Transcriptional control signals of a eukaryotic protein-coding gene

Abstract: Transcriptional control signals of a model eukaryotic protein-coding gene have been identified by a new procedure of in vitro mutagenesis. This method allows small clusters of nucleotide residues to be substituted in a site-directed manner without causing the addition or deletion of other sequences. Transcription assays of a systematic series of these clustered point mutants have led to the identification of three distinct control signals located within the 105-nucleotide residues immediately upstream from the point where transcription begins.

Absolute quantification by droplet digital PCR versus analog real-time PCR

Abstract: Nanoliter-sized droplet technology paired with digital PCR (ddPCR) holds promise for highly precise, absolute nucleic acid quantification. Our comparison of microRNA quantification by ddPCR and real-time PCR revealed greater precision (coefficients of variation decreased 37-86%) and improved day-to-day reproducibility (by a factor of seven) of ddPCR but with comparable sensitivity. When we applied ddPCR to serum microRNA biomarker analysis, this translated to superior diagnostic performance for identifying individuals with cancer.

The centromere paradox: stable inheritance with rapidly evolving DNA.

Abstract: Every eukaryotic chromosome has a centromere, the locus responsible for poleward movement at mitosis and meiosis. Although conventional loci are specified by their DNA sequences, current evidence favors a chromatin-based inheritance mechanism for centromeres. The chromosome segregation machinery is highly conserved across all eukaryotes, but the DNA and protein components specific to centromeric chromatin are evolving rapidly. Incompatibilities between rapidly evolving centromeric components may be responsible for both the organization of centromeric regions and the reproductive isolation of emerging species.

Veno-occlusive Disease of the Liver and Multiorgan Failure after Bone Marrow Transplantation: A Cohort Study of 355 Patients
