Relationship between OSBPL3 protein expressions and differentiations. a There were significant difference in the expression of OSBPL3 between tumor and normal tissues (****P < 0.0001); the expression of OSBPL3 in tumor tissues was negatively correlated with the degree of tumor differentiation from poor to well. With the decrease of differentiation degree, the scores of OSBPL3 protein expressions tend to be higher, and there were a statistical significance in differentiation (***P < 0.001). b Representative results of OSBPL3 by IHC. It was weakly expressed in cytoplasm and cell nucleus of normal intestinal epithelium and well differentiated tumor tissues; it was highly expressed in cytoplasm of poorly differentiated tumor tissues (Magnification × 200, × 400)
