NCAPD2 and colon adenocarcinoma: An association between NCAPD2 and NCAPD3 was not observed in pCEP4 transfected RPE-1 cells (Figure 6B), but a detectable NCAPD2/NCAPD3 association was observed in pJM101/L1.3 transfected RPE-1 cells (Figure 6C, D), suggesting that SCC formation can occur in primary cells and may also be dependent on L1 expression, as observed in HT-29 colon adenocarcinoma cells.
