Notum promotes thermogenesis and protects against diet-induced obesity and insulin resistance in mice

ABSTRACT: Notum is a liver-secreted inhibitor of Wnt signaling pathway, which protected against diet induced obesity and improved glucose homeostasis when overexpressed in the mouse liver. Adeno-associated virus (AAV) vectors were used to overexpress green fluorescent protein (GFP) or Notum in the livers of male C57BL/6J mice maintained on a chow diet. Four weeks after the AAV injection, inguinal white adipose tissue (WAT) of these mice were collected to study Notum’s effect on gene expression. RNA-seq analysis of inguinal WAT collected from these mice revealed a highly significant enrichment of extracellular matrix (ECM) gene set among the down-regulated genes in the AAV-Notum group as compared to the AAV-GFP group. These data suggest that Notum inhibits WAT fibrosis, which may be one of the mechanisms by which Notum improves glucose homeostasis.

Gene expression analysis of HepG2 cells by NOTUM RNAi

Project description:We identified human NOTUM, a new member of beta-catenin target gene. The aim of this analysis is to examine downstream genes of NOTUM. Keywords: Gene expression analysis in response to RNA interference HepG2 cells with RNAi duplexed were used. One control (control-low GC) and 2 RNAi duplexes (NOTUM RNAi#1 and #2) for NOTUM silencing were added to HepG2 cells, and total RNAs were isolated at 72 hours after transfection.

NOTUM-MEDIATED WNT SILENCING DRIVES EXTRAVILLOUS TROPHOBLAST CELL LINEAGE DEVELOPMENT [Notum knockdown]

Project description:WNT activated signal transduction is a conserved regulator of morphogenesis of many organ systems, including the placenta. In human trophoblast stem (TS) cells, activation of canonical WNT signaling is a key to maintenance of the TS cell stem state. NOTUM, a negative regulator of canonical WNT signaling, was prominently expressed in first trimester EVT cells developing in situ and upregulated in EVT cells derived from human TS cells. Furthermore, NOTUM was required for human TS cell differentiation to EVT cells. Canonical WNT signaling is essential for maintaining human trophoblast cell stemness and prevention of human TS cell differentiation. Downregulation of canonical WNT signaling via the actions of NOTUM is required for EVT cell differentiation.

Notum Regulates the Cusp and Root Patterns in Mouse Molar

Project description:Notumis a direct target of Wnt/β-catenin signaling and plays a crucial role as a Wnt inhibitor within a negative feedback loop. In the tooth, Notum is known to be expressed in odontoblasts, and severe dentin defects and irregular tooth roots have been reported in Notum-deficient mice. However, the precise expression pattern of Notum in early tooth development, and the role of Notum in crown and root patterns remain elusive. In the present study, we identified a novel Notum expression in primary enamel knot (EK), secondary EKs, and dental papilla during tooth development. Notum-deficient mice exhibited enlarged secondary EKs, resulting in broader cusp tips, altered cusp patterns, and reduced concavity in crown outline. These alterations in crown outline led to a reduction in cervical tongue length, thereby inducing root fusion in Notum-deficient mice. Overall, these results suggest that the size of secondary EK size, regulated by the Wnt/Notum negative feedback loop, has a significant impact on the patterns of crown and root during tooth morphogenesis.
