monitored by measurements of the synthesis of HSP70 and of the cellular contents of both HSP70 and its mRNA. The presence of betaine (N-trimethylglycine) at concentrations of 2.5-25 mM decreased the induction of HSP70 gene expression caused by incubation of 3T3 and SV-3T3 cells in hypertonic (0.5 osM) medium. This effect was accom...
Light at night and light interference (LI) disrupt the natural light:dark cycle, causing alterations at physiological and molecular levels, partly by suppressing melatonin (MLT) secretion at night. Heat shock proteins (HSPs) can be activated in response to environmental changes. We assessed changes in gene expression and protein level of HSP70 in brain and hepatic tissues of golden spiny mice (...
