BACKGROUND: Connective tissue autoimmune diseases (CTADs) constitute a group of conditions, including rheumatoid arthritis; systemic lupus erythematosus; mixed connective tissue disease; calcinosis, Raynaud's phenomenon, esophageal dysmotility, sclerodactyly, and telangiectasia (CREST) syndrome; scleroderma; dermatomyositis; and Sjögren syndrome. There are few studies on the alterations in filiform papillae in CTAD. Thus, the objective of this work was to determine whether there are changes in the macroscopic and dermoscopic patterns of filiform papillae...

In the present study, we report that camptothecin (CPT) caused irreversible cell cycle arrest at the G2 /M phase, and was associated with decreased levels of cell division cycle 25C (Cdc25C) and increased levels of cyclin B1, p21, and phospho-H3. Interestingly, the reactive oxygen species (ROS) inhibitor, glutathione, decreased CPT-induced G2 /M phase arrest and moderately induced S phase arrest, indicating that the ROS is required for the regulation of CPT-induced G2 /M phase arrest. Furthermore, transient knockdown of nuclear factor-erythroid 2-related factor 2 (Nrf2), in the presence of CPT, increased the ROS' level and further shifted the cell cycle from early S phase to the G2 /M phase, indicating that Nrf2 delayed the S phase in response to CPT...

VP8, the UL47 gene product in bovine herpes virus-1 (BoHV-1), is a major tegument protein, essential for virus replication in vivo The major DNA damage response protein, ataxia telangiectasia mutated (ATM), phosphorylates Nijmegen breakage syndrome (NBS1) and structural maintenance of chromosome-1 (SMC1) proteins during the DNA damage response. VP8 was found to interact with ATM and NBS1 during transfection and BoHV-1 infection. However, VP8 did not interfere with phosphorylation of ATM in transfected or BoHV-1-infected cells...

Inhibition of ataxia-telangiectasia mutated (ATM) during radiotherapy of glioblastoma multiforme (GBM) may improve tumor control by short-circuiting the response to radiation-induced DNA damage. A major impediment for clinical implementation is that current inhibitors have limited CNS bioavailability, thus, the goal was to identify ATM inhibitors (ATMi) with improved CNS penetration. Drug screens and refinement of lead compounds identified AZ31 and AZ32. The compounds were then tested in vivo for efficacy and impact on tumor and healthy brain...

Chromosomal translocations are hallmarks of various types of cancers and leukemias. However, the molecular mechanisms of chromosome translocations remain largely unknown. The ataxia-telangiectasia mutated (ATM) protein, a DNA damage signaling regulator, facilitates DNA repair to prevent chromosome abnormalities. Previously, we showed that ATM deficiency led to the 11q23 chromosome translocation, the most frequent chromosome abnormalities in secondary leukemia. Here, we show that ARP8, a subunit of the INO80 chromatin remodeling complex, is phosphorylated after etoposide treatment...

Objective: Single-nucleotide polymorphisms (SNPs) in the ataxia telangiectasia-mutated gene ATM have been linked with pneumonitis after radiotherapy for lung cancer but have not been evaluated in terms of pulmonary function impairment. Here we investigated potential associations between SNPs in ATM and changes in diffusing capacity of the lung for carbon monoxide (DLCO) in patients with non-small-cell lung cancer (NSCLC) after radiotherapy. Methods: From November 1998 through June 2009, 448 consecutive patients with inoperable primary NSCLC underwent definitive (≥60 Gy) radiotherapy, with or without chemotherapy...

INTRODUCTION: Female genital chronic graft-versus-host disease (cGvHD) is a complication of allogeneic hematopoietic cell transplantation (alloHCT) for blood malignancies. Unattended inflammation and fibrosis in the vulva and vagina may lead to total vaginal stenosis. The course and treatment of genital cGvHD was observed in this population-based prospective study. MATERIAL AND METHODS: Women (n = 41) receiving alloHCT in 2005-2010 were examined before and at 3, 6, 9, 12, 18, 24, 30, and 36 months post-transplant...

Objective Epistaxis is a primary complaint in 90% to 96% of patients with hereditary hemorrhagic telangiectasia (HHT). Numerous surgical and medical treatments aim to decrease the frequency and severity of epistaxis in this patient population. Bevacizumab is a recombinant, humanized monoclonal antibody to vascular endothelial growth factor, an angiogenic factor elevated in HHT. It has been used in several forms to treat epistaxis in HHT but thus far, evidence-based recommendations are limited. Study Design Systematic review with evidence-based recommendations...

