Activation of STAT3 in gastric cancer development

Abstract

The transcription factor STAT3 important for regulating factors that involve in the modulation of gene expression. The factors such as growth factors and cytokines regulate homeostasis of both epithelial and stromal cells. Deregulation of STAT3 activation is important in the initiation of transformation of various cancers that are epithelial in origin. This chapter mainly focuses on STAT3 activation in gastric cancer and its progression with the activation of cytokines; it also discusses how STAT3 associated with progression of gastric cancer. The studies have shown the association of deregulated JAK/STAT in the development of solid cancers especially in gastric cancer. Therapeutic use of STAT3 may prevent the development of gastric cancer. Inhibitors of STAT3 are emerging as a potent drug in treatment options. STAT3 inhibitors are under evaluation in various clinical trials, showing promising results for the treatment.
