The Editors-in-Chief have retracted this article. After publication, concerns were raised regarding image irregularities in the Figures. Specifically,

  • Figure 1b: In the GAPDH panel, lanes 1-3 appear highly similar to lanes 4-6;

  • Figure 3c: In the GAPDH panel, lanes 1-3 appear highly similar to lanes 4-6;

  • Figure 4a: The western blot appears to contain a splice mark;

  • Figure 4b: Western blot lanes 1 and 6 appear highly similar PD

The Editors-in-Chief therefore no longer have confidence in the presented data.

Michael N. Sack agrees to this retraction. Kholiswa C. Ngumbela has not responded to any correspondence from the publisher regarding this retraction. The publisher has not been able to obtain a current email address for M. Faadiel Essop.
