The c-Myc target gene PRDX3 is required for mitochondrial homeostasis and neoplastic transformation.
Deregulated expression of the c-Myc transcription factor is found in a wide variety of human tumors. Because of this significant role in oncogenesis, considerable effort has been devoted to elucidating the molecular program initiated by deregulated c-myc expression. The primary transforming activity of Myc is thought to arise through transcriptional regulation of numerous target genes. Thus far...
متن کاملComparison of the Initial Treatment Results of N-myc Positive and N-myc Negative Neuroblastoma Patients
Background: Neuroblastoma is the most common extra cranial malignant solid tumor of childhood. Various molecular and cytogenetic factors have been implicated in the pathogenesis of neuroblastoma, some of which have proven useful in predicting clinical behavior. Over expression of the oncogen N-myc, is an important indicator of prognosis. Materials and Methods: Our study was performed from 20...
متن کاملNeoplastic transformation of immortalized human epidermal keratinocytes by ionizing radiation.
Efforts to investigate the progression of events that cause human cells to become neoplastic in response to ionizing radiation have been aided by the development of tissue culture systems of epithelial cells. In the present study, nontumorigenic human epidermal keratinocytes immortalized by adenovirus type 12 and simian virus 40 have been transformed by exposure to x-ray irradiation. Such trans...
متن کاملTransactivation of the human c-myc gene by c-Myb.
We analyse the contribution of six Myb-binding sites in the upstream c-myc sequences to transactivation by co-transfection assays. Surprisingly, deletion of the six Myb-binding sites did not influence the transactivation of c-myc by c-Myb protein. Instead, the strongest transactivation was observed with a c-myc reporter plasmid which contains only 450 bp of exon 1 including the c-myc promoter P...
متن کاملNeoplastic transformation induced by carbon ions.
PURPOSE The objective of this experiment was to compare the oncogenic potential of carbon ion beams and conventional photon beams for use in radiotherapy. METHODS AND MATERIALS The HeLa X human skin fibroblast cell line CGL1 was irradiated with carbon ions of three different energies (270, 100, and 11.4 MeV/u). Inactivation and transformation data were compared with those for 15 MeV photons. ...
