Failures of neural tube closure are common and serious birth defects, yet we have a poor understanding of the interaction of genetics and cell biology during neural tube closure. Additionally, mutations that cause neural tube defects (NTDs) tend to affect anterior or posterior regions of the neural tube but rarely both, indicating a regional specificity to NTD genetics. To better understand the regional specificity of cell behaviors during neural tube closure, we analyzed the dynamic localization of actin and N-cadherin via high-resolution tissue-level time-lapse microscopy during Xenopus neural tube closure. To investigate the regionality of gene function, we generated mosaic mutations in shroom3, a key regulator or neural tube closure This approach elucidates new differences between cell behaviors during cranial/anterior and spinal/posterior neural tube closure, provides mechanistic insight into the function of shroom3 and demonstrates the ability of tissue-level imaging and analysis to generate cell-biological mechanistic insights into neural tube closure.

Sleep duration was associated with symptom burden and poorer survival and IL-2 was found to mediate the association between sleep and survival. Screening and treatment of sleep problems in patients diagnosed with cancer are warranted.

To determine the contribution of defective splicing in Autism Spectrum Disorders (ASD), the most common neurodevelopmental disorder, a high throughput Massively Parallel Splicing Assay (MaPSY) was employed and identified 42 exonic splicing mutants out of 725 coding de novo variants discovered in the sequencing of ASD families. A redesign of the minigene constructs in MaPSY revealed that upstream exons with strong 5’ splice sites increase the magnitude of skipping phenotypes observed in downstream exons. Select hits were validated by RT-PCR and amplicon sequencing in patient cell lines. Exonic splicing mutants were enriched in probands relative to unaffected siblings -especially synonymous variants (7.5% vs 3.5%, respectively). Of the 26 genes disrupted by exonic splicing mutations, 6 were in known ASD genes and 3 were in paralogs of known ASD genes. Of particular interest was a synonymous variant in TNRC6C - an ASD gene paralog with interactions with other ASD genes. Clinical records of 3 ASD patients with TNRC6C variant revealed respiratory issues consistent with phenotypes observed in TNRC6 depleted mice. Overall, this study highlights the need for splicing analysis in determining variant pathogenicity, especially as it relates to ASD.

Background: Engaging patients and other stakeholders is a key tenet of patient-centered research, but can be challenging to implement.  Objectives: To determine the feasibility of using patient narratives for informing comparative effectiveness research and engaging patients in the research process.Research Design: Cross-sectional study.Participants: The first 153 participants to share a story using the MyPaTH Story Booth protocol were, on average, aged 51 (18.8). Most were white (79%) or African American (13%) and well-educated.Measures: Participants self-categorized their narratives according to the sort of health experience(s) described (e.g., diagnosis, doctor/patient communication), the anatomic locations of health problems discussed and the type of disorder or condition addressed. They also reported on whether they were interested in engaging in clinical research as a participant or stakeholder and their satisfaction with the study processes.Results: The archived narratives addressed a wide range of health experiences of relevance to clinical researchers, most often medical treatment (82%), communication with healthcare team members (81%), diagnosis (64%), symptoms (61%), healthcare access (60%) and health decision-making (60%). Health problems related to diverse anatomic locations were addressed. Health conditions such as mental health concerns (35%), infections (23%) and cancers (20%) were often discussed. Among participants, 63% expressed interest in learning of opportunities for stakeholder engagement in research related to their stories. Ninety seven percent were very satisfied or satisfied with the MyPaTH Story Booth process. Conclusions: The narrative archive represents a unique resource for researchers interested in developing and carrying out patient-centered research projects to improve health or healthcare.
