After publication of this article [1], concerns were raised that the Fig 2C left Actin panel in this article [1] appears similar to the Fig 1F Actin panel of a later article [2]. The first author confirmed that these Actin panels are the same image, and the Fig 2C left p21 panel in [1] and the Fig 1F HIF-1α panel in [2] are from the same experiment and were run on the same blot. They provided the underlying image data associated with the left Fig 2C blots (S1-S3 Files). The first author stated that in S3 File, blots were cut before staining for the Fig 2C left panel p21 in [1] and Fig 1F HIF-1α in [2].

Additionally, it was noted that in [1], the concentration of doxorubicin used is listed as 1 µM in the “Time Course- Cell Death Following Acute Chemotherapy Treatment” section of the article, whereas in the remainder of the article the doxorubicin concentration is listed as 1 µg/mL. The first author stated that 1 µg/mL is the correct doxorubicin concentration, and that 1 µM was a typographical error.
