S-allyl cysteine ameliorates cyclophosphamide-induced downregulation of urothelial uroplakin IIIa with a concomitant effect on expression and release of CCL11and TNF-α in mice.
    Pharmacological reports : PR, 2018, Volume: 70, Issue:4

    The aim of this study was to evaluate the modulatory effect of S-allyl cysteine against cyclophosphamide-induced changes in uroplakin IIIa, CCL11 and TNF-α.. Mice were treated with cyclophosphamide (200mg/kg×7 d, ip). S-allyl cysteine (150mg/kg×7d, ip), and comparator compound mesna (40mg/kg×7d, ip) were administered 1h before and 4h after each cyclophosphamide dose. The urinary bladder was analysed for mRNA and protein changes in uroplakin IIIa (UPIIIa), CCL11 and TNF-α and histopathological findings.. Cyclophosphamide caused hemorrhagic cystitis formation and downregulation of UPIIIa. These changes were accompanied by upregulation of CCL11 and TNF-α. S-allyl cysteine attenuated these changes including protection at histological level. Mesna which was used as a comparator drug also showed protection. However, relatively S-allyl cysteine showed a stronger protective effect than mesna.. These findings highlight a correlation between downregulaion of UPIIIa and enhanced production of inflammatory biomarkers and protective effects of S-allyl cysteine which has been reported to be a potent uroprotective agent. The present study strengthens its role which could be clinically exploited in chemotherapy regimen.

Cyclophosphamide-induced Down-Regulation of Uroplakin II in the Mouse Urinary Bladder Epithelium is Prevented by S-Allyl Cysteine.
    Basic & clinical pharmacology & toxicology, 2016, Volume: 119, Issue:6

    The alkylating anticancer drug, cyclophosphamide (CP), induces a number of toxic effects including haemorrhagic cystitis (HC) in the urinary bladder. Uroplakins are unique urinary transmembrane proteins of urothelium, which may become potential targets of CP metabolites and reactive free radicals. Natural compounds, especially those rich in thiols, have shown protective effects against CP-induced HC. In this study, we studied the modulatory effect of the thiol-rich compound S-allyl cysteine (SAC) on the mRNA level of uroplakin II by real-time polymerase chain reaction and expression of uroplakin II protein by immunoblotting. SAC (150 mg/kg) showed significant (p < 0.001) protective effects against CP (200 mg/kg)-induced alteration in mRNA level and protein expression of uroplakin II. SAC also protected animals from CP-induced HC as assessed by gross morphological examination of urinary bladder. When compared with mercaptoethane sulphonic acid (mesna) (40 mg/kg), a known thiol-rich drug used in clinical application, SAC was found to be more efficacious in affording protection in urinary bladder tissues. Role of uroplakins in CP-induced urinary bladder toxicity has not been well investigated. This study demonstrated that uroplakins may be the potential target of toxic metabolites of CP and natural compounds such as SAC have the capacity to modulate their expression leading to reduced toxicity burden on the urinary bladder epithelium.

Protective effect of S-allylcysteine against cyclophosphamide-induced bladder hemorrhagic cystitis in mice.
    Food and chemical toxicology : an international journal published for the British Industrial Biological Research Association, 2008, Volume: 46, Issue:11

    S-Allylcysteine (SAC), an organosulfur compound of aged garlic extract (AGE) regulates the thiol status of the cell and scavenges free radicals. Depletion of thiols along with free radical generation has been implicated in cyclophosphamide (CP)-induced urotoxicity. We studied modulatory effect of SAC on CP-induced urotoxicity in mice focusing on hemorrhagic cystitis (HC). SAC (150 and 300 mg kg(-1)) was administered in CP treated animals (200 mg kg(-1)) and bladder was observed for histological and biochemical changes. CP treatment caused a marked increase in the lumen exudates, edema, vasodilation and HC in lamina propia in the bladder. These changes were accompanied by increase in lipid peroxidation (LPO), and decrease in reduced glutathione (GSH) and activities of antioxidant enzymes. SAC not only showed protection in tissue histology but also improved the decreased activities of antioxidant enzymes. SAC treatment also reduced LPO and increased GSH levels. Although SAC treatment did not ensure full recovery, the marked improvement in histology and antioxidants of bladder suggests that it has a significant modulatory effect on CP-induced urotoxicity. Since decrease in antioxidant level is the major cause of CP urotoxicity, the protective effect of SAC deserves its further exploration involving laboratory and clinical investigations.
