Authors pull virus replication paper after they cannot replicate results

Researchers in China have retracted a 2016 paper exploring the replication behaviors of a retrovirus, after discovering that the key results could not be reproduced — possibly because their cell cultures had been contaminated.

The authors also cite a disagreement with a colleague, who they say contributed to the work but does not want to be listed as an author.

Here’s the retraction notice for “Nuclear import of prototype foamy virus transactivator Bel1 is mediated by KPNA1, KPNA6 and KPNA7,” published in the International Journal of Molecular Medicine: Continue reading Authors pull virus replication paper after they cannot replicate results

Authors use same images in two studies — one is retracted, the other flagged by journal

After researchers in China included the same images in two papers published online one month apart, one paper has been retracted, and the other flagged with an expression of concern. 

According to the retraction notice in the International Journal of Molecular Medicine (IJMM), the authors intended that the two different papers offered “different research perspectives.”

Meanwhile, the Chinese Medical Journal — which published the same images one month later — has issued an expression of concern (EOC), noting it “should not be considered as a statement regarding the validity of the work.” Both papers describe how cells regulate blood flow to the retina.

Normally, journals choose to retract the most recent paper containing duplicated images, but in this case, the IJMM paper was published online in February 2016, and the Chinese Medical Journal in March.

Journal pulls cancer paper that used others’ data; authors MIA

A journal has retracted a paper after a reader pointed out some of the data looked familiar — and the authors never responded to the allegations.

According to the retraction notice in the International Journal of Molecular Medicine, the reader showed the journal that the histological data in two of the figures were from another published paper by different researchers. But when the journal contacted the authors on several occasions, they didn’t hear back.
