A correction for Alirio Melendez, in Journal of Cellular Physiology

without comments

We’ve been covering the case of Alirio Melendez, three of whose papers have been retracted amidst questions about almost 70 studies. The latest development is a correction in the Journal of Cellular Physiology, which has already retracted one of his papers, of a study on which he was a co-author.

Here’s the correction for “Short dysfunctional telomeres impair the repair of arsenite-induced oxidative damage in mouse cells”:

In Newman et al., 2008, Figure 2 contained duplicate profiles in Fig 2H and 2 J. The correct Figure 2E to 2J is shown here. This error doesn’t have any influence on the data discussed and conclusions drawn in the article.

Figure 2. Figure 2 (E–J) FACS profiles of dual staining for Annexin V and propidium iodide to determine apoptosis and necrosis. Early and late passage G1-mTERC +/+ and G1-mTERC −/− MEFs were exposed to sodium arsenite (3.0 µg/ml) for 48 h and subjected to Annexin V staining. (E) Untreated mTERC +/+ MEFs; (F) arsenite-treated mTERC +/+ MEFs; (G) mTERC −/− (EP) MEFs; (H) arsenite-treated mTERC −/− (EP) MEFs; (I) untreated mTERC −/− (LP) MEFs; (J) arsenite-treated mTERC −/− (LP) MEFs. Annexin V staining in early apoptosis and dual staining in the late apoptosis in mTERC −/− (EP) MEFs were higher as compared to the mTERC +/+ MEFs at both early (data not shown) and late passages (F). Arsenite-treated mTERC −/− (EP) MEFs showed greater number of late apoptotic cells when compared to the untreated mTERC −/− (EP) MEFs and mTERC +/+ MEFs (H). Arsenite-treated G1-mTERC −/− (LP) MEFs displayed greater cell death by apoptosis (J).

The paper, which was first published online in 2007, has been cited 15 times, according to Thomson Scientific’s Web of Knowledge.
