NCAPD3 and cancer: To examine the function of NCAPD3 in gastric cancer, first, we measured NCAPD3 expression in four cancer-derived GC cell lines (AGS, BGC823, MGC803, and SGC7901) by RT-qPCR and found that the expressions of NCAPD3 mRNA in these four gastric cancer were all high-abundence (Supplementary Material 1).
