Additionally, CX3CL1, a gene that encodes a context-dependent chemokine, showed a strong positive correlation with the co-expression of PEBP1/STK11 in KIRC, KIRP, CESC, LUAD, and GBM, while CCL16 exhibited a positive correlation only in LIHC and THCA. The gene discussed is CX3CL1; the disease is glioblastoma.
