Fig 1: Prominently weakened cell junction components characterize SGR and AGR skin regions compared with GP areas under steady-state. Representative images for immunostaining and quantification of epidermal levels of KRT1, TGM5, CDSN, DSG1, CLDN1, OCLN, ABCA12, KLK5, and KLK7 in healthy GP, AGR, and SGR skin sections. Bar = 100 µm. Means ± 95% confidence intervals for protein levels are shown. (* p < 0.05, ** p < 0.01, *** p < 0.001, determined by one-way ANOVA followed by Sidac post hoc test) Abbreviations: ABCA12, ABC transporter 12B; AGR, apocrine gland-rich; CDSN, corneodesmosin; CLDN, claudin; DSG1, desmoglein 1; GP, gland-poor; KLK, kallikrein-related peptidase; KRT, keratin; OCLN, occludin; SGR, sebaceous gland-rich; TGM, transglutaminase.
