The overexpression of SERPINH1, which showed a 5.7-fold upregulation in keloid margin in this study (P = .003), has been suggested to promote excessive collagen deposition in keloids.33 LGALS1 is a type of lectin that has been implicated in cell-cell and cell-matrix interactions and has been suggested to be involved in tumor progression, at least partly, through the induction of T-cell apoptosis.34 IGFBP7 shows a 2.8-fold upregulation in keloid margins (P = .022). This evidence concerns the gene IGFBP7 and keloid.
