Cell is looking into whether the authors of a widely hailed study published last week claiming to have turned human skin cells into embryonic stem cells manipulated images inappropriately, Retraction Watch has learned.
The potential image problems came to light on PubPeer, a site designed to allow for post-publication peer review. A commenter, identified as Peer1, identified “several examples of image reuse which might be of interest to PubPeer members and readers:” Read the rest of this entry »

Two Expressions of Concern in Blood for MD Anderson’s Aggarwal, who has threatened to sue Retraction Watch
Bharat Aggarwal, the MD Anderson researcher who has threatened to sue us while under investigation by his institution for alleged misconduct, now has two Expressions of Concern in addition to two corrections and two unexplained withdrawals.
Both of the papers were published in Blood. The Expression of Concern for “Gambogic acid, a novel ligand for transferrin receptor, potentiates TNF-induced apoptosis through modulation of the nuclear factor-κB signaling pathway,” reads: Read the rest of this entry »
