Seizure-suppressor mutations provide unique insight into the genes and mechanisms involved in regulating nervous system excitability. Drosophila bang-sensitive (BS) mutants present a useful tool for identifying seizure suppressors since they are a well-characterized epilepsy model. Here we describe the isolation and characterization of a new Drosophila(More)
RNA-binding proteins play critical roles in regulation of gene expression, and impairment can have severe phenotypic consequences on nervous system function. We report here the discovery of several complex neurological phenotypes associated with mutations of couch potato (cpo), which encodes a Drosophila RNA-binding protein. We show that mutation of cpo(More)
We recently reported a novel autosomal recessive mouse mutation designated nackt (nkt). Homozygous mutant mice have diffuse alopecia and a marked reduction in the proportion of CD4+ T cells in the thymus and peripheral lymphoid tissues. Here we show that the CD4 T-cell deficiency is due to a defect in the thymic microenvironment rather than the(More)
The two-stage model, initiation with 7,12-dimethylbenz[a]anthracene and promotion with 12-O-tetradecanoylphorbol-13-acetate, of mouse skin carcinogenesis has been the protocol of choice to study the genetic susceptibility to carcinogens, the outbred SENCAR mouse being the most widely used skin tumor-sensitive animal model. Squamous cell carcinomas (SCCs)(More)
Sixteen DNA microsatellites or simple sequence length polymorphisms (SSLPs), generated by polymerase chain reaction (PCR) were selected for use in the genetic quality control of the nine inbred SENCAR strains currently available. The SENCAR strains constitute a powerful tool for mechanistic studies of multi-stage skin carcinogenesis, as well as for studies(More)
Manufactured gas plant (MGP) residues, commonly known as coal tars, were generated several decades ago as a byproduct of residential and industrial gas production from the distillation of coal. Previous short-term exposure studies have shown MGP residues to be tumorigenic in mouse liver and lung. In order to gain further insight into carcinogenesis by(More)
