Opis ogólny
A cell-permeable 2,6-diaminopyridine compound that interacts with HSF1 (heat shock factor 1) in a reversible manner and prevents HSF1 from recruiting p-TEFb (positive transcription elongation factor b) to the hsp70 promoter site (IC50 ≤3 µM in HCT-116 ChIP assays), a critical step for the p-TEFb CDK9 subunit-catalyzed pol II CTD (RNA polymerase II c-terminal domain) Ser-2 phosphorylation and transcription activation upon heat shock induction (IC50<1, <3, <5, and <10 µM, respectively, against reporter, HSP47, HSP27, and HSP70 transcription in HCT-116 cultures). Reported to exhibit antiproliferation activity against several cancer cultures in vitro (IC50 ranges from 3 to 8 µM) and effectively suppress HCT-116-derived tumor growth in mice in vivo (by 47.4% on day 31; single i.p. dosage of 50 mg/kg on day 13 after cancer implantation). Does not affect TNF-α-induced NF-κB activity in HeLa or heat shock-induced HSF1 ser230 phosphorylation and promoter association in HCT-116 even at concentrations as high as 10 µM.

Heat shock factor 1 (HSF1) is the master switch for heat shock protein (HSP) expression in eukaryotes. A synthetic chemical library was screened to identify inhibitors of HSF1 using a luciferase reporter under the control of a heat shock element.

Modulated electro-hyperthermia (mEHT) is a complementary antitumor therapy applying capacitive radiofrequency at 13.56 MHz. Here we tested the efficiency of mEHT treatment in a BALB/c mouse isograft model using the firefly luciferase-transfected triple-negative breast cancer cell line, 4T1. Tumors inoculated

Master transcription factors control the transcriptional program and are essential to maintain cellular functions. Among them, steroid nuclear receptors, such as the estrogen receptor α (ERα), are central to the etiology of hormone-dependent cancers which are accordingly treated with corresponding

Brown adipose tissue (BAT) thermogenic activity is tightly regulated by cellular redox status, but the underlying molecular mechanisms are incompletely understood. Protein S-nitrosylation, the nitric-oxide-mediated cysteine thiol protein modification, plays important roles in cellular redox regulation. Here we show that

Macrophages generate mitochondrial reactive oxygen species and mitochondrial reactive electrophilic species as antimicrobials during Toll-like receptor (TLR)-dependent inflammatory responses. Whether mitochondrial stress caused by these molecules impacts macrophage function is unknown. Here, we demonstrate that both pharmacologically driven and lipopolysaccharide
