It has been reported that in breast cancer miR203 targets SOCS3 (suppressor of cytokine signaling 3), a negative regulator of fetal liver hematopoiesis and placental development, and ABL1 (Abelson murine leukemia viral oncogene homolog 1), which implicates in processes of cell differentiation, cell division, cell adhesion, and stress response [26,27]. The gene discussed is ABL1; the disease is breast cancer.
