Fig. 4From: Evaluation of α-tubulin, detyrosinated α-tubulin, and vimentin in CTCs: identification of the interaction between CTCs and blood cells through cytoskeletal elementsProgression-free survival (PFS) of patients with metastatic breast cancer. (I) Sequential samples from a patient with breast cancer. Quantification of α-tubulin (TUB) intensity (a), detyrosinated α-tubulin (GLU) intensity (b), vimentin (VIM) intensity (c), cytokeratin (CK)/TUB ratio (d), CK/GLU ratio (e), and CK/VIM ratio (f). (II) (a) PFS in patients with CK+GLU+VIM+-expressing CTCs (p = 0.004). (b) PFS in patients with CK+GLU−VIM+-expressing CTCs (p = 0.007)Back to article page
