The proto-oncogene Ets-1 is a member of the Ets family of transcription factors which share a unique DNA binding domain, the Ets domain. Ets binding sites have been described on the promoters or enhancers of many proteinases and several Ets members transcriptionally regulate such promoters in transient cotransfection assays. Ets-1 is involved in both normal and pathological functions. Ets-1 is ...

Molecular dynamics (MD) simulations for Ets-1 ETS domain-DNA complexes were performed to investigate the mechanism of sequence-specific recognition of the GGAA DNA core by the ETS domain. Employing the crystal structure of the Ets-1 ETS domain-DNA complex as a starting structure we carried out MD simulations of: (i). the complex between Ets-1 ETS domain and a 14 base-pair DNA containing GGAA co...

BACKGROUND/AIMS To investigate the effect of taurine on cardiac remodeling induced by smoking. METHODS In the first step, rats were allocated into two groups: Group C (n = 14): control; Group T (n = 14): treated with taurine (3% in drinking water), for three months. In the second step, rats were allocated into two groups: Group ETS (n = 9): rats exposed to tobacco smoke; Group ETS-T (n = 9): ...

normal 0 false false false en-us x-none ar-sa background: cigarette smoke contains many oxidants and may alter the human reproduction by inducing oxidative stress (os) in both active and passive smokers. this study was designed to evaluate the effect of environmental tobacco smoke (ets) exposure on oxidative stress in the follicular follicle and the assisted reproduction outcomes. materials and...

The proteins of the Ets family are transcription factors involved in signal transduction, cell cycle progression, and differentiation. In this study, we report that thyroid cell neoplastic transformation is associated with a dramatic increase in ETS transcriptional activity, which is dependent on the accumulation of Ets-1, Ets-2, and other Ets-related proteins. Inhibition of ETS transactivation...

Elements responsible for the transcriptional activity of the human ATP synthase beta-subunit (ATPsyn beta) gene promoter have been studied through transient expression in HepG2 hepatoma cells of a CAT gene connected with various 5'-deletion mutants of the 5'-flanking region. Promoter activity was mostly dependent upon a single CCAAT motif as well as a nearby Ets domain binding region. This last...

The Drosophila pointed gene encodes two ETS transcriptional activators, pointedP1 and pointedP2, sharing a common C-terminal ETS domain. In the embryonic central nervous system pointedP2 is required for midline glial cell differentiation, whereas, in the eye, pointedP2 is essential for photoreceptor cell differentiation. Both vertebrate c-ets-1 and c-ets-2 gene ETS domains are highly homologous...

The proto-oncogene Ets-1 is a transcription factor that is known to regulate certain matrix metalloproteinases and plasminogen activator, which have been associated with malignant behaviors in solid carcinomas. We hypothesized that Ets-1 expression is also associated with tumor progression and a worse prognosis in lung carcinoma patients. To clarify the role of the Ets-1 proto-oncogene, the exp...

Ets-1 is a transcription factor that plays an important role in various physiological and pathological processes, such as development, angiogenesis, apoptosis and tumour invasion. In the present study, we have demonstrated that Ets-1 p51, but not the spliced variant Ets-1 p42, is processed in a caspase-dependent manner in Jurkat T-leukaemia cells undergoing apoptosis, resulting in three C-termi...
