Noonan syndrome (NS), the most common RASopathy, is caused by mutations affecting signaling through RAS and the MAPK cascade. Recently, genome scanning has discovered novel genes implicated in NS, whose function in RAS-MAPK signaling remains obscure, suggesting the existence of unrecognized circuits contributing to signal modulation in this pathway. Among these genes, LZTR1 encodes a functionally poorly characterized member of the BTB/POZ protein superfamily. Read More

Background: Catabolism and tumor-specific therapy lead to reduced nutrient intake and weight loss in cancer patients. Maintaining a specific individualized diet can be challenging for the patient as the nutritional counseling options are limited. Monitoring of nutrient intake and frequent feedback are, however, vital for successful nutritional therapy because they support the patient's compliance and realization of dietary therapeutic goals.

The nuclear factor I (NFI) family of transcription factors play an important role in normal development of multiple organs. Three NFI family members are highly expressed in the brain, and deletions or sequence variants in two of these, NFIA and NFIX, have been associated with intellectual disability (ID) and brain malformations. NFIB, however, has not previously been implicated in human disease. Read More

Scope: Diet is amongst the most crucial factors contributing to the multistep process of carcinogenesis. The role of exogenous microRNAs (miRNAs) is still debatable. In this proof-of-principle work, the presence of miRNAs in a variety of foods, its stability to processing, and detectability in GI mucosa and feces are studied and the effect of short-term diet on human- or plant-derived miRNAs in feces and blood is examined.

Background And Aims: Incision of the cricopharyngeal (CP) muscle with flexible endoscopy is an important approach for Zenker diverticulum (ZD) repair with symptomatic resolution in approximately 90% of cases, but recurrence has been reported in up to 20%. We report our experience with a new endoscopic myectomy of the CP muscle and compare the outcome with conventional myotomy of ZD.
Methods: Our retrospective study included all patients with ZD who underwent endoscopic repair between August 1, 2014, and July 31, 2017. Read More

The RASopathies are a complex group of conditions regarding phenotype and genetic etiology. The ClinGen RASopathy Expert Panel (RAS EP) assessed published and other publicly available evidence supporting the association of 19 genes with RASopathy conditions. Using the semiquantitative literature curation method developed by the ClinGen Gene Curation Working Group, evidence for each gene was curated and scored for Noonan syndrome (NS), Costello syndrome, cardiofaciocutaneous syndrome, NS with multiple lentigines, and Noonan-like syndrome with loose anagen hair.

This report summarizes and highlights the fifth International RASopathies Symposium: When Development and Cancer Intersect, held in Orlando, Florida in July 2017. The RASopathies comprise a recognizable pattern of malformation syndromes that are caused by germ line mutations in genes that encode components of the RAS/mitogen-activated protein kinase (MAPK) pathway. Because of their common underlying pathogenetic etiology, there is significant overlap in their phenotypic features, which includes craniofacial dysmorphology, cardiac, cutaneous, musculoskeletal, gastrointestinal and ocular abnormalities, neurological and neurocognitive issues, and a predisposition to cancer.

Endoscopic cricopharyngeal myotomy has been demonstrated to be a safe and efficacious procedure with favorable outcomes for the treatment of cricopharyngeal dysfunction with or without Zenker diverticulum. It is a less invasive approach with decreased morbidity compared with the open approach and minimal reported complications. Peroral endoscopic pyloromyotomy is a novel technique for the treatment of gastroparesis. Read More

The preimplantation mouse embryo is a simple self-contained system, making it an excellent model to discover how mammalian cells function in real time and in vivo. Work over the last decade has revealed some key morphogenetic mechanisms that drive early development, yielding rudimentary instructions for the generation of a mammalian embryo. Here, we review the instructions revealed thus far, and then discuss remaining challenges to discover upstream factors controlling cell fate determination, test the role of mechanisms based on biological noise, and take advantage of recent technological developments to advance the spatial and temporal resolution of our current understanding.

No efficient treatment exists for nephrotic syndrome (NS), a frequent cause of chronic kidney disease. Here we show mutations in six different genes (MAGI2, TNS2, DLC1, CDK20, ITSN1, ITSN2) as causing NS in 17 families with partially treatment-sensitive NS (pTSNS). These proteins interact and we delineate their roles in Rho-like small GTPase (RLSG) activity, and demonstrate deficiency for mutants of pTSNS patients. Read More

In psychology as elsewhere, the main statistical inference strategy to establish empirical effects is null-hypothesis significance testing (NHST). The recent failure to replicate allegedly well-established NHST-results, however, implies that such results lack sufficient statistical power, and thus feature unacceptably high error-rates. Using data-simulation to estimate the error-rates of NHST-results, we advocate the (RPS) as a superior methodology. Read More
