ANXA2 and carcinoma: H&E staining showed that the histopathology of tumors formed by the LncCCAT1-overexpressing MCF-7 cells exhibited morphologic characteristics of poorly differentiated carcinoma and increased cell mitosis, whereas miR-204/211, miR-148a/152 and sh-ANXA2 attenuated these effects and showed morphological characteristics of highly differentiated carcinoma with low malignancy (Figure 7E).
