- The 7SK snRNA is dispensable for cell proliferation under standard growth conditions - After UV exposure, 7SK/P-TEFb is needed for proper stress response and cell survival - P-TEFb extracted from 7SK/P-TEFb triggers UV-induced general RNAPII pause release - P-TEFb from 7SK/P-TEFb supports activation of important UV-responsive genes
Transcription by RNA polymerase II in the context of chromatin
Ensuring that one gene's transcription does not inappropriately affect the expression of its neighbors is a fundamental challenge to gene regulation in a genomic context. In plants, which lack homologs of animal insulator proteins, the mechanisms …

Generating random genome annotations For different purposes, I often need to create random gene/features annotations. I usually need these annotations as a GRanges object (see the GenomicRanges package).
I searched a bit on the internet but couldn’t really find what I was looking for.
GGally is an extension of ggplot2. I use it mainly as a replacement/refinement of pairs in base R.
Here, I want to replace the default scatter plot used to compare 2 continuous variables with something nicer, especially adapted to plotting large number of points.
