Emerging evidence indicates that even subtle changes in the expression of key genes of signaling pathways can have profound effects. MicroRNAs (miRNAs) are masters of subtleness and generally have only mild effects on their target genes. The microRNA miR-31 is one of the major microRNAs in many cutaneous conditions associated with activated keratinocytes such as the hyperproliferative diseases psoriasis, non-melanoma skin cancer, and hair follicle growth. miR-31 is a marker of the hair growth phase, and in our miR-31 transgenic mouse model it impairs the function of keratinocytes, subsequently leading to aberrant proliferation, apoptosis and differentiation that result in altered hair growth, while loss of miR-31 leads to increased hair growth...

BACKGROUND: Non-melanoma skin cancer (NMSC) was officially recognized in 2015 as an occupational disease for outdoor workers in Germany. Together with the enormous socioeconomic impact of NMSC, this has led to the continuous demand of evidence-based prevention. However, studies assessing the perceptions and beliefs along with risk behavior of outdoor workers as an essential prerequisite for prevention are rare. OBJECTIVE: To assess perceptions, beliefs, barriers, risk and preventive behavior towards non-melanoma skin cancer among different outdoor groups as a basis for the development of sustainable prevention programs...

Non-melanoma skin cancers (NMSC) mainly comprise two different entities: basal cell carcinoma (BCC) and squamous cell carcinoma (SCC); beneath these two entities, Merkel cell carcinoma, adnexal tumors, dermatofibrosarcoma protuberans, angiosarcoma, and cutaneous lymphoma belong to NMSC. These rare skin tumors are not the topic of this review. BCC and SCC are the most common cancers diagnosed in humans. The preferred treatment is surgery, which in most cases is curative. Although a high recurrence rate is seen, these cancers rarely metastasize...

Melanoma is the leading cause of death in patients with skin cancer. In the present study, we aimed to prove the functions and molecular mechanisms of lncRNA-GAS5 in melanoma. Herein, we found that the expression of GAS5 was down-regulated in melanoma tissues compared to adjacent normal tissues. GAS5 was significantly associated with distal metastasis and TNM stage in melanoma. Furthermore, we found that GAS5 suppressed melanoma cell proliferation, migration and invasion. Then, we found thatmiR-137 was decreased in melanoma tissues compared to adjacent normal tissues and was correlated with GAS5...

PURPOSE: The most aggressive form of skin cancer is the malignant melanoma. Because of its high metastatic potential the early detection of primary melanoma tumors and metastases using non-invasive PET imaging determines the outcome of the disease. Previous studies have already shown that benzamide derivatives, such as procainamide (PCA) specifically bind to melanin pigment. The aim of this study was to synthesize and investigate the melanin specificity of the novel (68)Ga-labeled NODAGA-PCA molecule in vitro and in vivo using PET techniques...

Cancer risk is increased substantially in adult kidney transplant recipients, but the long-term risk of cancer in childhood recipients is unclear. Using the Australian and New Zealand Dialysis and Transplant Registry, the overall and site-specific incidences of cancer after transplantation in childhood recipients were compared with population-based data using standardized incidence ratios (SIR). Among 1734 childhood recipients (median age 14 years, 57% male, 85% white), 289 (16.7%) developed cancer (196 non-melanoma skin cancers, 143 non-skin cancers) over a median follow-up of 13...

The mainstream treatments for non-melanoma skin cancer (NMSC) include photodynamic therapy (PDT), surgery excision (SE), cryotherapy (CT), imiquimod (IM), radiotherapy (RT), 5-fluorouracil (FU) and vehicle (VE). Our network meta-analysis (NMA) was aimed at evaluating the efficacy and safety of these seven treatments and providing superior ones. After searching the trials from Embase and PubMed and screening with our criteria, we conducted the NMA with software R 3.2.3 and STATA 13.0. Complete lesion response (CLR), complete lesion clearance (CLC), cumulative recurrence probabilities (CRP) and adverse effects (AEs) were considered as outcomes and displayed as odds ratios (ORs) and 95% credible intervals (CrI)...

Purpose: To describe a man with an adherent tick mimicking a melanoma, summarize the salient features of this condition, and review other cases of ticks mistaken for dermatoses. Background: Ticks are obligatory ectoparasites. Disease-causing ticks belong to two families: Ixodidae (hard ticks) and Argasidae (soft ticks). Ticks thrive by consuming blood from animal hosts, and the transfer of infected blood from one host to the next is the method by which ticks spread disease. Materials and methods: The authors describe a man who presented to their dermatology clinic in New York with an unusual black pigmented lesion on the right zygomatic region of his face...

Citral is a natural compound that has shown cytotoxic and antiproliferative effects on breast and hematopoietic cancer cells; however, there are few studies on melanoma cells. Oxidative stress is known to be involved in all stages of melanoma development and is able to modulate intracellular pathways related to cellular proliferation and death. In this study, we hypothesize that citral exerts its cytotoxic effect on melanoma cells by the modulation of cellular oxidative status and/or intracellular signaling...

Metastatic melanoma is the most deadly type of skin cancer. Despite the success of immunotherapy and targeted agents, the majority of patients experience disease recurrence upon treatment and die due to their disease. Long non-coding RNAs (lncRNAs) are a new subclass of non-protein coding RNAs involved in (epigenetic) regulation of cell growth, invasion, and other important cellular functions. Consequently, recent research activities focused on the discovery of these lncRNAs in a broad spectrum of human diseases, especially cancer...

Actinic keratosis (AK) is a cutaneous cancer in situ which develops as a result of excessive exposure to ultraviolet (UV). Toll-like receptor (TLR)7 agonist imiquimod is a topical immune response modifier and is effective for the treatment of non-melanoma skin cancers. Recently, the diagnostic role of the dermatoscope has been reported in the course of treatment of AK. In addition, mast cells are now considered to contribute to both the innate and adaptive immune systems in topical imiquimod therapy. We assessed the effect of imiquimod treatment by dermatoscopic and immunohistochemical findings in 14 patients with a total of 21 AK lesions...

Tobacco smoking is a strong risk factor for cancer, but associations with basal cell carcinomas (BCC) and squamous cell carcinomas (SCC) of the skin have been inconsistent. We prospectively investigated the associations between cigarette smoking and 3-year incidence of first primary BCC or SCC in the QSkin cohort (n=43765). Smoking history was self-reported at baseline; newly diagnosed and surgically treated BCCs and SCCs were ascertained through linkage to the national health insurance scheme and verified by histopathology reports...

BACKGROUND: Gastric cancer is the fourth most common cancer in men and the sixth among women, except for non-melanoma skin tumors, in Brazil. Epidemiological evidences reveal the multifactorial etiology of this cancer, highlighting risk factors such as: infection by the bacterium Helicobacter pylori, advanced age, smoking, chronic alcohol abuse, eating habits and genetic polymorphisms. Considering the context of genetic polymorphisms, there is the absence of the GSTM1 gene. The lack of GSTM1 function to detoxify xenobiotics and promote defense against oxidative stress leads to increased DNA damage, promoting gastric carcinogenesis...
