Figure 2. Silencing CXCR5 attenuates migration, invasion and PNI in SACC cells. (A) Immunofluorescence and qRT-PCR analysis showed that CXCR5 expression was dramatically inhibited by siRNA treatment. (B–D) CXCR5 silence with siRNA or CXCR5 blockade with anti-CXCR5 antibody impeded migration, invasion and PNI of SACC-LM cells, (Bar: 100 μm). (E) Immunofluorescence and qRT-PCR analysis showed that CXCR5 level was significantly increased by CXCR5-overexpressing plasmid. (F–H) CXCR5 overexpression enhanced migration, invasion and PNI capacity of SACC-LM cells, (Bar: 100 μm) (*p < 0.05, **p < 0.01, ***p < 0.001).
