Cancer Therapy: Preclinical Killing of Chronic Lymphocytic Leukemia by the Combination of Fludarabine and Oxaliplatin Is Dependent on the Activity of XPF Endonuclease
نویسندگان
چکیده
Purpose: Chronic lymphocytic leukemia (CLL) resistant to fludarabine-containing treatments responds to oxaliplatin-based therapy that contains fludarabine. We postulated that a mechanism for this activity is the incorporation of fludarabine into DNA during nucleotide excision repair (NER) stimulated by oxaliplatin adducts. Experimental Design: We analyzed CLL cell viability, DNA damage, and signaling pathways in response to treatment by fludarabine, oxaliplatin, or the combination. The dependency of the combination on oxaliplatin-induced DNA repair was investigated using siRNA in CLL cells or cell line models of NER

متن کاملFludarabine increases oxaliplatin cytotoxicity in normal and chronic lymphocytic leukemia lymphocytes by suppressing interstrand DNA crosslink removal.
Oxaliplatin and fludarabine have different but potentially complementary mechanisms of action. Previous studies have shown that DNA repair is a major target for fludarabine. We postulate that potentiation of oxaliplatin toxicity by fludarabine may be due to the inhibition by fludarabine of the activity of the DNA excision repair pathways activated by oxaliplatin adducts. To test this, we invest...

The standard therapy for thyroid cancer is total or near total thyroidectomy, followed by the administration of radioactive iodine for remnant ablation or residual disease. Patients with radioiodine therapy are predisposed to second malignant neoplasms in organs such as central nervous system (CNS), breast, prostate, kidney, bone marrow, salivary gland, and digestive tract. Exposure to carcinog...

Introduction: Chronic lymphocytic leukemia (CLL) is the most frequent leukemia in adults living in Western countries. with a diverse clinical course that due to life expectancy less than two years between patients finding ,new therapeutic strategies is essential for it. Curcumin as the biologic active of turmeric, has many biological properties such as anti-inflammatory, anti-oxidant, anti-diab...
متن کاملComparison Cytotoxic Effects of Mangifera Indica L. and Juglans Regia Aqueous Extract on Human Chronic Lymphocytic Leukemia
Natural products isolated from plant sources are well known for their pharmacological potential in diversity of disease treatments such as inflammatory or cancer conditions. Mango (Mangifera indica L.) and Juglans regia are thought to be rich of functional phytochemicals. To elucidate the anticancer activity of Juglans regia (JR) and Mangifera indica L (MI) aqueous extract were investigated on ...
