Zinc oxide Nanoparticles exposure impairs cranial neural crest development by inducing oxidant stress during chicken embryogenesis

Project description:This manuscript is about our recent work on investigating the effective mechanism of Zinc oxide Nanoparticles on the malformation of craniofacial skeleton. Briefly, we focused on addressing the phenotype of destroyed cranial neural crest cells’ development where the effect of oxidant stress was explored when developing early embryos were exposed to Zinc oxide Nanoparticles during the embryogenesis.

Crest to Trough Cellular Drifting of Green-Synthesized Zinc Oxide and Silver Nanoparticles.

Project description:Green nanotechnology facilitates the blooming of zinc oxide (ZnO) and silver (Ag) nanoparticles (NPs) with distinct flowerlike and spherical morphologies, respectively. The well-characterized NPs with an average size of 35 nm (ZnO) and 25 nm (Ag) were functionalized on the cresty plates for antibacterial inhibition against Staphylococcus aureus and Pseudomonas aeruginosa, with the flowerlike ZnONPs exhibiting 90.9% inhibition and AgNPs exhibiting 100% inhibition. Further, the in vivo underwater troughs for hematological, immunological, and serological analysis in Labeo rohita exhibited 102 > 575 > 104 and 206 > 109 > 81% at concentrations of 1, 2, and 3 mg/L with 4-day and 15-day treatment, respectively, over ZnONPs. However, AgNPs exhibited 257 > 408 > 124 and 86 > 202 > 43% with 4-day and 15-day treatment, respectively, at the same concentrations. The classical ZnNPs and AgNPs exhibited excellent inhibition potential and significant transfiguration of hematological, enzymological, and protein parameters as safe nanomedicine, but ZnONPs were found to be 58, 69, 29 and 34, 51, 70% more active than AgNPs with 4-day and 15-day treatment, respectively. Therefore, the onset of ROX and antioxidant arena favors beneficial cellular drifting of NPs.

ADAM13 knockdown in Xenopus laevis cranial neural crest

Project description:ADAMs are transmembrane metalloproteases that control cell behavior by cleaving both cell adhesion and signaling molecules. The cytoplasmic domain of ADAMs can regulate the proteolytic activity by controlling the subcellular localization and/or the activation of the protease domain. Here we show that the cytoplasmic domain of ADAM13 is cleaved and translocates into the nucleus. Preventing this translocation renders the protein incapable of promoting cranial neural crest (CNC) cell migration in vivo, without affecting its proteolytic activity. In addition, the cytoplasmic domain of ADAM13 regulates the expression of multiple genes in the CNC. This study shows that the cytoplasmic domain of ADAM metalloproteases can perform essential functions in the nucleus of cells and may contribute substantially to the overall function of the protein. Total RNA from cranial neural crest explants dissected from Xenopus laevis embryos at stage 15 to 17. Embryos were injected with either control morpholino (CMO), morpholino to ADAM13 (MO13) or MO13 and a fusion between GFP- and the cytoplasmic domain of ADAM13 (GFP-C13). Triplicate microarray correspond to independent experiments labeled DA4, DA5 and DA2. For each sample 1 is CMO, sample 2 is MO13 and sample 3 is MO13+C13. Embryos were injected with 10 ng of morpholino and 0.5 ng of GFP-C13 mRNA. Supplementary files: [1] matrix2_sig-genes.txt CNC array: Genes significantly affected by the loss of ADAM13 p<0.01. Normalized probe set generated by GC-RMA. [2] matrix3_sig-genes.txt CNC array: Genes significantly affected by the loss of ADAM13 and the addition of GFP-C13 p<0.01.

Post-transcriptional regulation in cranial neural crest cells expands developmental potential [I]

Project description:Developmental potential is progressively restricted after germ layer specification during gastrulation. However, cranial neural crest cells challenge this paradigm, as they develop from anterior ectoderm yet give rise to both mesodermal derivatives of the craniofacial skeleton and ectodermal derivatives of the peripheral nervous system. How cranial neural crest cells differentiate into multiple lineages is poorly understood. Here, we demonstrate that cranial neural crest cells possess a transient state of increased chromatin accessibility; and that the earliest premigratory neural crest are biased towards either a neuronal or ectomesenchymal fate, with each lineage expressing distinct factors from the pluripotent state. We profile the spatiotemporal emergence of each neural crest population and demonstrate that the ectomesenchymal lineage forms prior to the neuronal progenitors. Expression of the pluripotency microRNA family miR-302 is maintained in cranial neural crest cells and genetic deletion leads to precocious specification of the ectomesenchymal lineage. We find that miR-302 directly targets Sox9 to slow the timing of ectomesenchyme induction and regulates multiple genes involved in chromatin condensation to maintain accessibility for neuronal differentiation. Loss of mir-302 results in reduced chromatin accessibility in the neuronal progenitor lineage of neural crest and a reduction in peripheral neuron differentiation. Our findings reveal a post-transcriptional mechanism governed by miRNAs from pluripotency as an important mechanism to expand developmental potential of cranial neural crest.

Single-cell profiling of cranial neural crest diversification across a vertebrate lifetime

Project description:The cranial neural crest (CNC) is a vertebrate-specific population that generates a huge diversity of derivatives, including the bulk of the connective and skeletal tissues of the head. How neural crest cells generate the appropriate cell types for distinct head regions over time remains unresolved. Here we profile RNA expression (scRNAseq) and chromatin accessibility (snATACseq) of the zebrafish cranial neural crest lineage at single-cell resolution from embryos to adults.

Human ESC differentiation into cranial neural crest cells in the presence of PhenDC3

Project description:Human ESC differentiation into cranial neural crest cells in the presence of PhenDC4. Human embryonic stem cells (hESC) were differentiated into cranial neural crest cells in presence of the G-quadruplex stabilising ligand PhenDC3 or DMSO control. The case when no PhenDC3 or DMSO have been included in the differentiation protocol represent an additional control experiment.
