Abstract
RELEVANCE: Malignant peritoneal sarcomatosis related ascitic formation often leads to grave consequences but the therapeutic management of the fatal pathophysiological condition remains a rarely discussed issue. The present study investigates the anti-neoplastic activity of the plant alkaloid from Ruta graveolens on ascitic Sarcoma-180 bearing mice as a model of human malignant peritoneal ascites. MATERIALS AND METHODS: The efficacy of the loco-regional administration of Ruta graveolens on tumour cells was explored with cytopathological and cytotoxicological studies, along with the expressional modulation vital regulatory molecules viz. Chk2, c-Myc, CD95 and Aurora kinase. RESULTS: The study revealed a series of anti-neoplastic events exerted by Ruta graveolens that included the boosting of anti-tumour immunity, generation of tumour cell cytotoxicity and disruption of cellular energetics which lead to the induction of apoptosis and simultaneous impairment of cell division in tumour cells. Expressional decline of c-Myc oncoproteins and mitosis promoter Aurora kinase A together with up regulation of vital tumour suppressor Chk-2 and apoptosis inducer CD 95 in ascitic tumour cells was also found to be associated with Ruta administration. CONCLUSION: Our observations revealed that loco-regional Ruta administration resulted in the anti-neoplastic effect on peritoneal sarcoma related ascites and the alteration of vital regulatory molecules which depicted the therapeutic utility of Ruta in the management of peritoneal malignant ascites.
