It functions as an oncogene by targeting important tumor suppressors, such as CDX1, STAT5A, SOCS2, ICAM1, CASP8, NGFR, NF2, and HGS, and thereby regulates important cancer-related processes, such as cell proliferation, apoptosis, invasion, migration, blood vessel development, and chemoresistance [36]. This evidence concerns the gene STAT5A and cancer.
