Correction: Sesquiterpene lactones downregulate G2/M cell cycle regulator proteins and affect the invasive potential of human soft tissue sarcoma cells

Abstract

Figures

Full text

After publication of this article [1], concerns were raised regarding Figs 4-5. Specifically:

The corresponding author stated that the β-actin blot for dehydrocostus lactone shown in Fig 4B of [1] is incorrect, whereas the β-actin blot for costunolide in Fig 4B and all panels in Fig 5 of [1] are correct. A revised version of Fig 4 is provided here, in which the appropriate β-actin blots are shown for each individual sarcoma cell line. The original, uncropped blots underlying the updated Fig 4 and Fig 5 in [1] are provided here in S1 File, and the individual-level quantitative data underlying Fig 4A are provided in S2 File.

The corresponding author further stated that the β-actin panels are intentionally duplicated between Fig 5 in [1] and the updated Fig 4, as they are derived from the same membrane, which was cut into strips prior to antibody incubation and subsequently probed with the respective antibodies for analysis.
