In the review titled "Photoaging and Topical Tretinoin: Therapy, Pathogenesis, and Prevention," published in the October issue of the ARCHIVES (1997;133:1280-1284), the number 72 was inadvertently replaced with the number 92 on the bottom of page 1283. The sentence should have read: "The specificity of AP-1 in these MMP inductions was supported by a lack of messenger RNA, protein, or enzyme activity elevations of non–AP-1 regulated 72-kDa gelatinase."
