In clinical microarray results, increased vimentin mRNA after chemotherapy correlated with poor prognosis in breast cancer patients.
Vimentin knockdown in MDA-MB 231 cells reduced cell proliferation, impaired wound healing, caused loss of directional migration, and increased large membrane extension.
Vimentin overexpression in MCF7 cells increased cell stiffness, elevated cell motility and directional migration, reoriented microtubule polarity, and increased EMT phenotypes.
The EMT-related transcription factor Slug was mediated by vimentin.
The increased EMT phenotypes observed with vimentin overexpression in MCF7 cells were associated with increased β1-integrin and loss of E-cadherin.
Vimentin depletion reorganized cytoskeletons and reduced focal adhesions, leading to impaired mechanical strength through reduced cell stiffness and contractile force.
Vimentin serves as a regulator that maintains intracellular mechanical homeostasis in EMT cancer cells by mediating cytoskeleton architecture and the balance of cell force generation.
