In particular, it has been reported that lymphoma cell lines (19–20) and myeloid/lymphoid cells obtained from leukemia patients (5,20) express high levels of TSPO, and ovarian, hepatic and colonic carcinomas, as well as glioma (7–8,10–12) have demonstrated increased TSPO densities compared with the corresponding healthy tissue. The gene discussed is TSPO; the disease is colon carcinoma.
