JAK2 inhibitor AZD1480 inhibits JAK2 activation, leading to the inhibition of the JAK/STAT (signal transducer and activator of transcription) signaling including activation of STAT3. This may lead to induction of tumor cell apoptosis and a decrease in cellular proliferation. JAK2, often upregulated or mutated in a variety of cancer cells, mediates STAT3 activation and plays a key role in tumor cell proliferation and survival."}]
