Abstract
BACKGROUND Hidradenitis suppurativa (HS) is a chronic inflammatory disease that is highly correlated with obesity. Haptoglobin serum levels have recently been recognized as an important biomarker linking obesity with chronic inflammation. OBJECTIVE To compare haptoglobin with previously proposed serum biomarkers for the determination of disease severity in HS patients. For this purpose, disease severity of HS patients was determined by a panel of clinical scores as well as several risk factors, such as weight and smoking habits. METHODS A prospective, diagnostic accuracy study was performed at the International Centre for Hidradenitis suppurativa/Acne inversa Bochum (ICH). The study included a total of 263 patients, including 131 who had a confirmed diagnosis of HS in Hurley I (n = 16), II (n = 56) and III (n = 59) HS, and 132 healthy controls. The main outcome was to identify serological inflammatory markers for HS disease severity [severe (III) vs. moderate/mild (II/I)] as assessed by Hurley classification. RESULTS The serum levels of acute phase proteins haptoglobin and CRP, as well as the number of neutrophils in peripheral blood, number of monocytes, the systemic immune-inflammation index and the pan-immune-inflammatory value correlated with disease severity according to established clinical scores (mHSS, SAHS, Hurley, DLQI). HS patients had significantly higher haptologlobin levels compared to healthy controls. Logistic regression analysis revealed haptoglobin as the only independent marker predicting severe HS. CONCLUSION In this prospective study, we discovered that the serum levels of the acute phase protein haptoglobin levels serve as an independent marker of disease severity in HS. While this presents the first study in the context of HS. Thus, the present data not only yield a highly promising serum marker to be further validated.

Abstract
Enhanced glycolysis (Warburg effect) driven by the BRAF oncogene, dysregulated GAPDH expression, and activation of the PI3K/AKT/mTOR signaling pathway may significantly contribute to the resistance-targeted therapy of BRAF-mutated melanomas. Therefore, we aimed to study for the first time the anti-tumor activity of the GAPDH inhibitor GP-2250 in BRAF-mutated melanoma cell lines and benign melanocytes. We employed three melanoma cell lines and one primary melanocyte cell line (Ma-Mel-61a, Ma-Mel-86a, SH-4 and ATCC-PCS-200-013, respectively), which were exposed to different GP-2250 doses. GP-2250's effects on cell proliferation and viability were evaluated by means of the BrdU and MTT assays, respectively. The RealTime-Glo Annexin V Apoptosis and Necrosis Assay was performed for the evaluation of apoptosis and necrosis induction. RT-PCR and western blotting were implemented for the determination of AKT and STAT3 gene and protein expression analyses, respectively. The melanoma cell lines showed a dose-dependent response to GP-2250 during BrDU and MTT testing. The RealTime-Glo Annexin V assay revealed the heterogenous impact of GP-2250 on apoptosis as well as necrosis. With respect to the melanoma cell lines Ma-Mel-86a and SH-4, the responses and dosages were comparable to those used for the MTT viability assay. Using the same dose range of GP-2250 administered to melanoma cells, however, we observed neither the noteworthy apoptosis nor necrosis of GP-2250-treated benign melanocytes. The gene expression profiles in the melanoma cell lines for AKT and STAT3 were heterogenous, whereby AKT as well as STAT3 gene expression were most effectively downregulated using the highest GP-2250 doses. Immunoblotting revealed that there was a time-dependent decrease in protein expression at the highest GP-2250 dose used, whereas a time- as well as dose-dependent AKT decrease was predominantly observed in Ma-Mel-61a. The STAT3 protein expression of Ma-Mel-86a and SH-4 was reduced in a time-dependent pattern at lower and moderate doses. STAT3 expression in Ma-Me-61a was barely altered by GP-2250. In conclusion, GP-2250 has anti-neoplastic effects in BRAF-mutated melanoma cell lines regarding tumor cell viability, proliferation, and apoptosis/necrosis. GP-2250 is able to downregulate the gene and protein expression of aberrant tumorigenic pathways in melanoma cell lines. Since GP-2250 is a GAPDH inhibitor, the substance may be a promising combination therapy for tumors presenting the Warburg effect, such as melanoma.

Abstract
Merkel cell carcinoma (MCC) is a rare, difficult-to-treat skin cancer once immunotherapy has failed. MCC is associated either with the clonal integration of the Merkel cell polyomavirus (MCPyV) or mutagenic UV-radiation. Fumaric acid esters, including dimethyl fumarate (DMF), have been shown to inhibit cell growth in cutaneous melanoma and lymphoma. We aimed to explore the effects of DMF on MCPyV-negative MCC cell lines. Three MCC cell lines (MCC13, MCC14.2, and MCC26) were treated with different doses of DMF. The cytotoxic effects and cell proliferation were assessed by the MTT cytotoxicity assay and BrdU proliferation assay at different time points. A significant reduction in cell viability and proliferation were demonstrated for all the cell lines used, with DMF proving to be effective.

