In addition, recent researches suggested that an elevated level of pStat3 displays relations to poor prognosis of many cancers, including lung cancer,8 colorectal cancer9 and lung cancer.10 Stat3’s critical role in tumorigenesis and tumour prognosis emphasizes that novel anti‐cancer drugs capable of regulating Stat3‐mediated signalling events in a negative manner are urgently required. The gene discussed is STAT3; the disease is lung cancer.
