| 摘要 | Albino Apostichopus japonicus occur both in the wild and in captivity. The offspring of albino A. japonicus also suffer from albinism. The formation of melanin in the melanocytes is dependant on microphthalmia-associated transcription factor (MITF). To investigate the role of MITF in controlling albinism, we cloned the full-length MITF cDNA from A. japonicus and compared MITF mRNA expression in albino and normal A. japonicus. In addition, we used light and electron microscopy to compare histological samples of normal and albino A. japonicus. The body wall of albino adults was characterized by significantly lower levels of MITF expression and lower numbers of epidermal melanocytes, which also contained less melanin. In albino juvenile offspring, MITF expression levels were significantly lower 32 d after fertilization and there were fewer, and less developed, epidermal melanocytes. Thus, we conclude that albino A. japonicus have fewer melanocytes and a reduced ability to synthesize melanin, likely because of lower expression of MITF. |
