Introduction

Component of the multi-pass translocon (MPT) complex that mediates insertion of multi-pass membrane proteins into the lipid bilayer of membranes (PubMed:32820719, PubMed:36261522). The MPT complex takes over after the SEC61 complex: following membrane insertion of the first few transmembrane segments of proteins by the SEC61 complex, the MPT complex occludes the lateral gate of the SEC61 complex to promote insertion of subsequent transmembrane regions (PubMed:36261522).

AbstractAmyotrophic lateral sclerosis (ALS) is a severe motor neuron disease with uncertain genetic predisposition in most sporadic cases. The spatial architecture of cell types and gene expression are the basis of cell–cell interactions, biological function and disease pathology, but are not well investigated in the human motor cortex, a key ALS-relevant brain region. Recent studies indicated single nucleus transcriptomic features of motor neuron vulnerability in ALS motor cortex. However, the brain regional vulnerability of ALS-associated genes and the genetic link between region-specific genes and ALS risk remain largely unclear.Here, we developed an entropy-weighted differential gene expression matrix-based tool (SpatialE) to identify the spatial enrichment of gene sets in spatial transcriptomics. We benchmarked SpatialE against another enrichment tool (multimodal intersection analysis) using spatial transcriptomics data from both human and mouse brain tissues. To investigate regional vulnerability, we analysed three human motor cortex and two dorsolateral prefrontal cortex tissues for spatial enrichment of ALS-associated genes. We also used Cell2location to estimate the abundance of cell types in ALS-related cortex layers. To dissect the link of regionally expressed genes and ALS risk, we performed burden analyses of rare loss-of-function variants detected by whole-genome sequencing in ALS patients and controls, then analysed differential gene expression in the TargetALS RNA-sequencing dataset.SpatialE showed more accurate and specific spatial enrichment of regional cell type markers than multimodal intersection analysis in both mouse brain and human dorsolateral prefrontal cortex. Spatial transcriptomic analyses of human motor cortex showed heterogeneous cell types and spatial gene expression profiles. We found that 260 manually curated ALS-associated genes are significantly enriched in layer 5 of the motor cortex, with abundant expression of upper motor neurons and layer 5 excitatory neurons. Burden analyses of rare loss-of-function variants in Layer 5-associated genes nominated NOMO1 as a novel ALS-associated gene in a combined sample set of 6814 ALS patients and 3324 controls (P = 0.029). Gene expression analyses in CNS tissues revealed downregulation of NOMO1 in ALS, which is consistent with a loss-of-function disease mechanism. In conclusion, our integrated spatial transcriptomics and genomic analyses identified regional brain vulnerability in ALS and the association of a layer 5 gene (NOMO1) with ALS risk.

Biological Role of Nodal Modulator: A Comprehensive Review of the Last Two Decades

Review

Author: Sun, Yuhui ; Qian, Xin ; Li, Tao

Nodal modulator (NOMO) is a type I transmembrane protein that is conserved in various human tissues. Humans have three highly similar NOMO proteins, namely NOMO1, NOMO2, and NOMO3. These three proteins are closely related and may have similar functions. NOMO has been identified as a part of a protein complex that mediates a wide range of biological processes such as tumor formation, bone and cartilage formation, embryo formation, facial asymmetry, and development of congenital heart disease. To date, a few studies have focused on the role of NOMO; however, the mechanism underlying its effects remains unknown. To improve our understanding regarding NOMO, we reviewed the role of NOMO in different diseases and investigated the mechanism underlying its effects.

PURPOSEMicroRNA (miRNA) is known to be involved in the pathological process of congenital heart disease (CHD), and nodal modulator1 (NOMO1) is a critical determinant of heart formation. The present study aims to discover the effect of miR-33a-5p and NOMO1 on CHD.METHODSQuantitative real-time polymerase chain reaction (qRT-PCR) was used to detect expressions of miR-33a-5p mimic or inhibitor and overexpressed NOMO1 plasmid orNOMO1 knockdown. Human cardiomyocyte progenitor cells (hCMPCs) proliferation was measured by cell counting kit-8 (CCK-8) at 24, 48 and 72 h. Flow cytometry was applied to investigate hCMPCs cell cycle progression and apoptosis. Expressions of cell apoptotic proteins Bax, Cleaved(C) caspase-3 and Bcl-2, and expressions of cardiomyocyte differentiation markers GATA4, troponin T (cTnT) and myocyte enhancer factor2C (MEF2C) in hCMPCs were identified by qRT-PCR and western blot. Target genes and potential binding sites of NOMO1 and miR-33a-5p were predicted with Targetscan 7.2, and was confirmed through dual-luciferase reporter assay.RESULTSUp-regulation of miR-33a-5p inhibited hCMPCs proliferation, cell cycle G0/S transition but promoted hCMPCs apoptosis, which was partially mitigated by overexpressed NOMO1. NOMO1 was the target gene of miR-33a-5p. Expressions of Bax and C caspase-3 were enhanced but expressions of Bcl-2, GATA4, cTnT and MEF2C were reduced by up-regulation of miR-33a-5p, which was partially mitigated by overexpressed NOMO1.CONCLUSIONUp-regulation of miR-33a-5p inhibited hCMPCs proliferation, cell cycle G0/S transition and differentiation into cardiomyocytes but promoted apoptosis via targeting NOMO1.
