The expression of epidermal lipoxygenases and transglutaminase-1 is perturbed by NIPAL4 mutations: indications of a common metabolic pathway essential for skin barrier homeostasis.

Abstract excerpt

Autosomal recessive congenital ichthyosis (ARCI) is a heterogeneous group of skin barrier diseases due inter alia to mutations in transglutaminase-1 (TGM1), in lipoxygenases (LOXs) of the hepoxilin pathway, and in ichthyin, a putative Mg(2+) transporter encoded by the NIPAL4 gene. In search of a common pathogenic pathway for ARCI, we investigated the epidermal expression of TGM1, 12R-LOX, eLOX-3, and ichthyin in...
