Insights

Multidrug resistance (MDR) in breast cancer hinders treatment. Nanodelivery offers a promising strategy to bypass drug efflux transporters and overcome resistance, improving patient outcomes.

Area of Science:

  • Oncology
  • Nanotechnology
  • Pharmacology

Background:

  • Breast cancer poses a significant health risk to women globally.
  • Multidrug resistance (MDR) is a major challenge in breast cancer treatment, negatively impacting prognosis.
  • Key MDR-associated proteins include P-glycoprotein (ABCB1), multidrug resistance protein-1 (MRP1, ABCC1), and breast cancer resistance protein (BCRP, ABCG2).

Purpose of the Study:

  • To review the role of MDR-associated proteins in breast cancer.
  • To explore nanodelivery systems as a strategy to overcome MDR in breast cancer.
  • To discuss passive and active tumor targeting strategies utilizing nanoparticles.

Main Methods:

  • Literature review focusing on MDR mechanisms in breast cancer.
  • Analysis of nanoparticle formulations designed for cancer therapy.
  • Examination of drug delivery strategies to target tumor tissues.

Main Results:

  • Nanodelivery systems can bypass multispecific drug efflux transporters implicated in MDR.
  • Passive and active tumor targeting strategies enhance drug accumulation in tumor tissues.
  • Nanoparticle formulations show potential in reducing or reversing drug resistance in breast cancer models.

Conclusions:

  • Nanodelivery represents a promising approach to combat MDR in breast cancer.
  • Targeted delivery of anticancer agents via nanoparticles can improve therapeutic efficacy.
  • Further research into nanoparticle formulations and targeting strategies is warranted to enhance breast cancer treatment.

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...

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...

Site-Targeted Drug Delivery Systems: Polymeric Carriers

Polymeric carriers enhance targeted drug delivery by increasing efficacy while minimizing off-target effects. These carriers comprise a biodegradable polymeric backbone integrated with functional elements that enable targeting, improve physicochemical properties, and regulate drug release.Targeting MechanismsThe targeting ability of polymeric carriers is mediated by a homing device, which is a molecular recognition component designed to selectively bind to specific tissues or cells.

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...

Modified-Release Drug Delivery Systems: Site-Targeted

Site-targeted drug delivery systems enhance therapeutic efficacy while minimizing systemic toxicity and treatment costs. Unlike conventional methods, these systems ensure precise drug delivery, improving bioavailability and reducing side effects. Targeted drug delivery is classified into three levels. First-order targeting directs drugs to the capillary beds of specific organs or tissues. Second-order targets specific cell types, such as tumor cells, using receptor-mediated interactions.
