Tricellulin, a member of the tight junction-associated MAGUK protein family, preferentially localizes to tricellular junctions in confluent polarized epithelial cell layers and is downregulated during the epithelial-mesenchymal transition. Posttranslational modifications are assumed to play critical roles in the process of downregulation of tricellulin at the protein level. Here, we report that the E3 ubiquitin ligase Itch forms a complex with tricellulin and thereby enhances its ubiquitination. Pull-down assays confirmed a direct interaction between tricellulin and Itch, which is mediated by the Itch WW domain and the N-terminus of tricellulin...

BACKGROUND: Multinucleated Cell Angiohistiocytoma (MCAH) is a rare disease, first described by Smith and Wilson Jones in 1985. Since then, less than 100 cases have been reported in the literature. Clinically it is characterized by papules or plaques arising from a specific anatomical area such as lower extremities, dorsum of the hands and face. Some generalized cases have been reported. MAIN OBSERVATIONS: We report a case of 77-year-old woman who presented with multiple itching...

Atopic dermatitis (AD) is a chronic, recurrent, inflammatory skin disease which predominantly affects children. However, AD may persist until adulthood (persistent AD), or directly start in adults (adult-onset AD). AD often shows a non-flexural rash distribution, and atypical morphologic variants in adults and specific diagnostic criteria are lacking. Moreover, adult AD prevalence as well as detailed data which can characterize persistent vs adult-onset subtype are scant. The aim of this study was to investigate on the main features of adult AD particularly highlighting differences between persistent vs adult-onset form...

Eczema in children is a chronic disabling condition. The impact of this condition on the lives of families is often underestimated by conventional physicians. As a consequence parents may investigate complementary treatment options. Close monitoring by a paediatrician is essential, considering that a variety of adverse effects can occur during the use of complementary treatment. We present a 5-year-old girl with eczema. She visited a Chinese herbalist who prescribed an ointment. The parents noticed that the eczema resolved fast, itching decreased and she was finally sleeping well...

BACKGROUND: Tranilast (N-[3, 4-dimethoxycinnamoyl] anthranilic acid), an antiallergic drug, has been shown to attenuate scar formation possibly through inhibition of transforming growth factor beta 1 activity and consequent suppression of collagen synthesis in fibroblasts. OBJECTIVE: The authors aimed at evaluating the efficacy and safety of tranilast 8% gel in improving the appearance and symptoms of new postcesarean section surgical wounds. METHODS: In this prospective double-blind split-scar study, the authors treated each half scar of 26 women with either tranilast 8% liposomal gel or tranilast-free liposomal gel (placebo)...

Appropriate targets for parathyroid hormone (PTH) in patients with chronic kidney disease (CKD) stages 3-5D are controversial, as are the means by which these targets might be achieved. Secondary hyperparathyroidism is linked to symptoms like bone pain and itch, in addition to less clinically overt issues like bone fragility as well as vascular and soft tissue calcification which may lead to adverse hard endpoints, particularly fracture and death. Recognized therapies for managing a rising PTH include vitamin D analogues, with or without calcimimetic (where available), in addition to management of serum mineral concentrations with diet, binders and dialysis...

BACKGROUND: Polymorphisms of vitamin D receptor (VDR) contribute to the pathogenesis of multiple autoimmune conditions. METHODS: We investigated the incidence of VDR polymorphisms (rs1544410-BsmI; rs7975232-ApaI; rs731236-TaqI) in a group of patients with primary sclerosing cholangitis (PSC, n = 275) and in healthy controls (n = 376). Additionally, correlations of the VDR polymorphisms with clinical and biochemical factors of the disease were analysed. RESULTS: The genotype and allele distributions of these polymorphisms in PSC patients were similar to those observed in controls...

Hippo signaling controls the expression of genes regulating cell proliferation and survival and organ size. The regulation of core components in the Hippo pathway by phosphorylation has been extensively investigated, but the roles of ubiquitination-deubiquitination processes are largely unknown. To identify deubiquitinase(s) that regulates Hippo signaling, we performed unbiased siRNA screening and found that YOD1 controls biological responses mediated by YAP/TAZ. Mechanistically, YOD1 deubiquitinates ITCH, an E3 ligase of LATS, and enhances the stability of ITCH, which leads to reduced levels of LATS and a subsequent increase in the YAP/TAZ level...

Itch is a common symptom in patients with skin and systemic diseases, but the effective treatment is limited. Here, we evaluated the anti-itch effects of the botulinum toxin type A (BoNT/A) using acute and chronic dry skin itch mouse models, which were induced by compound 48/80, chloroquine, and a mixture of acetone-diethylether-water treatment, respectively. Pretreatment of intradermal BoNT/A exerted long-term inhibitory effects on compound 48/80-induced and chloroquine-induced acute itch on days 1, 3, 7, and 14, but not on day 21, in mice...

Stress-induced scratching is an issue in patients with adult atopic dermatitis (AD). Although itching and stress are believed to be intimately related, no objective index is available; therefore, most evaluations are subjective. Using saliva, which is easily collected, we investigated the degree to which AD severity and patient stress levels are reflected in stress proteins in the saliva. Here, we evaluated the severity (Scoring Atopic Dermatitis [SCORAD] score), stress (State-Trait Anxiety Index [STAI] score), personality (Tokyo University Egogram [TEG] II score) and quality of life (Dermatology Life Quality Index [DLQI] score) of 51 patients with AD who were examined in the Department of Dermatology of Shimane University between April and December 2015...

Background.: Patients with end-stage renal disease (ESRD) have a decreased quality of life (QoL), which is attributable in part to ESRD-related hyperparathyroidism (HPT). Both cinacalcet and parathyroidectomy (PTx) are treatments for advanced HPT, but their effects on QoL are unclear. We performed a systematic review to evaluate the impact of cinacalcet and PTx on QoL. Methods.: A systematic literature search was performed using PubMed and EMBASE databases to identify relevant articles...

Recent studies have shown that the chemokine receptor CXCR3 and its ligand CXCL10 in the dorsal root ganglion mediate itch in experimental allergic contact dermatitis (ACD). CXCR3 in the spinal cord also contributes to the maintenance of neuropathic pain. However, whether spinal CXCR3 is involved in acute or chronic itch remains unclear. Here, we report that Cxcr3 (-/-) mice showed normal scratching in acute itch models but reduced scratching in chronic itch models of dry skin and ACD. In contrast, both formalin-induced acute pain and complete Freund's adjuvant-induced chronic inflammatory pain were reduced in Cxcr3 (-/-) mice...

ASPP2 regulates cell polarity and cell-cell adhesion by binding to, and co-localizing with PAR3 at tight junctions. Here we show a novel role of ASPP2 in suppressing gastric cancer (GC) invasiveness. Immunoprecipitation and immunofluorescence analyses showed that ASPP2 promoted the recruitment of PAR3 to cell-cell junctions in GC cells. Diminished expression of ASPP2 and loss of junctional PAR3 localization were significantly associated with diffuse-type histology, deeper invasion depth, positive peritoneal dissemination and worse prognosis in primary GC...

BACKGROUND: Ill-defined chronic symptoms such as itching, burning, urethral discharge, and pelvic pain are not uncommon in male urologic patients. Often, microscopic urinalysis, bacterial cultures, and laboratory testing are non-contributory. We have developed a technique for sperm sedimentation and used the cytologic examination of the sediment routinely in more than 4,000 patients with urologic complaints over the last 5 years. CASE: We present 3 exemplary cases, documenting the diagnostic power of sperm sediment cytology (SSC)...
