Ahmad, R., J. Sylvester, M. Ahmad, and M. Zafarullah. 2009. Adaptor proteins and Ras synergistically regulate IL-1-induced ADAMTS-4 expression in human chondrocytes. J. Immunol. 182: 5081–5087.

ADAMTS was incorrectly defined as “a dystrophin and metalloproteinase with thrombospondin motif” in the following locations: the abbreviations footnote, the first sentence of the Abstract, and the second sentence of the second paragraph of the Introduction.

The correct term is, “a disintegrin and metalloproteinase with thrombospondin motif.”
