Insights

Multiple drug resistance (MDR) in cancer hinders chemotherapy. Targeting ATP binding cassette (ABC) transporters, which cause MDR, offers a promising strategy to improve cancer treatment efficacy.

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Oncology

Background:

  • Multiple drug resistance (MDR) significantly reduces chemotherapy effectiveness in cancer treatment.
  • Overexpression of ATP binding cassette (ABC) transporters is a primary mechanism driving MDR by exporting drugs from cancer cells.

Purpose of the Study:

  • To review recent advancements in understanding cancer-related ABC transporters.
  • To explore the physiological functions and structures of key ABC transporters.
  • To highlight the development of novel ABC transporter inhibitors for combination therapy.

Main Methods:

  • Literature review of recent scientific publications.
  • Analysis of the roles of ABC transporters in cancer drug resistance.
  • Summary of emerging ABC transporter inhibitor compounds.

Main Results:

  • ABC transporters are crucial in mediating MDR by facilitating drug efflux.
  • Understanding ABC transporter structure and function is key to developing effective inhibitors.
  • Inhibitors of ABC transporters show potential for enhancing standard chemotherapy.

Conclusions:

  • Modulating ABC transporter activity is a viable strategy to overcome MDR.
  • Combination therapy with ABC transporter inhibitors and chemotherapeutics may improve patient outcomes.
  • Further research into novel ABC transporter inhibitors is warranted.

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: 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:

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...

Treatment Resistant Cancers02:56

Treatment 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...

Combination Therapies and Personalized Medicine

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

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...
