The prevalence and risk of skin cancer have been increasing over past three decades. Two major types of skin cancer observed in humans are melanoma and non-melanoma. Non-melanoma further subdivided into basal cell carcinoma and squamous cell carcinoma. Melanoma arises from melanocyte which locates at the bottom layer of skin epidermis, which primarily protects the skin from being exposed to external factors. Melanoma is less common among all other types of skin cancers but causes higher mortality. Epigenetic regulation associated with the transcriptional activation and inactivation of genes plays a major role in various disease progression including skin cancer...

Repigmentation in vitiligo requires activation, proliferation and migration of the melanoblasts and melanocytes into the depigmented epidermis (1). Cell migration involves modifications of the architecture of cells which requires activation of enzymes that are involved in ECM degradation such as matrix metalloproteinases (MMPs). The significant reduction of their expression in vitiliginous skin has been previously demonstrated (2) and thereby incriminated to share in reducing the migration of melanocytes and their precursors...

Phototherapy has been used for decades in the treatment of many common dermatologic conditions, such as psoriasis, atopic dermatitis, cutaneous T cell lymphoma, vitiligo, and scleroderma, among others. Prior to the commencement of phototherapy, many factors must be considered. For dermatologists, the most important factors include the determination of a patient's skin phototype, concurrent use of photosensitizing agents, and calculation of minimal erythema dose (MED). Though infrequent, the side effects to phototherapy commonly discussed with patients include burns, ocular toxicity, polymorphous light eruption, potential for skin carcinogenesis, and possible worsening of the skin disease...

There has been increasing interest in understanding the role of the human microbiome in skin diseases. Microbiome studies are being utilized in skin cancer research in numerous ways. Commensal bacteria are being studied as a potential tool to judge the biggest environmental risk of skin cancer, ultraviolet (UV) radiation. Owing to the recognized link of skin microbes in the process of inflammation, there have been theories linking commensal bacteria to skin cancer. Viral metagenomics has also provided insight into virus linked forms of skin cancers...

Melanoma is the deadliest form of skin cancer and its incidence is rising, creating a costly and significant clinical problem. Exposure to ultraviolet (UV) radiation, namely UVA (315-400 nm) and UVB (280-315 nm), is a major risk factor for melanoma development. Cumulative UV radiation exposure from sunlight or tanning beds contributes to UV-induced DNA damage, oxidative stress, and inflammation in the skin. A number of factors, including hair color, skin type, genetic background, location, and history of tanning, determine the skin's response to UV radiation...

REVIEW

Ultraviolet radiation (UVR) causes DNA damage in melanocytes by producing photolesions such as cyclobutane pyrimidine dimers and 8-oxo-7-hydrodeoxyguanosine. The production of reactive oxygen species by UVR also induces inflammatory cytokines that, together with the inherent immunosuppressive properties of UVR, propagate carcinogenesis. Nicotinamide (Vitamin B3 ) enhances DNA repair, modulates the inflammatory environment produced by UVR and reduces UV-induced immunosuppression. As nicotinamide reduces the incidence of actinic keratoses and non-melanoma skin cancers in high-risk individuals, and enhances repair of DNA damage in melanocytes, it is a promising agent for the chemoprevention of melanoma in high-risk populations...
