We found that in several works of this database (Okayama et al., 2012; Bhattacharjee et al., 2001; Hou et al., 2010; Landi et al., 2008; Selamat et al., 2012; Talbot et al., 2005; Su et al., 2007; Stearman et al., 2005), CXCL13 in tumor samples was elevated compared with their paired normal lung tissues or other normal controls (Figure 1H). Here, CXCL13 is linked to neoplasm.