Abstract
PURPOSE To evaluate the protein expression characteristics of genes employed in a recently introduced prognostic gene expression assay for patients with cutaneous melanoma (CM). METHODS We studied 37 patients with CM and 10 with benign (melanocytic) nevi (BN). Immunohistochemistry of primary tumor tissue was performed for eight proteins: COL6A6, DCD, GBP4, KLHL41, KRT9, PIP, SCGB1D2, SCGB2A2. RESULTS The protein expression of most markers investigated was relatively low (e.g., DCD, KRT9, SCGB1D2) and predominantly cytoplasmatic in melanocytes and keratinocytes. COL6A6, GBP4, and KLHL41 expression was significantly enhanced in CM when compared to BN. DCD protein expression was significantly correlated with COL6A6, GBP4, and KLHL41. GBP4 was positively correlated with KLHL41 and inversely correlated with SCGB2B2. The latter was also inversely correlated with serum S100B levels at time of initial diagnosis. The presence of SCGB1D2 expression was significantly associated with ulceration of the primary tumor. KRT9 protein expression was significantly more likely found in acral lentiginous melanoma. The presence of DCD expression was less likely associated with superficial spreading melanoma subtype but significantly associated with non-progressive disease. The absence of SCGB2A2 expression was significantly more often observed in patients who did not progress to stage III or IV. CONCLUSIONS The expression levels observed were relatively low but differed in part with those found in BN. Even though we detected some significant correlations between the protein expression levels and clinical parameters (e.g., CM subtype, course of disease), there was no major concordance with the protective or risk-associated functions of the corresponding genes included in a recently introduced prognostic gene expression assay.

Abstract
Hypertrophic cardiomyopathy (HCM) is a complex myocardial disorder with no well-established disease-modifying therapy so far. Our study aimed to investigate how autophagy, oxidative stress, inflammation, stress signalling pathways, and apoptosis are hallmark of HCM and their contribution to the cardiac dysfunction. Demembranated cardiomyocytes from patients with HCM display increased titin-based stiffness (Fpassive), which was corrected upon antioxidant treatment. Titin as a main determinant of Fpassive was S-glutathionylated and highly ubiquitinated in HCM patients. This was associated with a shift in the balance of reduced and oxidized forms of glutathione (GSH and GSSG, respectively). Both heat shock proteins (HSP27 and α-ß crystalline) were upregulated and S-glutathionylated in HCM. Administration of HSPs in vitro significantly reduced HCM cardiomyocyte stiffness. High levels of the phosphorylated monomeric superoxide anion-generating endothelial nitric oxide synthase (eNOS), decreased nitric oxide (NO) bioavailability, decreased soluble guanylyl cyclase (sGC) activity, and high levels of 3-nitrotyrosine were observed in HCM. Many regulators of signal transduction pathways that are involved in autophagy, apoptosis, cardiac contractility, and growth including the mitogen-activated protein kinase (MAPK), protein kinase B (AKT), glycogen synthase kinase 3ß (GSK-3ß), mammalian target of rapamycin (mTOR), forkhead box O transcription factor (FOXO), c-Jun N-terminal protein kinase (JNK), and extracellular-signal-regulated kinase (ERK1/2) were modified in HCM. The apoptotic factors cathepsin, procaspase 3, procaspase 9 and caspase 12, but not caspase 9, were elevated in HCM hearts and associated with increased proinflammatory cytokines (Interleukin 6 (IL-6), interleukin 18 (IL-18), intercellular cell adhesion molecule-1 (ICAM1), vascular cell adhesion molecule-1 (VCAM1), the Toll-like receptors 2 (TLR2) and the Toll-like receptors 4 (TLR4)) and oxidative stress (3-nitrotyrosine and hydrogen peroxide (H2O2)). Here we reveal stress signalling and impaired PQS as potential mechanisms underlying the HCM phenotype. Our data suggest that reducing oxidative stress can be a viable therapeutic approach to attenuating the severity of cardiac dysfunction in heart failure and potentially in HCM and prevent its progression.

Abstract
BACKGROUND Nodal naevi (NN) represent aggregates of melanocytes within peripheral lymph nodes. NN are relatively often found in patients with malignant melanoma (MM), and may mimic metastatic disease. AIM To study mutation profiles in MM and NN to find out whether NN descend from a primary MM. METHODS Next-generation sequencing was performed on formalin-fixed paraffin-embedded tissue of 26 pairs of primary MM and corresponding NN detected by sentinel lymph node biopsy, and 29 MM-characteristic genes were investigated. RESULTS In this study, 90% of mutations were detected exclusively in either MM or NN, but not both, in the same patient; the percentage of identical NN and MM mutations in the same individual was only 10%. The most frequently discovered shared mutations were a C>G substitution in the CDKN2A gene and in-frame deletion in ARID1A. Oncogenic driver mutations were frequently observed in MM but only rarely in NN. About three-quarters of mutations in both MM and NN were characterized by C>T or G>A substitutions. The detected rate of ultraviolet (UV)-related C>T base changes was comparably high in both primary MM (35%) and NN (32%). CONCLUSIONS Based on our data, it seems that NN descend from previously UV-exposed BRAF wildtype cutaneous melanocytes, rather than from primary MM or arrested progenitor cells.

