High-level expression of Egr-1 and Egr-1-inducible genes in mouse and human atherosclerosis.
To understand the mRNA transcript profile in the human atherosclerotic lesion, RNA was prepared from the fibrous cap versus adjacent media of 13 patients undergoing carotid endarterectomy. cDNA expression arrays bearing 588 known genes indicated that lesions express unexpectedly high levels of the early growth response gene, Egr-1 (NGFI-A), a zinc-finger transcription factor that modulates a cl...
متن کاملMaintenance of long-term memory storage is dependent on late posttraining Egr-1 expression.
Expression of immediate-early genes, like Egr-1, has been shown to be induced by activity-dependent synaptic plasticity or behavioral training and is widely thought to play an important role in long-term memory (LTM) formation. However, little is known about the role of Egr-1 in the maintenance of memory storage. Here we show that dorsal hippocampal Egr-1 protein expression is upregulated betwe...
متن کاملNeuregulin-1 induces expression of Egr-1 and activates acetylcholine receptor transcription through an Egr-1-binding site.
Localization of acetylcholine receptors (AChRs) to neuromuscular synapses is mediated, in part, through selective transcription of AChR genes in myofiber synaptic nuclei. Neuregulin-1 (NRG-1) and its receptors, ErbBs, are concentrated at synaptic sites, and NRG-1 activates AChR synthesis in cultured muscle cells, suggesting that NRG-1-ErbB signaling functions to activate synapse-specific transc...
متن کاملDefining the functions of alveolar c-Met in late-stage emphysema Committee:
Krah 2 The alveolus is the functional unit of the lung consisting of two discrete cell populations, type 1 alveolar cells (AEC1s) and type 2 alveolar cells (AEC2s). AEC1s are the site of gas exchange, while AEC2s act as progenitors by differentiating into AEC1s during normal homeostasis and, more prominently, following injury [1,2]. Cigarette smoke (CS) induces apoptosis of alveoli, leading to ...
متن کاملAn Egr-1-specific DNAzyme regulates Egr-1 and proliferating cell nuclear antigen expression in rat vascular smooth muscle cells
The aim of the present study was to transfect rat aortic smooth muscle cells with an early growth response factor-1 (Egr-1)-specific DNAzyme (ED5), to observe its effect on Egr-1 and proliferating cell nuclear antigen (PCNA) expression and to elucidate the mechanism of ED5-mediated inhibition of vascular smooth muscle cell (VSMC) proliferation. VSMCs in primary culture obtained by tissue block ...
