Definitions
- the present invention relates to a novel diagnostic kit and diagnostic method for malignant melanoma.
- Melanoma is a type of skin cancer called malignant melanoma. Although there are various types of skin cancer, melanoma is the highest grade of skin cancer and is very feared. Among the cells that make up the skin, there are cells that produce melanin pigments, which are called pigment cells (melanocytes), but those cells that have become cancerous are melanomas.
- melanocytes pigment cells
- Melanoma occurs in people of all ages, but it occurs more often when people are over 40 years old, with the highest number in the 60s to 70s. Although the incidence of children is very small, it does not mean that they do not occur, and there is a tendency that young people in the 20s to 30s have been increasing recently. Genders tend to be more common in both men and women. The area where Japanese melanoma is likely to occur accounts for about 30%, where the sole of the foot (the back of the foot) is the most common. A feature of the Japanese is that they can do a lot on the toes and fingernails. In addition, it occurs on any skin, including the body, hands, feet, face, and head, as in Westerners.
- glypican-3 (Glypican-3; GPC3) secretory protein, which was detected in the serum of 40% hepatocellular carcinoma patients and 40% melanoma patients using ELISA.
- GPC3 glypican-3; GPC3
- can be detected and reported to be useful as a new tumor marker for hepatocellular carcinoma Nakatsura, T. et al., Biochem. Biophys. Res. Commun. 306, 16-25, 2003; and Nakatsura, T. et al., Clin. Cancer Res. 10,6612-6621, 2004).
- SPARC Secreted protein, acidic rich in cysteine
- BM-40 additional name osteonectin
- SPARC is a cell interstitial glycoprotein having various functions. Its main functions include cell adhesion prevention, cell growth inhibition, and cell stroma regulation. (Bradshaw and Sage, J. Clin. Invest, 107: 1049-1054,2001; and Brekken and Sage, Matrix Biol., 2001; 19: 816 -827) Cells by binding interstitial structural proteins such as collagen It regulates the interaction between the stroma and the cells.
- SPARC in adults is highly expressed in sites where bones, platelets, wound sites or tumors are repeatedly remodeled. Many reports have been made on the relationship between SPARC and tumors in various carcinomas, and tumor cells or host stromal cells and inflammatory cells in tumor tissues express SPARC.
- Ledda et al. Reported in immunohistochemical examination that SPARC expression in human melanoma correlates with tumor progression. (Ledda et al., J. Invest. Delmatol., 108, 210-214, 1997).
