HMGB1 and Miyoshi myopathy: To further investigate whether the antichemoattractant effects of salicylates on MM cells are through COX inhibition or not, we compared the effects of ASA to indomethacin, a nonselective inhibitor of COX, and we found that ASA, but not indomethacin, inhibited HMGB1-induced motility of MM cells (Supplementary Figure S8).
