title: All three human ras genes are expressed in a wide range of tissues.
abstract: We examined the expression of the ras gene family (Ha-ras, Ki-ras, N-ras) in human fetal tissues (14 week) and in several human tumor cell lines. Dot blot hybridization showed that the three ras genes were expressed in all of the samples analysed, with a range of expression between 10 and 180 molecules/cell. There was no correlation between levels of expression of ras genes and the type of ras gene activated in different tumor types.
