Erratum: Enhanced anti-tumor activity and cytotoxic effect on cancer stem cell population of metformin-butyrate compared with metformin HCl in breast cancer (Oncotarget (2016) 7 (38500-38512) DOI: 10.18632/oncotarget.9522)

Abstract

This article has been corrected: Due to errors during figure assembly, the data on â-actin in BT20, MB231, and Hs578T cells in Figure 2A, and the data on Hsc70 in BT20, MB231, and Hs578T cells in Figure 3C, are mistakenly identical. However, the original data is unavailable. In light of this, a new set of data was submitted for this correction as shown in the updated Figure 3 below. At the request of Oncotarget, the Seoul National University Research Integrity Committee has investigated the case and concluded: This error is not serious, as the above data had no direct impact on the results and conclusions of the study⋯. The action is considered an inappropriate research practice per Article 12-1 of the school's Research Ethics Guidelines 'Falsification of research data due to error without serious impact on the study,' and the degree of violation of research integrity is determined to be relatively minor in light of the details of this case as described above. (Figure Presented).
