Malignant melanoma, characterized by its ability to metastasize to other organs, is responsible for 90% of skin cancer mortality. To investigate alterations in the cellular metabolome and lipidome related to melanoma metastasis, gas chromatography-mass spectrometry (GC-MS) and direct infusion-mass spectrometry (DI-MS)-based metabolic and lipidomic profiling were performed on extracts of normal human melanocyte (HEMn-LP), low metastatic melanoma (A375, G361), and highly metastatic melanoma (A2058, SK-MEL-28) cell lines...

Melanoma is the most aggressive type of skin cancer. Melanoma has an extremely poor prognosis because of its high potential for vascular invasion, metastasis and recurrence. The mechanism of melanoma metastasis is not well understood. ATP-binding cassette sub-family B member 5 (ABCB5) plays a key role in melanoma growth. However, it is uncertain what function ABCB5 may exert in melanoma metastasis. In this report, we for the first time demonstrate ABCB5 as a crucial factor that promotes melanoma metastasis...

Inorganic arsenic (iAs) is a carcinogen and could increase the risks of bladder, lung, and skin cancer. Mining and smelting of non-ferrous metals are common occupational arsenic exposures. In this study, 125 individuals working in non-ferrous metal smelting plants were separated into two groups according to urinary total arsenic (TAs) levels: group 1, TAs < 100 μg/g Cr; group 2, TAs ≥ 100 μg/g Cr. Demographic characteristics of participants were obtained by questionnaire interview. Levels of E-cadherin soluble ectodomain fragment (sEcad) and epidermal growth factor (EGF) in workers urine were determined by ELISA test...

The incidence of skin cancer is rising in the U.S., and melanoma, the deadliest form, is increasing disproportionately among young white women. Indoor tanning is a modifiable risk factor for all skin cancers and continues to be used at the highest rates in young white women. Adolescents and young adults report personal appearance-based reasons for using indoor tanning. Previous research has explored the influences on tanning bed use, including individual factors as well as relationships with peers, family, schools, media influences, legislation, and societal beauty norms...

Health literacy, the degree to which individuals have the capacity to obtain, process, and understand health information and services needed to make health decisions, is an essential element for early adults (aged 18-44 years) to make informed decisions about cancer. Low health literacy is one of the social determinants of health associated with cancer-related disparities. Over the past several years, a nonprofit organization, a university, and a cancer center in a major urban environment have developed and implemented health literacy programs within healthcare systems and in the community...

INTRODUCTION: Chronic mental health problems often emerge in young adulthood, when adults begin to develop lifelong health behaviors and access preventive health services. The associations between mental health problems and modifiable cancer risk factors in young adulthood are not well understood. METHODS: In 2016, the authors analyzed 2014 Behavioral Risk Factor Surveillance System data on demographic characteristics, health service access and use, health status, and cancer risk factors (tobacco use, alcohol use, overweight or obesity, physical activity, and sleep) for 90,821 young adults aged 18-39 years with mental health problems (depressive disorder or frequent mental distress) compared to other young adults...

Adolescence and young adulthood, a period essential for determining exposures over the life-course, is an ideal time to intervene to lower cancer risk. This demographic group can be viewed as both the target audience and generator of messages for cancer prevention, such as skin cancer, obesity-, tobacco-, and human papillomavirus-related cancers. The purpose of this paper is to encourage innovative health communications that target youth; youth behavior; and the structural, environmental, and social determinants of youth behavior as critical areas of focus for cancer prevention and disparities reduction...

A significant relationship between arsenic exposure and non-melanoma skin cancer (NMSC) is well known. The toxicity of arsenics which develop NMSC is dependent on their species. Accordingly, total arsenic levels are unreliable for risk assessment of NMSC. However, there are few studies on quantitative exposure assessment of arsenic species in NMSC patients. To validate the contribution of each arsenic species to NMSC, we compared the creatinine-adjusted urinary concentration of arsenic species in NMSC patients and community controls...

Sexual minority males are an at-risk group for developing skin cancer. Elevated rates of skin cancer among this population are thought to be driven by excess indoor tanning; however, motivations to indoor tan among this population are unknown. Theoretically, appearance-based and affect regulation motives may be proximal predictors of increased indoor tanning in this population. The current study tests an integrated biopsychosocial model of indoor tanning behaviors and future intentions among a sample of sexual minority males...

The development of many sporadic cancers is directly initiated by carcinogen exposure. Carcinogens induce malignancies by creating DNA lesions (i.e., adducts) that can result in mutations if left unrepaired. Despite this knowledge, there has been remarkably little investigation into the regulation of susceptibility to acquire DNA lesions. In this study, we present the first quantitative human genome-wide map of DNA lesions induced by ultraviolet (UV) radiation, the ubiquitous carcinogen in sunlight that causes skin cancer...

