A number of incubation media which have been used in studies of the metabolism of Ehrlich ascites carcinoma (EAC) cells in vitro have been examined with respect to their abilities to support the incorporation of radioactive precursors into nucleotides and nucleic acids, and to maintain the structural integrity and tumor-inducing abilities of EAC cells. Cells incubated in the chemically-defined "Fischer's medium for leukemic cells of mice" were able to produce lethal tumors in mice after more than 16 h of incubation, maintained their structural integrity on prolonged incubation, and catalyzed high rates of incorporation of exogenously added substrates into nucleotides, RNA, and DNA. However, cells incubated in balanced salts solutions supplemented with glucose had these characteristics: (a) were unable to produce lethal tumors after 4 h of incubation, (b) released large amounts of nucleotide, nucleic acid, and protein material into the medium after less than 2 h of incubation, and (c) catalyzed the incorporation of radioactive precursors into nucleotides and RNA at much lower rates than did cells incubated in Fischer's medium, and were virtually unable to catalyze the incorporation of adenine-14C into DNA.

Mouse Leukaemia

With the use of the isoschizomeric restriction endonucleases HpaII and MspI, we found that mouse tumour ornithine decarboxylase (ODC; EC 4.1.1.17) genes are extensively methylated. ODC genes in L1210 mouse leukaemia cells were apparently more methylated than in Ehrlich ascites carcinoma, as revealed by the use of HpaII endonuclease, yet the digestion of genomic DNA isolated from these two murine tumour cell lines with MspI, which cleaves at a CCGG sequence, also with internally methylated cytosine, resulted in an apparently identical restriction pattern. It is possible that the amplification of ODC genes in Ehrlich ascites-carcinoma cells in response to 2-difluoromethylornithine (DFMO) was associated with hypomethylation, or that less-methylated genes were amplified. A human myeloma (Sultan) cell line only revealed three separate hybridization signals when cleaved with HpaII. One of these signals was amplified under the pressure of DFMO. When cleaved with MspI, these three HpaII fragments disappeared and were replaced by a double signal of 2.3-2.4 kilobase-pairs (kbp) in size. The amplified ODC sequences in the Sultan myeloma cell line apparently originated from chromosome 2, as indicated by a unique hybridization signal in a 5.8 kbp HindIII fragment specific for the human ODC locus on chromosome 2. A comparison of different human cells, the Sultan myeloma, a lymphocytic B-cell leukaemia (Ball), normal mononuclear leucocytes and leucocytes obtained from leukaemia patients, revealed interesting differences in the methylation of ODC genes. The use of two restriction endonucleases (HpaII and CfoI), the cleavage site for both of which contains a CG sequence and which only cleave when cytosine is unmethylated, indicated that ODC genes in the lymphocytic leukaemia cells were much less methylated than those in the normal leucocytes or in the Sultan cells.