Abstract
BACKGROUND Hidradenitis suppurativa (HS) is associated with dysregulated immune responses including altered expression of cytokines, chemokines, and antimicrobial peptides and proteins (AMPs). AIMS To evaluate the expression of nucleotide-binding oligomerization domain-containing (NOD)2 and related factors in HS skin samples and keratinocyte cultures. METHODS We performed real-time PCR for NOD2, receptor-interacting serine/threonine-protein kinase (RIP)2, cyclic amine resistance locus (CARL), skin-derived antileukoproteinase (SKALP)/elafin, human β-defensin (hBD)2, LL37, psoriasin and RNAse7 in lesional and nonlesional skin of 19 patients with HS and in keratinocyte cultures [unstimulated, muramyl dipeptide (MDP)-stimulated or Pam2CSK4 (Pam2)-stimulated] from and nonlesional skin. RESULTS We observed significantly elevated mRNA expression for NOD2 (P < 0.01), hBD2 (P = 0.02), RNase7 (P < 0.001), psoriasin (P < 0.01) and SKALP/elafin (P = 0.02) in lesional compared with nonlesional skin. We found a significant correlation between NOD2 mRNA and hBD2 (r = 46; P = 0.04), psoriasin (r = 0.67; P < 0.01) and SKALP/elafin (r = 0.65; P < 0.01). In unstimulated, Pam2-stimulated and MDP-stimulated normal keratinocytes, NOD2, RIP2, CARL and SKALP/elafin expression significantly (P < 0.05) increased from 6 to 48 h, whereas in unstimulated, Pam2-stimulated and MDP-stimulated HS keratinocytes, RIP2, CARL and SKALP/elafin expression significantly (P < 0.05) declined from 6 to 48 h. mRNA expression of NOD2 (unstimulated, Pam2-stimulated, MDP-stimulated), CARL (unstimulated, Pam2-stimulated, MDP-stimulated) and SKALP/elafin (unstimulated, Pam2-stimulated) at 6 h was significantly increased in HS compared with normal keratinocytes. CONCLUSION We have shown for the first time that NOD2 signalling is activated in HS and might contribute to the pathogenesis via induction of AMPs and activation of other pathways such as nuclear factor κB signalling.

Abstract
Simple Summary Merkel cell carcinoma (MCC) is a rare and highly malignant skin cancer with neuroendocrine differentiation. About 80% are Merkel cell polyomavirus (MCPyV) positive. The aim of this work was to immunohistochemically investigate the expression of mismatch repair proteins (MSH2, MSH6, MLH1, and PMS2) in MCC (n = 56). In a second step, tumors with a low expression were tested for microsatellite instability. Microsatellite instability in MCC could have an impact on immune checkpoint inhibitor therapy (ICI) outcome. This study showed a significant association between low expression of mismatch repair proteins and a negative MCPyV status. Microsatellite instability was detected in only one case. Future studies will establish whether this subset of MCC patients respond better to ICI. Abstract We aimed to assess for the first time the mismatch repair (MMR) protein expression in Merkel cell carcinoma (MCC). Immunohistochemistry was performed for MLH1, MSH2, MSH6, and PMS2 on patients’ tumor tissue (n = 56), including neighbored healthy control tissue. In cases with low-level MMR expression (<10th percentile), we performed multiplex PCR in combination with high-resolution capillary electrophoresis in order to confirm microsatellite instability (MSI). Microscopic evaluation revealed a high median expression for all MMR proteins studied (91.6–96.3%). However, six patients (56/10.7%) had low-level MLH1 expression, six (55/10.9%) had low-level MSH2 expression, five (56/8.9%) had low-level MSH6 expression, and six (54/11.1%) had low-level PMS2 expression. Together, we observed nine (56/16.1%) patients who had low-level MMR expression of at least one protein. Of the patients with low-level MMR expression, MSI evaluation was possible in five cases, revealing one case with high-level MSI. In all MMR proteins assessed, low-level expression was significantly (p = 0.0004 to p < 0.0001) associated with a negative Merkel cell polyomavirus (MCPyV) status. However, the expression profiles of the MMR proteins did not correlate with clinical outcome measures such as disease relapse or death (p > 0.05). MCC appears to be a malignancy characterized by low-level MMR rather than completely deficient MMR in a subset of cases, predominantly affecting MCPyV-negative tumors. Future studies will establish whether this subset of MCC patients respond better to immune checkpoint inhibitor therapy.

Abstract
The relevance of Hedgehog signaling in Merkel cell carcinoma has only been addressed by a few studies with conflicting results. Thus, we aimed to establish the expression of Hedgehog signaling molecules in Merkel cell carcinoma to characterize causes of aberrant expression and to correlate these findings with the clinical course of the patients. Immunohistochemistry was performed for Sonic, Indian, Patched 1 (PTCH1) and Smoothened on patients' tumor tissue. Respective mRNA expression was analyzed in 10 Merkel cell carcinoma cell lines using quantitative real-time polymerase chain reaction. PTCH1 sequencing and DNA methylation microarray analyses were carried out on tumor tissues as well as cell lines. PTCH1 immunoreactivity in Merkel cell carcinoma was similar to that of basal cell carcinomas, which both significantly differed from PTCH1 immunoreactivity in healthy skin. Most PTCH1 mutations found were synonymous or without known functional impact. However, on average, the promoter regions of both PTCH1 were hypomethylated independently from PTCH1 gene expression or Merkel cell polyomavirus status. PTCH1 and GLI1/2/3 genes were differently expressed in different cell lines; notably, there was a significant correlation between GLI2 and PTCH1 mRNA expression. Similar to PTCH1 protein expression in patient tissues, PTCH1 gene expression in Merkel cell carcinoma cell lines is highly variable, but due to the similar methylation pattern across Merkel cell carcinoma cell lines, effects other than methylation seem to be the reason for the differential expression and PTCH1 appears to be upregulated by GLI as a classical Hedgehog target gene.

