Description:
A mutated cyclin-dependent kinase 4 (CDK4) was identified as a tumor-specific antigen recognized by HLA-A2. 1-restricted autologous cytolytic T lymphocytes (CTLs) in a human melanoma. The mutated CDK4 allele was present in autologous cultured melanoma cells and metastasis tissue, but not in the patient's lymphocytes. The mutation, an arginine-to-cysteine exchange at residue 24, was part of the CDK4 peptide recognized by CTLs and prevented binding of the CDK4 inhibitor p16INK4a, but not of p21 or of p27KIP1. The same mutation was found in one additional melanoma among 28 melanomas analyzed. These results suggest that mutation of CDK4 can create a tumor-specific antigen and can disrupt the cell-cycle regulation exerted by the tumor suppressor p16INK4a.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wolfel, T -- Hauer, M -- Schneider, J -- Serrano, M -- Wolfel, C -- Klehmann-Hieb, E -- De Plaen, E -- Hankeln, T -- Meyer zum Buschenfelde, K H -- Beach, D -- New York, N.Y. -- Science. 1995 Sep 1;269(5228):1281-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Medizinische Klinik und Poliklinik, Johannes Gutenberg-Universitat, Mainz, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7652577" target="_blank"〉PubMed〈/a〉
