Insights

Phytochemicals show promise in preventing and treating metastatic melanoma, a deadly cancer. Research explores their mechanisms, bioavailability, and structure-activity relationships for melanoma management.

Area of Science:

  • Oncology
  • Pharmacology
  • Natural Product Chemistry

Background:

  • Melanoma is a deadly skin cancer, responsible for approximately 80% of skin cancer-related deaths, primarily due to its metastatic potential.
  • The prognosis for metastatic melanoma is poor, with a median survival of only six months, even with advanced treatments.
  • Key oncogenes BRAF and NRAS are frequently mutated in melanoma, driving critical signaling pathways involved in cancer progression and therapeutic resistance.

Purpose of the Study:

  • To review the preventive and therapeutic potential of various phytochemicals in managing metastatic melanoma.
  • To discuss the mechanisms of action, bioavailability, and structure-activity relationships of selected phytochemicals for melanoma treatment.
  • To highlight the role of phytochemicals as potentially low-toxicity, cost-effective adjuncts in melanoma management.

Main Methods:

  • Review of existing literature on phytochemicals and their effects on melanoma.
  • Analysis of cell culture and animal studies elucidating the cellular and molecular mechanisms of phytochemical action.
  • Examination of data on the bioavailability and structure-activity relationships of promising phytochemicals.

Main Results:

  • Numerous phytochemicals, including fisetin, epigallocatechin-3-gallate, resveratrol, and curcumin, demonstrate significant potential in preclinical studies.
  • These compounds exhibit diverse mechanisms against melanoma, impacting cell proliferation, survival, epithelial-to-mesenchymal transition, and metastasis.
  • Evidence suggests phytochemicals can overcome therapeutic resistance pathways activated in malignant melanoma.

Conclusions:

  • Phytochemicals represent a promising class of compounds for the prevention and treatment of metastatic melanoma.
  • Further research into their bioavailability and structure-activity relationships is crucial for optimizing their therapeutic application.
  • These natural compounds offer a potentially safe and accessible complementary approach to conventional melanoma therapies.

Cancer Prevention02:59

Cancer Prevention

Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

Skin Cancer01:30

Skin Cancer

Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Pigmentation01:19

Pigmentation

The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

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...

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...