Abstract
BACKGROUND Lefty and Nodal are transforming growth factor β-related proteins, which, beside their role in determination of laterality during embryogenesis, have also been linked with cancer progression. OBJECTIVES Prompted by the observed significant left-sided laterality of Merkel cell carcinoma (MCC), we addressed whether Lefty and Nodal are expressed in MCC and correlated expression patterns with clinical parameters such as MCC laterality and patient outcome. METHODS Expression of Lefty and Nodal in primary MCC was assessed in 29 patients by immunohistochemistry. The histology (H-)score was calculated and correlated with clinical parameters. RESULTS The median (range) H-score of Lefty and Nodal was 17.6 (0-291) and 74.9 (0.7-272), respectively. There was a significant correlation between Lefty expression and Nodal expression (correlation coefficient of 0.60, P = 0.0006). There was no significant correlation between Lefty expression and Nodal expression with either tumour laterality, gender, age, Merkel cell polyomavirus status, disease stage, anatomical localization of primary tumours or disease relapse. On univariate analysis, low Lefty expression and Nodal expression were significantly associated with MCC-specific death (P = 0.010 and P = 0.019, respectively). On univariate analysis, low Lefty expression was the only significant independent predictor for MCC-specific death (P = 0.025) as indicated by an odds ratio of 14 (95% CI: 1.43-137.33). CONCLUSIONS Lefty and Nodal are frequently expressed in MCC, but not correlated with tumour laterality. Importantly, our data suggest that a low level of Lefty expression in primary MCC is a strong predictor of MCC-specific death.

Abstract
BACKGROUND Mid-dermal elastolysis (MDE) is a rare skin condition, characterized by selective loss of elastic fibres in the mid dermis. The pathogenesis of MDE is still unclear. AIM To investigate expression of lysyl oxidase-like 2 (LOXL2) in a reasonable sample of patients with MDE and to search for mutations in LOXL2. METHODS We investigated archived lesional tissue of 13 patients with MDE and skin tissue samples of 10 sex- and age-matched healthy controls (HCs). Gene and protein expression of LOXL2 was investigated using real-time reverse-transcription PCR and immunohistochemistry. Mutation analysis was performed using the Sanger method. RESULTS We observed decreased LOXL2 mRNA expression in lesional skin of patients with MDE (0.48 ± 0.16) compared with healthy skin of the same patients (1.5 ± 0.51) and normal skin of HCs (1.9 ± 0.13). Compared with healthy patient skin (epidermis 2.38 ± 1.6, dermis 1.2 ± 1), LOXL2 protein expression in lesional patient skin (epidermis 1.1 ± 0.7, dermis 0.3 ± 0.45) was significantly decreased (P < 0.04 and P = 0.02, respectively). Mutation analysis of the entire LOXL2 gene could be performed for five patients, all of whom were found to have at least one mutation in the LOXL2 gene. Three of these had a mutation in the promoter region (c.967 G>C, c.1022 C>T, and c.1025 G>A, respectively), and one of them also had a mutation in the splice region of intron 11/exon 12 (IVS11-1 G>A). Of the remaining two patients, one had a mutation in exon 3 (T1391), and the other had a mutation in exon 11 (C663Y). CONCLUSIONS Our present data suggest that decreased elastin renewal due to LOXL2 mutations and consecutive reduced LOXL2 expression contribute to the pathogenesis of MDE.

Abstract
BACKGROUND The pathogenesis of hidradenitis suppurativa (HS), with its complex inflammatory network, is still elusive. Imbalances in DNA methylation can lead to genome destabilization and have been assumed to play a role in inflammatory diseases. Global DNA methylation and hydroxymethylation have not been studied in HS yet. OBJECTIVE We conducted this study to investigate the global DNA methylation and hydroxymethylation status in lesional and perilesional HS skin compared to healthy controls. METHODS Immunohistochemical analysis was performed for 5-methylcytosine (5-mC) and 5-hydroxymethylcytosine (5-hmC) in 30 lesional and 30 corresponding healthy-appearing perilesional HS tissue samples. We included 30 healthy subjects as an interindividual control group. RESULTS 5-hmC levels were significantly lower in healthy-appearing perilesional (p < 0.0001) and lesional HS skin (p < 0.0001) when compared to healthy controls. There was no significant difference between lesional HS skin and perilesional HS skin regarding 5-hmC levels (p = 0.6654). In contrast to 5-hmC, 5-mC staining showed no significant changes between the 3 groups. Univariate analysis revealed no significant association between patients' characteristics, disease severity, and the levels of 5-mC and 5-hmC. CONCLUSION Our findings indicate that imbalances in DNA hydroxymethylation may play a role in the pathogenesis of HS rather than DNA methylation. Further studies are warranted to investigate the significance of DNA hydroxymethylation and the regulating enzymes in HS in order to advance our knowledge of the inflammatory network in this disease.

