Austin Doyle, M.D and Percy Ivy, M.D RFA-CA-17-009 for Studies of Mechanisms of Cancer Resistance or Sensitivity to Therapy Original FY-2017 Moonshot RFA Establish multi-disciplinary research teams to elucidate the complex mechanistic underpinnings of drug resistance and to inform future clinical …... Drug Resistance in Cancer: An Overview Genevieve Housman 1, Shannon Byler 2, Sarah Heerboth 2, Overall, drug inactivation is a mechanism of cancer drug resistance that warrants further investigation. 2.2. Alteration of Drug Targets A drug’s efficacy is influenced by its molecular target and alterations of this target, such as mutations or modifications of expression levels. In cancers

Antineoplastic resistance, often used interchangeably with chemotherapy resistance, is the multiple drug resistance of neoplastic (cancerous) cells, or the ability of cancer cells to survive and grow despite anti-cancer therapies.... Review Understanding the Genetic Mechanisms of Cancer Drug Resistance Using Genomic Approaches Xueda Hu1 and Zemin Zhang1,2,* A major obstacle in precision cancer medicine is the inevitable resistance to

Multiple Drug Resistance Mechanisms in Cancer Springer
biochemical mechanisms of drug resistance, the types of mutations in tumor cells that can alter drug handling are discussed. Three examples of resistance are analysed in more detail: resistance to the folate analogue methotrexate; the multidrug resistance caused by increased levels of P-glycoprotein, which extrudes drugs from the cell; and resistance to alkylating agents. Key wordr: Cancer geomorphology the mechanics and chemistry of landscapes pdf Clinical trials have been initiated with agents that may inhibit the biochemical mechanisms of acquired drug resistance. Clinical trials are already in progress with alkylating agents combined with inhibition of GSH biosynthesis (i.e., buthionine sulfoximine) or enzymatic inhibitors of glutathione S?transferase activity (i.e., ethacrynic acid). Furthermore, the combination of aphidicolin, an

REVIEW Multiple Drug Resistance Mechanisms in Cancer Bruce C. Baguley Published online: 18 August 2010 Springer Science+Business Media, LLC 2010 Abstract Multiple drug resistance (multidrug resistance;
- Cancer remains one of the major leading causes of death worldwide. Acquisition of multidrug resistance (MDR) remains a major impediment to successful chemotherapy. As the name implies, MDR is not limited only to one drug but often associated to structurally and functionally unrelated chemotherapeutics. Extensive research and investigations have identified several mechanisms …
- Multidrug resistance is a major problem in successful cancer chemotherapy. Various mechanisms of resistance, such as ABC transporter-mediated drug efflux, have been discovered using established model cancer cell lines. While characterizing a drug-resistant breast cancer …
- Outcomes will include important pathomechanistic knowledge of the molecular dynamics underlying drug resistance in cancer, which could lead to better diagnostic and therapeutic opportunities. Clinical proteomic analysis of tumour cells will identify adaptive mechanisms of drug resistance, enabling orthogonal targeting of mechanistically relevant systems.
- Unfortunately, these drug and multi-drug resistance mechanisms are poorly understood at the molecular level, impeding our advances towards identifying new targets for possible inhibition of clinical multi-drug resistances; this prevents chemotherapeutic usefulness.
