Insights

Polyphenols, found in plants, show promise in preventing skin cancer metastasis by influencing key cellular pathways. This review highlights their potential in developing new anti-skin cancer therapies.

Area of Science:

  • Phytochemistry
  • Oncology
  • Molecular Biology

Background:

  • Polyphenols are vital phytochemicals in plants with known anticancer properties.
  • Skin cancer incidence and mortality necessitate research into effective chemopreventive agents.
  • Metastasis is a critical factor in skin cancer progression and patient outcomes.

Purpose of the Study:

  • To review the in vivo chemopreventive effects of purified polyphenols against skin cancer metastasis.
  • To identify specific polyphenols and their mechanisms of action in combating skin cancer.
  • To explore the potential of polyphenols in developing novel therapeutic strategies for skin cancer.

Main Methods:

  • Systematic literature review of studies published between 2000 and August 2019.
  • Inclusion of in vivo mechanistic studies using purified polyphenols.
  • Databases searched included Scopus, PubMed, and Cochrane Library.

Main Results:

  • 34 studies were included, focusing on polyphenols like anthocyanins, EGCG, quercetin, and resveratrol.
  • Polyphenols demonstrated chemopreventive effects against melanoma, a highly metastatic skin cancer.
  • Mechanisms involved modulation of angiogenesis, apoptosis, inflammation, proliferation, and key signaling pathways (e.g., EGFR/MAPK, mTOR/PI3K/Akt).

Conclusions:

  • Polyphenols effectively target multiple signaling pathways involved in skin carcinogenesis and metastasis.
  • Specific polyphenols exhibit significant potential as therapeutic agents against skin cancer.
  • Further research into polyphenols could lead to innovative anti-skin cancer strategies.

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...

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...

Cancer02:18

Cancer

Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.

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...

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...
