Chemoprevention Of Familial Melanoma, Vidhya Hariharan

Dissertations (6 month embargo)

Bleaching agents 4-tertiary butyl phenol (4-TBP) and monobenzyl ether of hydroquinone (MBEH) have been known to cause occupational vitiligo This project answers whether agents 4-TBP and MBEH can be used for prophylactic treatment of familial melanoma by being specifically toxic to melanocytes and activating an immune response against distant pigment cells. Cytotoxic experiments reveal that similar to 4-TBP, MBEH induces specific melanocyte death. To compare death pathways initiated by 4-TBP and MBEH, classical apoptotic hallmarks were evaluated in treated melanocytes. MBEH induced cell death without activating the caspase cascade or DNA fragmentation, showing that the death pathway is non-apoptotic. Release …
