Chromosome-Scale Selective Sweeps and Genomic Diversity in C. elegans
Andersen, Gerke et al., Nature Genetics
Researchers at Princeton University and elsewhere discuss the effects of chromosome-scale selective sweeps on genomic diversity in Caenorhabditis elegans. Taking a high-throughput selective sequencing approach on a collection of 200 wild C. elegans strains, the team found that the nematode's "genome variation is dominated by a set of commonly shared haplotypes on four of its six chromosomes, each spanning many megabases." Further, the team reports on its population genetic modeling experiments, which showed that "this pattern was generated by chromosome-scale selective sweeps that have reduced variation worldwide; at least one of these sweeps probably occurred in the last few hundred years," it writes.
University of Iowa Sues Abbott Claiming Humira Manufacture Infringes CMV Promoter IP
The suit, filed by the UI Research Foundation, claims that Abbott has infringed one or more claims of the patents by manufacturing its billion-dollar blockbuster monoclonal antibody Humira, which is used to treat a variety of autoimmune diseases.
