The expression levels of signal transducer and activator of transcription 3 (STAT3) along with the pathological stage in cancer. (A) The mRNA expression levels of STAT3 in different cancer types were explored by TIMER. (B) The correlation between the expression of STAT3 and the pathological stage in bladder urothelial carcinoma (BLCA), colon adenocarcinoma (COAD), kidney chromophobe (KICH), kidney renal clear cell carcinoma (KIRC), lung adenocarcinoma (LUAD), and lung squamous cell carcinoma (LUSC) was explored by UALCAN database. The first layer asterisk above the error bar represents a comparison to the normal group, and the secondary layers asterisk above a line represents the comparison between corresponding groups that were covered by the line. * p < 0.05, ** p < 0.01, *** p < 0.001.
