TWEAK increases histone crotonylation in kidney tubular cells. TWEAK increases histone crotonylation in kidney tubular cells. Western blotting of histone crotonylation (anti-Kcr) in cultured murine proximal tubular cells stimulated with 100 ng/ml TWEAK. Data from five independent experiments is expressed as the mean±s.e.m. Results are expressed as percentage change of crotonylated histones over control.*P<0.05 vs control (Student's t-test). Olga Ruiz-Andres et al. Dis. Model. Mech. 2016;9:633-645 © 2016.
