cAMP induces cell apoptosis in multiple myeloma and overcomes bortezomib resistance

An error has been found that we mistakenly used incorrect Actin controls in Figure 6C. Therefore, we would like to publish this Erratum to reflect this change. We sincerely apologize for this oversight and the additional work it may have caused. The corrected Figure 6 is shown below.

Figure 6.

8-CPT-cAMP enhanced the ER stress induced by bortezomib. The expression of CHOP and ATF4 (ER stress markers) was measured at the mRNA (A, B) and protein (C, D) levels after the treatment of H929 and H929-R cells with 8-CPT-cAMP, bortezomib, or their combination for 24 h in. H929-R, H929 bortezomib-resistant cells; ER, endoplasmic reticulum. *P < 0.05, **P < 0.01. The experiments were performed in triplicate.
