    Cutaneous malignant melanoma incidences analyzed worldwide by sex, age, and skin type over personal Ultraviolet-B dose shows no role for sunburn but implies one for Vitamin D3.
    Dermatoendocrinol 2017 14;9(1):e1267077. Epub 2016 Dec 14.
    Marquette University, Department of Mathematics, Statistics, and Computer Science, Milwaukee, WI, USA.
    Because the incidence of cutaneous malignant melanoma (CMM) was reported to increase with increasing terrestrial UVR (290-400 nm) doses in the US back in 1975 and a recent publication showed no association exists with UVR exposure at all, we set out to fully elucidate the role of UVR in CMM. To achieve this goal, we analyzed the CMM incidences over latitude and estimated the average personal UVR dose in the US and numerous countries (> 50) on 5 continents around the world. Using data from the International Agency for Research on Cancer in 2005, we performed worldwide analysis of CMM over UVR dose by sex, age group (0-14, 15-29, 30-49, 50-69, 70-85+) and Fitzpatrick skin types I-VI.

    CK1α ablation in keratinocytes induces p53-dependent, sunburn-protective skin hyperpigmentation.
    Proc Natl Acad Sci U S A 2017 Sep 6;114(38):E8035-E8044. Epub 2017 Sep 6.
    The Lautenberg Center for Immunology and Cancer Research, Institute for Medical Research Israel-Canada, Hebrew University-Hadassah Medical School, Jerusalem 91120, Israel
    Casein kinase 1α (CK1α), a component of the β-catenin destruction complex, is a critical regulator of Wnt signaling; its ablation induces both Wnt and p53 activation. To characterize the role of CK1α (encoded by Csnk1a1) in skin physiology, we crossed mice harboring floxed Csnk1a1 with mice expressing K14-Cre-ER(T2) to generate mice in which tamoxifen induces the deletion of Csnk1a1 exclusively in keratinocytes [single-knockout (SKO) mice]. As expected, CK1α loss was accompanied by β-catenin and p53 stabilization, with the preferential induction of p53 target genes, but phenotypically most striking was hyperpigmentation of the skin, importantly without tumorigenesis, for at least 9 mo after Csnk1a1 ablation.

    Sunburn and ambient temperature.
    Br J Dermatol 2017 Sep 2. Epub 2017 Sep 2.
    Newcastle University - Dermatological Sciences, Newcastle, NE2 4HH, United Kingdom.
    On days during the summer months when high temperatures are expected, weather forecasters frequently warn about the dangers of UV and high UV indices. It is not surprising, therefore, that it is a common belief that high ambient air temperatures are a major risk factor for burning. Although the UV index is generally higher on cloudless, hot days compared with cloudy, cool days, reliance should not be placed on ambient temperature alone as a guide to the need for sun protection.

    Oxidized Polymeric Phenolics: Could They Be Considered Photoprotectors?
    J Agric Food Chem 2017 Sep 28;65(36):7843-7846. Epub 2017 Aug 28.
    Dipartimento di Scienze Agrarie e Ambientali (DISAA), Università degli Studi di Milano , via Celoria 2, 20133 Milano, Italy.
    Photooxidative sunburn is the consequence of photosystem overexcitations. It results in tissue color changes as a result of chlorophyll degradation and accumulation of oxidized polymeric phenolics (OPPs), resulting from scavenging of reactive oxygen species (ROS). From a productive point of view, OPPs should be considered as damages, decreasing the economical and esthetical values of plants and crops. Read More

    Am J Med Genet A 2017 Sep 8;173(9):2511-2516. Epub 2017 Jul 8.
    Laboratory of Genetic Instability and Oncogenesis, UMR8200 CNRS, Gustave Roussy, Université Paris-Sud, Villejuif, France.
    We describe the characterization of Xeroderma Pigmentosum variant (XPV) in a young Caucasian patient with phototype I, who exhibited a high sensitivity to sunburn and multiple cutaneous tumors at the age of 15 years. Two novel mutations in the POLH gene, which encodes the translesion DNA polymerase η, with loss of function due to two independent exon skippings, are reported to be associated as a compound heterozygous state in the patient. Western blot analysis performed on proteins from dermal fibroblasts derived from the patient and analysis of the mutation spectrum on immunoglobulin genes produced during the somatic hypermutation process in his memory B cells, show the total absence of translesion polymerase η activity in the patient.

    Ultraviolet radiation accelerates NRas-mutant melanomagenesis: A cooperative effect blocked by sunscreen.
    Pigment Cell Melanoma Res 2017 Sep 4;30(5):477-487. Epub 2017 Jul 4.
    Department of Cancer Biology and Genetics, Biomedical Research Tower, The Ohio State University, Columbus, OH, USA.
    To mitigate melanoma risk, sunscreen use is widely advocated; yet, the ability of sunscreens to prevent melanoma remains controversial. Here, we test the tenet that sunscreens limit melanoma risk by blocking ultraviolet radiation (UV)-induced DNA damage using murine models that recapitulate the genetics and spontaneous evolution of human melanoma. We find that a single, non-erythematous dose of UV dramatically accelerates melanoma onset and increases tumor multiplicity in mice carrying an endogenous, melanocyte-specific NRas(61R) allele.

    CXCL1 Inhibition Regulates UVB-Induced Skin Inflammation and Tumorigenesis in Xpa-Deficient Mice.
    J Invest Dermatol 2017 Sep 17;137(9):1975-1983. Epub 2017 May 17.
    Division of Dermatology, Department of Internal Related, Kobe University Graduate School of Medicine, Kobe, Japan. Electronic address:
    Xeroderma pigmentosum complementation group A is a hereditary disease characterized by early onset of skin cancers and freckle-like pigmented maculae in sun-exposed sites. Although the etiology of the predisposition to UVR-induced skin tumors in xeroderma pigmentosum complementation group A is well investigated as a repair deficiency in UVR-induced DNA damage, the mechanism of exaggerated sunburn in patients with xeroderma pigmentosum complementation group A and whether UVR-induced inflammation relates to a skin tumor-prone phenotype remains to be elucidated. Using gene profiling of xeroderma pigmentosum complementation group A model mice, Xpa-deficient mice, we found that expression of CXCL1 in the skin and blood of Xpa-deficient mice increased significantly after UVB exposure over even a limited area compared with that of wild-type mice.

    Recognizing Latinos' range of skin pigment and phototypes to enhance skin cancer prevention.
    Pigment Cell Melanoma Res 2017 Sep 4;30(5):488-492. Epub 2017 Jul 4.
    Stellenbosch Institute for Advanced Study, The Pennsylvania State University, University Park, PA, USA.
    Latinos in the United States may have the mistaken assumption that their natural pigmentation protects them from developing skin cancer that, effectively, serves as a barrier to Latinos receiving education in primary and secondary prevention of skin cancer. Latino adults of Mexican or Puerto Rican heritage attending community health fairs in the greater Chicago area responded to a culturally informed and sensitive measure for sunburn and tan, which was previously adapted to capture skin irritation with tenderness from the sun occurring in darker skin types (n = 350). By self-reported responses and spectrophotometry assessment of constitutive pigmentation, adapted Fitzpatrick skin types (FST) ranged from skin type I-IV in the Mexican American participants and from II to V in the Puerto Rican participants.
