Abstract 100P
Background
Colon cancer (CC) is one of the most common malignancies in the world. In this study, we investigated the involvement of a mitosis related chromosome condensation protein NCAPG in tumor progression, and in the prognosis of human CC.
Methods
The patient cohort in this study consisted of 123 CC cases from 2009 to 2013, documenting pathologic and clinical factors, as well as clinical outcomes. Immunohistochemistry and immunoblotting were employed to examine the NCAPG expression in 123 pairs of normal and CC tissues and 7 colon cells. Based on the expression of NCAPG, one CC cell with high NCAPG level was chosen for knockdown of NCAPG expression. The effect of NCAPG knockdown on the growth, migration and invasion of NCAPG-manipulated CC cells was examined.
Results
NCAPG protein overexpression was observed in 88 patients and was significantly correlated with depth of invasion, distant metastasis, staging, and poor disease-free and overall survival. Multivariate Cox regression analysis showed that NCAPG overexpression is an indenpendent prognostic marker for CC. Furthermore, NCAPG expression was elevated in several CC cells. In vitro experiments indicated that NCAPG knockdown inhibited CC cell growth, migration and invasion.
Conclusions
This study suggests that overexpression of NCAPG can be a useful marker for predicting the outcome of CC patients and that NCAPG targeting can represent a potential modality for treating CC.
