Abstract
The active metabolites of vitamin D3 (D3) and lumisterol (L3) exert a variety of antiaging and photoprotective effects on the skin. These are achieved through immunomodulation and include anti-inflammatory actions, regulation of keratinocytes proliferation, and differentiation programs to build the epidermal barrier necessary for maintaining skin homeostasis. In addition, they induce antioxidative responses, inhibit DNA damage and induce DNA repair mechanisms to attenuate premature skin aging and cancerogenesis. The mechanism of action would involve interaction with multiple nuclear receptors including VDR, AhR, LXR, reverse agonism on RORα and -γ, and nongenomic actions through 1,25D3-MARRS receptor and interaction with the nongenomic binding site of the VDR. Therefore, active forms of vitamin D3 including its canonical (1,25(OH)2D3) and noncanonical (CYP11A1-intitated) D3 derivatives as well as L3 derivatives are promising agents for the prevention, attenuation, or treatment of premature skin aging. They could be administrated orally and/or topically. Other forms of parenteral application of vitamin D3 precursor should be considered to avoid its predominant metabolism to 25(OH)D3 that is not recognized by CYP11A1 enzyme. The efficacy of topically applied vitamin D3 and L3 derivatives needs further clinical evaluation in future trials.

Abstract
The human skin hosts innumerable microorganisms and maintains homeostasis with the local immune system despite the challenges offered by environmental factors such as ultraviolet radiation (UVR). UVR causes cutaneous alterations such as acute (i.e., sunburn) and chronic inflammation, tanning, photoaging, skin cancer, and immune modulation. Phototherapy on the other hand is widely used to treat inflammatory skin diseases such as psoriasis, atopic dermatitis, polymorphic light eruption and graft-versus-host disease (GvHD), as well as neoplastic skin diseases such as cutaneous T cell lymphoma, among others. Previous work has addressed the use of pro- and pre-biotics to protect against UVR through anti-oxidative, anti-inflammatory, anti-aging, anti-carcinogenic and/or pro-and contra-melanogenic properties. Herein, we discuss and share perspectives of the potential benefits of novel treatment strategies using microbes and pro- and pre-biotics as modulators of the skin response to UVR, and how they could act both for protection against UVR-induced skin damage and as enhancers of the UVR-driven therapeutic effects on the skin.

Abstract
Importance Recently, the red hair variants of MC1R were found to contribute differently to pigmentation phenotype in males and females. Objective To investigate the role of these variants in melanoma risk in males and females separately because carriers of the red hair variants of MC1R are at increased risk of melanoma. Design, Setting, and Participants In this hospital-based, case-control study, we evaluated the effect of MC1R and melanoma risk for males and females separately by performing multivariate logistic regression analyses. Main Outcomes and Measures Association of MC1R variants and melanoma risk in males and females. Results A total of 905 females (473 melanoma cases, 432 controls) and 886 males (518 melanoma cases, 368 controls) were included in the analyses. The mean (SD) age of the study population was 59.2 (15.6). In females, carrying any MC1R red hair variants remained an independent risk factor of melanoma in a multivariable analysis (adjusted odds ratio [OR], 2.19 [95% CI, 1.60-2.99]), whereas in males, only signs of actinic skin damage (lentigines on the back [OR, 2.56; 95% CI, 1.47-4.45; P = .001] and the hands [OR, 2.31; 95% CI, 1.24-4.29; P = .008] and wrinkling on the neck [OR, 2.17; 95% CI, 1.23-3.82; P = .007]) and sunburns (OR, 1.65; 95% CI, 1.12-2.42; P = .01) remained significant risk factors. Conclusions and Relevance MC1R variants contribute differently to melanoma risk in males and females. This could be helpful to better classify melanoma risk factors between the sexes.

