Association of viral oncogene-induced changes in gap junctional intercellular communication and morphological transformation in BALB/c3T3 cells
1993
In order to study the relationship between altered gap junctional intercellular communication (GJIC) and induction of cell transformation by oncogenes, we transfected six viral oncogenes into BALB/c3T3 A31-1-1 cells. BALB/c3T3 cells with v-src, v-ras or polyoma middle T (PyMT) genes grew in soft agar and formed distinct transformed foci in the absence or presence of a vast excess of non-transfected cells. On the other hand, those with v-myc, v-fos or polyoma large T (PyLT) genes expressed less distinctly transformed phenotypes (less transformed morphology, higher saturation density than non-transfected counterparts and less growth in soft agar, and did not form distinct foci in coculture with non-tranformed cells
