Recombinant retroviruses (RV) have been widely used as vectors for clinical gene therapy of malignant brain tumors. Because of the very limited stability of these vectors in vivo, RV producing cells (VPC) are routinely used for intratumoral RV releas

The human egr - 1 gene encodes a zinc finger transcription factor induced by endogenous and exogenous stimuli such as growth factors, cytokines, and mitogens. Egr - 1 regulates other genes involved in growth and differentiation. The present study inv

The tumor suppressor protein p53 is induced upon DNA damage essentially by post-translational regulatory mechanisms, which lead to a substantial increase of p53 levels. To exploit this essential property of p53, we developed a novel reporter system f

Subcutaneous vaccination therapy with glioma cells, which are retrovirally transduced to secrete granulocyte-macrophage colony-stimulating factor (GM-CSF), has previously proven effective in C57BL/6 mice harboring intracerebral GL261 gliomas. However

Mutations in the dnaQ gene, which encodes the proofreading epsilon-subunit of the DNA polymerase III holoenzyme, lead to a mutator phenotype caused by enhanced error rates during DNA replication. In this paper, we studied the influence of ssb mutatio

The polA gene of Escherichia coli encodes DNA polymerase I that is involved in DNA replication and repair. Despite the wide knowledge about structure and function of DNA polymerase I, there is little insight into the regulatory mechanisms involved in

The initiation protein DnaA of Escherichia coli regulates its own expression autogenously by binding to a 9 bp consensus sequence, the dnaA box, between the promoters dnaAP1 and dnaAP2. In this study, we analysed dnaA regulation in relation to DNA da
