We previously identified the NKA (Na\/K-ATPase) \u03b11 subunit as a signal transducer that activates Src-family kinases and promotes oxidative stress and inflammation in various cell types, including adipocytes and macrophages. NaKtide, a peptide inhibitor of NKA signaling, has been shown to reduce systemic oxidative stress and inflammation in vivo. In this study, we investigated the role of adipocyte-specific NKA signaling in atherosclerosis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>METHODS:<\/jats:title>\n                    <jats:p>\n                      Adipocyte-specific NaKtide was delivered to\n                      <jats:italic toggle=\"yes\">Apoe<\/jats:italic>\n                      <jats:sup>\u2212\/\u2212<\/jats:sup>\n                      mice using a lentiviral vector under the adiponectin promoter. The mice were then fed a Western diet for 12 weeks to induce atherosclerosis and then assessed for atherosclerotic plaque burden in the aortic arch and at the level of the aortic sinus.
