ITGA2, ITGA3, ITGA10, ITGB4, and ITGB6 were more highly expressed in epithelial cells (tumor, atypical ductal, acinar, ductal, or endocrine cells), and ITGA2, ITGA3, and ITGB4 were highly expressed in malignant cells (tumor or atypical ductal cells) (Fig. 1B). This evidence concerns the gene ITGA10 and neoplasm.
