  • Title: A general survey of glutamine level in different tissues of murine solid tumor bearing mice before and after therapy with purified glutaminase.

    Abstract:
    Distribution of glutamine level in different tissues of tumor bearing mice such as brain, liver, kidney, spleen, large and small intestine and the tumor itself were studied in three solid tumor models, viz, Ehrlich ascites carcinoma, Sarcoma-180 and methylcholanthrene induced carcinoma. Tumor bearing mice were subjected to therapy for 7 days with the glutaminase purified from malignant S-180 cell. The results exhibit a significant decrease in tumor burden after enzyme therapy. Host tissue glutamine levels were significantly elevated in tumor bearing untreated mice in comparison to the normal ones, while significant lower values were obtained after enzyme therapy. It therefore appears that elevated levels of glutamine in host tissue are associated with the tumor burden.
