Classical antineoplastic treatments such as chemotherapy or radiation can efficiently eradicate the majority of proliferating and genetically unstable malignant cells within neoplastic lesions. There is increasing evidence, however, that these regimens fre ...
1 In nine anaesthetized pigs we have studied the influence of intranasal or intrabronchial pretreatment with TASP-V, a neuropeptide Y (NPY) Y-2 agonist formed by the attachment of NPY 21-36 to a template-assembled synthetic peptide (TASP), on the functiona ...
Mammalian genomes contain numerous regulatory DNA sites with unknown target genes. We used mice with an extra β-globin locus control region (LCR) to investigate how a regulator searches the genome for target genes. We find that the LCR samples a restricted ...
Recently, a new method for the specific covalent labeling of fusion proteins in vitro and in living cells has been developed. This method is based on the unusual mechanism of a DNA repair protein: the O6-alkylguanine DNA alkyltransferase (AGT). In addition ...
Computer analysis of a conserved domain, BRCT, first described at the carboxyl terminus of the breast cancer protein BRCA1, a p53 binding protein (53BP1), and the yeast cell cycle checkpoint protein RAD9 revealed a large superfamily of domains that occur p ...
The design and synthesis of chem. probes to study and to elucidate complex biol. problems is becoming an increasingly important field in chem. We are interested in the repair of O6-alkylated guanines in DNA, a DNA lesion that results from alkylation by S-a ...
Chromatin remodeling is fundamental for B-cell differentiation. In the present study, we explored the role of KAP1, the cofactor of KRAB-ZFP transcriptional repressors, in this process. B-lymphoid-specific Kap1-KO mice displayed reduced numbers of mature B ...
In cells, DNA is routinely subjected to significant levels of bending and twisting. In some cases, such as under physiological levels of supercoiling, DNA can be so highly strained, that it transitions into non-canonical structural conformations that are c ...
Gadd45alpha is a nuclear protein encoded by a DNA damage-inducible gene. Through its interactions with other proteins, Gadd45alpha participates in the regulation of DNA repair, cell cycle, cell proliferation, and apoptosis. The NMR structure of human Gadd4 ...

The DNA and RNA helicase UPF1 is well known for its central role in Nonsense Mediated RNA Decay (NMD), which promotes degradation of mRNAs containing premature stop codons. However, we have recently demonstrated that human UPF1 is also essential for DNA re ...
