Insights

This review explores multidrug resistance (MDR) in metastatic melanoma, focusing on phytochemical strategies to overcome treatment challenges and improve survival rates for this lethal skin cancer.

Area of Science:

  • Oncology
  • Dermatology
  • Pharmacology

Background:

  • Metastatic melanoma is a lethal skin cancer with poor survival rates.
  • Immunotherapies and targeted therapies have improved outcomes but face limitations due to multidrug resistance (MDR).
  • Addressing MDR is crucial for enhancing treatment efficacy in metastatic melanoma.

Purpose of the Study:

  • To extensively review the hallmarks of multidrug resistance (MDR) in metastatic melanoma.
  • To highlight strategies for the reversal of MDR.
  • To critically evaluate the clinical translation challenges of phytochemicals for metastatic melanoma and propose solutions.

Main Methods:

  • Comprehensive literature review focusing on MDR mechanisms in melanoma.
  • Analysis of existing and emerging phytochemicals with potential anti-melanoma activity.
  • Evaluation of clinical translation hurdles and research gaps in melanoma treatment.

Main Results:

  • Detailed exposition of MDR hallmarks and effective reversal strategies.
  • Identification of challenges in translating phytochemicals into clinical practice for melanoma.
  • Highlighting research gaps, such as the need for vascularized organ-on-a-chip models for melanoma.

Conclusions:

  • Phytochemicals offer promising avenues for overcoming MDR in metastatic melanoma.
  • Addressing identified research gaps and clinical translation challenges is essential for therapeutic advancement.
  • Novel approaches, including advanced in vitro models, are needed to accelerate phytochemical development for melanoma.

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...

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...

Drugs that Stabilize Microtubules01:15

Drugs that Stabilize Microtubules

Microtubules are dynamic structures that undergo cycles of catastrophe and rescue. The microtubules play a central role in cell division by forming the spindle apparatus for segregating the chromosomes. This makes them ideal targets for regulating dividing cells in tumors and malignant cancer cells. Microtubule stabilizing drugs help stabilize the microtubule formation and promote its polymerization. Paclitaxel was the first microtubule stabilizing agent used as anticancer drug in chemotherapy...

Drugs that Destabilize Microtubules

Microtubules are dynamic structures and can be regulated by microtubule targeting agents (MTAs). Microtubule destabilizing drugs are a class of MTAs that destabilize and prevent microtubules' polymerization. Both natural and synthetic chemicals can be found under this class of drugs. Vincristine and vinblastine, two vinca alkaloids, and colchicine were among the first to be discovered. These drugs can affect cells in various ways, either by inducing a change in cell morphology, preventing...
