While colony formation assays provide sensitive indices of tumor cell proliferation and growth inhibition imposed by many Chemotherapeutic agents, drugs which require metabolic acti vation lack activity in such assays. In the present study, we have utilized freshly isolated rat hepatocytes for the activation of drugs which are metabolized by hepatic microsomal as well as extramicrosomal enzymes...

While colony formation assays provide sensitive indices of tumor cell proliferation and growth inhibition imposed by many chemotherapeutic agents, drugs which require metabolic activation lack activity in such assays. In the present study, we have utilized freshly isolated rat hepatocytes for the activation of drugs which are metabolized by hepatic microsomal as well as extra-microsomal enzymes...

PURPOSE Antiangiogenic drug treatment inhibits tumor growth by decreasing blood supply, which can also reduce the delivery of other therapeutic agents. Presently, we investigated the effect of the vascular endothelial growth factor receptor tyrosine kinase inhibitor axitinib (AG-013736) on tumor vascular patency and chemotherapeutic drug uptake. Furthermore, the effect of axitinib on the antitu...

Cyclophosphamide, one of the most efficient tumoricidal, antiangiogenic, and immunostimulatory drugs employed to date mediates part of its effects through intestinal bacteria, against which the host becomes immunized during treatment. Our recent work suggests that anti-commensal effector pTH17 and memory TH1 CD4+ T-cell responses are indispensable for optimal anticancer effects as mediated by c...

The purpose of the present work was to evaluate anticarcinogenic and cytotoxic potential of Hemidesmus indicus methanolic root extract (HiRe) against Ehrlich Ascites Tumor. The extract showed a significant in vitro cytotoxic activity against Ehrlich Ascites Tumor (EAT) cell line. IC50 value for EAT cell line was 274.83μg.The anticarcinogenic activity of the extract was determined by using EAT c...

Most anticancer drugs (epirubucin, adriamycin, bleomycin, vincristin, cyclophosphamide) exert their cytotoxic effect by free radicals-mediated mechanisms. The purpose of this study was to establish whether the antioxidants co-administered with epirubicin and cyclophosphamide reduce the adverse side effects of cytostatic chemotherapy without affecting their efficacy in dogs with spontaneous mamm...

Chemoimmunotherapy in two animal models for urological cancers was studied. The models were Dunning R3327A prostatic carcinoma transplanted s.c. in Fischer x Copenhagen F, hybrids and a well-differentiated bladder carcinoma transplanted orthotopically in the bladder submucosa of female Fischer rats. Cyclophosphamide, c/s-platinum, and Adriamycin were initially used as anticancer chemotherapeuti...

Chemoimmunotherapy in two animal models for urological cancers was studied. The models were Dunning R3327A prostatic carcinoma transplanted s.c. in Fischer X Copenhagen F1 hybrids and a well-differentiated bladder carcinoma transplanted orthotopically in the bladder submucosa of female Fischer rats. Cyclophosphamide, cis-platinum, and Adriamycin were initially used as anticancer chemotherapeuti...

The aim of the present study was to establish screening biomarkers of exposure to antineoplastic drugs administered to 11 patients undergoing cancer chemotherapy. Among the anticancer drugs administered were cyclophosphamide (all), Adriamycin (5 of 11), methotrexate (3 of 11), 5-fluorouracil (4 of 11), vincristine (3 of 11), megestrol acetate (1 of 11), and procarbazine (1 of 11). The noninvasi...

INTRODUCTION Cardiac toxicity is one of the life-threatening complications of cancer therapy. Systemic anticancer treatments may exert their own toxic effects or can aggravate adverse effects of other drugs. We report a case of cyclophosphamide-induced cardiotoxicity in a patient with normal cardiac functions before chemotherapy. CASE PRESENTATION A 66-year-old Caucasian woman with a mediasti...
