Pharmacogenetics of ATP-binding cassette transporters in cancer and chemotherapy.
نویسندگان
چکیده
The ATP-binding cassette (ABC) transporters belong to the largest known transporter gene family and translocate a variety of substrates including chemotherapy agents. ABC multidrug transporter expression has been implicated in tumor cell resistance to anticancer therapy, altered disposition of chemotherapy drugs, and associated chemotherapy toxicity. More recently, genetic heterogeneity has been described in a number of the ABC transporter genes, including ABC transporters that contribute to the pharmacokinetics and/or pharmacodynamics of chemotherapy drugs. The role of these transporters and their naturally occurring genetic polymorphisms in cancer and chemotherapy is reviewed.

Background: ATP-binding cassette membrane transporter G2 (ABCG2) gene is one of transporter family and well characterized for their association with chemoresistance. Promoter methylation is a mechanism for regulation of gene expression. O6-Methyl guanine DNA methyl transferase (MGMT) gene plays a fundamental role in DNA repair. MGMT has the ability to remove alkyl adducts from DNA at the O6 pos...

Some varieties of human cancers become resistant, or, are intrinsically resistant to treatment with conventional drug therapies. This phenomenon is due largely to over-expression of the ATP binding cassette, (ABC), super-family of membrane transporters. In this regard, 170 kDa plasma membrane ATP-dependent pump, known as P-glycoprotein are the most important. Other members of multi-drug resista...
متن کاملEffects of Salinispora derived metabolites against multidrug resistance, an in-silico study
Background: Multidrug resistance (MDR) is known to defeat most chemotherapies as one of the main anticancer strategies. The role of overexpression/overactivation of ABC transporters, especially P-glycoprotein (P-gp), in the development of chemotherapy has long been demonstrated. Salinispora is a marine actinomycete genus known for the production of novel bioactive metabolites. Methods: In this...
متن کاملThe role of ATP-binding cassette transporter A2 in childhood acute lymphoblastic leukemia multidrug resistance
Acute lymphoblastic leukemia (ALL) is one of the most prevalent hematologic malignancies in children. Although the cure rate of ALL has improved over the past decades, the most important reason for ALL treatment failure is multidrug resistance (MDR) phenomenon. The current study aims to explain the mechanisms involved in multidrug resistance of childhood ALL, and introduces ATP-binding cassette...
متن کاملATP Binding Cassette transporters associated with chemoresistance: transcriptional profiling in extreme cohorts and their prognostic impact in a cohort of 281 acute myeloid leukemia patients.
BACKGROUND A major issue in the treatment of acute myeloid leukemia is resistance to chemotherapeutic drugs. An increasing number of ATP-Binding-Cassette transporters have been demonstrated to cause resistance to cancer drugs. The aim of this study was to highlight the putative role of other ATP-Binding-Cassette transporters in primary chemoresistant acute myeloid leukemia. DESIGN AND METHODS...
