In HNC tumor cells and cell lines (FaDu, Cal-27, SCC4, and SCC9), FKBP9P1 (FKBP prolyl isomerase 9 pseudogene 1) pseudogene transcript abundance was found to correlate with advanced tumor stage and poor prognosis of patients by enhancing tumor cell proliferation, migration, and invasion, possibly by interacting with the PI3K/AKT signaling pathway [26]. The gene discussed is AKT1; the disease is neoplasm.
