Altered expression of proto-oncogenes in human lymphoid cells immortalized by transfection with extrachromosomal DNA of mouse L cells.

Anticancer research - 1 Jan 2000

Abken H, Bützler C, Willecke K

Abstract excerpt

Human lymphocytes were induced to proliferate continuously in vitro by transfection with extrachromosomal DNA from mouse L929 cytoplasts. The immortalized cells contain 2- to 5-fold increased mRNA levels of only 3 (c-Ha-ras-1, c-Ki-ras, c-myc) out of 18 proto-oncogenes tested compared to quiescent lymphocytes. Furthermore, the immortalized cells contain decreased amounts of c-fos mRNA, 2- to 20-fold decreased...