Abstract
BACKGROUND Bullous pemphigoid (BP) is the most common autoimmune blistering disease, and is associated with autoantibodies to the hemidesmosomal BP autoantigens BPAG1 and BPAG2. AIM We aimed to investigate the significance of T regulatory cells and other lymphocyte subsets in patients with BP. METHODS In total, 31 inpatients with BP were treated with systemic prednisolone in a tapered dose regimen, while 28 healthy individuals matched for age and sex served as the healthy control (HC) group., Blood samples were taken at baseline and after treatment, and levels of inducer/helper and suppressor/cytotoxic T lymphocytes, B lymphocytes, natural killer cells, CD4+CD25++CD127- cells were assessed by flow cytometry, while CD4, CD8, and FOXP3 positivity were assessed by immunohistochemistry, and FOXP3 mRNA was assessed by reverse transcription (RT)-PCR. RESULTS Flow cytometry showed that numbers of CD8+ and CD4+CD25++CD127- cells were significantly increased, while the number of CD4+ cells and the CD4/CD8 ratio were significantly decreased at baseline and after therapy in patients with BP compared with HCs. Immunohistology revealed that CD4+, CD8+ and FOXP3+ cells were significantly increased at baseline and post-treatment in patients with BP compared with HCs. FOXP3 mRNA levels were significantly increased in the blood of patients with BP compared with HCs. CONCLUSION These results indicate that increased numbers of CD8+, CD4+CD25++CD127- cells and FOXP3+ cells may play a pathogenetic role during the course of BP.

Abstract
BACKGROUND A variety of cancers are associated with the expression of the oncogenic miR-17-92 cluster (Oncomir-1) and tumor suppressor miR-143-5p/miR-145-5p. Epidermal skin cancer has not been investigated for the expression of miR-17-92 and miR-143-145 clusters, despite being extensively studied regarding global microRNA profiles. The goal of this study was to investigate the expression and possible correlation of expression of miR17-92 and miR-143-145 cluster members in epidermal skin cancer. METHODS We evaluated punch biopsies from patients with cutaneous squamous cell carcinoma (cSCC, n=15) and basal cell carcinoma (BCC, n=16), along with control specimens from non-lesional epidermal skin (n=16). Expression levels of the miR17-92 cluster (including miR-17-5p, miR-17-3p, miR-18a-3p, miR-18a-5p, miR-19a-3p, miR-19a-5p, miR-19b-3p, miR-19b-1-5p, miR-20a-3p, miR-20a-5p, miR-92a-3p, and miR-92a-5p) and the tumor-suppressive cluster miR-143-145 (including miR-143-5p and miR-145-5p) were detected by quantitative real-time reverse transcriptase polymerase chain reaction. RESULTS We noted a highly significant increased expression of the miR-17-92 members miR-17-5p, miR-18a-5p, miR19a-3p, and miR-19b-3p and tumor suppressor miR-143-5p (p<0.01) in cSCC. miR-145-5p had a significantly decreased expression (p<0.05) for in BCC. A correlation analysis revealed multiple correlating miRNA-pairs within and between the investigated clusters. CONCLUSION This study marks the first evidence for the participation of members of the miR-17-92 cluster in cSCC and miR-143-145 cluster in BCC.

Abstract
Since the discovery of microRNAs (miRNAs) there have been performed several studies showing perturbations in the expression of miRNAs and the miRNA expression machinery in cutaneous melanoma. Dicer, a pivotal cytosolic enzyme of miRNA maturation has shown to be affected by both somatic and germline mutations in a variety of cancers. Recent studies have shown that recurrent somatic mutations of Dicer frequently affect the metal-ion-binding sites D1709 and D1705 of its RNase IIIb domain, therefore called hot spot mutations. The present study investigates metal-ion-binding sites D1709 and D1705 of the Dicer RNase IIIb domain in cutaneous melanomas and melanoma metastasis by Sanger sequencing. All investigated samples showed wildtype sequence and no single mutation was detected. The miRNA processing enzyme Dicer of melanoma and melanoma metastasis does not appear to be affected by mutation in the metal-ion-binding sites D1709 and D1705 of its RNase IIIb domain.

Abstract
BACKGROUND The inflammatory pathogenesis behind the debilitating chronic inflammatory skin disorder hidradenitis suppurativa (HS) is poorly understood. Deregulation of microRNAs (miRNAs) may contribute to the pathogenesis and chronic inflammation in autoimmune and inflammatory diseases. However, there are no data on the expression or function of miRNAs in HS. OBJECTIVE To evaluate expression of the miRNA key regulators Drosha, Drosha co-factor DGRC8, Dicer and Exportin-5 in the inflammatory microenvironment of HS. METHODS Specimens were harvested from lesional HS skin (n=18), adjacent healthy-appearing HS skin (n=7), lesional psoriatic skin (n=10), and healthy subjects (n=10). To evaluate the quantitative real-time RT-PCR data of Drosha and Dicer a subset of skin samples were studied by immunohistochemistry. RESULTS Drosha and DGRC8 were significantly downregulated in healthy-appearing perilesional skin from HS patients compared to healthy controls. There were no significant differences in Drosha, DGRC8 and Exportin-5 expression between lesional HS and lesional psoriatic skin. Notably, Dicer expression levels were not dysregulated in psoriatic skin. LIMITATIONS Small sample size and descriptive study design. CONCLUSIONS The miRNA key regulators were significantly dysregulated in HS lesions compared to healthy skin. Drosha and DGRC8 are altered in the initial, subclinical inflammatory process in healthy-appearing perilesional skin of HS patients prior to the first visible clinical manifestations. Dicer and Exportin-5 may contribute to the later inflammatory process with visible HS lesions.

