Comprehensive identification of DNA cis-regulatory elements is crucial for a predictive understanding of transcriptional network dynamics. Strong evidence suggests that these DNA sequence motifs are highly conserved between related species, reflecting strong selection on the network of regulatory interactions that underlie common cellular behavior. Here, we(More)
Complete information regarding transcriptional and posttranscriptional gene regulation in stem cells is necessary to understand the regulation of self-renewal and differentiation. Alternative splicing is a prevalent mode of posttranscriptional regulation, and occurs in approximately one half of all mammalian genes. The frequency and functional impact of(More)
Development of highly anticipated stem cell-based therapies requires a detailed understanding of mechanisms regulating biological properties of these cells. Comprehensive identification of all biological molecules produced in stem cells is an important step toward this goal. During the past several years, microarray studies have essentially identified genes(More)
The N-terminal fusion peptide (FP) of human immunodeficiency virus-1 (HIV-1) is a potent inhibitor of cell-cell fusion, possibly because of its ability to recognize the corresponding segments inside the fusion complex within the membrane. Here we show that a fusion peptide in which the highly conserved Ile(4), Phe(8), Phe(11), and Ala(14) were replaced by(More)
Embryonic stem (ES) cells hold great promise for the future of medicine. To elucidate the molecular mechanisms that control ES cell self-renewal and differentiation, a comprehensive knowledge of the molecules involved in these processes is required. Here we describe an effective approach for genomewide identification of functionally active genes in ES(More)
One day, my supervising professor came to me in the lab, pointing to an article in a prestigious research journal, and indicating that we must learn the methodology described in the paper in order to implement it in our laboratory. Back then, in 2005, I was a graduate student in a biology lab at Princeton University, New Jersey. I did my best, but(More)
