Role of STAT3 in Resistance of Non-small Cell Lung Cancer / 中国肺癌杂志

The inflammatory state of tumor microenvironment play an important role in non-small cell lung cancer (NSCLC) drug resistance. As the key signal pathway connecting inflammation and tumor, activated signal transduction and transcriptional activation factor 3 (STAT3) leads togenetic abnormal expression, gene silencing, genomic instability, etc. in tumor cells, and induces therapeutic resistance. STAT3 has thepotential to be a new target for reversal of resistance. In this review, we summarize the progress of STAT3 in acquired drug resistance of NSCLC, explore the possibility of STAT3 as a new target to reverse drug resistance, and provide basic theories for the new clinical treatment strategy of acquired drug resistance in NSCLC.
