Correlation between post-replication repair and metastatic potential in B16 mouse melanoma cell lines.
The rate of postreplication repair of the B16-F1 and the B16-F10 variant clones was compared to the parent B16CL4 mouse melanoma cells in an attempt to correlate the postreplication repair efficiency with the metastatic potential of these melanoma cells. The rate of postreplication repair of the B16-F10 subline was 47% higher than that of the parent B16CL4 mouse melanoma cells and 20% higher than that of the B16-F1 cells. This higher rate of postreplication repair in the B16-F10 cells correlates with its higher metastatic potential. It was also of interest to notice that the rate of postreplication repair of the B16-F1 and the B16-F10 cells are comparable to their rate of replicon joining in non-irradiated cells, in contrast to the parent B16CL4 cells whose rate of post-replication repair was significantly lower than its rate of replicon joining.
