Multiple pathway drug-resistance (review).
International Journal of Oncology
|May 17, 2011
Summary
Multiple drug resistance mechanisms contribute to treatment failure. Cancer cells employ various pathways to evade chemotherapy, with no single mechanism fully explaining resistance.
Area of Science:
- Oncology
- Pharmacology
- Molecular Biology
Background:
- Drug resistance is a significant challenge in cancer therapy.
- The clinical outcomes of chemotherapy are often limited by the development of resistance.
- Understanding resistance mechanisms is crucial for improving treatment efficacy.
Purpose of the Study:
- To investigate the multifaceted nature of drug resistance in cancer.
- To elucidate the various cellular pathways involved in overcoming chemotherapeutic effects.
- To highlight that no single mechanism explains the full extent of drug resistance.
Main Methods:
- This study reviews existing literature on drug resistance mechanisms.
- Analysis of data from various organs and tumor types expressing resistance phenotypes.
- Examination of cellular pathways utilized to counteract cytotoxic agents.
Main Results:
- Multiple resistance mechanisms are evident in clinical drug resistance.
- The expression of resistance components varies across different organs and tumors.
- Cells activate diverse pathways to resist chemotherapy's cytotoxic effects.
Conclusions:
- Drug resistance is a complex phenomenon driven by multiple, interacting mechanisms.
- A comprehensive understanding of these varied pathways is necessary to overcome resistance.
- Targeting single mechanisms is insufficient to fully address clinical drug resistance.

02:56Treatment Resistant Cancers
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...
01:16Drug toxicity: Idiosyncratic Reactions
Idiosyncratic drug reactions represent abnormal chemical responses that vary significantly among individuals, ranging from extreme sensitivity to low doses to insensitivity to high doses. These reactions often occur due to the drug's covalent binding with serum proteins, forming a foreign hapten that triggers an immunotoxicological response. The variability in drug reactions has a strong pharmacogenetic foundation, with genetic differences crucial in how individuals metabolize drugs. For...
01:29Pharmacogenetic Phenotypes: Alterations in Pharmacokinetics, Drug Targets and Biologic Milieu
Genetic variations significantly influence drug response through pharmacokinetics, receptor interactions, and biologic milieu modifications. Pharmacokinetic alterations impact drug metabolism and clearance, affecting efficacy and toxicity. Variants in drug-metabolizing enzymes, such as CYP2C9 and CYP2C19, alter drug activation and elimination. For example, CYP2C9 loss-of-function variants require lower warfarin doses to prevent excessive bleeding, while CYP2C19 variants reduce clopidogrel...
01:25Mechanism of Antibiotic Resistance in MRSA
Antibiotic resistance in bacteria arises when microorganisms evolve the ability to withstand drugs designed to kill them or inhibit their growth, rendering once-effective treatments useless. This phenomenon, driven by genetic change and selection under antibiotic exposure, poses a profound threat to modern medicine. Mechanisms include drug-inactivating enzymes (e.g., β-lactamases), efflux pumps that eject antibiotics, mutations altering antibiotic targets, decreased drug uptake, and acquisition...
01:27Pharmacogenetics of Drug Metabolism: Overview
Genetic polymorphism in drug metabolism is crucial to the inter-individual variability observed in drug responses. Drug metabolism primarily involves the chemical modification of drugs and other xenobiotics to enhance their elimination by increasing their polarity. Two main classes of enzymes mediate this biotransformation process: Phase I enzymes, primarily cytochrome P450s, catalyze oxidation and reduction reactions, while other enzymes, such as esterases, mediate hydrolysis, and Phase II...
01:21Factors Affecting Drug Response: Overview
When it comes to infants and young children, they are typically administered smaller doses of medication in comparison to adults. This is primarily because their organ functions still need to fully develop, meaning their bodies are not as efficient at metabolizing or eliminating drugs. Additionally, their blood-brain barrier is more permeable than in adults. As a result, high concentrations of drugs can easily penetrate the central nervous system (CNS), potentially leading to neurological...
