| melanogenesis |
Melanogenesis is the production of the pigment melanin, responsible for skin colour. It is triggered by the damaging effect of ultraviolet rays. Ultraviolet rays penetrate the skin and damage DNA; thymidine dinucleotides (pTpT) fragments from damaged DNA will trigger release of the hormone alpha-MSH, which can then bind to melanocytes to cause them produce melanin. Melanin vesicles from the melanocytes are then transferred to surrounding keratinocytes. ...

| melanomas |
The most serious and least common form of skin cancer. Melanomas usually grow out of moles (dark raised areas) in the skin cells (called melanocytes) that produce pigment, and can spread to the internal organs. Although people can die from melanoma, it can be easily identified and if caught early, can be treated.
