Molecular Mechanisms of Insecticide Resistance.

The molecular genetics of insecticide resistance.

The past 60 years have seen a revolution in our understanding of the molecular genetics of insecticide resistance. While at first the field was split by arguments about the relative importance of mono- vs. polygenic resistance and field- vs. laboratory-based selection, the application of molecular cloning to insecticide targets and to the metabolic enzymes that degrade insecticides before they ...

Molecular mechanisms involved in multidrug resistance in breast cancer therapy

Breast cancer is the most prevalent cancer in women. Chemotherapy is the main strategy in the treatment of this disease especially in the advanced form of the disease. Despite the recent progress in the development of new chemotherapy, the effectiveness of these drugs has dramatically reduced due to multidrug resistance. The phenotype of multidrug resistance (MDR) can occur through different me...

The molecular basis of two contrasting metabolic mechanisms of insecticide resistance.

The esterase-based insecticide resistance mechanisms characterised to date predominantly involve elevation of activity through gene amplification allowing increased levels of insecticide sequestration, or point mutations within the esterase structural genes which change their substrate specificity. The amplified esterases are subject to various types of gene regulation in different insect speci...

Molecular mechanisms of drug resistance.

Molecular Mechanisms of Antimicrobial Resistance

In the last 50 years bacteria have demonstrated a remarkable ability to develop and share resistance to every antibiotic that has been developed, often by quite unexpected mechanisms and much more readily than was originally predicted (Spratt, 1994). Antibiotic resistant bacteria can live and multiply in the presence of therapeutic levels of antibiotics. They can be resistant in their natural s...