Alkaptonuria is a rare autosomal recessive metabolic disorder caused by deficiency of homogentisic acid (HGA) oxidase, the only enzyme capable of catabolizing HGA. Deficiency of this enzyme leads to excess HGA which deposits in the connective tissue. We present a case of a 64-year-old woman who was referred to the dermatology clinic for a full body mole check and skin cancer screening. Clinically she had blue/gray pigmentation of the external ear and sclera. Also she had a domed papule on the left cheek with punctate gray pigmentation which was biopsied...

Monoclonal antibodies offer great tools for research. We encountered a potentially useful mouse IgM monoclonal antibody whose antigen is expressed in normal skin but lost in human skin cancer. Because IgM is difficult to work with and the antigen was unknown, we decided to convert the IgM (µ) to IgG (γ) version. After cDNA for the antibody was obtained by RACE PCR, we made a series of molecules with different combinations of IgM and IgG domains. Whereas VH-Cµ1-Cµ2-Cγ3 and VH-Cµ1-Cµ2-Hinge-Cγ2-Cγ3 functionally bound to the antigen, VH-Cγ1-Hinge-Cγ2-Cγ3, VH-Cµ1-Hinge-Cγ2-Cγ3, and VH-Cµ1-Cµ2-Cγ2-Cγ3 did not...

In previous studies, the β-blocker carvedilol inhibited EGF-induced epidermal cell transformation and chemical carcinogen-induced mouse skin hyperplasia. As exposure to ultraviolet (UV) radiation leads to skin cancer, the present study examined whether carvedilol can prevent UV-induced carcinogenesis. Carvedilol absorbs UV like a sunscreen; thus, to separate pharmacological from sunscreen effects, 4-hydroxycarbazole (4-OHC), which absorbs UV to the same degree as carvedilol, served as control. JB6 P+ cells, an established epidermal model for studying tumor promotion, were used for evaluating the effect of carvedilol on UV-induced neoplastic transformation...

OBJECTIVE: Some 25% of women and 8% of men in the United States have experienced childhood sexual abuse (CSA) before the age of 18. For these individuals, healthcare visits and interactions can be retraumatizing due to perceived similarities to past abuse (e.g., pain, undressing, lack of control). However, no prior studies have provided formal qualitative analyses regarding CSA survivors' reactions to cancer treatment. Therefore, our study's objective was to identify key themes pertaining to CSA survivors' cancer treatment experiences...

Though Astragalin (kaempferol-3-glucoside) contained in Paeonia lactiflora and other plants was known to have anti-oxidant, antiinflammatory, and anti-tumor activity, the anti-tumor mechanism of Astragalin has never been reported in melanomas until now. Thus, in the present study, the underlying apoptotic mechanism of Astragalin isolated from Aceriphyllum rossii was elucidated in A375P and SK-MEL-2 melanoma cells. Astragalin exerted cytotoxicity in A375P and SK-MEL-2 cells in a concentration-dependent manner...

The popularity of indoor tanning may be partly attributed to the addictive characteristics of tanning for some individuals. We aimed to determine the association between frequent indoor tanning, which we view as a surrogate for tanning addiction, and food addiction. A total of 67,910 women were included from the Nurses' Health Study II. In 2005, we collected information on indoor tanning during high school/college and age 25-35 years, and calculated the average use of indoor tanning during these periods. Food addiction was defined as ≥3 clinically significant symptoms plus clinically significant impairment or distress, assessed in 2009 using a modified version of the Yale Food Addiction Scale...

BACKGROUND: Heart transplantation (HTx) is the preferred treatment for patients with end-stage heart failure and has been successful for >30 y. The clinical course of recipients at the extreme of age is unknown. We reviewed our experience to determine the overall health and prevalence of Tx-related medical problems for recipients in their ninth decade. METHODS: We reviewed the UCTP experience from 1985 to present to identify patients who survived into their 80s and matched (1:1) with other recipients for gender and age at HTx, but did not survive to ≥80 y...

REVIEW
P Arenberger, M Arenbergerova
Actinic keratosis (AK) is a characteristic skin lesion on skin areas of subjects with mainly phototype I and phototype II, or with specific genetic factors and who are exposed to prolonged ultraviolet radiation. AK may be considered a precursor of in situ squamous cell carcinoma (SCC), a type of non-melanoma skin cancer (NMSC). However, it is still not possible to predict which AK lesions will develop into SCC. Early treatment of AK is therefore recommended. Despite the increasing number of patients with AK developing into SCC, to date, there is still no clear suggestion of therapeutic strategy for AK...
