Although it was not sufficient to detect all annotated genes due to the lack of the number of reads that mapped to human genes in the metastatic tumor samples (1 to 5 million reads), we did find that the expressions of human CXCR4, MIAT, PLLP, TNFSF4, VCAM1, SLC8A2, and SLC7A11 were upregulated in the metastasized cancer cells both in the brain and in the bone marrow. The gene discussed is PLLP; the disease is cancer.
