Abstract:
Several studies have processed conceivable evidence for the vital role of Signal Transducer and Activator of Transcription 3 (STAT3) in cancer transformation and carcinogenesis. Therefore, one of the important factors in formation of cancer is STAT3 and for design of novel anticancer drugs is a suitable target. On the other hand, apoptosis pathway has a critical role in the cancers pathogenesis. Generally, increasing developments have been existed to expression, production, phosphorylation or activation of STAT3 in the effective or responsible cells of most of the cancers. In return, apoptosis process in this cells have been suffered inhibition, decrease in expression, produce or activation in some related factors which lead to debilitation or inhibition of the process. Further understanding of the STAT3 related signaling and apoptosis pathway can lead to the invention of novel approaches for therapies in unstudied disease. In this manuscript, review and highlight recent knowledge of the STAT3 pathway and its connection with apoptosis process in cancers and discuss STAT3-targeting agents to therapeutic developments.

However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
