The cellular origin of chemically induced tumours.
Tumours were induced by chemical carcinogens in chimaeric mice made by the amalgamation of two embryos each producing a different electrophoretic variant of the enzyme glucose phosphate isomerase. Although, in these chimaeras, the smallest samples of normal tissue that could be analysed almost invariably contained both isoenzymes, almost all the tumours contained only one. An analysis of the si...
متن کاملDifferentiation Between the Embryonic and Tumour Specific Antigens on Chemically Induced Rat Tumours
The tumour specific antigens and tumour associated embryonic antigens expressed on chemically induced rat hepatomata and sarcomata have been shown to be different by means of blocking antibody studies. Serum from multiparous female rats contained blocking antibody which protected both tumour and embryo cells from the in vitro cytotoxic effect of lymph node cells from multiparous donors. These s...
متن کاملFurther evidence of common antigenic properties in chemically induced sarcomas of mice.
The transplantability of five methylcholanthrene-induced sarcomas of C57BL/6 mice was tested by subcutaneous inoculation of quantitated tumor cell suspensions in variously immunized syngeneic recipients. All five tumors gave evidence of resistance in recipients that were immunized and challenged with the same tumor. There was no evidence of cross-resistance between these tumors when mice were i...
متن کاملGenetic differences in susceptibility to chemically induced myelotoxicity and leukemia.
The Ah locus represents a complex "cluster" of genese controlling the induction of numerous drug-metabolizing enzyme "activities" by polycyclic aromatic compounds. Allelic differences at the Ah locus are reflected in the large differences in inducibility of cytochrome P1-450 and benzo[a]pyrene metabolism in numerous tissues when the mice receive the chemical daily in their diet. This experiment...
