CCL4 and gastric cancer: We therefore screened for a panel of chemokines in sera of PpardTG mice and sex- and age-matched WT littermates at ages of 10 weeks (before GC development), 25 weeks (at early stages of GC, i.e., hyperplasia and low-grade dysplasia) and 55 weeks (at late stages of GC, i.e., high-grade dysplasia and adenocarcinoma) [8] using the LEGENDplex Mouse Proinflammatory Chemokine Panel, which simultaneously quantifies 13 major inflammatory chemokines (Ccl2, Ccl3, Ccl4, Ccl5, Ccl11, Ccl17, Ccl20, Ccl22, Cxcl1, Cxcl5, Cxcl9, Cxcl10, and Cxcl13).
