Ultraviolet Light Exposure and Immunosuppression in Cutaneous Melanoma

2014-08-27 03:18:35 | BioPortfolio

Summary

This project seeks to understand differences in the serum vitamin D levels and immune status in cutaneous malignant melanoma patients with different UV exposure histories in New Mexico.

Description

It is well established that ultraviolet radiation (UV) exposure is related to the development of melanoma. There is also evidence that immune reactions are altered after UV exposure in the skin (locally) and perhaps throughout the body (systemically). Additionally, while the role of vitamin D and melanoma development has not been fully established, UV-B exposure is essential for vitamin D production in the skin. Increased sun exposure is also related to the presence of solar elastosis, which might protect (1) or improve survival from melanoma. Thus, melanoma represents a unique model for studying UV exposure, the immune system, and vitamin D. Malignant melanoma is an antigenic cancer; therefore, the role of UV exposure-induced immunosuppression and vitamin D production in the recognition, destruction and growth inhibition of cancerous melanocytes is worth further study.

To underscore the importance of this project, the Scientific Advisory Committee of the Melanoma Research Foundation and the Steering Committee of the Society of Melanoma Research have indicated a need to collect more human data on the host immune response mechanisms in melanoma and also to focus on the skin as a whole microenvironment, moving away from only in vitro experiments.

Medical and Biotech [MESH] Definitions

An unpigmented malignant melanoma. It is an anaplastic melanoma consisting of cells derived from melanoblasts but not forming melanin. (Dorland, 27th ed; Stedman, 25th ed)

Experimentally induced tumor that produces MELANIN in animals to provide a model for studying human MELANOMA.

A cellular subtype of malignant melanoma. It is a pigmented lesion composed of melanocytes occurring on sun-exposed skin, usually the face and neck. The melanocytes are commonly multinucleated with a "starburst" appearance. It is considered by many to be the in situ phase of lentigo maligna melanoma.

Found in large amounts in the plasma and urine of patients with malignant melanoma. It is therefore used in the diagnosis of melanoma and for the detection of postoperative metastases. Cysteinyldopa is believed to be formed by the rapid enzymatic hydrolysis of 5-S-glutathionedopa found in melanin-producing cells.

A melanosome-specific protein that plays a role in the expression, stability, trafficking, and processing of GP100 MELANOMA ANTIGEN, which is critical to the formation of Stage II MELANOSOMES. The protein is used as an antigen marker for MELANOMA cells.
