Research Abstract

Hailey-Hailey disease (HHD) and Darier disease (DD) are caused by mutations in the genes encoding the intracellular calcium pumps. In this study, we investigated the roles for intracellular Ca2+ homeostasis and epidermal differentiation in these calcium pumps, using cultured epidermal keratinocytes (KCs) derived from patients with HHD and DD. HHD KCs revealed the altered response of Ca2+ release from intracellular stores to ATP stimulation, but not by constitutive elevation of cytoplasmic Ca2+. The expressions of several calcium-binding proteins and epidermal differentiation-mediated proteins (e.g.calmodulin-like 5 and loricrin) were increased in HHD KCs compared to normal control.