Abstract
Importance Information on risk factors of subsequent melanomas would be helpful to identify patients at risk after the diagnosis of their first melanomas. Objective To determine risk factors of subsequent melanomas. Design, Setting, and Participants In this retrospective case-control study, 1648 participants with histologically verified cutaneous melanoma diagnosed from January 1, 1968, though March 16, 2015, were recruited from a tertiary referral center as part of the Molecular Markers of Melanoma study. CDKN2A was sequenced in 514 and MC1R in 953 participants. Data were analyzed from March 7, 2008, through March 25, 2015. Main Outcomes and Measures Phenotypic traits and internal and external risk factors for the development of a second, third, or fourth melanoma. Results In total, 1648 patients (53.6% men; mean [SD] age, 54 [15] years) were enrolled, including 1349 with single and 299 with multiple primary melanoma. Mean (SD) age at recruitment was 57 (15) years for the single-melanoma and 62 (14) years for the multiple-melanoma groups. From the internal risk factors, family history (odds ratio [OR], 1.76; 95% CI, 1.22-2.55; P = .006), CDKN2A high-risk mutations (OR, 4.03; 95% CI, 1.28-12.70; P = .02), and high numbers of nevi as a phenotypic risk factor (ORs, 2.23 [95% CI, 1.56-3.28, P < .001] for 20-30 smaller nevi and 2.56 [95% CI, 1.50-4.36; P = .003] for 20-30 larger nevi) were significantly associated with the risk of developing a subsequent primary melanoma using multivariate logistic regression analysis. Nonmelanoma skin cancer (OR, 2.57; 95% CI, 1.84-3.58; P < .001) and signs of actinic skin damage, particularly on the back (ORs, 1.91 [95% CI, 1.12-3.25; P = .04] for freckling and 1.92 [95% CI, 1.29-3.08; P = .007] for solar lentigines), additionally increased risk of a subsequent melanoma. All those factors were also associated with an earlier development of the second melanoma. Patients with 3 melanomas developed their second melanoma earlier than patients with only 2 melanomas (mean [SD] age, 55 [15] years for those with 2 primary melanomas; 52 [15] years for those with 3 primary melanomas). Time spent outdoors, solarium use, outdoor occupation, and hair color had no significant associations in these models. Conclusions and Relevance According to the results of this study, internal factors (family history and genetic variants), number of nevi, and actinic damage on the back are more relevant for the development of subsequent melanomas than skin phototype or hair color. Patients with many nevi were younger at the time of the diagnosis of their first melanoma. This finding could help to identify persons at increased risk of developing multiple primary melanomas.

Abstract
BACKGROUND Risk of melanoma is determined by genetic and exogenous factors. Only a few studies have included both characteristics in a comprehensive multivariable analysis. OBJECTIVES To find determinants of patients at high risk of melanoma in Austria, including phenotype, genotype and lifestyle characteristics in comprehensive analyses. METHODS In total, 1668 patients with melanoma from the M3 case-control study were studied. Overall, 567 participants were sequenced for CDKN2A, 232 for CDK4, 123 for MITF encoding the variant E318K and 964 for MC1R. RESULTS Patients with melanoma with a positive family history (n = 190, 11·6%), multiple primary melanomas (n = 261, 15·7%) and younger age (< 50 years, n = 675, 40·5%) were defined as being at high risk. All other patients with melanoma were defined as the reference group. We found significant differences between those two groups and between the high-risk subgroups (positive family history, multiple primary melanomas and younger age). Pigmentation phenotype was associated with the high-risk group in general (childhood freckling, odds ratio 1·46, P = 0·007; blond/reddish hair colour, odds ratio 1·43, P = 0·011). Patients with a positive family history and patients with early-onset disease were similar regarding both their phenotypic characteristics and external factors. Established high-risk mutations in CDKN2A were found in cases with a positive family history (n = 12) or multiple melanomas (n = 2). Moreover, we found three patients carrying the MITF p.E318K variant, two with a CDK4 variant and seven with nonsynonymous MC1R variants with undescribed biological significance, of which four were predicted as damaging. CONCLUSIONS Austrian patients could represent a reservoir for novel genetic variants. Further investigation of populations in Central and Eastern Europe might reveal more novel and disease-relevant variants.

Kamath S, Miller KA, Cockburn MG. Current Data on Risk Factor Estimates Does Not Explain the Difference in Rates of Melanoma between Hispanics and Non-Hispanic Whites. J Skin Cancer 2016; 2016:2105250.

