Definitions
- the present invention relates to a novel cell transformation agent and the like.
- RMS Rhabdomyosarcoma
- RMS is one of the most common malignancies in childhood and is a sarcoma arising from immature mesenchymal cells. Since RMS is similar in shape to normal fetal skeletal muscle and expresses muscle-specific genes (J. Clin. Oncol., 13, 21 23-2139 (1995), Semin. Diagn. Pathol, 11 , 39-46 (1994)), and are thought to have arisen from immature cells that should become muscle tissue. RMSs are also classified into several subtypes due to their morphological differences. Although the survival rate of patients varies considerably due to morphological differences in sarcomas, the survival rate of children with RMS is generally 50-70. It is.
- RMS cell the fetal rhabdomyosarcoma cell line RD.
- RD cells LOHdoss of heterozygosity on chromosome 11 ⁇ 15 (Cancer Research, 57, 4493-4497 (1997)) and functional mutation due to base substitution of p53 (Biochem. Biophys. Res. , 17-24 (1994)) or a deletion mutation of ⁇ 16 (British J. Cancer, 79, 1032-1036 (1999)).
- it is difficult to make the final differentiation of RD cells into skeletal muscle cells which is presumed to play an advantageous role in obtaining the proliferation necessary for tumor formation. .
