This study examined skin biopsies from a woman with Addison disease and found melanocytic hyperpigmentation in the epidermis, with a notable melanocyte/keratinocyte ratio indicating increased melanocyte presence in the arm compared to the thigh.

This study found that full-length Agouti protein modulates melanocortin receptor signaling through a dual mechanism involving competitive antagonism and receptor down-regulation, whereas the carboxyl-terminal fragment acts solely as a competitive antagonist.

This review discusses the role of zebrafish as a model for studying human hereditary pigmentary disorders and reports no new experimental results, emphasizing their genetic similarities and the genetic tools available.
