In HNC tumor cells, loss of PTENP1 (phosphatase and tensin homolog pseudogene 1) pseudogene transcript modulated malignant behavior and worst survival of HNC patients, leading to tumor cell proliferation, colony formation, and migration, possibly by interacting with its parental gene PTEN (phosphatase and tensin homolog) [25]. Here, PTENP1 is linked to neoplasm.
