Comparison meaningful functions acting on some real interval E are completely described as transformed coordinate projections on minimal invariant subsets. The case of monotone comparison meaningful functions is further specified. Several already known results for comparison meaningful functions and invariant functions are obtained as consequences of our description. [less ▲]

The candidate human tumor suppressor gene cyclin C is a primary target of the anti-proliferative hormone 1alpha,25-dihydroxyvitamin D3 [1alpha,25(OH)2D3], but binding sites for the 1alpha,25(OH)2D3 receptor (VDR), so-called 1alpha,25(OH)2D3 response elements (VDREs), have not yet been identified in the promoter of this gene. We screened various cancer cell lines by quantitative PCR and found that the 1alpha,25(OH)2D3 inducibility of cyclin C mRNA expression, in relationship with the 24-hydroxylase (CYP24) gene, was best in MCF-7 human breast cancer cells. To characterize the molecular mechanisms, we analyzed 8.4 kb of the cyclin C promoter by using chromatin immunoprecipitation assays (ChIP) with antibodies against acetylated histone 4, VDR and its partner receptor, retinoid X receptor (RXR). The histone 4 acetylation status of all 23 investigated regions of the cyclin C promoter did not change significantly in response to 1alpha,25(OH)2D3, but four independent promoter regions showed a consistent, 1alpha,25(OH)2D3-dependent association with VDR and RXR over a time period of 240 min. Combined in silico/in vitro screening identified in each of these promoter regions a VDRE and reporter gene assays confirmed their functionality. Moreover, re-ChIP assays monitored simultaneous association of VDR with RXR, coactivator, mediator and RNA polymerase II proteins on these regions. Since cyclin C protein is associated with those mediator complexes that display transcriptional repressive properties, this study contributes to the understanding of the downregulation of a number of secondary 1alpha,25(OH)2D3-responding genes.

Previous studies that describe the existence and dimensions of the digital divide call attention to the potential negative consequences of not having access to a computer and not being online. Missing from these studies, however, is a more thorough investigation of how the effect of race/ethnicity on computer ownership is mediated by associated factors and how these effects have changed across time. The current study attempts to fill these gaps. Using Current Population Survey data, from 1984 to 2003, I estimate a series of logistic regression models on computer ownership at the household level. After controlling for demographic, household composition, and socioeconomic variables, the gap between Black and Hispanic households in relation to White households remains statistically significant. For Asian households, the racial effect is explained by the variables in the models. The implications of these findings are discussed and suggestions are made for future research. [less ▲]

Solving relevant biological problems requires answering complex questions. Addressing such questions traditionally implied the design of time-consuming experimental procedures which most of the time are not accessible to average-sized laboratories. The current trend is to move towards a multidisciplinary approach integrating both theoretical knowledge and experimental work. This combination creates a powerful tool for shedding light on biological problems. To illustrate this concept, we present here a descriptive example of where computational methods were shown to be a key aspect in detecting crucial players in an important biological problem: the dimerization of chemokine receptors. Using evolutionary based sequence analysis in combination with structural predictions two CCR5 residues were selected as important for dimerization and further validated experimentally. The experimental validation of computational procedures demonstrated here provides a wealth of valuable information not obtainable by any of the individual approaches alone. [less ▲]
