Tumour necrosis factor alpha (TNFα) is a potent cytokine that signals through nuclear factor kappa B (NFκB) to activate a subset of human genes. It is usually assumed that this involves RNA polymerases transcribing responsive genes wherever they might be in the nucleus. Using primary human endothelial cells, variants of chromosome conformation capture (including 4C and chromatin interaction ana...
In the last few years, the focus in ASR research has shifted from the recognition of clean read speech (i.e. WSJ) to the more challenging task of transcribing found speech like broadcast news (Hub-4 task) and telephone conversations (Switchboard). Available training corpora tend to become larger and more erroneous than before, as transcribing found speech is more difficult. In this paper we pre...
Capping is the first step in pre-mRNA processing, and the resulting 5'-RNA cap is required for mRNA splicing, export, translation, and stability. Capping is functionally coupled to transcription by RNA polymerase (Pol) II, but the coupling mechanism remains unclear. We show that efficient binding of the capping enzyme (CE) to transcribing, phosphorylated yeast Pol II (Pol IIp) requires nascent ...
Besides speaking, writing skills is another important skill that university students need to master. Students develop their in order cope with coursework. Nevertheless, more than just converting oral thoughts into written form. Online learning has pushed many changes take place for the teaching and of academic writing. The use technology facilitates On other hand, sometimes, teachers are unable...
We have studied the kinetics of transcription through a nucleosome core. RNA polymerase transcribes the first approximately 25 bp of nucleosomal DNA rapidly, but then hits a barrier and continues slowly to the nucleosomal dyad region. Here, the barrier disappears and the transcript is completed at a rapid rate, as if on free DNA, indicating that histone octamer transfer is completed as polymera...
Most eukaryotes contain many tandem repeats of ribosomal RNA genes of which only a subset is transcribed at any given time. Current biochemical methods allow for the determination of the fraction of transcribing repeats (ON) versus non-transcribing repeats (OFF) but do not provide any dynamical information and obscure any transcription activity at the single-cell level. Here, we use a fluoresce...
The recognition of mathematics notation by a computer is made difficult by the two-dimensional nature of the parsing problem as well as by the richness and ambiguity of the notation. Parsing mathematics typeset in TEX constitutes a simplified, idealized 2D recognition problem, allowing the recognition engine to concentrate more on semantic understanding. Choosing TEX as an input form for mathem...
MECP2, a relatively small gene located in the human X chromosome, was initially described with three exons transcribing RNA from which the protein MeCP2 was translated. It is now known to have four exons from which two isoforms are translated; however, there is also evidence of additional functional genomic structures within MECP2, including exons potentially transcribing non-coding RNAs. Accom...
