To study the possible involvement of mouse mammary tumour virus (MMTV) related agent in human cancer we analysed 300 samples of human sera for the presence of antibodies to MMTV structural proteins. All sera were tested by immunoblotting to achieve high specificity. Out of 300 sera, 22 reacted with transframe protein p30, 16 with the ribonucleoprotein p14,(More)
Very small amounts of retrovirus-like particles were obtained from tissue culture fluids of various human cell lines. The particles were found in almost all cultures of rapidly growing human cells (embryo fibroblasts, various types of leukemias, melanoma, urinary bladder, lung and mammary carcinomas).
