The tumor suppressor gene CIS and the oncogene c-Myc are the target genes of STAT5, α-Br-TMC down-regulated c-Myc and up-regulated CIS in Ba/F3-1*6 cells, therefore, α-Br-TMC is expected to be used in the treatment and intervention of STAT5 related malignant tumors in the future (Pinz et al., 2014). Here, STAT5A is linked to in situ carcinoma.