Reflex sympathetic dystrophy is a subtype of complex regional pain syndrome, a condition characterized by persistent post-injury extremity pain. Temperature and sweating changes, edema, mobility changes, and a variety of hair, nail, and skin sequelae have been described. Only 23 articles published since 1990 describe dermatologic changes in CRPS. Given this paucity of literature, we present a case to further elucidate cutaneous manifestations of CRPS. Our patient is a 52-year-old Caucasian woman with a 19-year history of reflex sympathetic dystrophy who has presented with several dermatologic complaints...

BACKGROUND: Ataxia-telangiectasia (AT) is a well-known primary immunodeficiency with recurrent sinopulmonary infections and variable abnormalities in both the humoral and cellular immune system. Dysfunctions in immunoglobulin production, reduced number of B cells, and B-cell receptor excision circles copies have been reported. We aimed to understand the immunological mechanisms involving the humoral compartment in AT patients by analysing peripheral blood B cells subsets, B-T lymphocyte cooperation through the expression of CD40 and CD40 ligand (CD40L), and cytokines involved in class-switch recombination production...

Neuroimmunology can be traced back to the XIX century through the descriptions of some of the disease’s models (e.g., multiple sclerosis and Guillain Barret syndrome, amongst others). The diagnostic tools are based in the cerebrospinal fluid (CSF) analysis developed by Quincke or in the development of neuroimmunotherapy with the earlier expression in Pasteur’s vaccine for rabies. Nevertheless, this field, which began to become delineated as an independent research area in the 1940s, has evolved as an innovative and integrative field at the shared edges of neurosciences, immunology, and related clinical and research areas, which are currently becoming a major concern for neuroscience and indeed for all of the scientific community linked to it...

Mosaicism in hemorrhagic telangiectasia (HHT) has been previously identified when testing blood samples of HHT patients. We report the first detection of mosaicism not involving blood of a family proband, and discuss implications for genetic testing algorithms in HHT families. Sanger sequencing and large deletion/duplication analysis in a patient with HHT identified no pathogenic variant in ENG, ACVRL1, or SMAD4. Exome sequencing was then performed on this proband, as well as her affected adult child. A pathogenic ENG variant was detected in the proband's affected child, but not in DNA extracted from peripheral blood of the affected parent/proband...

Evaluation of a pediatric patient presenting with ataxia can be expensive and time consuming. Acute causes tend to have a clear developmental paradigm, but chronic presentations are more likely to be secondary to a genetic disorder, either one that primarily causes ataxia or that presents ataxia as one of a multitude of symptoms. Evaluation should focus on a quick diagnosis for those that have treatment options and for those that require other systemic monitoring. Friedreich ataxia is the most common, and genetic testing can easily confirm the suspicion...

OBJECTIVE: To define the clinical features of myositis patients with anti-PM/Scl-75 and/or anti-PM/Scl-100 autoantibodies at disease onset and during the course of disease and compare them to patients with other forms of myositis. METHODS: In this longitudinal cohort study, the prevalence and severity of clinical features at disease onset and during follow-up were compared between anti-PM/Scl-positive patients and those with the antisynthetase syndrome (AS), dermatomyositis (DM), and immune-mediated necrotizing myopathy (IMNM)...

Ciclopirox olamine (CPX), an off-patent anti-fungal drug, has been found to inhibit the G1 -cyclin dependent kinases partly by increasing the phosphorylation and degradation of Cdc25A. However, little is known about the molecular target(s) of CPX responsible for Cdc25A degradation. Here, we show that CPX induced the degradation of Cdc25A neither by increasing CK1α or decreasing DUB3 expression, nor via activating GSK3β, but through activating Chk1 in rhabdomyosarcoma (Rh30) and breast carcinoma (MDA-MB-231) cells...

REVIEW
Aoife J McCarthy, Runjan Chetty
Smad4 or DPC4 belongs to a family of signal transduction proteins that are phosphorylated and activated by transmembrane serine-threonine receptor kinases in response to transforming growth factor beta (TGF-β) signaling via several pathways. The gene acts as a tumour suppressor gene and inactivation of smad4/DPC4 is best recognised in pancreatic cancer. However, smad4/DPC4 is also mutated in other conditions and cancers such as juvenile polyposis syndrome with and without hereditary haemorrhagic telangiectasia, colorectal and prostate cancers...

BACKGROUND: Ascorbic acid is a substance with confirmed anti-free-radical properties. It triggers the collagen synthesis, has a depigmenting effect and seals blood vessels. All these properties have a significant effect of the skin's appearance. The characteristic traits of capillary skin include telangiectasias as well as erythema, which might consolidate in the future, along with the feeling of burning and increased skin sensitivity. OBJECTIVES: Study and evaluation of selected parameters of capillary skin after the application of 5% vitamin C concentrate throughout the period of 6 weeks with the use of instrumental tests and questionnaires...
