RESUMEN

Understanding how DNA binding proteins control global gene expression and chromosomal maintenance requires knowledge of the chromosomal locations at which these proteins function in vivo. We developed a microarray method that reveals the genome-wide location of DNA-bound proteins and used this method to monitor binding of gene-specific transcription activators in yeast. A combination of location and expression profiles was used to identify genes whose expression is directly controlled by Gal4 and Ste12 as cells respond to changes in carbon source and mating pheromone, respectively. The results identify pathways that are coordinately regulated by each of the two activators and reveal previously unknown functions for Gal4 and Ste12. Genome-wide location analysis will facilitate investigation of gene regulatory networks, gene function, and genome maintenance.

RESUMEN

We used genome-wide expression analysis to explore how gene expression in Saccharomyces cerevisiae is remodeled in response to various changes in extracellular environment, including changes in temperature, oxidation, nutrients, pH, and osmolarity. The results demonstrate that more than half of the genome is involved in various responses to environmental change and identify the global set of genes induced and repressed by each condition. These data implicate a substantial number of previously uncharacterized genes in these responses and reveal a signature common to environmental responses that involves approximately 10% of yeast genes. The results of expression analysis with MSN2/MSN4 mutants support the model that the Msn2/Msn4 activators induce the common response to environmental change. These results provide a global description of the transcriptional response to environmental change and extend our understanding of the role of activators in effecting this response.

RESUMEN

With the cooperation of the police agency of a small metropolitan community, 45 consecutive, disposed, false rape allegations covering a 9 year period were studied. These false rape allegations constitute 41% the total forcible rape cases (n = 109) reported during this period. These false allegations appear to serve three major functions for the complainants: providing an alibi, seeking revenge, and obtaining sympathy and attention. False rape allegations are not the consequence of a gender-linked aberration, as frequently claimed, but reflect impulsive and desperate efforts to cope with personal and social stress situations.

RESUMEN

Deviant sexual behavior has often been portrayed as the consequence of the frustration of legitimate sexual outlets. This study of date rapists reveals that these men, as a result of a hypersexual socialization process, are sexually very active, successful, and aspiring. These exaggerated aspiration levels are seen as responsible for instituting a high degree of sexual frustration. This acute relative deprivation, it is hypothesized, is a significant process responsible for precipitating these rape episodes.

RESUMEN

A replication of earlier studies of male sex aggression conducted during the mid 1950s basically finds little modification in incidence and frequency. Approximately 50% of a sample of university women report being victims of sexual aggression during the academic year. Major changes from the earlier research appear to be focused around the nature of the pair relationships and the characteristics of the offended females.