Abstract
BACKGROUND Epigenetics refers to functionally relevant changes in the genome other than those of DNA sequence that can lead to changes in gene expression or cellular phenotype. There is evidence that epigenetics is relevant in the pathogenesis of autoimmune diseases such as vulvar lichen sclerosus (VLS), as well as in cancer, including cutaneous squamous cell carcinoma, which is frequently associated with VLS. OBJECTIVES To study the global methylation and hydroxymethylation status in healthy controls and VLS lesions before and after long-term ultraviolet (UV)A1 treatment. METHODS We studied 12 controls and 10 patients with VLS who were treated with medium-dose UVA1 four times weekly for 3 months. Immunohistochemistry and mutation analyses (polymerase chain reaction) were performed for 5-methylcytosine (5mC), 5-hydroxymethylcytosine (5hmC), isocitrate dehydrogenases (IDHs) and the ten-eleven translocation (TET)2 enzyme. RESULTS After 3 months of treatment, 5mC was significantly increased in VLS compared with baseline and controls. However, compared with controls 5hmC levels were significantly reduced in baseline VLS, but normalized after UVA1 treatment. Compared with controls, IDH1 expression was significantly higher in both treated and baseline VLS. By contrast, IDH2 levels were significantly reduced in baseline VLS compared with controls and UVA1-treated VLS. However, gene sequencing of the IDH1, IDH2 and TET2 genes did not reveal evidence of mutations. CONCLUSIONS VLS is associated with altered expression of IDH enzymes and aberrant hydroxymethylation, indicating an epigenetic background for the pathogenesis of VLS. UVA1 phototherapy may cause normalization of 5hmC patterns, but also global DNA hypermethylation in VLS lesions, raising concerns with respect to an increased risk of photocarcinogenesis.

Abstract
BACKGROUND Polymorphic light eruption (PLE) is considered to be an autoimmune-mediated skin condition in which the normal ultraviolet (UV)-induced local immunosuppression appears to be absent, leading to recognition of photoinduced autoantigens and subsequent inflammation. OBJECTIVES To investigate T regulatory cells (Tregs) and related immunoregulatory factors in PLE lesions and controls. METHODS Skin biopsies were performed in 13 patients with UVA1-challenged PLE, 12 female patients with chronic discoid lupus erythematosus (CDLE) and 11 healthy controls who had exposure to UVA1. Immunohistochemistry and four-colour immunofluorescence studies were performed. RESULTS Patients with CDLE and UVA1-exposed controls showed significantly decreased epidermal immunoreactivity for CD1a compared with patients with PLE (P = 0·0001). Four-colour immunofluorescence revealed a median percentage of CD4+CD25+FOXP3+ Tregs of 7·6% (range 3·7-13·6%) in PLE, a median of 11·7% (range 9·5-13·9%) in CDLE and a median of 3·4% (range 0-6·8%) in controls. Compared with UVA1-exposed controls, PLE and CDLE lesions showed significantly decreased transforming growth factor (TGF)-β1 immunoreactivity in the epidermis (P = 0·0003). In PLE lesions, we observed significantly decreased interleukin (IL)-10 expression compared with CDLE (P = 0·022). In the dermis, receptor activator of nuclear factor-κB ligand (RANKL) expression was increased in UVA1-exposed controls compared with PLE and CDLE (P = 0·018). CONCLUSIONS Similar to CDLE lesions, UVA1-challenged PLE lesions display an altered immunoregulatory network, as indicated by decreased epidermal or dermal expression of TGF-β1, IL-10 and RANKL, and a relatively low number of Tregs, particularly when compared with other inflammatory skin conditions reported in the literature.

Abstract
The quantitative real-time polymerase chain reaction (qRT-PCR) is a valuable and well-proven technique used to investigate the expression level of multiple components of the microRNA (miRNA) maturation machinery. Here, we describe how to determine the messenger RNA expression levels of components of the miRNA machinery starting from the isolation of the RNA from a tissue biopsy to performance of the qRT-PCR.

Abstract
Perturbations in microRNA (miRNA) expression profiles have been reported for cutaneous malignant melanoma (CMM) predominantly when examined in cell lines. Despite the rapidly growing number of newly discovered human miRNA sequences, the availability of up-to-date miRNA expression profiles for clinical samples of primary cutaneous malignant melanoma (PCMM), cutaneous malignant melanoma metastases (CMMM), and benign melanocytic nevi (BMN) is limited. Specimens excised from the center of tumors (lesional) from patients with PCMM (n=9), CMMM (n=4), or BMN (n=8) were obtained during surgery. An exploratory microarray analysis was performed by miRNA expression profiling based on Agilent platform screening for 1205 human miRNAs. The results from the microarray analysis were validated by TaqMan quantitative real-time polymerase chain reaction. In addition to several miRNAs previously known to be associated with CMM, 19 unidentified miRNA candidates were found to be dysregulated in CMM patient samples. Among the 19 novel miRNA candidates, the genes hsa-miR-22, hsa-miR-130b, hsa-miR-146b-5p, hsa-miR-223, hsa-miR-301a, hsa-miR-484, hsa-miR-663, hsa-miR-720, hsa-miR-1260, hsa-miR-1274a, hsa-miR-1274b, hsa-miR-3663-3p, hsa-miR-4281, and hsa-miR-4286 were upregulated, and the genes hsa-miR-24-1*, hsa-miR-26a, hsa-miR-4291, hsa-miR-4317, and hsa-miR-4324 were downregulated. The results of this study partially confirm previous CMM miRNA profiling studies identifying miRNAs that are dysregulated in CMM. However, we report several novel miRNA candidates in CMM tumors; these miRNA sequences require further validation and functional analysis to evaluate whether they play a role in the pathogenesis of CMM.

