In contrast to lung metastasis, when we examined tumor formation by injecting clone-1-TUM or clone-1-TUM (SATB1-shRNA) into the mammary fat pads of nude mice, we found virtually no difference in the ability to form tumors by these two cell lines (Fig. 3G), except for a slight delay in onset of tumor growth by the latter during the first 2 weeks (Fig. S2B). Here, SATB1 is linked to neoplasm.
