Abstract

Insights

Targeting ATP-binding cassette (ABC) transporters can reverse multidrug resistance (MDR) in preclinical cancer studies. However, clinical outcomes remain limited, necessitating novel inhibitors and strategies for effective cancer therapy.

Area of Science:

  • Oncology
  • Pharmacology
  • Molecular Biology

Background:

  • Multidrug resistance (MDR) significantly hinders cancer therapy success.
  • ATP-binding cassette (ABC) transporters actively efflux chemotherapy drugs, contributing to MDR.
  • Emerging evidence implicates ABC transporters in cancer cell signaling pathways beyond drug resistance.

Purpose of the Study:

  • To review the rationale for targeting ABC transporters in cancer treatment.
  • To analyze preclinical and clinical data of ABC transporter inhibitors.
  • To discuss novel strategies for overcoming MDR and the role of ABC transporters in cancer signaling.

Main Methods:

  • Literature review of current research on ABC transporters in cancer.
  • Analysis of preclinical and clinical trial results for ABC transporter inhibitors.
  • Discussion of emerging therapeutic strategies and signaling roles.

Main Results:

  • Preclinical studies show success in reversing MDR using ABC transporter inhibitors.
  • Clinical trials have demonstrated limited impact on patient outcomes to date.
  • ABC transporters play roles in cancer progression distinct from MDR.

Conclusions:

  • Developing safe and effective ABC transporter inhibitors is crucial for improving cancer treatment.
  • Current inhibitors have shown limited clinical efficacy, highlighting the need for new approaches.
  • Further research into novel inhibitors and therapeutic strategies targeting ABC transporters is essential.

ABC Transporters: Exporter01:31

ABC Transporters: Exporter

ATP-binding cassette or ABC transporter is the largest superfamily of integral membrane proteins. The transporters have transmembrane-binding domains (TMDs) and nucleotide-binding domains (NBDs). The TMDs are specific to their substrates, whereas the NBDs are similar to engines that complete ATP hydrolysis to complete the substrate transport. They can be full transporters consisting of two TMDs and NBDs, half transporters with one TMD and NBD, while some encoded with a single TMD or NBD are...
ABC Transporters: Importer01:27

ABC Transporters: Importer

ATP-binding cassette or ABC transporters are a class of ATP-driven pumps that hydrolyze ATP to move solutes across the membrane. They can be grouped into importers and exporters. While exporters are present in all domains of life, importers exist only in bacteria and some plants.
In bacteria, based on the number of transmembrane helices and the chemical nature of their substrates, the ABC importers can be divided into three types:
Pharmacogenetics of Drug Transporters: P-Glycoprotein and Solute Carrier Transporters01:16

Pharmacogenetics of Drug Transporters: P-Glycoprotein and Solute Carrier Transporters

The pharmacogenetics of drug transporters is increasingly recognized as a critical factor influencing interindividual variability in drug absorption, distribution, and elimination. These membrane-bound proteins regulate drugs' movement across cellular barriers by actively pumping them out (efflux) or facilitating their uptake (influx). Among the major transporter families, ATP-binding cassette (ABC) and solute carrier (SLC) transporters play particularly prominent roles. Genetic polymorphisms...
Carrier-Mediated Transport01:06

Carrier-Mediated Transport

Carrier-mediated transport is a pivotal process in drug absorption, particularly for lipid-insoluble drugs, and encompasses facilitated diffusion and active transport. Facilitated diffusion allows drugs to move along their concentration gradient without energy expenditure, while active transport utilizes ATP to drive drug movement against this gradient.
Active transport involves two types of membrane-spanning transporters: uptake and efflux. Uptake transporters are expressed in the small...
Hepatic Drug Clearance: Role of Transporters01:14

Hepatic Drug Clearance: Role of Transporters

In the liver and bile canaliculi, influx and efflux transporters modification can influence intrinsic clearance. Transporters play a significant role in moving drugs within liver cells. Elaborate models, such as the Biopharmaceutical Classification System (BCS), are essential to relate transporters to drug disposition. This system categorizes drugs into four classes based on solubility and permeability, providing insights into elimination routes and the effects of transporters following oral...
Methods for Studying Drug Absorption: In vitro01:16

Methods for Studying Drug Absorption: In vitro

In vitro experiments are crucial for understanding the transport and absorption of drugs through biological materials. These studies employ varied methods such as the diffusion cell method, the everted sac technique, and the everted ring technique.
The diffusion cell method uses a two-compartment cell, including a donor compartment with the drug solution, which simulates the environment where the drug is applied, and a receptor compartment with a buffer solution, which simulates the environment...
