Muscle Regeneration and Myogenic Differentiation Defects in Mice Lacking TIS7

Volume 24, no. 8, p. 3514-3525, 2004. Page 3519, Fig. 3: After publication of this paper, we realized that some of the panels of this figure were not correctly labeled concerning the expression of laminin isoforms. In all three panels, “laminin α1” should read “laminins,” since the antibody used (Sigma L9393) was raised against a mixture of laminins purified from the EHS mouse sarcoma, and “laminin α2” should read “laminin B2 gamma 1 chain.” The protein expression data in panel b were double-checked by independent real-time PCR experiments using new, specific sets of primers and RNA isolated from soleus muscles. Subsequent experiments have confirmed that in the muscles of TIS7^−/− mice the expression of laminin B2 gamma 1 chain on both RNA and protein levels is down-regulated. We apologize for any difficulties or confusion that these errors may have caused for our colleagues.
