Abstract:
Background:Systemic and periarticular bone loss in rheumatoid arthritis (RA) is mediated by osteoclasts, multinucleated cells originating from the myeloid lineage. Recently, Notch signaling pathway has emerged as a potential regulator of osteoclast progenitor (OCP) differentiation and activation.Objectives:The exact role of Notch signaling in the context of arthritis is still unknown; however, its inhibition has beneficial effects in animal arthritis models. We aimed to determine the expression of Notch receptors and ligands on specific OCP subpopulations and define changes that occur in murin

Abstract:
Signaling through Notch receptors has been implicated in the control of cellular differentiation in animals ranging from nematodes to humans. Starting from a human expressed sequence tag-containing sequence resembling that of Serrate, the gene for a ligand of Drosophila melanogaster Notch, we assembled a full-length cDNA, now called human Jagged2, from overlapping cDNA clones. The full-length cDNA encodes a polypeptide having extensive sequence homology to Serrate (40.6% identity and 58.7% similarity) and even greater homology to several putative mammalian Notch ligands that have subsequently

Abstract:
Abstract Microenvironment in the stem cell niche plays an important role to regulate self-renewal and differentiation of hematopoietic stem cells (HSCs). We previously showed opposing effects of b-catenin activation on HSC depending on target of activation in the bone marrow microenvironment. To further analyze the microenvironmental regulation of HSC by Wnt/b-catenin signal, we examined b-catenin activation mode in the trabecular bone marrows. In-situ immunohistochemistry of bone marrows revealed a compartmentalized enrichment of b-catenin in the spindle shaped, CD45(−) endosteal stroma of bo

Abstract:
Abstract The Notch developmental pathway regulates cell fate in tumor angiogenesis and influences immune cell phenotypes in the tumor microenvironment (TME). While Notch receptors Notch1-3 have been extensively studied, the role of Notch4 in the tumor microenvironment is poorly understood. Previous efforts to target Notch signaling and tumor angiogenesis have been limited by broad expression of Notch receptors and their cognate ligands, leading to significant gastrointestinal toxicity. However, Notch4 is thought to be expressed primarily in the endothelium, making it a highly specific and, the

Abstract:
Abstract Background: The NOTCH signaling pathway is a highly conserved signaling system regulated by close-range cell-to-cell interactions. The interaction between NOTCH receptors (NOTCH1-4) and "classical" ligands, or the activation of other non-classical pathways, is associated with the occurrence and progression of various tumors. Although some studies have confirmed a correlation between the efficacy of immunotherapy and NOTCH gene mutations, no definitive conclusion has been reached in colorectal cancer. Exploring the tumor immune microenvironment may help us find better answers. Methods:

Introduction: Early T-cell precursor acute lymphoblastic leukemia (ETP T-ALL) is a distinct subtype of T-ALL characterized by higher rates of relapse and induction failure. Large-scale genetic sequencing studies have identified frequently mutated oncogenes and gene fusions in ETP T-ALL, while bulk transcriptome analyses have revealed expression features resembling myeloid precursors and myeloid malignancies. However, the contributions of intra-tumoral functional heterogeneity and microenvironment to tumor biology and treatment failure remain unknown. Methods: We performed full-length single-ce

Methods: We assessed using immunohistochemistry (IHC) and quantitative real-time PCR (qPCR) with SYBR Green the profile of predictive markers involved in the cascade of events leading to the formation and progression: invasiveness, angiogenesis and antiapoptotic mechanisms. 80 RCC tissues were detected by IHC.

Abstract:
Introduction The development and maturation of B cells is highly dependent on signals provided by the microenvironment of the lymphatic organs. As B cells move from one developmental stage and niche to the next, the integrin family of adhesion molecules provides important cues for their correct positioning and retention. The integrin adaptor protein Kindlin-3 (encoded by the Fermt3 gene) regulates integrin activity and function in a wide range of hematopoietic cell types. In this study, we aimed to define its precise role in the development and function of the different murine B cell subsets.

Background: Notch receptors are critical determinants of cell fate in a variety of organisms. Notch signaling is involved in the chondrogenic specification of neural crest cells. Aberrant Notch activity has been implicated in numerous human diseases including cancers; however its role in chondrogenic tumors has not been clarified.

Abstract:
Background: Squamous odontogenic tumor (SOT) is a rare benign odontogenic epithelial neoplasm. A slow-growing painless expansive swelling is the common presenting symptom. Histopathologically, SOT can be easily misdiagnosed as an acanthomatous ameloblastoma. Although Notch receptors and ligands have been shown to play a role in cell fate decisions in ameloblastomas, the role of these cell signaling molecules in SOT is unknown.
