    Description: Progesterone (PRE) or glucocorticoid receptor (GRE) DNA binding sites are often found clustered with binding sites for other transcription factors. Individual protein binding sites were tested without the influence of adjacent factors by analyzing isolated combinations of several transcription factor binding sites with PREs or GREs. All show strong synergistic effects on steroid induction. The degree of synergism is inversely related to the strength of the GRE. Thus, a steroid responsive unit can be composed of several modules that, if positioned correctly, act synergistically.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schule, R -- Muller, M -- Kaltschmidt, C -- Renkawitz, R -- New York, N.Y. -- Science. 1988 Dec 9;242(4884):1418-20.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Max-Planck Institut fur Biochemie, Martinsried, Federal Republic of Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3201230" target="_blank"〉PubMed〈/a〉

    Notes: Abstract Conditional mutagenesis in mice has recently been made possible through the combination of gene targeting techniques and site–directed mutagenesis, using the bacteriophage P1–derived Cre/loxP recombination system. The versatility of this approach depends on the availability of mouse mutants in which the recombinase Cre is expressed in the appropriate cell lineages or tissues. Here we report the generation of mice that express Cre in myeloid cells due to targeted insertion of the cre cDNA into their endogenous M lysozyme locus. In double mutant mice harboring both the LysMcre allele and one of two different loxP–flanked target genes tested, a deletion efficiency of 83–98 was determined in mature macrophages and near 100 in granulocytes. Partial deletion (16) could be detected in CD11c+ splenic dendritic cells which are closely related to the monocyte/macrophage lineage. In contrast, no significant deletion was observed in tail DNA or purified T and B cells. Taken together, LysMcre mice allow for both specific and highly efficient Cre–mediated deletion of loxP–flanked target genes in myeloid cells.
