The bHLH transcription factor MyoD, the prototypical master regulator of differentiation, directs a complex program of gene expression during skeletal myogenesis. The up-regulation of the cdk inhibitor p57kip2 plays a critical role in coordinating differentiation and growth arrest during muscle development, as well as in other tissues. p57kip2 displays a(More)
There is increasing evidence that proteins normally involved in the cell cycle play a role in the regulation of neuronal apoptotic death following various insults. However, it is not clear if the same mechanisms regulate cell death of oligodendrocytes as well. In this study, we investigated the mechanism of ceramide-induced apoptosis in primary rat(More)
Random bred Syrian hamsters given s.c. injections of SV40 small t deletion mutants dl883, dl884, and dl890 rapidly develop reticulum cell sarcomas in the abdominal cavity in addition to slowly developing s.c. fibrosarcomas at the site of virus inoculation. Injection of wild type SV40 s.c. induces only fibrosarcomas at the site of inoculation. In an attempt(More)
Poly(ADP-ribosyl)ation is a post-translational modification of various proteins and participates in the regulation of chromatin structure and transcription through complex mechanisms not completely understood. We have previously shown that PARP-1, the major family member of poly(ADP-ribose)polymerases, plays an important role in the cell cycle reactivation(More)
Hamster cells, transformed in vitro by SV40, have been reported to secrete an unidentified factor(s) that inhibits thymidine uptake (TU) by various normal cell types, including activated lymphocytes. It has been postulated that this apparent antiproliferative effect may play an in vivo role in the high tumorigenic capacity of SV40-transformed hamster cells.(More)
The D21S13 locus has shown linkage to a gene for familial Alzheimer disease (FAD) on chromosome 21 (St. George-Hyslop et al. 1987). The limited informativeness of probes for this locus have hindered precise mapping of the FAD locus and analysis of nonallelic heterogeneity in FAD (Schellenberg et al. 1988; St. George-Hyslop et al. 1987). We describe a new(More)
A variety of proto-oncogenes are present in normal cells, and many of these genes are expressed in different cell types in a tissue-specific and developmentally specific fashion. Although proto-oncogenes have normal functions, apparently related to cell proliferation and differentiation, these genes are able to cause cancer when they are expressed(More)
