Quercetin 13-22 interleukin 6 Homo sapiens 38-41 9367858-6 1997 In contrast, quercetin inhibited both HSF DNA-binding activity and HSF expression in HeLa cells. Quercetin 13-22 interleukin 6 Homo sapiens 67-70 9367858-7 1997 Our studies suggest that quercetin"s action is cell-type specific, and in breast cancer cells may involve regulation of HSF transcriptional activity, rather than regulation of its DNA-binding activity.

Quercetin 48-57 interleukin 6 Homo sapiens 102-106 16532021-8 2006 These results indicate that IL-1-stimulated IL-6 production from human mast cells is regulated by biochemical pathways distinct from IgE-induced degranulation and that quercetin can block both IL-6 secretion and two key signal transduction steps involved.

Quercetin 32-41 interleukin 6 Homo sapiens 154-157 11424089-4 2001 Our finding that a bioflavonoid quercetin (QCT), a well known inhibitor of hsp gene expression, significantly inhibited the transcriptional activation of HSF and HIF-1 strongly suggests that QCT-sensitive molecule(s) is involved in the transcriptional activation of HSF and HIF-1 by hypoxia. Quercetin 32-41 interleukin 6 Homo sapiens 266-269 10590836-3 1999 As the cellular heat shock response also involves the activation of heat shock transcription factor (HSF), we have, in the present study, examined the role of HSF in the stress potentiation of GR by use of a flavonoid compound, quercetin, recently shown to selectively inhibit the stress response in a variety of human and murine cell lines. Quercetin 228-237 interleukin 6 Homo sapiens 101-104 10590836-3 1999 As the cellular heat shock response also involves the activation of heat shock transcription factor (HSF), we have, in the present study, examined the role of HSF in the stress potentiation of GR by use of a flavonoid compound, quercetin, recently shown to selectively inhibit the stress response in a variety of human and murine cell lines. Quercetin 228-237 interleukin 6 Homo sapiens 159-162 10590836-6 1999 In L929 cells stably transfected with a CAT reporter plasmid under the control of the HSF-responsive hsp70 promoter (LHSECAT cells), pretreatment with quercetin was found to cause a dose- and time-dependent inactivation of HSF activity following heat shock, but only when added before the stress event. Quercetin 151-160 interleukin 6 Homo sapiens 86-89 10590836-6 1999 In L929 cells stably transfected with a CAT reporter plasmid under the control of the HSF-responsive hsp70 promoter (LHSECAT cells), pretreatment with quercetin was found to cause a dose- and time-dependent inactivation of HSF activity following heat shock, but only when added before the stress event. Quercetin 151-160 interleukin 6 Homo sapiens 223-226 10590836-9 1999 Thus, quercetin appears to be an effective and selective inhibitor of HSF stress-induced activation and its ability to prevent the stress potentiation of GR suggests either a direct or indirect involvement by stress-activated HSF in this process, or the existence of a regulatory step common to both the heat shock and HSPE responses.
