First paper from our lab – Ancient deletions strike again and mysterious ways of adaptive forces

We have our first paper from the Buffalo laboratory published at Molecular Biology and Evolution (link here, it is Open Access). The paper describes polymorphic human deletions that are shared with Neandertals or Denisovans. Most of these deletions are not introgressed from ancient hominins, but rather have been lingering around since before Human/Neandertal/Denisovan ancestor. As expected majority … Continue reading First paper from our lab – Ancient deletions strike again and mysterious ways of adaptive forces

New Paper in Genome Research: Analysis of variable retroduplications in human populations suggests coupling of retrotransposition to cell division

We have a new paper regarding variation of retrotransposed genes among healthy individuals: In primates and other animals reverse transcription of mRNA followed by genomic integration creates retroduplications. Expressed retroduplications are either 'retrogenes' coding for functioning proteins or expressed 'processed pseudogenes', which can function as noncoding RNAs. To date, little is known about the variation … Continue reading New Paper in Genome Research: Analysis of variable retroduplications in human populations suggests coupling of retrotransposition to cell division

New Paper in PNAS: Primate genome architecture influences structural variation mechanisms and functional consequences

Our efforts to resequence and analyze primate genomes with a focus on genomic structural variation has now been published. Here is the link for the paper and here is the link for the curated datasets. The study, I think, is a major step forward to understand evolution of primate genomes. Now that several papers from Eichler … Continue reading New Paper in PNAS: Primate genome architecture influences structural variation mechanisms and functional consequences

New paper in PLoS Genetics – Balancing Selection shaping the distribution of a common deletion variant

Finally, our manuscript entitled "Balancing selection on a Regulatory Region Exhibiting Ancient Variation That Predates Human–Neandertal Divergence" was published in PLoS Genetics. You can find it here... It is Open Access. Also, link to the post regarding the manuscript in Dienekes' Anthropology Blog. Note the several interesting points that commentators were raising. Another recent blog post … Continue reading New paper in PLoS Genetics – Balancing Selection shaping the distribution of a common deletion variant

Genomeweb article on our work

Some of our work has been highlighted in a feature article in GenomeWeb: From the article entitled "Copy Machines": --- CNVs also have potentially significant implications for understanding evolutionary processes, Lee notes, citing a recent paper that he and his fellow Harvard researchers Rebecca Iskow and Omer Gokcumen published in Trends in Genetics in which they suggest that, although … Continue reading Genomeweb article on our work
