As hIL6 activates the Janus kinase‐signal transducer and activator of transcription (JAK‐STAT) pathway (Chen et al., 2000; Yu et al., 2014), we examined the degree of phosphorylation of the signal transducer and activator of transcription 3 (STAT3) in an androgen‐sensitive human prostate adenocarcinoma (LNCaP) cell line (Chen et al., 2000). The gene discussed is STAT3; the disease is prostate adenocarcinoma.
