Knockdown of FASTKD4 lung cancer cells led to the inhibition of cell proliferation, migration, and invasion highlighting its role in tumour growth in lung cancer [23].In the case of pancreatic adenocarcinoma, FASTK and FASTKD2 had also been involved in proliferation, invasion, and migration and hence poor prognosis [24,25]. Here, FASTKD2 is linked to neoplasm.
