Arazyme is a novel protease produced by the HY-3 strain of Aranicola proteolyticus, which is a Gram-negative aerobic bacterium that has been isolated from the intestine of the spider Nephila clavata. This study focused on the hepatoprotective effect of Arazyme on carbon tetrachloride (CCl4)-induced acute hepatic injury in senescence marker protein 30 (SMP30) knock-out (KO) mice and SMP30 wild-type (WT) mice. WT mice and SMP30 KO mice were divided into eight groups as follows: (i) two negative control groups (G1, G5) which were treated with a single intraperitoneal (i.p.) olive oil injection. (ii) Two positive control groups (G2, G6) which received a single i.p. CCl4 (0.4mL/kg) injection. (iii) Two vitamin C-treated groups (G3, G7) which received a single oral administration of vitamin C (100mg/kg) and were injected with a single i.p. CCl4 (0.4mL/kg). (iv) Two Arazyme-treated groups (G4, G8) which received a single oral administration of Arazyme (500mg/kg) and were injected with a single i.p. CCl4 (0.4mL/kg). Through present study, we could find that Arazyme-treated groups showed decreased degree of liver injury, increased expression of SMP30, decreased expression of phospho-Smad3 (p-Smad3), elevated expression of antioxidant proteins including sorbitol dehydrogenase, dihydropteridine reductase (DHPR), dehydrofolate reductase (DHFR), NADH dehydrogenase, glutathione S-transferase kappa 1 (GSTK1) and phospholipid hydroperoxide glutathione peroxidase (PHGPx) compared with non-Arazyme-treated groups. Therefore, it is concluded that Arazyme plays a significant role in protecting injured hepatocytes by increasing the expression of SMP30, inhibiting the transforming growth factor-beta (TGF-beta)/Smad pathway and elevating the expression of antioxidant proteins.

The basic mechanisms underlying calcineurin inhibitor (CI) nephrotoxicity and its enhancement by sirolimus are still largely unknown. We investigated the effects of CIs alone and in combination with sirolimus on the renal proteome and correlated these effects with urine metabolite pattern changes. Thirty-six male Wistar rats were assigned to six treatment groups (n = 4/group for proteome analysis and n = 6/group for urine (1)H NMR metabolite pattern analysis): vehicle controls, sirolimus 1 mg/kg/day, cyclosporine 10 mg/kg/day, cyclosporine 10 mg/kg/day + sirolimus 1 mg/kg/day, tacrolimus 1 mg/kg/day, tacrolimus 1 mg/kg/day + sirolimus 1 mg/kg/day. After 28 days, 24 h-urine was collected for (1)H NMR-based metabolic analysis and kidneys were harvested for 2D-gel electrophoresis and histology. Cyclosporine affected the following groups of proteins: calcium homeostasis (regucalcin, calbindin), cytoskeleton (vimentin, caldesmon), response to hypoxia and mitochondrial function (prolyl 4-hydroxylase, proteasome, NADH dehydrogenase), and cell metabolism (kidney aminoacylase, pyruvate dehydrogenase, fructose-1,6-bis phosphate). Several of the changes in protein expression, confirmed by Western blot, were associated with and explained changes in metabolite concentrations in urine. Representative examples are an increase in kidney aminoacylase expression (decrease of hippurate concentrations in urine), up regulation of pyruvate dehydrogenase and fructose-1,6-bisphosphatase, (increased glucose metabolism), and down regulation of arginine/glycine-amidino transferase (most likely due to an increase in creatinine concentrations). Protein changes explained and qualified immunosuppressant-induced metabolite pattern changes in urine.
