| Research Abstract |
We have investigated the elastin metabolism in anetoderma patient using human elastin cDNA as a probe. The patient showed multiple atrophic macules in the skin which lack elastic fibers on the histochemical observation. Assay of crude elastin content in the skin showed a remarkable reduction in the patients skin the fibroblasts from the patient and normal control skin were grown and RNA was isolated by 6M SH-Hcl and analyzed by northern blot analysis, using a human elastin cdna as a probe. No difference of elastin mRNA content between the patient and control was found. The result indicated that the metabolic defect in this disease is in the post-translational step of elastin synthesis, not in the transcriptional step.
