Construction and Characterization of an Infectious Murine Gammaherpesivrus-68 Bacterial Artificial Chromosome
Here we describe the cloning of a sequenced WUMS isolate of murine gammaherpesvirus-68 (MHV-68, γHV-68, also known as MuHV-4) as a bacterial artificial chromosome (BAC). We engineered the insertion of the BAC sequence flanked by loxP sites into the left end of the viral genome before the M1 open reading frame. The infectious viruses were reconstituted following transfection of the MHV-68 BAC DN...
متن کاملMurine gammaherpesvirus 68 contains two functional lytic origins of replication.
A 1.25-kbp DNA fragment from the right side of the genome containing the lytic origin of replication (oriLyt) of murine gammaherpesvirus 68 (MHV-68) has been identified by a plasmid replication assay. Here we show that a mutant MHV-68 with a deletion of an essential part of this oriLyt, generated by using an MHV-68 bacterial artificial chromosome, was only slightly attenuated and still able to ...
متن کاملDistinct regions of allelic loss on chromosome 4 in human primary bladder carcinoma.
Accumulating evidence implicates the presence of putative tumor suppressor genes on human chromosome 4 that are potentially inactivated in the genesis of several different neoplasms. To accurately determine the frequency of allelic loss on both arms of human chromosome 4, we screened 282 fresh-frozen human bladder carcinomas for allelic loss. Loss of heterozygosity of at least one marker for ch...
متن کاملConjugal transfer in Lactococcus lactis of a 68-kilobase-pair chromosomal fragment containing the structural gene for the peptide bacteriocin nisin.
Nisin-producing transconjugants were generated by mating nisin-producing strains of Lactococcus lactis subsp. lactis with derivatives of L. lactis subsp. lactis LM0230. The sucrose-utilizing ability and reduced bacteriophage sensitivity were also transferred with the nisin-producing character. Pulsed-field gel electrophoretic analysis of genomic DNA from donor, recipient, and nisin-producing tr...
متن کاملEffect of vitamin E on preovulatory stage irradiated female mouse expressed as chromosomal abnormalities in generated embryos
Background: The present study has been carried out to investigate the effects of preovulatory stage gamma-irradiation of female mice in the absence or presence of vitamin E on numerical chromosome abnormalities in 8-cell embryos after mating with non-irradiated males. Materials and Methods: The 8-11 weeks adult female NMRI mice were whole body irradiated at preovulatory stage (post PMSG inject...
