[Expression of oncogenes in transplantable tumors and rodent cell lines].

The expression of 8 oncogenes in transplanted rodent tumours and cell lines was tested. In 6 cases the synthesis of myc-, fos-, ras-oncogene RNA was observed. The transcription of these oncogenes was observed nonspecifically in tumours of different histological types. No difference in the set of the oncogenes expressed and the size of their transcripts was noticed between transplanted tumours and the cell lines obtained from them. The expression of myb-, sis-, Blym-, erb-B- and abl-was not observed in tested cells.

Oncogene expression in human tumors.

The expression of 9 oncogenes in primary tumors and in human tumors passaged in nude mice was tested: a total of 28 tumor types was analyzed. Oncogenes src, fps, and mos were not expressed in any of the tumors tested but oncogene myc was transcribed in most of the tumors and myc was over-expressed in 3 tumors passaged in nude mice (Ewing sarcoma, large intestine carcinoma and kidney carcinoma) and in primary fibrous histiocytoma. Enhanced transcription of ras and fos genes was observed nonspecifically in different tumors. Oncogene sis was activated specifically in metastases of different tumors in lymph nodes.

[Molecular biology criteria for functioning of the genome of Rous sarcoma virus in transformed rat XC cells].

Integration, transcription and translation of Rous sarcoma virus (RSV) genome was analyzed in transformed rat fibrosarcoma XC cells (non-virus producing). About ten copies of RSV genome were integrated into the host cell genome. Different types of viral RNA were identified in the cytoplasmic fraction whose sedimentation values were nearly the same as for RSV-specific RNA in virus-producing chicken cells. These RNA were translated in polysomes and directed synthesis of gag, env and src proteins. In comparison to chicken cells in transformed XC cells the cleavage of gag precursor Pr 76gag could not be observed.
