RETRACTED ARTICLE: Asiatic acid attenuates pre-neoplastic lesions, oxidative stress, biotransforming enzymes and histopathological alterations in 1,2-dimethylhydrazine-induced experimental rat colon carcinogenesis

Abstract Statement of Retraction: Asiatic acid attenuates pre-neoplastic lesions, oxidative stress, biotransforming enzymes and histopathological alterations in 1,2-dimethylhydrazine-induced experimental rat colon carcinogenesis We, the Editors and Publishers of Toxicology Mechanisms and Methods have retracted the following article:  Aktarul Islam Siddique, Vijay Mani, Sivaranjani Arivalagan, Nisha Susan Thomas & Nalini Namasivayam (2017) Asiatic acid attenuates pre-neoplastic lesions, oxidative stress, biotransforming enzymes and histopathological alterations in 1,2-dimethylhydrazine-induced experimental rat colon carcinogenesis, Toxicology Mechanisms and Methods, 27:2, 136-150, DOI: 10.1080/15376516.2016.1273422 The article is being retracted due to image manipulation in Figures 3 and 9, as follows: Figure 3: Panel E is a subsection of Panel B; Figure 3: Panels C and D appear to contain clone stamps; Figure 9: Panels A and B are the same image, with the frame of reference shifted; Figure 9: Panels Ai and Bi are the same image, with the frame of reference shifted; Figure 9: Panels E and F contain an overlapping section (panel E lower right corner, panel F upper left corner); Figure 9: Panels Ei and Fi contain an overlapping section (panel Ei lower right corner, panel Fi upper left corner). These findings are not explained by the content of the article and the authors were not able to provide original data that would support the integrity of their research. We have been informed in our decision-making by our policy on publishing ethics and integrity and the COPE guidelines on retractions. The retracted article will remain online to maintain the scholarly record, but it will be digitally watermarked on each page as “Retracted”.
