Corrigendum: Carnosol, a natural polyphenol, inhibits migration, metastasis, and tumor growth of breast cancer via a ROS-dependent proteasome degradation of STAT3 (Front. Oncol., (2019), 9, (743), 10.3389/fonc.2019.00743)

In the published article, there was an error in Figure 2 as published. The control image in Figure 2A (left panel) was previously published for a different drug as the experiments were performed in parallel and shared the same control. To eliminate any potential copyright issues, we have chosen to replace the control image in Figure 2A (control, left panel, blue square) with a new picture taken from a different field. The corrected Figure 2 and its caption appear below. Carnosol inhibits the invasion capability of MDA-MB-231 cells. (A) MDA-MB-231 cells were incubated for 24 h with or without 25μM carnosol and LY294002 (20μM). Cells that invaded into the matrigel were scored as described in Materials and Methods. (B) Quantification of invaded MDA-MB-231 into the matrigel. Values represent means ± SEM, n = 3 (**p < 0.005 and ***p < 0.001). The authors apologize for this error and state that this does not change the scientific conclusions of the article in any way. The original article has been updated.
