VIM and chronic obstructive pulmonary disease: To further evaluate the association between vimentin processing/PTMs and lung pathology we measured MMP-degraded citrullinated vimentin (VICM) and the non-citrullinated counterpart (VIM) in serum from two independent cohorts of patients with non-small cell lung cancer (NSCLC), a cohort of patients with chronic obstructive pulmonary disease (COPD) and healthy controls.
