Overexpression of the proto‐oncogene/translation factor 4E in breast‐carcinoma cell lines

The expression of the proto‐oncogene, translation factor elF‐4E, was examined in breast‐cell lines: 5 carcinomas and 2 normal. At the protein level, elF‐4E was 10 times higher in the carcinoma lines than in normal cells, which is comparable to the level found in breast‐cancer biopsies. The elevation...
