High-profile aging paper posts old erratum, requested by author more than one year prior

GenomeBioGenome Biology has partially retracted a high-profile paper about an epigenetic biomarker of aging – a year and a half after the author alerted the journal to a software coding error that invalidated one of its findings.

The paper, “DNA methylation age of human tissues and cell types,” garnered some media coverage and forms the basis of its author Steve Horvath‘s work on measuring human aging. It has been cited 73 times, according to Thomson Scientific’s Web of Knowledge. The article is also recommended on the post-publication peer review site Faculty of 1000.

The lengthy, peer-reviewed erratum notice, written by Horvath, refers to several figures and files, as well as a conclusion:

Researcher who threatened Retraction Watch with lawsuit corrects funding source for several papers

Ariel Fernandez, an Argentine chemist (who claims to hold the fastest-awarded PhD from Yale) and the subject of institutional investigations at multiple universities, has corrected several papers recently. What makes the moves particularly unusual — and interesting — is the stated reason for the amendments: disclaiming any funding from the National Institutes of Health for the work.

Fernandez was the recipient in 2005 of a $275,880 award “Protein packing defects as functional markers and drug targets.” The following year he received $294,217, and in 2007, $284,461, for the same four-year project, if we’re reading the link correctly.

Fernandez, readers of this blog might recall, threatened us with legal action when we wrote last spring about an expression of concern regarding his 2011 paper in BMC Genomics, “Subfunctionalization reduces the fitness cost of gene duplication in humans by buffering dosage imbalances.” According to that notice: Continue reading Researcher who threatened Retraction Watch with lawsuit corrects funding source for several papers
