Polyploidization of G2M phase cells separated from aerobically and anaerobically grown Ehrlich ascites tumor cells

Polyploidization of G2M phase cells separated from aerobically and anaerobically grown Ehrlich ascites tumor cells

C Kroll et al. J Cancer Res Clin Oncol. 1987.

Abstract

G2-enriched fractions of Ehrlich ascites tumor cells (up to 80%-85% G2 cells) separated from anaerobically and aerobically cultured asynchronous populations by centrifugal elutriation revealed the same growth characteristics after recultivation under standard conditions: a significant proportion of cells with increased DNA (DNA content greater than 4C) emerged. Interruption of DNA synthesis by deprivation of oxygen may account for polyploidization (over-replication) of DNA but other mechanisms must be taken into consideration.
