Key factors contributing to early stages of atherosclerosis and plaque development include the pro-inflammatory cytokines Interferon (IFN)α, IFNγ and Interleukin (IL)-6 and Toll-like receptor 4 (TLR4) stimuli. Together, they trigger activation of Signal Transducer and Activator of Transcription (STAT) and Interferon Regulatory Factor (IRF) families. In(More)
OBJECTIVE We have applied fluorimetric method to monitor aldehyde dehydrogenase (ALDH*) activity in human saliva samples to study inactivation, reactivation and inhibition of the enzyme. DESIGN Saliva samples were collected to buffer stock solution, containing various thiols, and assayed in the presence of the fluorogenic substrate(More)
Signal transducers and activators of transcription (STATs) comprise a family of transcription factors that are structurally related and which participate in signaling pathways activated by cytokines, growth factors and pathogens. Activation of STAT proteins is mediated by the highly conserved Src homology 2 (SH2) domain, which interacts with phosphotyrosine(More)
Higher plants evolved mechanisms of uptake, distribution and accumulation of trace metals essential for the proper functioning of the organism (e.g., copper, zinc). Non-essential metals (e.g., cadmium, arsenic, lead) can also enter plant cells using the routes dedicated to the essential ones, because of the shared similar chemical and physical properties.(More)
VHL inactivation is the most established molecular characteristic of clear cell renal cell carcinoma (ccRCC), with only a few additional genes implicated in development of this kidney tumor. In recently published ccRCC gene expression meta-analysis study we identified a number of deregulated genes with limited information available concerning their(More)
Signal transducers and activators of transcription (STATs) are a family of proteins activated by different stimulating factors, including interferons, interleukins, growth factors and oncoproteins. Their role in many diseases has been proven, so there is a strong demand to find specific strategies for STAT inhibition. Our searches for specific(More)
Signal transducers and activators of transcription (STATs) facilitate action of cytokines, growth factors and pathogens. STAT activation is mediated by a highly conserved SH2 domain, which interacts with phosphotyrosine motifs for specific STAT-receptor contacts and STAT dimerization. The active dimers induce gene transcription in the nucleus by binding to(More)
STATs promote fundamental cellular processes, marking them as convergence points of many oncogenic and inflammatory pathways. Therefore, aberrant activation of STAT signaling is implicated in a plethora of human diseases, like cancer, inflammation and auto-immunity. Identification of STAT-specific inhibitors is the topic of great practical importance, and(More)
