The role of STAT6 in cancer has recently been studied; there are studies in colorectal cancer, prostate cancer, glioblastoma, gastric cancer, and breast cancer that indicate that STAT6 may have an important role in the growth, aggressiveness, resistance to apoptosis, epithelial to mesenchymal transition, and metastasis of cancer cells [145,146,147,148,149].
