Project description:The NOTCH signaling pathway plays an important role in regulating various biological processes, including cell proliferation, lineage specification and apoptosis. Multiple components of the NOTCH pathway have been identified in mammalian preimplantation embryos. However, the precise role of NOTCH pathway in early embryonic development is poorly understood, especially in domestic animals. Here, we show that key transcripts of the NOTCH pathway exhibit a dynamic pattern throughout early embryonic development with an abundant level before embryonic genome activation in cattle. We also confirmed the presence of active NOTCH1 and RBPJ. By using pharmacological and RNAi tools, we demonstrated that the NOTCH pathway is required for the proper development of bovine early embryos. This functional consequence could be partly attributed to the major transcriptional mediator-RBPJ, whose deficiency also compromised the embryo quality. Indeed, we observed a significant increase of histone H3 serine 10 phosphorylation (pH3S10, a mitosis marker) positive blastomeres in not only NOTCH1 depleted embryos but RBPJ depleted ones. Importantly, RNA-seq analysis revealed that either NOTCH1 or RBPJ depletion triggers a reduction in H1FOO that encodes the oocyte-specific linker histone H1 variant. Interestingly, depleting H1FOO also results in detrimental effects on the developmental competence of early embryos, similar with NOTCH1 inhibition. Overall, our results reveal a crucial role for NOTCH pathway in regulating bovine preimplantation development, likely by controlling cell proliferation and maintaining H1FOO expression.

Project description:This randomized phase I/II clinical trial is studying the side effects and best dose of gamma-secretase/notch signalling pathway inhibitor RO4929097 when given together with vismodegib and to see how well they work in treating patients with advanced or metastatic sarcoma. Vismodegib may slow the growth of tumor cells. Gamma-secretase/notch signalling pathway inhibitor RO4929097 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving vismodegib together with gamma-secretase/notch signalling pathway inhibitor RO4929097 may be an effective treatment for sarcoma.

Project description:Cell signaling pathways play key roles to coordinate cellular events in development. Notch signaling pathway is highly conserved across all multicellular animals and is known to co- ordinate a multitude of diverse cellular events, including proliferation, differentiation, fate specification, and cell death. Specific functions of the pathway are however highly context- dependent and are not well characterized in post-traumatic regeneration. Here, we use a small-molecule inhibitor of the pathway (DAPT) to demonstrate that Notch signaling is required for proper arm regeneration in the brittle star Ophioderma brevispina, a highly re- generative member of the phylum Echinodermata. We also employ a transcriptome-wide gene expression analysis (RNA-seq) to characterize the downstream genes controlled by the Notch pathway in the brittle star regeneration.

Project description:The Notch signaling pathway functions in a number of processes during embryologic development, especially the maintenance or aquisition of cell fate. We purturb the Notch signalling pathway in embryonic Xenopus laevis in order to 1) better characterize the downstream targets of Notch signalling, and 2) determine the extent to which early embryos can recover from transient purturbations to critical signalling pathways, if at all. Xenopus laevis embryos were unilaterally injected at the two cell stage with either GFP, GFP and ICD (Notch intracellular domain, an up-regulator of the Notch pathway), or GFP and DBM (domain-binding mutant, a downregulator of the Notch pathway). At stages 18, 28, and 38, for each injection, pooled total RNA from 10 embryos was extracted. Extraction was performed for three biological replicates for each time/injection condition. cDNA from total RNA was hybridized on Affymetrix Xenopus laevis Genome 2.0 arrays.

Project description:Current understandings of the initiation of the trophectoderm (TE) program in mammalian embryonic development lacks evidence of how TE-associated factors such as CDX2 and GATA3 participate in bovine lineage specification. In this study, we describe the effects of TE-associated factors on lineage specification marker genes such as SOX2, OCT4, NANOG, GATA6 and SOX17, assisted by a cytosine base editor system. Interestingly, GATA3 downregulates the NANOG expression in bovine blastocysts. Further analysis of the blastocyst mosaic shows that GATA3 is required for NANOG in TE cells of bovine blastocysts. It is worthy to notice that, unlike mouse embryos where GATA3 and CDX2 did not reciprocally affect each other in bovine embryos.

Project description:We have manipulated the NOTCH signaling pathway in mouse embryonic endocardial cells by the co-culture with OP9 stromal cells expressing Jag1 and Dll4, the culture over recombinant JAG1 and DLL4, and the use of the γ-secretase inhibitor RO4929097. We have performed RNA-seq and ATAC-seq to define the transcriptional profile and the chromatin accessibility landscape specific for each condition.

Project description:The Notch signaling pathway controls cell fates through interactions between neighboring cells by positively or negatively affecting, in a context-dependent manner, processes of proliferation, differentiation, and apoptosis1. It has been implicated in human cancer both as an oncogene and a tumor suppressor2. Here we report, for the first time, novel inactivating mutations in the Notch pathway components in over forty percent of the human bladder cancers examined. Bladder cancer is the fourth most commonly diagnosed malignancy in the US male population3. Thus far, driver mutations in the FGFR3 and less commonly RAS proteins have been identified4,5. We show that Notch activation in bladder cancer cells suppresses proliferation both in vitro and in vivo by directly upregulating dual specificity phosphatases (DUSPs), thus reducing ERK1/2 phosphorylation. In mouse models, genetic inactivation of Notch signaling leads to ERK1/2 phosphorylation resulting in tumorigenesis in the urinary tract. In recent years, the tumor suppressor role of Notch has been recognized by loss-of-function mutations identified in myeloid cancers6 as well as squamous cell carcinomas of the skin, lung7, and the head and neck8,9. Of the 4 Notch receptors (N1-4), only N1 and 2 have been implicated in human cancer. two biological replicates from normal and tumor urothelial tissue were hybridized on Affymetrix mm 430 2.0 chips
