Mad2 is a component of the spindle checkpoint, which delays the onset of anaphase until all chromosomes are attached to the spindle. Mad2 formed a complex with Slp1, a WD (tryptophan-aspartic acid)-repeat protein essential for the onset of anaphase. When the physical interaction between the two proteins was disrupted, the spindle checkpoint was no longer(More)
Mutations in the human DNA mismatch repair gene MSH2 are associated with hereditary nonpolyposis colorectal cancer as well as a significant proportion of sporadic colorectal cancer. The inactivation of MSH2 results in the accumulation of somatic mutations in the genome of tumor cells and resistance to the genotoxic effects of a variety of chemotherapeutic(More)
Caracemide, MeCON(CONHMe)(OCONHMe) (I), is a novel anticancer drug. Since it was derived from acetohydroxamic acid (II), a known mutagen, its potential metabolites and related compounds were synthesized and tested for mutagenicities in S. typhimurium TA98 and TA100. These compounds were: MeNHCONH(OCONHMe) (III), MeCONH(OCONHMe) (IV), MeCONOH(CONHMe) (V),(More)
Somatic hypermutation (SHM) and class switch recombination (CSR) are initiated by activation-induced cytidine deaminase-mediated cytidine deamination of immunoglobulin genes. MutS homologue (Msh) 2-/- mice have reduced A-T mutations and CSR. This suggests that Msh2 may play a role in repairing activation-induced cytidine deaminase-generated G-U mismatches.(More)
