Chromosomes in human cancer cells are expected to initiate replication from predictably localized origins, firing reproducibly at discrete times in S phase. Replication products obtained from HeLa cells at different stages of S phase were hybridized to cDNA and genome tiling oligonucleotide microarrays to determine the temporal profile of replication of human chromosomes on a genome-wide scale....
Small supernumerary marker chromosomes (sSMC) are structurally abnormal chromosomes that cannot be unambiguously identified by banding cytogenetics. The objective of this study was to provide an overview of sSMC frequency and characterization in a context of infertility and to review the literature describing sSMC in relation with male and female infertility. Therefore, a systematic literature ...
Mitomycin C (MC) is a chemically reactive antibiotic derived from Streptomyces caespitosus. The drug selectively inhibits DNA synthesis (2, 15, 29, 34, 39, 40, 43, 44, 49) and degrades cellular DNA but does not affect the synthesis of R N A or protein (31, 33, 40). MC induces bacteriophage production in lysogenic bacteria (23, 29), increases the rate of genetic recombination among mutant forms ...
