Consistent with ADPL experiments on these cell lines alone (Fig. 4a), NCEH1 activity was almost exclusively present in the SKOV3 cancer cells, quantified as an ~22-fold increase in NCEH1 activity relative to immune cells (Fig. 6c, d), whereas much less signal was present in both OVCAR3 and its co-cultured immune cells, likewise quantified as a ~6-fold increase relative to immune cells (Fig. 6e, f). Here, NCEH1 is linked to cancer.
