Figure 2. Plasminogen activator inhibitor 1 (PAI-1) protein is reduced in muscle of longitudinally sampled overweight men with characteristics of metabolic syndrome.

A, normalized (to myosin) expression levels of PAI-1 in skeletal muscle after exercise training and detraining as shown by Western blot quantification. B, representative PAI-1 Western blot with the molecular weight marker shown on the left. Data are longitudinal samples from 3 subjects ±s.e.m.; P value was determined using Student's t test.
