TRIM72 and idiopathic pulmonary fibrosis: Nevertheless, different from the broad subcellular localization of TRIM72 in normal lung ATII cells where it is mostly concentrated in the lung, TRIM72 in ATII cells from IPF lung concentrates in the nucleus, raising the question whether the change in TRIM72 subcellular localization is a consequence of repeated lung injury and casting doubts on whether the upregulated TRIM72 in IPF lungs retains its physiological protective function.
