Comparable with other cytokines already described, IL-8 has been described in other GM studies of pulmonary phenotypic expression such as asthma [139], COPD [137], wheezing [140], and bronchiolitis [141], and also in other phenotypes such as lupus, breast cancer, ovarian, and prostate disease [66]. This evidence concerns the gene CXCL8 and breast carcinoma.
