BACKGROUND: Mucosal healing (MH) is associated with improved clinical outcomes in patients with Crohn's disease (CD) and ulcerative colitis (UC). MH as a target for treatment has been suggested, although there is little pediatric data. The goal of this study was to evaluate MH in clinical practice in pediatric patients with inflammatory bowel disease in clinical remission. METHODS: A retrospective review of electronic health record data was performed on all patients with CD or UC who underwent at least 2 colonoscopies from 2010 through 2016...

In present study, a novel series of fluorine containing 4-(2-pyrimidinylamino)benzamide analogues were designed and synthesized. The hedgehog (Hh) signaling inhibitory activities for these compounds were evaluated by a luciferase reporter method. The preliminary SAR was discussed and many compounds showed potent Hh signaling inhibitory activities. Compound 15h displayed the most potent inhibitory activity, with an IC50 of 0.050nM. This paper finds the introduction of fluorine to the 4-(2-pyrimidinylamino)benzamide scaffold can lead to a novel series of potent Hh signaling pathway inhibitors...

Taste cells undergo constant turnover throughout life; however, the molecular mechanisms governing taste cell generation are not well understood. Using RNA-Seq, we systematically surveyed the transcriptome landscape of taste organoids at different stages of growth. Our data show the staged expression of a variety of genes and identify multiple signaling pathways underlying taste cell differentiation and taste stem/progenitor cell proliferation. For example, transcripts of taste receptors appear only or predominantly in late-stage organoids...

Hedgehog (Hh) regulates the Cubitus interruptus (Ci) transcription factor in Drosophila melanogaster by activating full-length Ci-155 and blocking processing to Ci-75 repressor. However, the interplay between regulation of Ci-155 levels and activity, as well as processing-independent mechanisms that affect Ci-155 levels have not been explored extensively. Here we identified Mago Nashi (Mago) and Y14 core Exon Junction Complex (EJC) proteins, as well as the Srp54 splicing factor as modifiers of Hh pathway activity under sensitized conditions...

The molecular mechanisms of thymosin beta-4 (TB4) involved in regulating hepatic stellate cell (HSC) functions remain unclear. Therefore, we hypothesize that TB4 influences HSC activation through hedgehog (Hh) pathway. HSC functions declined in a TB4 siRNA-treated LX-2. TB4 suppression down-regulated both integrin linked kinase (ILK), an activator of smoothened, and phosphorylated glycogen synthase kinase 3 beta (pGSK-3B), an inactive form of GSK-3B degrading glioblastoma 2 (GLI2), followed by the decreased expression of both smoothened and GLI2...

This study established a method for collecting hand hygiene (HH) performance data based on behavioral drivers (inherent or elective) that can be used by infection preventionists (IPs) to improve practice. Further, we explored the influence that task and setting has on HH behavior. A significant effect was found between task and setting that has implications for improving the usefulness of HH measurement, with positive feedback reported regarding the new measurement method.

To develop appropriate measures to prevent soil contamination in abandoned mining areas, an understanding of the spatial variation of the potentially toxic trace elements (PTEs) in the soil is necessary. For the purpose of effective soil sampling, this study uses hot spot analysis, which calculates a z-score based on the Getis-Ord Gi* statistic to identify a statistically significant hot spot sample. To constitute a statistically significant hot spot, a feature with a high value should also be surrounded by other features with high values...

Cerebral blood flow is an important process for brain functioning and its dysregulation is implicated in multiple neurological disorders. While environmental risk factors have been identified, it remains unclear to what extent the flow is regulated by genetics. Here we performed heritability and genome-wide association analyses of cerebral blood flow in a population-based cohort study. We included 4472 persons free of cortical infarcts who underwent genotyping and phase-contrast magnetic resonance flow imaging (mean age 64...

The deciphering of the hedgehog (Hh) signaling pathway implicated in the tumorigenesis of basal cell carcinoma (BCC), led to the development of targeted drug therapies, e.g. the hedgehog pathway inhibitors (HPI), vismodegib and sonidegib. In the skin, physiologic Hh signaling is activated in growing hair follicles, where it is required for proliferation of the epithelium of hair follicles during morphogenesis and for their postnatal growth. The effects of HPI treatment leading to the regression of BCC and the development of alopecia, underpin the central role of the Hh pathway in BCC formation as well as hair cycling...

Aberrant activation of the Hedgehog (Hh) signaling pathway drives the tumorigenesis of multiple cancers. In this study, we screened a panel of deubiquitinases that may regulate the Hh pathway. We find that deubiquitinase USP48 activates Gli-dependent transcription by stabilizing Gli1 protein. Mechanistically, USP48 interacts with Gli1 and cleaves its ubiquitin off directly. In glioblastoma cells, knockdown of USP48 inhibits cell proliferation and the expression of Gli1's downstream targets, which leads to repressed glioblastoma tumorigenesis...

Understanding the molecular underpinnings of sensitivity to specific therapies will advance the goal of precision medicine in prostate cancer (PCa). We identified 3 patients with metastatic castration-resistant PCa (mCRPC) who achieved an exceptional response to platinum chemotherapy (not first-line treatment for PCa), despite disease progression on prior standard therapies. Using targeted next-generation sequencing on the primary and metastatic tumors, we found that all 3 patients had biallelic inactivation of BRCA2, a tumor suppressor gene critical for homologous DNA repair...

Toward development of a precision medicine framework for metastatic, castration-resistant prostate cancer (mCRPC), we established a multi-institutional clinical sequencing infrastructure to conduct prospective whole-exome and transcriptome sequencing of bone or soft tissue tumor biopsies from a cohort of 150 mCRPC affected individuals. Aberrations of AR, ETS genes, TP53, and PTEN were frequent (40%-60% of cases), with TP53 and AR alterations enriched in mCRPC compared to primary prostate cancer. We identified new genomic alterations in PIK3CA/B, R-spondin, BRAF/RAF1, APC, β-catenin, and ZBTB16/PLZF...

BACKGROUND: Inherited mutations in DNA-repair genes such as BRCA2 are associated with increased risks of lethal prostate cancer. Although the prevalence of germline mutations in DNA-repair genes among men with localized prostate cancer who are unselected for family predisposition is insufficient to warrant routine testing, the frequency of such mutations in patients with metastatic prostate cancer has not been established. METHODS: We recruited 692 men with documented metastatic prostate cancer who were unselected for family history of cancer or age at diagnosis...

The superficial ocular vasculature of the embryonic zebrafish develops in a highly stereotypic manner and hence provides a convenient model for studying molecular mechanisms that regulate vascular patterning. We have used transgenic zebrafish embryos in which all endothelial cells express enhanced Green Fluorescent Protein and small molecule inhibitors to examine the contribution of two signaling pathways, vascular endothelial growth factor (VEGF) and Hedgehog (Hh) pathways, to the development of the superficial system...
