Steroidogenic acute regulatory (StAR) protein-related lipid transfer (START) domain-containing protein 7 (STARD7) is a phosphatidylcholine-specific (PC-specific) lipid transfer protein that transports PC from the ER to the mitochondria, facilitating mitochondria membrane stabilization and respiration function. The aim of this study was to define the contribution of STARD7 in the regulation of the intestinal epithelial mitochondrial function and susceptibility to colitis. In silico analyses identified significantly reduced expression of\n                    <jats:italic>STARD7<\/jats:italic>\n                    in patients with UC, which was associated with downregulation of metabolic function and a more severe disease phenotype. STARD7 was expressed in intestinal epithelial cells, and STARD7 knockdown resulted in deformed mitochondria and diminished aerobic respiration. Loss of mitochondria function was associated with reduced expression of tight junction proteins and loss of intestinal epithelial barrier integrity that could be recovered by AMPK activation.\n                    <jats:italic>\n                      Stard7\n                      <jats:sup>+\/\u2013<\/jats:sup>\n                    <\/jats:italic>\n                    mice were more susceptible to the development of DSS-induced and\n                    <jats:italic>\n                      Il10\n                      <jats:sup>\u2013\/\u2013<\/jats:sup>\n                    <\/jats:italic>\n                    spontaneous models of colitis.
