STAT4 and breast carcinoma: Additionally, employing the Human Protein Atlas database, protein expression levels of STAT1, STAT4, and STAT5A in normal and breast cancer tissues, as well as in normal and lung cancer tissues were displayed in Supplementary Figures S1A, S1B, and the protein expression levels of STAT6 in normal and lung cancer tissues, along with in normal and urothelial cancer tissues were demonstrated in Supplementary Figure S1C, which further validated the results above.
