Lentzsch S, Gries M, Janz M, Bargou R, Dörken B, Mapara MY. Macrophage inflammatory protein 1-alpha (MIP-1α) triggers migration and signaling cascades mediating survival and proliferation in multiple myeloma (MM) cells. Blood. 2003;101(9):3568-3573.

In Figures 5A (page 3571) and 6A (page 3572), the same western blot was used for pFKHR and pERK detection. Therefore, both blots have the same loading control, AFX, which is correctly shown in Figure 6A. In 1 lane (MIP-1α, 5 minutes, wortmannin), Figure 5A includes an incorrect negative control. This is due to cutting of the wrong loading control lane. Since the correct loading control is shown in Figure 6A, the error does not impact the scientific message of the study.

Also, in Figure 5A and B, “pFKRH” should be “pFKHR.”
