Title:  Yeast CAF-1 assembles histone (H3-H4) 2 tetramers prior to DNA deposition

What Caught Our Attention: Informative retraction notices can be infrequent, but rarer still are notices that fulfill an oft-ignored function: To be a source of learning for others in the field. Here, the authors offer a nearly 800-word “detailed description of the issues” with “some observations that may be useful for investigators conducting similar studies.” These authors embraced the retraction process, carefully explaining their findings or the lack thereof, for each figure from their now-retracted paper.     Continue reading Caught Our Notice: A retraction that is “useful for investigators”

Prompted by PubPeer, biologist corrects three papers

GeneA biologist has corrected three papers that are nearly a decade old, after concerns were raised on PubPeer.

A commenter first posted a comment about an image in one of the papers in 2013; after more comments on other papers appeared in November 2015, author Zoya Avramova at the University of Nebraska-Lincoln received emails alerting her to the threads. She has responded, including to the 2013 comment, noting “the said images should have been assembled more carefully.”

After repeating some of the experiments to verify the results, she has now issued corrections on three papers, about the genetics of model organism Arabidopsis. The papers share a first author, Abdelaty Saleh, who was a postdoc in Avramova’s lab at the time of the work.

The correction notice for “Dynamic and stable histone H3 methylation patterns at the Arabidopsis FLC and AP1 loci,” appearing in the July 2016 volume of Gene, explains:  Continue reading Prompted by PubPeer, biologist corrects three papers
