Multiscale representation of genomic signals : Nature Methods : Nature Publishing Group

Interesting but addressing mappability issue is key! Might want to also use a non-analytic stat test….
Compared to wavelets, non-independence betw. scales, perhaps key for allowing pruning.

Exonic Transcription Factor Binding Directs Codon Choice and Affects Protein Evolution

Sunday, December 15th, 2013

QT:{{”
We found that ~15% of human codons are dual-use codons (“duons”) that simultaneously specify both amino acids and TF recognition sites. Duons are highly conserved and have shaped protein evolution, and TF-imposed constraint appears to be a major driver of codon usage bias.

Evidence of Abundant Purifying Selection in Humans for Recently Acquired Regulatory Functions
L Ward & M Kellis

In general we know that conservation across species and within humans are correlated. In this paper the authors focus on emphasize the exceptions to this trend. They show that although only ~5% of the human genome is conserved across mammals, regulatory regions in an additional 4% of the genomes are conserved amongst humans. They also show that some elements are conserved across mammals but lack functional activity from ENCODE data and also do not show purifying selection amongst humans. The authors pinpoint regulatory regions near color vision and nerve-growth genes for that show human-specific constraint. This has been criticized in various publications since there are other genes that are higher up in the authors’ list but harder to explain for lineage-specific constraint.

The haplotype-resolved genome and epigenome of the aneuploid HeLa cancer cell line Nature. 2013 – PubMed – NCBI

http://www.ncbi.nlm.nih.gov/pubmed/23925245

Contains a personal-genome like construction for HeLa
with 100X shotgun and then paired ends used for variant discovery and sequencing of pools of fosmid clones for haplotype resolution. Finally, low-freq. somatic and passage variants layered onto this.

“They found SNPs that regulate one gene (Ikaros) in different cell types, meaning they found different cis-regulatory regions for a single gene, that map to different pathways…. they used the cell-type specific information from ENCODE data.”
