Polycomb repressive complex 2 (PRC2), a H3K27me3 methyltransferase complex, promotes the development of many organs by silencing ectopic transcription program. However, currently little is known about the role of PRC2 in blood and vascular development. In this study, we interrogated the function of embryonic ectoderm development (EED), a core PRC2 component, in both endothelial and hematopoietic tissues by inactivating a floxed murine EED allele with Tie2Cre, which catalyzes recombination in endothelial and hematopoietic lineages...

Inflammation in the perinatal brain caused by maternal or intrauterine fetal infection is now well established as an important contributor to the development of perinatal brain injury. Exposure to inflammatory products can impair perinatal brain development and act as a risk factor for neurological dysfunction, cognitive disorders, cerebral palsy, or preterm birth. Pre-exposure to inflammation significantly exacerbates brain injury caused by hypoxic/ischaemic insult. Tumour necrosis factor (TNF) is a family of cytokines largely involved in inflammation signalling...

In proliferating cells, where most Polycomb repressive complex 2 (PRC2) studies have been performed, gene repression is associated with PRC2 trimethylation of H3K27 (H3K27me3). However, it is uncertain whether PCR2 writing of H3K27me3 is mechanistically required for gene silencing. Here we studied PRC2 function in postnatal mouse cardiomyocytes, where the paucity of cell division obviates bulk H3K27me3 rewriting after each cell cycle. EED (Embryonic Ectoderm Development) inactivation in the postnatal heart (Eed(CKO)) caused lethal dilated cardiomyopathy...

Adenosquamous lung tumours, which are extremely poor prognosis, may result from cellular plasticity. Here, we demonstrate lineage switching of KRAS+ lung adenocarcinomas (ADC) to squamous cell carcinoma (SCC) through deletion of Lkb1 (Stk11) in autochthonous and transplant models. Chromatin analysis reveals loss of H3K27me3 and gain of H3K27ac and H3K4me3 at squamous lineage genes, including Sox2, ΔNp63 and Ngfr. SCC lesions have higher levels of the H3K27 methyltransferase EZH2 than the ADC lesions, but there is a clear lack of the essential Polycomb Repressive Complex 2 (PRC2) subunit EED in the SCC lesions...

The evolution of chromatin-based epigenetic cell memory may be driven not only by the necessity for cells to stably maintain transcription programs, but also by the need to recognize signals and allow plastic responses to environmental stimuli. The mechanistic role of the epigenome in adult postmitotic tissues, however, remains largely unknown. In vertebrates, two variants of the Polycomb repressive complex (PRC2-Ezh2 and PRC2-Ezh1) control gene silencing via methylation of histone H3 on Lys27 (H3K27me). Here we describe a reversible mechanism that involves a novel isoform of Ezh1 (Ezh1β)...

Swallow induced syncope is a rare clinical condition which is thought to result from an abnormal vagal reflex leading to bradycardia and cerebral hypoperfusion. It mostly occurs in patients with organic or functional disorders of the esophagus, and often requires permanent pacemaker implantation, along with treatment of the underlying esophageal pathology. In the following case, we report of a 71-year-old male with achalasia post per oral endoscopic myectomy, who presented with syncope and documented AV-block while eating solid food...

OBJECTIVES: Economic evaluation (EE) is an accepted element of decision making and priority setting in healthcare. As the number of published EEs grows, so does the number of systematic reviews (SRs) of EEs. Although search methodology makes an important contribution to SR quality, search methods in reviews of EEs have not been evaluated in detail. We investigated the resources used to identify studies in recent, published SRs of EEs, and assessed whether the resources reflected recommendations...

BACKGROUND: Frequently cited benefit-cost ratios suggest that interventions to improve neurodevelopment have high economic returns when implemented during pregnancy and early childhood. However, there are many challenges when primary care providers implement these interventions at scale, and it is unclear how many research studies or programmes have examined cost-effectiveness and which methods were used. There are no current scoping or systematic reviews which have assessed economic evaluations of interventions delivered by primary care providers to improve child neurodevelopment...

