CYFIP1 and thyroid gland follicular carcinoma: Since a positive correlation was seen in thyroid tissues, the correlation analysis was also performed in follicular thyroid carcinoma cell lines that ectopically expressed ABI3. An increase in the levels of the CYFIP1 and WAVE2 proteins in WRO cells expressing ABI3 as compared to control that do not express ABI3 (empty vector) (p<0.05).
