Skin Therapy Letter
|September 10, 2017
Summary
Nicotinamide, a form of vitamin B3, shows promise in treating skin conditions and preventing skin cancer by enhancing DNA repair and immune function. It supports cellular energy production essential for these protective processes.
Area of Science:
- Dermatology
- Biochemistry
- Oncology
Background:
- Nicotinamide (vitamin B3) is recognized for its therapeutic potential in various dermatological conditions like acne, rosacea, and atopic dermatitis.
- Emerging research highlights nicotinamide's role as a chemopreventive agent against skin cancer, utilizing both topical and oral formulations.
- Its anti-carcinogenic effects are linked to improved DNA repair mechanisms and mitigation of UV-induced immunosuppression, crucial factors in pre-malignant lesion progression.
Purpose of the Study:
- To explore the multifaceted roles of nicotinamide in dermatological health and skin cancer chemoprevention.
- To elucidate the biochemical pathways through which nicotinamide exerts its protective effects on skin.
- To understand nicotinamide's contribution to cellular energy metabolism and DNA repair.
Main Methods:
- Review of recent scientific literature on nicotinamide's dermatological and chemopreventive applications.
- Analysis of studies investigating the molecular mechanisms of nicotinamide's action, including DNA repair and immune modulation.
- Examination of nicotinamide's role as a precursor to nicotinamide adenine dinucleotide (NAD) and its impact on cellular energy production (ATP synthesis).
Main Results:
- Nicotinamide demonstrates efficacy in treating inflammatory skin conditions such as acne, rosacea, and atopic dermatitis.
- Evidence supports nicotinamide's chemopreventive capabilities against skin cancer, attributed to enhanced DNA repair and prevention of UV-induced immunosuppression.
- Nicotinamide serves as a vital precursor for NAD, a key coenzyme in ATP synthesis, thereby supporting energy-dependent cellular functions including DNA repair.
Conclusions:
- Nicotinamide possesses significant therapeutic and chemopreventive potential in dermatology.
- Its mechanisms of action involve bolstering DNA repair, modulating immune responses to UV radiation, and supporting cellular energy metabolism.
- Further research into nicotinamide's applications may lead to novel strategies for managing skin diseases and preventing skin cancer.

6.3K
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...

01:23Role of Skin in Vitamin D Synthesis
8.3K
The skin plays a crucial role in the synthesis of vitamin D, a vital nutrient for various physiological processes in the body. Vitamin D is unique because it can be synthesized in the skin through a series of chemical reactions triggered by exposure to ultraviolet B (UVB) radiation from sunlight.
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin...

8.2K
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.

01:19Pigmentation
4.7K
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...

Vitamins, derived from the Latin word for life, are essential organic substances required in small quantities for optimal growth and overall well-being. Unlike other organic nutrients, vitamins don't act as sources of energy or building materials but rather facilitate these nutrients' utilization by the body. Vitamins are predominantly coenzymes, assisting enzymes in specific chemical actions, like the oxidation of glucose for energy involving B vitamins. Most vitamins are not produced...

DNA Distortion and Damage
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...
