4 Alterations of the oncogenic properties of tumor cell lines by modulating oncogene expression. Example of v-src transformed chicken cell lines Abstract v-Src protein tyrosine kinase is the product of the transforming gene transduced by avian Rous sarcoma virus. In contrast to proto-oncogene c-src, v-src lacks the negative-regulatory C-terminal domain and consequently shows a higher level of activity and transforming ability. In addition, v-Src contains point mutations throughout its coding region that probably contribute to the high level of intrinsic kinase activity. Long terminal repeats (LTR) comprise strong promoter-enhancer sequences and ensure efficient expression of the v-src gene. v-Src protein has a strong transforming potential in vitro and induces tumor development and growth in vivo. Moreover, it is implicated in metastatic formation. In several cancer types the elevated c-Src kinase activity caused pleiotropic cellular responses inducing transformation and metastasis. The aim of this diploma work was to reveal the role of v-Src in mediating tumor and metastatic progression in chicken cell lines PR9692 and PR9692-E9. Despite the low propensity of the chicken cells to immortalization, comparatively high immoratlization efficiency was observed in cells from ex vivo tumours growing progressively...
