Investigating transcription factor synergism in humans
Proteins are the core and the engine of every process in cells thus the study of mechanisms that drive the regulation of protein expression, is essential. Transcription factors play a central role in this extremely complex task and they synergically co-operate in order to provide a fine tuning of protein expressions. In the present study, we designed a mathematically well-founded procedure to i...
متن کاملPredicting transcription factor synergism.
Transcriptional regulation is mediated by a battery of transcription factor (TF) proteins, that form complexes involving protein-protein and protein-DNA interactions. Individual TFs bind to their cognate cis-elements or transcription factor-binding sites (TFBS). TFBS are organized on the DNA proximal to the gene in groups confined to a few hundred base pair regions. These groups are referred to...
متن کاملVariation in transcription factor binding among humans.
Differences in gene expression may play a major role in speciation and phenotypic diversity. We examined genome-wide differences in transcription factor (TF) binding in several humans and a single chimpanzee by using chromatin immunoprecipitation followed by sequencing. The binding sites of RNA polymerase II (PolII) and a key regulator of immune responses, nuclear factor kappaB (p65), were mapp...
متن کاملTranscription factor activation and mitogenic synergism in airway smooth muscle cells.
Simultaneous treatment of human airway smooth muscle (HASM) cells with lysophosphatidic acid (LPA) and epidermal growth factor (EGF) leads to strikingly synergistic stimulation of mitogenesis. The purpose of this study was to explore potential sites for signal integration mediating synergism, focusing on extracellular signal-regulated kinase (ERK) and transcription factors involved in prolifera...
متن کاملExpression and Clinical Significance of Activating Transcription Factor 3 in Human Breast Cancer
Objective(s): Breast cancer is the most common type of cancer among women worldwide. This study investigated the expression and clinical significance of activating transcription factor 3 (ATF3) in human breast cancer and its relationship with the clinical outcome of breast cancer. Materials and Methods : ATF3 expressions were detected in 114 primary breast cancer tissues and ...
