MALAT1 and acute kidney injury: While we did detect increased expression levels of Malat1 in ischemic kidney biopsies and plasma of patients with AKI, ischemic mouse kidneys and sorted endothelial cells and tubular epithelial cells ex vivo, we were unable to report an overt phenotype of Malat1 knockout mice in contrast to previous studies investigating the in vivo role of Malat1 in other disease settings.
