Immediately early gene
Immediate early genes (IEGs) are genes which are activated transiently and rapidly in response to a wide variety of cellular stimuli. They represent a standing response mechanism that is activated at the transcription level in the first round of response to stimuli, before any new proteins are synthesized. … Zobacz więcej The earliest identified and best characterized IEGs include c-fos, c-myc and c-jun, genes that were found to be homologous to retroviral oncogenes. Thus IEGs are well known as early regulators of cell growth and … Zobacz więcej Expression of IEGs occurs in response to internal and external cell signals, occurring rapidly without the need to synthesize new transcription factors. The genetic sequences of … Zobacz więcej Expression of IEGs is involved in neuronal activity and specifically memory formation, neuropsychiatric diseases, and behavioral activities. … Zobacz więcej • Activation of Immediate Early Genes by Drugs of Abuse a monograph published by the National Institute on Drug Abuse • Immediate-Early+Genes at the U.S. National … Zobacz więcej Activation of gene transcription is a complex system of signal cascades and recruitment of necessary components such as RNA polymerase and transcription factors. … Zobacz więcej Human Cytomegalovirus (HCMV) Human Cytomegalovirus is a prevalent beta herpesvirus that remains in the latent state, going unnoticed in healthy individuals with serious consequences if the individual is immunocompromised. The virus cycles in … Zobacz więcej WitrynaNine homologous regions of highly repetitive sequences are found in the genome. Functional studies have identified several WSSV genes, including three immediately early genes, three latency-related genes and an anti-apoptosis gene. WSSV genes are classified as early genes or late genes according to their expression patterns. These …

Witryna23 lut 2024 · MyD88 deletion impairs liver regeneration by attenuating the activation of NF-κB and decreasing immediately early gene expression and TNF-α and IL-6 production in KCs after PHx; these findings highlight that TLRs/MyD88 signaling pathways are crucial for PHx-induced liver regeneration [9, 10]. WitrynaThe transcriptional program induced by growth factor stimulation is classically described in two stages as follows: the rapid protein synthesis-independent induction of immediate-early genes, followed by the subsequent protein synthesis-dependent induction of secondary response genes. In this study, we obtained a comprehensive view of this …
