Zebrafish as a Model System to Study Heritable Skin Diseases

Heritable skin diseases represent a broad spectrum of clinical manifestations due to mutations in ∼500 different genes. A number of model systems have been developed to advance our understanding of the pathomechanisms of genodermatoses. Zebrafish (Danio rerio), a freshwater vertebrate, has a well-characterized genome, the expression of which can be easily manipulated. The larvae develop rapidly, with all major organs having largely developed by 5–6 days post-fertilization, including the skin which consists at that stage of the epidermis comprising two cell layers and separated from the dermal collagenous matrix by a basement membrane zone. Here, we describe the use of morpholino-based antisense oligonucleotides to knockdown the expression of specific genes in zebrafish and to examine the consequent knockdown efficiency and skin phenotypes. Zebrafish can provide a useful model system to study heritable skin diseases.
