“…Over the past two decades, many studies have demonstrated the action of indole compounds as potentially effective agents against bladder cancer, such as indole-3-acetic acid [4], Go-6976 [5], apaziquone [6], 5-hydroxyindole-3-acetic acid [7], arylindolylpropenones [8], and 3,3 ′ -diindolylmethane [9]. In this context, indole-3-carbinol (I3C) is an indole compound produced endogenously from natural glycosinolates contained in a wide variety of plant food substances, including members of the Cruciferae family, and particularly members of the genus Brassica, such as broccoli, cabbage, cauliflower, brussels sprouts, china cabbage, radish, turnip and rapeseed [10], being one of the metabolites resulting from the enzymatic oxidation of indole-3acetic acid [11], as well as to be the precursor of 3,3 ′ -diindolylmethane [12].…”

“…34 Bioactive molecules such as DIM prevented cancer through inhibiting cellular oxidation and modulating drug metabolizing enzymes that may be useful adjuncts in the prevention of bladder cancer. 35 Lupeol was reported to modulate several molecules that directly or indirectly play a role in inflammatory process. 19 Lupeol treatment inhibited cell survival by inactivation of NF-κB in human epidermoid carcinoma cells.…”

Introduction: Chemoprevention may involve perturbation of a variety of steps in tumor initiation, promotion, and progression. Objective: To investigate the antiproliferative and anti-inflammatory potential effects of diindolylmethane (DIM) and lupeol on experimental bladder carcinogenesis. Methods: Sixty healthy male Wistar rats were selected and randomly divided into six groups, with 10 rats in each group. Group I: control; group II: N-butyl- N-(4-hydroxybutyl) nitrosamine (BBN; 150 mg/gavage/twice a week) for 8 weeks, and then they were given 100 ppm concentrations of dimethylarsenic acid (DMA) in the drinking water for 28 weeks; group III: BBN + DMA + DIM (5 mg/kg body weight (b.w.)/day) treatment was started after BBN treatment, and it was orally administered for 28 weeks); group IV: BBN + DMA + lupeol (50 mg/kg b.w./day) treatment was started after BBN treatment, and it was orally administered for 28 weeks); and groups V and VI: DIM and lupeol treatment alone for 36 weeks. Bladder tissues were collected after 36th week study protocol for further analysis. Results: Our results revealed that DIM and lupeol treatment showed inhibition of tumor growth in the bladder by histopathological confirmations as well as significantly ( p < 0.001) increased the expression of phosphotensin (PTEN) and significantly ( p < 0.001) decreased the expression of tumor necrosis factor α, nuclear factor κβ (p65) were quantified using Western blot analysis. DIM and lupeol treatment significantly ( p < 0.001) decreased the levels of Cox-2 in bladder tissue samples and NMP 22 in urine samples were quantified using enzyme-linked immunosorbent assay method. Conclusion: Preventive DIM and lupeol administration act as potent Cox-2 inhibitors, which activates the tumor suppressor protein PTEN against experimental bladder carcinogenesis by antiproliferative and anti-inflammatory properties.

Bladder cancer has been shown to resist programmed cell death with altered expression of both pro-apoptotic and anti-apoptotic proteins. To study is to investigate the apoptotic properties of Diindolylmethane (DIM) and Lupeol on N-Butyl-N-(4-hydroxybutyl) Nitrosamine (BBN) initiated and Dimethylarsinic Acid (DMA) promoted urinary bladder cancer. Sixty male Wistar rats were divided into 6 groups. Group I: Control. Group II: Rats were experimentally developed bladder carcinogenesis with BBN and DMA. Group III and IV: DIM and lupeol were administered after BBN treatment for 28 weeks. Group V and VI: DIM and lupeol alone treatment for 36 weeks. All the experimental rats were maintained and euthanized after 36 weeks protocol. Urinary bladder tissues were collected and processed for further investigations. Apoptotis and cell proliferative marker such as Bax, Bcl-2, caspase-3, caspase-9 and PCNA were quantified using immunohistochemical analysis. The Immunohistochemical expression of Bax, Bcl-2, caspase-3, caspase-9 and PCNA were aberrant in BBN + DMA treated tumor group. Administration of DIM and lupeol inhibited the progression of bladder cancer, induced the expression of apoptotic Bax, caspase-3, caspase-9 and inhibited the expression of anti-apoptotic Bcl-2, PCNA in the urinary bladder of rats. Administration of diindolylmethane and lupeol treatment induces apoptosis and cellular proliferation by its anti-carcinogenic properties. From our results DIM and lupeol would be the agent or adjunct for the treatment of bladder carcinogenesis.
