Uridine is a nucleoside that contains uracil and is linked to the ribose ring through a β-N1-glycosidic bond [1]. Uridine regulates enzymes and intermediates in the Uridine metabolism (such as UTP, DHODH, and UPase) and is associated with glucose homeostasis, lipid metabolism, and amino acid metabolism [2-3].
In vitro, Uridine (6-24mM; 7 days) dose-dependently inhibits the proliferation of leukemia cells HL-60 and induces HL-60 to differentiate into mature cells with monocyte and granulocyte characteristics [1]. Uridine (0.2-0.4mg/mL; 10h) reduces hepatocyte apoptosis caused by CCl4, significantly reduces the expression of Caspase-3 and Bax, and upregulates Bcl-2 expression [4].
In vivo, Uridine (10-20mg/kg; oral; 6 weeks) alleviates liver fibrosis in mice with CCl4-induced liver fibrosis model and inhibits the expression of pro-inflammatory cytokines and the activation of the NF-κB signaling pathway [4]. Uridine (30mg/kg; iv; single dose) significantly increases the UDP and UTP contents in the myocardium of rats with acute myocardial ischemia (AMI) and ischemia/reperfusion injury (I/R), reduces CrP and ATP levels, and significantly reduces the size of the ischemic area in the myocardium [5].

البروتوكول (Protocol)
| Cell experiment [1]: | |
Cell lines | AML12 cells |
Preparation Method | To avoid the adverse effects of hepatocyte injury produced during perfusion, the mouse hepatocyte cell line (AML12, the mouse hepatocyte cell line) was also used to check the protective effects of Uridine on hepatocytes apoptosis caused by CCl4. Before 4h prior to treatment with 10mmol/L CCl4 for 10h, the hepatocytes were treated with Uridine (200µg/ml) or the vehicle (DMSO). Cell apoptosis rate was assessed using a PE Annexin V apoptosis detection kit according to the manufacturer's instructions. The cell samples were analysed with a FACSCalibur flow cytometer (Becton-Dickinson), and cells that are viable are Annexin V-PE and 7-AAD negative; cells that are in early apoptosis are Annexin V-PE positive and 7-AAD negative; and cells that are in late apoptosis or already dead are both Annexin V-PE and 7-AAD positive. |
Reaction Conditions | 200µg/ml; 10h |
Applications | Uridine reduced hepatocyte apoptosis induced by CCl4, significantly decreased the expression of Caspase-3 and Bax, and upregulated the expression of Bcl-2. |
| Animal experiment [1]: | |
Animal models | C57BL/6J mice |
Preparation Method | The establishment of the experimental mouse model was approved by the Animal Ethics Committee of the Intervention and Cell Therapy Center of Peking University Shenzhen Hospital. 30 healthy C57BL/6J mice were chosen (6–7 weeks old, weighing between 19 ± 2g) and randomly divided them into control group, model group and Uridine treatment group. Model group: CCl4 was mixed with olive oil into a 10% oily solvent, the mice from the model group were injected intraperitoneally with the mixed solution at 0.6μl/g twice per week for 8 weeks; Control group: the C57BL/6J mice were injected intraperitoneally with the same volume of olive oil at the same time point (as negative control); Uridine treatment group, the mice were given Uridine by drinking water (10–20mg/kg) for 6 weeks. Twenty‐four hours after the last injection, the eyeballs of experimental animals were removed and blood was collected. The mice were anaesthetized and perfused with saline. The liver tissues were collected for a series of biological analyses. |
Dosage form | 10-20mg/kg/day for 6 weeks; oral |
Applications | Uridine alleviated liver fibrosis in mice with CCl4-induced liver fibrosis model, and inhibited the expression of pro-inflammatory cytokines and the activation of the NF-κB signaling pathway. |
