  • Title: [The sensitivity to growth factors of NIH 3T3 cells transformed by the v-myc oncogene].
    Author: Pospelova TV, Blagosklonnyĭ MV, Zaritskiĭ AIu.
    Journal: Tsitologiia; 1990; 32(4):358-63. PubMed ID: 2238109.
    Abstract:
    Transformation of NIH 3T3 cells, induced by v-myc oncogene, activates a proliferative potential of the cells cultivated in the serum-free medium, and reduces the ratio of 3H-Tdr incorporation into the cells grown in the presence of 10% fetal serum in comparison to those grown in the serum-free medium. The v-myc transformed cells (NIH 3T3-v-myc) as well as the untransformed ones are very responsive to insulin. On the other hand, the epidermal growth factor, able to stimulate proliferation of NIH 3T3 cells, exert no effects on the NIH 3T3-v-myc cells. The NIH 3T3-v-myc cells cultivated in the medium, containing 2.5% human plasma enriched with thrombocytes, have the same proliferative characteristics as cells grown in the thrombocyte-free plasma. It is concluded that transformation of NIH 3T3 cells induced by v-myc oncogene may reduce a requirement for thrombocyte-released growth factors and EGF but not for insulin.
