Reduced expression of the antiapoptotic proteins of <i>Bcl‐2</i> gene family in the lesional epidermis of patients with Darier’s disease

Abstract

The alterations in the expression of Bcl-2 gene family proteins could be a crucial event for the activation of the apoptotic process in the lesional epidermis of DD patients and for the occurrence of the characteristic dyskeratotic keratinocytes. The question as to whether these alterations are associated with the ER Ca2+ depletion in DD or represent secondary phenomena unrelated to the genetic defect of this genodermatosis remains to be elucidated.
