Overall, HERV-K env and pol gene mean transcription levels in cancer tissues and normal tissues were similar (HERV-K env: normal tissue 1.19 ± 0.58, and tumor tissue: 1.19 ± 0.71; HERV-K pol: normal tissue 2.72 ± 4.42, and tumor tissue 2.23 ± 1.81) (HERV-K env p = 0.083 and HERV-K pol p = 0.800). The gene discussed is ERVW-1; the disease is cancer.
