Gautam et al. (32) and Gautam & Deodhar (33) reported that the tumoricidal effect against fibrosarcoma and colon carcinoma that CRP/liposomes had on peritoneal exudate cells was like the effect seen with muramyl-tripeptide (MTP)/liposomes except that the CRP/liposome effect required an intact complement system in experimental animals. This evidence concerns the gene CRP and colon carcinoma.