Concentration of the global population is increasingly occurring in megacities and other developing regions, where access to medicines is increasing more rapidly than waste management systems are implemented. Because freshwater and coastal systems are influenced by wastewater effluent discharges of differential quality, exposures in aquatic systems must be considered. Here, we performed a global scanning assessment of antihistamines (AHs), a common class of medicines, in surface waters and effluents. Antihistamines were identified, literature occurrence and ecotoxicology data on AHs collated, therapeutic hazard values (THVs) calculated, and environmental exposure distributions (EEDs) of AHs compared to ecotoxicity thresholds and drug specific THVs to estimate hazards in surface waters and effluents...

This short review highlights significant changes and recent findings incorporated to varying extent in the WHO 2016 definition of a variety of tumours, including peripheral nerve sheath tumours, meningiomas, mesenchymal non-meningothelial tumours, melanocytic tumours, lymphomas and histiocytic tumours, germ cell tumours and non-neuroendocrine pituitary tumours. Most notable classification changes include: adding "hybrid nerve sheath tumours" to the spectrum of benign nerve sheath tumours; an updated definition of atypical meningioma (WHO grade II), including cases with brain invasion; recognizing dural solitary fibrous tumour (SFT) and haemangiopericytoma (HPC) as a single tumour entity characterized by NAB2 and STAT6 gene fusions for which the term solitary SFT/HPC was chosen; recognizing that pituitary granular cell tumour, spindle cell oncocytoma, and pituicytoma all share nuclear expression of TTF-1, possibly representing a spectrum of a single nosological entity derived from posterior pituitary glial cells...

OBJECTIVE: Given the significant costs of reduced productivity (presenteeism) in comparison to absenteeism, and overall societal costs, presenteeism has a potentially important role to play in economic evaluations. However, these costs are often excluded. The objective of this study is to review applied cost of illness studies and economic evaluations to identify valuation methods used for, and impact of including presenteeism costs in practice. METHODS: A structured systematic review was carried out to explore (i) the extent to which presenteeism has been applied in cost of illness studies and economic evaluations and (ii) the overall impact of including presenteeism on overall costs and outcomes...

OBJECTIVES: Environmental enteric dysfunction (EED) may inhibit growth and development in low- and middle-income countries, but available assessment methodologies limit its study. In rural Bangladesh, we measured EED using the widely-used lactulose mannitol ratio (L:M) test and a panel of intestinal and systemic health biomarkers to evaluate convergence among biomarkers and describe risk factors for EED. METHODS: In 539 18-month-old children finishing participation in a randomized food supplementation trial, serum, stool and urine collected after lactulose and mannitol dosing were analyzed for biomarkers of intestinal absorption, inflammation, permeability and repair, and systemic inflammation...

BACKGROUND AND PURPOSE: Edema may worsen outcome after intracerebral hemorrhage (ICH). We assessed its natural history, factors influencing growth, and association with outcome. METHODS: We estimated edema volumes in ICH patients from the Helsinki ICH study using semiautomated planimetry. We assessed the correlation between edema extension distance (EED) and time from ICH onset, creating an edema growth trajectory model up to 3 weeks. We interpolated expected EED at 72 hours and identified clinical and imaging characteristics associated with faster edema growth...

Aberrant PRC2 activity produces gene repressive epigenetic marks in multiple diseases and led to identification of Ezh2 as a drug target. Recent studies have shown that the epigenetic reader protein EED, associated with Ezh2 in PRC2, has an additional function to stimulate the PRC2 activity after binding to H3K27me3. Optimizing a compound known to block the H3K27me3 site in EED discovered by in-house screening, Novartis scientists have now produced a compound that shows durable tumor regression in a lymphoma xenograft model...

Herein we disclose SAR studies of a series of dimethylamino pyrrolidines which we recently reported as novel inhibitors of the PRC2 complex through disruption of EED/H3K27me3 binding. Modification of the indole and benzyl moieties of screening hit 1 provided analogs with substantially improved binding and cellular activities. This work culminated in the identification of compound 2, our nanomolar proof-of-concept (PoC) inhibitor which provided on-target tumor growth inhibition in a mouse xenograft model. X-ray crystal structures of several inhibitors bound in the EED active-site are also discussed...
