Reovirus infection is regulated by NPC1 and endosomal cholesterol homeostasis.

PLoS Pathogens, 2022
Cholesterol homeostasis is required for the replication of many viruses, including Ebola virus, hepatitis C virus, and human immunodeficiency virus-1. Niemann-Pick C1 (NPC1) is an endosomal-lysosomal membrane protein involved in cholesterol trafficking ...

A multiplex interactome of Ebola virus proteins reveals TM9SF2 as a cell‐surface attachment factor that promotes viral entry

iMetaOmics, Volume 3, Issue 3, September 2026.
This study generates a comprehensive Ebola virus (EBOV)‐human protein–protein interactome, comprising 1728 core high‐confidence interactions. Further interactome analysis revealed the potential association of EBOV glycoprotein (GP) with the host factor TM9SF2. Subsequent mechanistic investigations confirmed that TM9SF2 functions as an attachment factor

The Niemann–Pick C1 Protein of Patients with Hepatocellular Carcinoma Is Associated with Survival Time in Males and Tumor Size in Females

Biomedicines
Background/Objectives: The Niemann–Pick C1 (NPC1) protein regulates cellular cholesterol homeostasis, which is disrupted in hepatocellular carcinoma (HCC). Sex differences in cholesterol metabolism may also be related to NPC1 expression in HCC.

Pneumococcal Immunization Reduces Neurological and Hepatic Symptoms in a Mouse Model for Niemann-Pick Type C1 Disease

Frontiers in Immunology, 2019
Niemann-Pick type C1 (NPC1) disease is caused by a deleterious mutation in the Npc1 gene, causing lysosomal accumulation of unesterified cholesterol and sphingolipids.

Lysosomal Dysfunction Is Associated With Intervertebral Disc Degeneration: Multiomics and Machine Learning Identify Molecular Subtypes and Hub Genes

The Journal of Gene Medicine, Volume 28, Issue 9, September 2026.
Intervertebral disc degeneration (IVDD) is linked to lysosomal dysfunction, impaired autophagic degradation, and cellular senescence. Integrating bulk and single‐cell transcriptomics with machine learning, this study identified two lysosome‐related molecular subtypes and four hub genes: HYAL1, MMD, PLD3, and ANK3.

Reduced VLDL clearance in Apoe−/−Npc1−/− mice is associated with increased Pcsk9 and Idol expression and decreased hepatic LDL-receptor levels

Journal of Lipid Research, 2010
Niemann-Pick type C1 (NPC1) promotes the transport of LDL receptor (LDL-R)-derived cholesterol from late endosomes/lysosomes to other cellular compartments.

An Optimized Diagnostic Approach for Adults With Suspected Inherited Metabolic Disorders

Journal of Inherited Metabolic Disease, Volume 49, Issue 5, September 2026.
A multidisciplinary strategy that integrates deep phenotyping with expert genetic interpretation substantially increases the likelihood of reaching a diagnosis in adults suspected of having an IMD. ABSTRACT Inherited metabolic disorders (IMDs) arise from defects in metabolic pathways essential for normal biochemical function.

A comprehensive analysis identifies and validates NPC1 as a potential biomarker for prognosis in HCC

Frontiers in Genetics
Niemann-Pick type C1 protein (NPC1), a key regulator of intracellular cholesterol transport and a transmembrane protein, has been implicated in carcinogenesis, particularly in hepatocellular carcinoma (HCC).

Metabolism in Tumor: Mechanisms and Therapeutic Perspectives

MedComm, Volume 7, Issue 9, September 2026.
Tumor metabolic reprogramming converges on three hubs—the SREBP1/2–FASN–SCD1 lipogenic axis, the HIF‐1α–GLUT1–LDHA glycolytic axis, and the LDLR–SCARB1–LXR cholesterol system—which integrate transcriptional, epigenetic (histone lactylation, m6A), and microenvironmental inputs to generate metabolic plasticity, immune evasion, and therapy resistance ...

Single‐Nucleus Multiomic Analysis Reveals Immune–Metabolic Reprogramming Consistent With Maladaptive Trained Immunity in HIV‐Associated Neurocognitive Disorders

Glia, Volume 74, Issue 8, August 2026.
Single‐nucleus multiomic profiling of postmortem brain reveals coordinated immune, metabolic, and epigenomic reprogramming in glia of people with HIV consistent with maladaptive trained immunity sustaining neuroinflammation in HAND. ABSTRACT HIV‐associated neurocognitive disorders (HAND) remain prevalent in people with HIV (PWH) despite effective ...