Abstract
Background Acne inversa is a chronic, suppurative relapsing inflammatory skin disease that primarily affects the axillae, perineum and inframammary regions. Evidence suggests that the innate immune system is involved in the pathogenesis of acne inversa. Objective To investigate the role of the innate immune system in acne inversa. Methods Skin biopsies were obtained from inflammatory skin lesions (n=17) and from non-lesional skin (intraindividual control, n=17) of patients with acne inversa. Additional skin lesions were taken from patients with chronic venous leg ulcers (interindividual control, n=5). Quantitative real-time reverse transcription-polymerase chain reaction was used to determine the mRNA levels of antimicrobial peptides and proteins (AMPs), including human β-defensin (hBD)-1, hBD-2 and hBD-3, LL-37 (cathelicidin) and Ribonuclease 7 (RNase 7). mRNA levels were also determined for inflammatory and anti-inflammatory cytokines, including tumor necrosis factor-alpha (TNF-α), matrix metalloproteinase-1 (MMP1), interleukin (IL)-1β, IL-6, IL-8 and IL-10. Results The mRNA levels of hBD-2, LL-37, IL-1β, IL-6, IL-8, IL-10 and MMP1 were significantly higher in acne inversa lesions compared to non-lesional skin (p<0.05). A significant positive correlation expression was observed between hBD-2 mRNA expression and LL-37 (ρ=0.53, p=0.03), and between hBD-2 and RNAse 7 (ρ=0.68, p=0.006). When compared to the chronic venous leg ulcer lesions, acne inversa lesions showed a significantly higher expression of RNase 7 mRNA, while IL-1 β, IL-6, IL-8, TNF-α and MMP1 mRNA expression was significantly higher in the chronic venous leg ulcer lesions (p<0.05). Conclusion The AMP, cytokine milieu and tissue proteases in acne inversa lesions differ significantly from non-lesional skin and chronic venous leg ulcers. The positively correlating up-regulation of AMPs in acne inversa indicates an important role of the innate immune system in the pathogenesis of this disorder.

Abstract
Although several studies have shown a dysregulation of microRNA (miRNA) expression profiles in cutaneous melanoma, there has been little research on the miRNA machinery itself. In this study, we investigated the mRNA expression profiles of different miRNA machinery components in primary cutaneous malignant melanoma (PCMM), cutaneous malignant melanoma metastases (CMMM) and benign melanocytic nevi (BMN). Patients with PCMM (n = 7), CMMM (n = 6) and BMN (n = 7) were included in the study. Punch biopsies were harvested from the centers of tumors (lesional) and from BMN (control). In contrast to previous reports exploring specific clusters of miRNAs in PCMM, the present study investigates mRNA expression levels of Dicer, Drosha, Exp5, DGCR8 and the RISC components PACT, argonaute-1, argonaute-2, TARBP1, TARBP2, MTDH and SND1, which were detected by TaqMan real-time reverse transcription polymerase chain reaction (RT-PCR). Argonaute-1, TARBP2 and SND1 expression levels were significantly higher in BMN compared to PCMM (p < 0.05). TARBP2 expression levels were significantly higher in CMMM compared to PCMM (p < 0.05). SND1 expression levels were significantly higher in CMMM compared to PCMM and BMN (p < 0.05). Dicer, Drosha, DGCR8, Exp5, argonaute-2, PACT, TARBP1 and MTDH expression levels showed no significant differences within groups (p > 0.05). The results of this study show that the miRNA machinery components argonaute-1, TARBP2 and SND1 are dysregulated in PCMM and CMMM compared to BMN and may play a role in the process of malignant transformation.

Abstract
BACKGROUND MicroRNAs (miRNAs) are a novel class of short RNAs that are capable epigenetically regulating gene expression in eukaryotes. MicroRNAs have been shown to be dysregulated in a variety of cancers. The data on miRNA expression in cutaneous squamous cell carcinoma (cSCC) are very limited, and microarray-based miRNA expression profiles of cSCC have not yet been determined. OBJECTIVE To describe differentially expressed miRNAs in cSCC. METHODS Seven patients with cSCC were enrolled in the present study. Tumor biopsies (n=7) were taken from the center of each tumor. Adjacent healthy skin (n=7) was biopsied as a control (intraindividual control). miRNA expression profiles of all specimens were detected by microarray miRNA expression profiling based on miRBAse 16 scanning for 1205 potential human miRNA target sequences. The microarray results were confirmed by TaqMan quantitative real-time polymerase chain reaction (qRT-PCR). RESULTS Non-stringent filtering with a non-adjusted p ≤ 0.05 revealed thirteen up-regulated and eighteen down-regulated miRNAs. Non-stringent filtering with a non-adjusted p ≤ 0.01 revealed three up-regulated (hsa-miR-135b, hsa-miR-424 and hsa-miR-766) and six down-regulated (hsa-miR-30a*, hsa-miR-378, hsa-miR-145, hsa-miR-140-3p, hsa-miR-30a and hsa-miR-26a) miRNAs in cSCC. CONCLUSION This study reveals differentially expressed miRNAs that may play a role in the molecular pathogenesis of cSCC and that are excellent candidates for further validation and functional analysis.

