We have examined the effects of a siRNA targeting the Egr-1, alone or in combination with the breast cancer therapeutic camptothecin (Cpt), in suppressing breast cancer cell survival and anchorage-independent growth in the breast cancer cell lines SK-BR3 and MCF-7. In mammary and lung tumors, as well as most normal tissues, Egr-1 expression is low, suggesting a possible relation between the low...

Endothelial cell activation and dysfunction underlie many vascular disorders, including atherosclerosis, tumor growth, and sepsis. Endothelial cell activation, in turn, is mediated primarily at the level of gene transcription. Here, we show that in response to several activation agonists, including vascular endothelial growth factor (VEGF), tumor necrosis factor-alpha, and thrombin, endothelial...

During herpes simplex virus (HSV) latency, in neurons of the nervous system, a single family of viral transcripts (the Latency-Associated Transcripts or LATs) are synthesized. Within the LAT promoter region, we have identified a consensus sequence for the EGR proteins in an unusual position immediately downstream of the TATA box. The early growth response (EGR) proteins are rapidly induced in c...

Previously, we demonstrated that cysteamine releases endothelin-1 in the rat duodenal mucosa, followed by increased expression of early growth response factor-1 (egr-1). We hypothesized that egr-1 is a key mediator gene in the multifactorial mechanisms of duodenal ulcer development and healing because its protein, transcription factor product Egr-1, regulates the expression of angiogenic growth...

AIMS To understand the mechanisms of Early Growth Response Protein 1 (Egr-1) induction upon HSV-1 lytic infection and its roles in regulating viral gene expression and replication. STUDY DESIGN Rabbit corneal cell line SIRC and other cell lines were infected by HSV-1 to investigate the Egr-1 induction and its occupancy on the viral genome in different conditions. UV-inactivated HSV-1 and a re...
