Abstract

Serological analysis of recombinant tumor cDNA expression library (SEREX) is a powerful and widely used method to explore the cancer immune environment. In the present study, immunoscreening of normal testicular tissues and malignant mesothelioma (MM) cancer MSTO‑211H cell line cDNA libraries with sera from 5 MM patients led to the isolation of 16 independent antigens, which were designated ‘Korea Pusan‑Malignant Mesothelioma’ (KP‑MM)‑1 to ‑16. In total, 3/16 antigens were identified using the results of previous SEREX analyses, and 13 were newly identified. Of these, KP‑MM‑8, which was subsequently identified as amyotrophic lateral sclerosis 2 chromosome region candidate 11, was shown to be tissue‑restricted. Reverse transcription‑polymerase chain reaction demonstrated KP‑MM‑8 to be expressed strongly only in the normal testis, and weakly in the spleen, prostate, ovary, heart and skeletal muscle. In addition, KP‑MM‑8 mRNA was identified in MM cell lines, and in various other cancer cell lines, including MM (3/4), lung cancer (5/7), melanoma (5/7) and liver cancer (5/5) cell lines. Additionally, 2/16 antigens (KP‑MM‑2 and KP‑MM‑6) exclusively reacted with sera from cancer patients. However, KP‑MM‑8 reacted with 1 of 8 MM sera. Notably, 8/8 patients with MM and 8/8 normal individuals exhibited antibodies reactive to KP‑MM‑5, which was identified as cell division cycle 25B, a known oncogene. Overall, this data suggests that KP‑MM‑8 may be considered as a cancer/testis‑like antigen and KP‑MM‑5 as an immunogenic tumor antigen in MM patients.
