| Research Abstract |
To apply the analysis using laser microdissection to skin diseases, we first compared mRNA expression between the lower and upper epidermis. When we examined filaggrin mRNA expression as a representative gene expressed only in the granular layer, the analysis using laser microdissection clearly demonstrated more abundant expression of filaggrinmRNA in the upper epidermis than in the lower epidermis. Next, we demonstrated augmented expression of mRNA related with the excretion of iron from inside to outside of the cell in the course of keratinization, which corresponds with the iron distribution in the epidermis. Finally, we examined immune-related gene, RANKL mRNA expression in extramammary Paget's disease. We could demonstrated more RANKL mRNA in the epidermis containing Paget's cells than the normal epidermis
