doi: 10.3892/ol.2018.8510
Figure Lengend Snippet: Effects of CXCL13 on the expression levels of three key proteins of the CXCR5/ERK pathway (CXCL13, CXCR5 and p-ERK) was analyzed in the Control, Model and Inhibitor groups. (A) Western blot analysis demonstrating that CXCL13, CXCR5 and p-ERK protein levels increased, with an increased p-ERK/ERK ratio, in the Model and Inhibitor groups compared with those in the Control group. The protein levels of CXCL13, CXCR5 and p-ERK decreased and the ratio of p-ERK/ERK decreased with CXCL13 inhibition. (B) Quantification of the western blot allowed for statistical analysis of the relative levels of proteins (normalized to β-actin). *P<0.05 vs. Control group; #P<0.05 vs. Model group. CXCL13, C-X-C Motif Chemokine Ligand 13; CXCR5, C-X-C motif chemokine receptor 5; ERK, extracellular-regulated protein kinases; p-ERK, phosphorylated-ERK.