Abstract
Clear cell sarcoma (CCS) of tendons and aponeuroses is an aggressive neoplasm that is characterized by a pathognomonic translocation, t(12;22)(q13;q12), resulting in an EWSR1-ATF1 chimeric gene. We report for the first time a female patient with CCS exhibiting both EWSR1-ATF1 fusion transcripts and hereditary homozygous point mutations in introns 11 and 16 of the KIT gene. Her parents and two brothers each had heterozygous point mutations in intron 11 or intron 16 of the KIT gene. The functional significance of these germline deep intronic point mutations and their relationship to the pathogenesis of CCS are unclear. Future studies investigating KIT intron mutations in a larger cohort of CCS patients are warranted.

Abstract
The microprocessor complex mediates intranuclear biogenesis of precursor microRNAs from the primary microRNA transcript. Extranuclear, mature microRNAs are incorporated into the RNA-induced silencing complex (RISC) before interaction with complementary target mRNA leads to transcriptional repression or cleavage. In this study, we investigated the expression profiles of the microprocessor complex subunit DiGeorge syndrome critical region gene 8 (DGCR8) and the RISC components argonaute-1 (AGO1), argonaute-2 (AGO2), as well as double-stranded RNA-binding proteins PACT, TARBP1, and TARBP2 in epithelial skin cancer and its premalignant stage. Patients with premalignant actinic keratoses (AK, n = 6), basal cell carcinomas (BCC, n = 15), and squamous cell carcinomas (SCC, n = 7) were included in the study. Punch biopsies were harvested from the center of the tumors (lesional), from healthy skin sites (intraindividual controls), and from healthy skin sites in a healthy control group (n = 16; interindividual control). The DGCR8, AGO1, AGO2, PACT, TARBP1, and TARBP2 mRNA expression levels were detected by quantitative real-time reverse transcriptase polymerase chain reaction. The DGCR8, AGO1, AGO2, PACT, and TARBP1 expression levels were significantly higher in the AK, BCC, and SCC groups than the healthy controls (P < 0.05). There was no significant difference in the TARBP2 expression levels between groups (P > 0.05). This study indicates that major components of the miRNA pathway, such as the microprocessor complex and RISC, are dysregulated in epithelial skin cancer.

Abstract
BACKGROUND The histopathology of lichen sclerosus (LS) suggests abnormalities in extracellular matrix (ECM) composition. OBJECTIVES We aimed to investigate the expression pattern of ECM proteins and related growths factors and Smad signal transducers in LS as compared with healthy skin. METHODS To assess the expression of decorin, biglycan, versican, perlecan, fibronectin, dermatopontin, extracellular matrix protein 1 (ECM-1), matrix metalloproteinase 1, tissue inhibitor of metalloproteinase 1, connective tissue growth factor (CTGF), transforming growth factor β1, and Smad-3 protein, real-time RT-PCR and immunohistochemistry were performed on skin specimens obtained from the genital region of healthy subjects (n = 10) as well as LS patients (n = 26). RESULTS Median mRNA as well as mean protein expression of biglycan, versican, fibronectin, and ECM-1 was significantly higher in LS when compared with healthy controls. Both mRNA and protein CTGF expression observed in LS was significantly higher than in controls. CTGF mRNA expression significantly correlated with mRNA expression of biglycan, versican and fibronectin. CONCLUSIONS Expression of ECM proteins (e.g. proteoglycans, ECM-1) and CTGF is altered in LS. TGF-ß/Smad-3 independent up-regulation of CTGF may induce accumulation of ECM proteins and maintain fibrosis in chronic LS.

Abstract
Recent papers highlight the role of dysregulated expression of antimicrobial peptides and proteins (AMPs) in the pathogenesis of psoriasis. Etanercept, a blocker of the pro-inflammatory cytokine tumour necrosis factor-α (TNF-α), is effective in the treatment of psoriasis. We aimed to evaluate the expression profiles of AMPs in psoriatic skin before and after a 6-week course of etanercept therapy. We included 12 psoriasis patients who underwent medium-dose etanercept treatment for 6weeks. At baseline and at the end of therapy immunohistochemistry from lesional skin was performed for psoriasin, LL-37, and human ß-defensin 2 (hBD-2). After 6-week treatment, the modified psoriasis area and severity index significantly decreased from 37.5±5.9 to 14±13.4. Lesional immunoreactivity scores of psoriasin, LL-37, and hBD-2 also significantly decreased after a 6-week course of etanercept. We have demonstrated that etanercept-induced improvement of psoriasic lesions is associated with a significant decline of AMP protein expression.
