Translocations involving the IgH locus at chromosomal locus 14q32.3 are a common event in many B-cell malignancies. The translocations, which generally occur into JH and switch regions, are mediated by errors in the two developmentally regulated, lymphocyte-specific pathways: VDJ-and switch-mediated recombination. Dysregulation of cyclin D1 by a(More)
Treatment of chronic lymphocytic leukemia (CLL) remains a challenge due to the frequency of drug resistance amongst patients. Improving the delivery of chemotherapeutic agents while reducing the expression of anti-apoptotic Heat Shock Proteins (HSPs) within the cancer cells may facilitate in overcoming this drug resistance. We demonstrate for the first time(More)
A number of related enzymes like glutathione S-transferases (GSTs) and fatty acid ethyl ester synthases (FAEESs) have been implicated in detoxification and drug resistance. The anionic class of GSTs, pi, and closely related FAEES-III exhibit tissue-specific and developmentally regulated expression, and the former has been shown to be overexpressed or(More)
In Escherichia coli, efficient mutagenesis by UV requires the umuDC operon. A deficiency in umuDC activity is believed to be responsible for the relatively weak UV mutability of Salmonella typhimurium LT2 compared with that of E. coli. To begin evaluating this hypothesis and the evolutionary relationships among umuDC-related sequences, we cloned and(More)
Escherichia coli has two DNA repair methyltransferases (MTases): the 39-kilodalton (kDa) Ada protein, which can undergo proteolysis to an active 19-kDa fragment, and the 19-kDa DNA MTase II. We characterized DNA MTase II in cell extracts of an ada deletion mutant and compared it with the purified 19-kDa Ada fragment. Like Ada, DNA MTase II repaired(More)
The umuDC operon of Escherichia coli is required for efficient mutagenesis by UV light and many other DNA-damaging agents. The existence of a umuDC analog in Salmonella typhimurium has been questioned. With DNA probes to the E. coli umuD and umuC genes, we detected, by Southern blot hybridization, sequences similar to both of these genes in S. typhimurium(More)
lac operon fusions to DNA damage-inducible (din) loci were generated in Salmonella typhimurium LT2. Many of these din fusions were efficiently repressed by cloned Escherichia coli LexA, while others were not; all required RecA for induction. Several din fusions exhibited strong inducibility and will be useful in developing an SOS induction assay in S.(More)
Multiple endocrine neoplasia type 1 (MEN 1) is an autosomal dominant disorder that predisposes affected individuals to neoplasms of the parathyroid glands, endocrine pancreas, anterior pituitary, and carcinoids. The MEN1 locus has been localized by family studies to 11q13, flanked by markers PGA and D11S97. Eight new polymorphisms located in three separate(More)
We have combined genetic, radiation-reduced somatic cell hybrid (RRH), fluorescent in situ hybridization (FISH), and physical mapping methods to generate a contig of overlapping YAC, PAC, and cosmid clones corresponding to > 3 continuous Mb in 11q13. A total of 15 STSs [7 genes (GSTP1, ACTN, PC, MLK3, FRA1, SEA, HNP36), 4 polymorphic loci (D11S807, D11S987,(More)
