Abstract:
Cancer is one of the leading causes of mortality in the developed countries. The search for novel drug candidates is a priority goal for cancer therapy. However, the emergence of drug resistance reduces the effectiveness of new medications. The ATP binding cassette (ABC) family of proteins are efflux pumps that transport various structurally unrelated and potentially dangerous substances out of the cells. These transporters have evolved as a complex cellular defense system, for the recognition and removal of toxic agents entering the cells from their environment. Several of the ABC transporters are related to chemoresistance in cancer therapy, as the rapidly dividing malignant cells use them to protect themselves from medical interventions. Here we review the members of the ABC transporter families responsible for the multidrug resistance in anticancer therapy.
Insights
Drug resistance is a major challenge in cancer therapy. This review focuses on ATP binding cassette (ABC) transporters, which enable cancer cells to expel chemotherapy drugs, leading to multidrug resistance.
Area of Science:
- Oncology
- Molecular Biology
- Pharmacology
Background:
- Cancer remains a leading cause of death globally, necessitating novel therapeutic strategies.
- Drug resistance significantly compromises the efficacy of existing and emerging cancer treatments.
- ATP binding cassette (ABC) proteins function as cellular efflux pumps, removing toxic substances.
Purpose of the Study:
- To review the role of ATP binding cassette (ABC) transporter families in multidrug resistance within cancer therapy.
- To elucidate how cancer cells utilize ABC transporters as a defense mechanism against chemotherapy.
Main Methods:
- Literature review of scientific articles and research papers.
- Analysis of the function and implications of ABC transporter families in cancer drug resistance.
- Synthesis of information on specific ABC transporters involved in multidrug resistance.
Main Results:
- Several ABC transporter families are identified as key mediators of multidrug resistance in cancer.
- These transporters enable cancer cells to recognize and expel a wide range of chemotherapeutic agents.
- The cellular defense system involving ABC transporters contributes to treatment failure.
Conclusions:
- Understanding the mechanisms of ABC transporters is crucial for overcoming chemoresistance.
- Targeting specific ABC transporters may offer new avenues for improving anticancer drug efficacy.
- Further research into ABC transporter inhibitors is warranted for effective cancer treatment.
