Our results about immunity/inflammatory-related metagenes showed that PLK1 mRNA levels were negatively correlated with enrichment scores of Interferon and lymphocyte-specific kinase (LCK) in glioblastoma multiforme (GBM) (Supplementary Figure 9), which implied that Interferon and LCK might be protective factors, different from PLK1. The gene discussed is LCK; the disease is glioblastoma.
