ZEB1 and breast carcinoma: To further define the role of SIX‐1‐LncATB‐miR‐200‐ZEB1 axis in human breast cancer patients and the correlation between SIX‐1, lncATB, miR‐200c‐3p and ZEB1, we measured the relative expression levels of SIX‐1, lncATB, miR‐200c‐3p and ZEB1 in 203 samples, including 20 normal breast tissues and 183 breast cancer tissues.
