Mark DePristo and colleagues report an analytical framework to discover and genotype variation using whole exome and genome resequencing data from next-generation sequencing technologies. They apply these methods to low-pass population sequencing data from the 1000 Genomes Project.
Sakari Kauppinen and colleagues report a method for silencing miRNA families in vivo. They find that seed-targeting 8-mer LNA oligonucleotides, termed tiny LNAs, can lead to long-term miRNA silencing in normal tissues and breast tumors in mice.
Francois Spitz and colleagues report GROMIT, a Sleeping Beauty transposon–based system for mapping genetic regulatory architecture in mouse. GROMIT is a regulatory sensor that responds to the activity of nearby enhancers.
Steven McCarroll and colleagues report an analytical framework for characterizing genome deletion polymorphism in populations, applied here to the low coverage genome sequences of 168 individuals from the 1000 Genomes Project. Their population-aware analysis enables structural inference with greater accuracy than previous methods.
