In addition, RCAS1 expression is associated with the number of apoptotic lymphocytes adjacent tumour cells in lung cancer and Hodgkin's disease (Iwasaki et al, 2000; Ohshima et al, 2001), and RCAS1 expression is inversely related with the degree of intratumoral infiltration of lymphocytes (Suzuki et al, 2001). The gene discussed is EBAG9; the disease is lung carcinoma.
