SPR and melanoma: Figure 5C illustrates S-phase-specific γH2AX fold-inductions at 1 h post-UV for 1BR and F02-98, compared with 3 normal melanocyte lines (GM22134, GM21807 and GM22141) and 12 melanoma strains, i.e. 3 SPR-proficient (WM1341D, WM35 and WM1366) vs. 9 SPR-deficient (WM3734, WM3211, WM1617, WM983B, WM3248, WM902B, WM1361A, WM278 and WM2664).
