Insights

Multidrug resistance (MDR) in cancer chemotherapy is often caused by P-glycoprotein (P-gp). Understanding P-gp

Area of Science:

  • Oncology
  • Molecular Biology
  • Drug Discovery

Background:

  • Multidrug resistance (MDR) significantly limits the efficacy of cancer chemotherapy.
  • P-glycoprotein (P-gp) is a key efflux pump overexpressed in cancer cells, contributing to MDR.
  • Previous strategies to inhibit or evade P-gp have shown limited clinical success.

Purpose of the Study:

  • To review progress and challenges in developing drugs to overcome P-gp-mediated MDR.
  • To highlight the importance of molecular-level understanding of drug-P-gp interactions.
  • To discuss strategies for inhibiting or evading P-gp efflux.

Main Methods:

  • Literature review of studies on P-gp inhibitors and modulators.
  • Analysis of recent advancements in understanding P-gp structure and function.
  • Discussion of novel drug development and delivery strategies.

Main Results:

  • Despite extensive research, clinical success in circumventing P-gp-mediated MDR remains limited.
  • Improved understanding of P-gp's structural basis and mechanism is crucial for effective drug development.
  • Alternative strategies like drug modification and novel delivery systems are being explored.

Conclusions:

  • Overcoming P-gp-mediated MDR requires a deeper molecular understanding of drug interactions.
  • Future drug development must leverage structural insights into P-gp.
  • Continued research into novel strategies is essential for improving cancer chemotherapy outcomes.

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...

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...

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

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...

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...

Inhibition of Cdk Activity02:34

Inhibition of Cdk Activity

The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be restricted when undergoing abnormal changes. Most cancers correlate to the deregulated cell cycle, and since Cdks are a central component of the cell cycle, Cdk inhibitors are extensively studied to develop anticancer agents. For instance, cyclin D associates with several Cdks, such as Cdk 4/6, to form an active complex. The cyclin D-Cdk4/6 complex...
