Here we present the Transcription Factor Encyclopedia (TFe), a new web-based compendium of mini review articles on transcription factors (TFs) that is founded on the principles of open access and collaboration. Our consortium of over 100 researchers has collectively contributed over 130 mini review articles on pertinent human, mouse and rat TFs. Notable(More)
The heterogeneous nuclear ribonucleoprotein K protein is an RNA- and DNA-binding protein implicated in the regulation of multiple processes that comprise gene expression. We used chromatin immunoprecipitation (ChIP) assays to explore K protein interactions with serum-inducible, constitutively expressed and untranscribed gene loci in vivo. In the rat HTC-IR(More)
Definitive identification of promoters, their cis-regulatory motifs, and their trans-acting proteins requires experimental analysis. To define the HNRNPK promoter and its cognate DNA-protein interactions, we performed a comprehensive study combining experimental approaches, including luciferase reporter gene assays, chromatin immunoprecipitations (ChIP),(More)
BACKGROUND We analysed critically the potential usefulness of RNA- and DNA-based biomarkers in supporting conventional histological diagnostic tests for prostate carcinoma (PCa) detection. METHODS Microarray profiling of gene expression and DNA methylation was performed on 16 benign prostatic hyperplasia (BPH) and 32 cancerous and non-cancerous prostate(More)
Considering that postsynaptic densities (PSD) are a functionally active zone involved in excitatory synaptic transmission we evaluated the influence of global, postdecapitative cerebral ischemia of 15 min duration on characteristic protein constituents of PSD in rats. Ischemia induced changes in the assembly and function of calcium, calmodulin-dependent(More)
The heterogeneous nuclear ribonucleoprotein K (hnRNP K) protein is an RNA-binding protein involved in many processes that compose gene expression. K protein is upregulated in the malignant processes and has been shown to modulate the expression of genes involved in mitogenic responses and tumorigenesis. To explore the possibility that there are alternative(More)
The heterogeneous nuclear ribonucleoprotein K (hnRNP K), is a ubiquitously expressed protein that interacts with signal transducers, proteins that modulate gene expression and selective RNA and DNA motifs. K protein is modified in response to extracellular signals and directly regulates rates of transcription and translation. We used serum-treated(More)
Possession of a BRCA1/2 mutation increases risk of contralateral breast and ovarian cancer recurrence and may have an impact on health management decisions, such as imaging screening, preventive surgical interventions and systemic therapies. A hospital-based study was conducted to assess the frequency and spectrum of pathogenic germline BRCA1 and BRCA2(More)
Histone post-translational modifications (PTMs) play an important role in the regulation of the expression of genes, including those involved in cancer development and progression. However, our knowledge of PTM patterns in human tumours is limited. MS-based analyses were used to quantify global alterations of histone PTMs in colorectal cancer (CRC) samples.(More)
BACKGROUND Prostate cancer (PCa) and colorectal cancer (CRC) are the most commonly diagnosed cancers and cancer-related causes of death in Poland. To date, numerous single nucleotide polymorphisms (SNPs) associated with susceptibility to both cancer types have been identified, but their effect on disease risk may differ among populations. METHODS To(More)
