SATB1 and cancer: In some cases, cell lines originated from metastases showed considerably higher SATB1 expression than the corresponding cell line from the primary cancer (UT-SCC-74A/B, UT-SCC-42A/B) whereas no difference (UT-SCC-16A/B) or the opposite (UT-SCC-60A/B) was seen in other cases (Fig. 1B).
