IFT20 and breast cancer: Consistent with our results, Yang et al. reported that the level of IFT20 protein was negatively correlated with the malignancy of breast cancer cells, in which deletion of IFT20 promoted epithelial-mesenchymal transitions (EMT) and enhanced the migration of breast cancer cells by decreasing F-actin associated protein Transgelin-2 (TAGLN2) expression [25].
