In this study, we tested the hypothesis that insulin-like growth factor-1 (IGF-1) modulates apoptosis in human breast cancer cells, HBL100, induced by diverse chemotherapeutic drugs. IGF-1 increased cell survival of HBL100 cells treated with 5-fluorouracil (antimetabolite), methotrexate (antimetabolite), tamoxifen (antiestrogen/antiproliferative), or(More)
MLH1 is an integral part of the mismatch repair complex, and the loss of this protein is associated with the acquisition of a mutator phenotype, microsatellite instability, and a predisposition to cancer. Deficiencies in the mismatch repair complex, including the loss of MLH1, result in elevated resistance to specific inducers of DNA damage, yet the(More)
Neuroblastoma (NB) cells in vitro are capable of bidirectional transdifferentiation, resulting in two distinct, yet reversible, phenotypes of neuroblastic (N-type) and nonneuronal (S-type) Schwann-like cells. Our previous studies suggested that the wild-type p53 protein is subject to differential regulation in a subset of neuronal cell types. To further(More)