Abstract
United States Hispanics have seven times lower melanoma incidence rates than non-Hispanic whites (NHW). It is unclear whether this difference can be explained solely by phenotypic risk factors, like darker skin, or whether modifiable risk factors, like sun exposure, also play a role. The purpose of this paper is to summarize what is currently known about melanoma risk factors among Hispanics and NHWs, and whether or not those differences could explain the difference in melanoma incidence. Through literature review, relative risks and prevalence of melanoma risk factors in Hispanics and NHWs were identified and used to calculate the expected rate in Hispanics and rate ratio compared to NHWs. We found that melanoma risk factors either have similar frequency in Hispanics and NHWs (e.g., many large nevi) or are less frequent in Hispanics but do not explain a high proportion of disease variation (e.g., red hair). Considering current knowledge of risk factor prevalence, we found that melanoma incidence rates in the two groups should actually be similar. Sun exposure behavior among Hispanics may contribute to the explanation for the 7-fold difference in melanoma rates. Currently, limited data exist on sun exposure behavior among Hispanics, but possibilities for improving primary prevention by further studying these practices are substantial.

Abstract
CDKN2A is the most prominent familial melanoma gene, with mutations occurring in up to 40% of the families. Numerous mutations in the gene are known, several of them representing regional founder mutations. We sought to determine, for the first time, germline mutations in CDKN2A in Austria to identify novel mutations. In total, 700 individuals (136 patients with a positive family history and 164 with at least two primary melanomas as the high-risk groups; 200 with single primary melanomas; and 200 healthy individuals as the control groups) were Sanger sequenced for CDKN2A exon 1α, 1β, and 2. The 136 patients with affected relatives were also sequenced for CDK4 exon 2. We found the disease-associated mutations p.R24P (8×), p.N71T (1×), p.G101W (1×), and p.V126D (1×) in the group with affected relatives and p.R24P (2×) in the group with several primary melanomas. Furthermore, we discovered four mutations of unknown significance, two of which were novel: p.A34V and c.151-4 G>C, respectively. Computational effect prediction suggested p.A34V as conferring a high risk for melanoma, whereas c.151-4 G>C, although being predicted as a splice site mutation by MutationTaster, could not functionally be confirmed to alter splicing. Moreover, computational effect prediction confirmed accumulation of high-penetrance mutations in high-risk groups, whereas mutations of unknown significance were distributed across all groups. p.R24P is the most common high-risk mutation in Austria. In addition, we discovered two new mutations in Austrian melanoma patients, p.A34V and c.151-4 G>C, respectively.

Abstract
Being the largest and most visible organ of the body and heavily influenced by environmental factors, skin is ideal to study the long-term effects of aging. Throughout our lifetime, we accumulate damage generated by UV radiation. UV causes inflammation, immune changes, physical changes, impaired wound healing and DNA damage that promotes cellular senescence and carcinogenesis. Melanoma is the deadliest form of skin cancer and among the malignancies of highest increasing incidence over the last several decades. Melanoma incidence is directly related to age, with highest rates in individuals over the age of 55 years, making it a clear age-related disease. In this review, we will focus on UV-induced carcinogenesis and photo aging along with natural protective mechanisms that reduce amount of “realized” solar radiation dose and UV-induced injury. We will focus on the theoretical use of forskolin, a plant-derived pharmacologically active compound to protect the skin against UV injury and prevent aging symptoms by up-regulating melanin production. We will discuss its use as a topically-applied root-derived formulation of the Plectranthus barbatus (Coleus forskolii) plant that grows naturally in Asia and that has long been used in various Aryuvedic teas and therapeutic preparations.

Abstract
BACKGROUND Only recently, site-dependent associations of actinic damage with melanoma were identified in our study population. OBJECTIVES To elucidate the diverse aetiologies for actinic damage at different body sites. METHODS We performed multivariate logistic regression analyses to identify independent risk factors for actinic damage on the face, hands and the back in 2112 participants of central European origin. RESULTS For actinic damage on the face, age was the only risk factor that remained consistently significant in a multivariate analysis, whereas actinic damage on the back was predominantly associated with number of sunburns, freckles in childhood, holiday weeks and male sex. Moreover, we identified a particular significance of MC1R variants and dorsal actinic skin damage. CONCLUSIONS The particular effect of MC1R variants and sun exposure during recreational time on dorsal actinic damage indicates that actinic damage on the back is more informative regarding susceptibility to sunlight and past sun exposure associated with melanoma risk.
