Abstract

The interaction between cancer cells and stromal components contributes to cancer invasion and metastasis in pancreatic ductal adenocarcinoma (PDAC). The present study investigated the role of the correlation between annexin II (ANX2) and stromal tenascin C (TNC) with the progression of PDAC. The functions of the expression ANX2 and TNC were assessed in in vitro experiments using mouse and human PDAC cells, and the clinical effect was analyzed using immunohistochemistry with surgically resected PDAC tissues. The effects on epithelial to mesenchymal transition (EMT), invasion, putative cancer stemness, and anoikis resistance were examined in vitro using murine precancerous pancreatic intraepithelial neoplasia (PanIN) cells and murine and human invasive PDAC cells with ANX2 knockdown using specific small interfering RNA (siRNA)s and recombinant TNC (rTNC). ANX2 was expressed at a high level in primary PanIN cells and invasive PDAC cells, compared with the levels in liver metastatic PDAC cells. In the ANX2‑knockdown cells, there were fewer cells with a morphological mesenchymal appearance in three‑dimensional culture and invasion was reduced compared with that in the control cells. Morphological change into the mesenchymal phenotype and invasion were enhanced by rTNC treatment in the control PDAC cells but not in the ANX2‑knockdown cells. Pancreatosphere formation assays showed that ANX2 and TNC facilitated the maintenance of stem‑like characters in PDAC cells. Furthermore, anoikis assays indicated that the interaction of ANX2‑TNC contributed to anoikis resistance in PDAC cells. In the immunohistochemistry analyses, the group with a high expression of ANX2 and high stromal TNC was significantly correlated with distant metastasis, and was associated with hematogenous/peritoneal recurrence and poor outcomes following surgery in resected human primary PDAC tissues. In conclusion, the results demonstrated that ANX2 and stromal TNC regulated invasion in addition to stemness and anoikis resistance, which are crucial for metastasis in the progression of PDAC. These results indicate the potential of the ANX2‑TNC axis as a therapeutic target for PDAC metastasis.
