Area of Science:

  • Oncology
  • Nanotechnology
  • Pharmacology

Background:

  • Multidrug resistance (MDR) in tumor cells is a major obstacle in cancer therapy, driven by complex mechanisms like drug efflux and altered targets.
  • Traditional chemotherapy faces significant challenges due to tumor MDR, necessitating innovative treatment strategies.

Purpose of the Study:

  • To explore the potential of nanoparticles in overcoming cancer multidrug resistance.
  • To highlight the advantages of nanocarriers for enhancing anticancer drug delivery and efficacy.

Main Methods:

  • Review of existing literature on nanoparticle-based drug delivery systems for cancer.
  • Analysis of mechanisms by which nanoparticles can reverse MDR and improve drug accumulation in tumor cells.

Main Results:

  • Nanoparticles demonstrate improved stability, prolonged half-life, and enhanced tumor-specific drug delivery compared to conventional methods.
  • Drug-carrying nanoparticles have shown the ability to reverse MDR, increasing the effectiveness of cytotoxic agents.
  • Multifunctional nanoparticles can simultaneously deliver drugs, genes, and imaging agents for enhanced anti-tumor toxicity and tracking.

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 specific...
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 Medicine02:50

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...

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.
