Normal rat kidney proximal tubular cells (NRK-52E) are maintained in six-well 100 or 150-mm, or 150-mm plates in a humidified incubator gassed with 5% CO2 and 95% air at 37°C in DMEM containing 5% fetal calf serum (FCS). Cells are grown to 60% confluence and divided into four treatment groups: 1) untreated (Untx), 2) CS, 3) CS+Mitoquinone (MitoQ), and 4) CS+DecylTPP. Untreated cells remained at 37°C in DMEM containing 5% FCS (group 1). CS is initiated by washing cells with cold PBS twice and storing them in UW/Viaspan solution alone (4 h at 4°C) (group 2), CS+Mitoquinone (1 μM) (group 3), or CS+DecylTPP (1 μM) (group 4). In separate experiments, cells are exposed to CS plus RW by replacing UW solution alone or UW solution containing Mitoquinone or DecylTPP with DMEM containing 5% FCS overnight (18 h at 37°C).
MiceMale CD1 mice (30-35 g) or C57BL/6J mice (20-25 g) are used. Seven intraperitoneal injections of a supramaximal dose (50 μg/kg) of Caerulein, a CCK-8 analogue, are given on an hourly basis to induce hyperstimulation acute pancreatitis (CER-AP). Control mice receive equal volumes of PBS injection. In the Mitoquinone treatment groups, Mitoquinone at 10 mg/kg (dose 1) or 25 mg/kg (dose 2) is given at the first and third injections of Caerulein. Similarly, dTPP at 9.6 mg/kg (dose 1) or 24 mg/kg (dose 2) is given for the dTPP treatment group. Mitoquinone and dTPP are at the same molar concentration at doses 1 and 2. Mice are sacrificed at 12 h after the first Caerulein injection to collect samples. Bile acid-induced AP is achieved by retrograde infusion of TLCS into the pancreatic duct (TLCS-AP). After induction of anesthesia, TLCS applied using a mini infusion pump at a speed of 5 μL/min for 10 minutes. Successful infusion of TLCS into pancreas is demonstrated by a diffuse light blue colour (methylene blue) appearing in the pancreatic head. Control mice receive sham surgery without TLCS infusion. In the treatment groups, Mitoquinone (10 mg/kg) or dTPP (9.6 mg/kg) is given at 1 h and 3 h after TLCS infusion. Mice are sacrificed at 24 h after the TLCS infusion or sham surgery.

Mitoquinone is a mitochondria-targeted antioxidant designed to accumulate within mitochondria in vivo in order to protect against oxidative damage.
Mitoquinone (MitoQ) is a mitochondria-targeted antioxidant.The optimal doses for Mitoquinone (MitoQ) and DecylTPP treatment are selected from dose-response experiments during 4-h cold storage (CS). The potential protective benefits of Mitoquinone treatment against CS injury are tested initially using MitoSOX Red, a mitochondrial-targeted fluorescent dye that measures mitochondrial superoxide generation. Normal rat kidney (NRK) cells exposed to CS result in a ~2-fold increase in fluorescence due to mitochondrial superoxide compared with untreated cells. Mitoquinone offers significant protection against CS-induced mitochondrial superoxide generation; whereas the control compound DecylTPP does not offer any protection. Mitoquinone treatment markedly decreases mitochondrial superoxide generation, whereas kidneys treated with DecylTPP have comparable levels of mitochondrial superoxide to kidneys exposed to CS alone.
Mitoquinone (MitoQ) treatment significantly reduces pancreatic oedema and neutrophil infiltration. MitoQ dose-dependently increases serum amylase with an approximate doubling at the higher dose. MitoQ treatment nearly doubles lung MPO activity induced by Caerulein with a significant increase of serum IL-6 levels also evident at 10 mg/kg (dose 1).
