Notch engagement by Jag1 clusters on the nanoscale suggests a force-independent mode of activation

ABSTRACT: The Notch signaling pathway is a cell-cell communication system with fundamental roles in embryonic development and the nervous system, including neural stem cell proliferation and differentiation. To investigate the multivalency effect of ligands on the activation of the Notch receptor, we treated iPSc-derived neuroepithelial stem-like (lt-NES) cells with different Jag1 nanopatterns on DNA origami nanostructures.

CUT&RUN experiment at four time points in HEK293T and hESC cells, assessing the time-resolved response of β-catenin genomic occupancy upon Wnt signaling activation

Project description:Wnt/β-catenin signaling is a highly organized biochemical cascade that triggers a gene expression program in the signal-receiving cell. The Wnt/β-catenin-driven transcriptional response is involved in virtually all cellular processes during development, homeostasis, and its deregulation causes human disease. However, outstanding questions remain unanswered. A first question concerns cell-specificity: how this response is integrated into lineage-specific choices is still unknown. A second question concerns time: it is not known whether β-catenin associates with its targets simultaneously or in a time-dependent fashion. For instance, while TCF/LEF and other components of the Wnt transcriptional complex are constitutively associated with the chromatin, it is β-catenin arrival, upon Wnt induction, that launches target genes transcription. Therefore, discovering the dynamics of the genome-wide β-catenin binding pattern is required to unambiguously define the direct targets of Wnt signaling To address these questions, we realized a time-resolved atlas of β-catenin genome-wide occupancy in two human cell types, human embryonic kidney cells 293T (HEK293T) and human embryonic stem cells (hESCs). To this end, we treated HEK293T and hESCs with the GSK3 inhibitor/Wnt activator CHIR99021 (10 mM) for 3 days, and assessed β-catenin binding via CUT&RUN-LoV-U (Zambanini et al., 2022) 90 minutes, 4 hours, 24 hours and 3 days after the onset of the stimulation. This approach allowed us to establish that β-catenin repositions to different genomic loci along stimulation time, showing that a definition of Wnt target genes must take into account the time-dimension. Moreover, β-catenin physical targets are largely cell-type specific, as only a subset of them is present across the examined contexts.

A high-resolution single-cell multiomic atlas of the human fetal lung - Organoid

Project description:We obtained human embryonic and fetal lungs from 5-22 pcw for scRNAseq and scATACseq analysis. To focus on epithelial differentiation and region specialization, we deeply sampled 15, 18, 20 and 22 pcw lungs and separated proximal and distal regions while leaving lungs at 5, 6, 9 and 11 pcw intact. These cell samples (except for one at 6pcw) were split and processed for both scRNAseq and scATACseq.

RNA-seq analysis of neonatal mouse cochlear supporting cells [Treated AK]

Project description:This study examined transcripts that are enriched in neonatal mouse cochlear supporting cells at postnatal day 1 and postnatal day 6 after inhibition of the Notch signaling pathway. Cochleas from postnatal day 0 and postnatal day 5 were cultured for 24 hours in the gamma secretase inhibitor DAPT or DMSO as a vehicle control. Supporting cells were purified by FACS sorting for GFP fluorescence from the cochleas of transgenic mice in which a BAC including the LFng locus drives the expression of GFP. Two replicates of GFP+ supporting cells were compared with all other cochlear cell types that were GFP-. We performed this experiment at two different ages, postnatal day 0+24 hours culture and postnatal day 5 + 24 hours culture. (corresponding to P1 and P6). mRNA profiles of P0 and P5 supporting cells (GFP+) and all other cochlear cell types (GFP-) treated with DAPT or DMSO, two replicates each, were generated by deep sequencing using Illumna TruSeq.

RNA-Seq of WT Flp-In T-REx 293, UPF3A knockout and UPF3A overexpression cell lines in part with additional siRNA-mediated control or UPF3B knockdowns

Project description:UPF3A and UPF3B are paralogous genes in human cells that are involved in the nonsense-mediated decay (NMD) pathway. NMD is a cellular quality control mechanism that monitors mRNAs during translation. Aberrant translation due to features such as the presence of a premature stop codon downstream on an exon-exon junction activates NMD and leads to the degradation of the mRNA. To investigate the role of UPF3B and UPF3A in NMD, we have generated UPF3A knockout (KO) human Flp-In T-REx 293 cells using CRISPR-Cas9, as well as FLAG-tagged UPF3A overexpressing cells using the PiggyBac transposon system. We generated RNA-Sequencing data for wildtype, UPF3A KO and UPF3A overexpressing (OE) cells, in part with additional siRNA-mediated knockdown of Luciferase (Luc) as control or UPF3B.
