Some of the enriched epithelial genes or cytokine genes have been reported to get involved in cancer development and progression, for example, SERPINB5 in breast cancer (24), CCL3L1 in glioblastoma (25), CXC group in lung cancer (26), MMP28 in gastric cancer (27) and so on. The gene discussed is SERPINB5; the disease is lung carcinoma.
