Effects of targeted CD97 immune epitopes small interference RNA on cellular biological behaviors in MDA-MB231 malignant breast cancer cell line.


ABSTRACT: Two CD97 immune epitopes, CD97EGF (epidermal growth factor domain) and CD97Stalk (stalk domain), have different distribution patterns in malignant epidermal tumors. However, little is known about the effect of CD97EGF and CD97Stalk immune epitopes in breast cancer metastasis. To explore the effects on cell proliferation, infiltration, apoptosis, and the cell cycle, we used small interfering RNA (siRNA) against CD97EGF and CD97Stalk immune epitopes to knock down CD97 in MDA-MB231 breast cancer cells. Compared with controls, CD97 knockdown caused decreased cell growth, proliferation, migration, infiltration, and altered distribution of the percentage of cells in G0/G1 and S phase. We suggest that the potential mechanism of CD97EGF and CD97Stalk immune epitopes on the biological behaviors of MDA-MB231 breast cancer cells may be related to the altered number of N-terminal glycosylation sites, which influence the stability and signaling intensity of CD97 heterodimers.
