Yes-associated protein (Yap) is a major effector of the Hippo pathway that regulates cell proliferation and differentiation during development and restricts tissue growth in adult animals. However, its role in synapse formation remains poorly understood. In this study, we characterized Yap's role in the formation of neuromuscular junction (NMJ). In HSA-Yap(-/-) mice where Yap was mutated specifically in muscle cells, AChR clusters were smaller and were distributed in a broader region in the middle of muscle fibers, suggesting that muscle Yap is necessary for the size and location of AChR clusters...

Vitiligo is the most common cutaneous depigmentation disorder worldwide, yet little is known about specific risk factors for disease development. Utilizing data from the Nurses' Health Study (NHS), a prospective cohort study of 51,337 white women, we examined the associations between (1) pigmentary traits and (2) reactions to sun exposure and risk of incident vitiligo. NHS participants responded to a question about clinician-diagnosed vitiligo and year of diagnosis (2001 or before, 2002-2005, 2006-2009, 2010-2011, or 2012+)...

REVIEW
A C Green, C M Olsen
Cutaneous squamous cell carcinoma (SCC) is a common cancer in white populations and its disease burden is often substantially underestimated. SCC occurs more often in men than women and increases dramatically with age; those affected often develop multiple primaries over time, which increases the burden. The main external cause is solar ultraviolet radiation (UVR), with immunosuppression being the other established risk factor, shown by the high SCC rates in organ transplant recipients. Sunbed use and certain genetic disorders and medical conditions are also associated with SCC, while associations with human papillomavirus infection and high bodyweight are not established...

RATIONALE: The early detection of recurrent differentiated thyroid carcinoma (DTC) cells in postsurgery DTC patients relies on the sensitivity of measuring both the level of thyroglobulin (Tg) and 131-iodine distribution on a whole-body scan (WBS). Recent studies have defined patients who subsequently have no evidence of disease as those who have a stimulated Tg level <1 ng/mL with no other radiological or clinical evidence of disease. PATIENT CONCERNS: A woman patient with solid variant papillary thyroid carcinoma (SVPTC) had undergone twice thyroidectomy with lymph node dissection and radioactive therapy...

BACKGROUND: The drug discovery and development pipeline is a long and arduous process that inevitably hampers rapid drug development. Therefore, strategies to improve the efficiency of drug development are urgently needed to enable effective drugs to enter the clinic. Precision medicine has demonstrated that genetic features of cancer cells can be used for predicting drug response, and emerging evidence suggest that gene-drug connections could be predicted more accurately by exploring the cumulative effects of many genes simultaneously...

Liver fibrosis is a consequence of chronic liver disease, causing morbidity and mortality. Interleukin-33 (IL-33) is a critical mediator of inflammation, which may be involved in the development of liver fibrosis. Here, we investigated the role of IL-33 in human patients and experimental bile-duct ligation (BDL)-induced fibrosis in mice. We report increased hepatic IL-33 expression in the murine BDL model of fibrosis and in surgical samples obtained from patients with liver fibrosis. Liver injury, inflammatory cell infiltration and fibrosis were reduced in the absence of the IL-33/ST2 receptor, and the activation of hepatic stellate cells (HSCs) was decreased in ST2-deficient mice...

Communities of zooplankton can be adversely affected by contamination resulting from human activities. Yet understanding the influence of water quality on zooplankton under field-conditions is hindered by traditional labor-intensive approaches that are prone to incomplete or uncertain taxonomic determinations. Here, for the first time, an eco-genomic approach, based on genetic diversity in the mitochondrial cytochrome c oxidase I (COI) region of DNA of zooplankton was used to develop a site-specific, water quality criterion (WQC) for ammonia (NH3)...

BACKGROUND: Mechanical ventilation via automated in-hospital ventilators is quite common during cardiopulmonary resuscitation. It is not known whether different inspiratory triggering sensitivity settings of ordinary ventilators have different effects on actual ventilation, gas exchange and hemodynamics during resuscitation. METHODS: 18 pigs enrolled in this study were anaesthetized and intubated. Continuous chest compressions and mechanical ventilation (volume-controlled mode, 100% O2, respiratory rate 10/min, and tidal volumes 10ml/kg) were performed after 3 minutes of ventricular fibrillation...

Given that increased thermogenesis in white adipose tissue, also known as browning, promotes energy expenditure, significant efforts have been invested to determine the molecular factors involved in this process. Here we show that HOXC10, a homeobox domain-containing transcription factor expressed in subcutaneous white adipose tissue, is a suppressor of genes involved in browning white adipose tissue. Ectopic expression of HOXC10 in adipocytes suppresses brown fat genes, whereas the depletion of HOXC10 in adipocytes and myoblasts increases the expression of brown fat genes...

Cardiac hypertrophy is one of the major risk factors of cardiovascular morbidity and mortality. Autophagy is acknowledged to be an important mechanism regulating cardiac hypertrophy. Sestrin 1, a downstream target gene of p53, has been proven to regulate autophagy. However, the role of Sestrin 1 in cardiac hypertrophy remains unknown. Our study showed that Sestrin 1 mRNA and protein expression declined in pressure overload cardiac hypertrophy and phenylephrine (PE)-induced cardiac hypertrophy. Knockdown of Sestrin 1 by RNAi deteriorated PE-induced cardiac hypertrophy, whereas the overexpression of Sestrin 1 by adenovirus transfection blunted hypertrophy...

Natural and artificial tanning have become very popular in Western culture, yet at the same time, there is still a psychodermatology concern for this activity. Not much has been examined with the psychological aspects of tanning and sunscreen use. The purpose of this study is to examine the psychosocial effects associated with sun protection, natural, and artificial tanning among individuals 18 years old or older visiting the University of Miami Dermatology Outpatient Clinic. We distributed a survey on tanning and sunscreen use to 150 dermatology outpatients, hospital employees, and hospital visitors for three weeks during June/July 2015 asking about how often they tan, use sunscreen, and how they feel about this topic...

Enterovirus 96 (EV-96) is a recently described member of the species Enterovirus C and is associated with paralysis and myelitis. In this study, using metagenomic sequencing, we identified a new enterovirus 96 strain (EV-96-SZ/GD/CHN/2014) as the sole pathogen causing hand, foot, and mouth disease (HFMD). A genomic comparison showed that EV-96-SZ/GD/CHN/2014 is most similar to the EV-96-05517 strain (85% identity), which has also been detected in Guangdong Province. This is the first time that metagenomic sequencing has been used to identify an EV-96 strain shown to be associated with HFMD...

Phytocystatins (PhyCys) comprise a group of inhibitors for cysteine proteinases in plants. They play a wide range of important roles in regulating endogenous processes and protecting plants against various environmental stresses, but the underlying mechanisms remain largely unknown. Here, we detailed the biological functions of MpCYS4, a member of cystatin genes isolated from Malus prunifolia. This gene was activated under water deficit, heat (40°C), exogenous abscisic acid (ABA), or methyl viologen (MV) (Tan et al...
