In the published article, there was an error about the source of berberine. A correction has been made to the section of Materials and Methods, “Cell Culture and Materials”, paragraph 1:
“Grape seed-OPCs (VX1 extract, EuroPharma USA, Green Bay, WI) and berberine (Berberine HCL, EuroPharma USA, Green Bay, WI) were dissolved in DMSO”.
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.
