Analysis of changes in VEGFR2 expression in pooled tumor lysates produced heterogeneous results, with reduced total or p-Tyr951 VEGFR2 levels in GC17-0409 and GC28-1107 tumors, respectively, and no apparent changes in p-Tyr951 VEGFR2 levels in GC09-0109 tumors (Fig. 4). Here, KDR is linked to neoplasm.
