This finding matches results of an irradiation‐induced lung fibrosis study,37 although differing from another showing that FG‐3019 has no effect on skeletal muscle levels of CCN2.39 CCN2 levels and signaling responses are known to be context dependent, vary with cell type and matrix in which it is functioning, and environmental stimulants.40 The gene discussed is CCN2; the disease is pulmonary fibrosis.
