INTRODUCTION: We investigated associations of obesity with the expression of Alzheimer's disease (AD)-related genes in a large community-based cohort. METHODS: The sample consisted of 5619 participants from the Framingham Heart Study. Obesity metrics included body mass index (BMI) and waist-to-hip ratio (WHR). Gene expression was measured for a set of 74 AD-related genes, derived by integrating genome-wide association study results with functional genomics data...

Recent demographic studies predict there will be a considerable increase in the number of elderly people within the next few decades. Aging has been recognized as one of the main risk factors for the world's most prevalent diseases such as neurodegenerative disorders, cancer, cardiovascular disease, and metabolic diseases. During the process of aging, a gradual loss of tissue volume and organ function is observed, which is partially caused by replicative senescence. The capacity of cellular proliferation and replicative senescence is tightly regulated by their telomere length...

Primary cilia are organelles consisting of axonemal microtubules and plasma membranes, and they protrude from the cell surface to the extracellular region and function in signal sensing and transduction. The integrity of cilia, including the length and structure, is associated with signaling functions; however, factors involved in regulating the integrity of cilia have not been fully elucidated. Here, we showed that the Rab GTPase-binding protein EHBP1L1 and its newly identified interactors CD2AP and CIN85, known as adaptor proteins of actin regulators, are involved in ciliary length control...

Minimal change disease (MCD) is the common type of nephrotic syndrome in children. There is an urgent need to explore new treatment methods as current treatments have many drawbacks and cause significant side effects. Our group found that Angiopoietin-like protein 3 (Angptl3) is closely related to renal disease and Angptl3 knockout significantly alleviated proteinuria in mice with adriamycin nephropathy (AN), however, some proteinuria was still present. Minnelide is a water-soluble prodrug of triptolide which has been used for the treatment of glomerular diseases...

While genome wide association studies (GWASs) of Alzheimer's Disease (AD) in European (EUR) ancestry cohorts have identified approximately 83 potentially independent AD risk loci, progress in non-European populations has lagged. In this study, data from the Million Veteran Program (MVP), a biobank which includes genetic data from more than 650,000 US Veteran participants, was used to examine dementia genetics in an African descent (AFR) cohort. A GWAS of Alzheimer's disease and related dementias (ADRD), an expanded AD phenotype including dementias such as vascular and non-specific dementia that included 4012 cases and 18,435 controls age 60+ in AFR MVP participants was performed...

ETHNOPHARMACOLOGICAL RELEVANCE: The incidence of membranous nephropathy (MN) continues to rise globally. Shenqi granule (SQ), composed of thirteen Chinese medicinal herbs, has clinical efficacy in the treatment of MN and has been used in China for decades. However, the mechanism behind this effect remains unclear. AIM OF THE STUDY: In this study, we documented the effects of SQ on cultured mouse podocytes (MPC5) cytoskeletal proteins (CD2AP, α-actinin4) and autophagic activity, and identified the mechanism underlying the ameliorating effects of SQ on MN...

Recurrent miscarriage (RM) is a chronic, heterogeneous autoimmune disease that has serious social and personal consequences. No valid and reliable diagnostic markers or therapeutic targets for RM have been identified. Macrophages impact the innate immune system and can be used as diagnostic and prognostic markers for many diseases. We first collected 16 decidua and villi tissue samples from 5 normal patients and 3 RM patients for single-cell RNA sequencing data analysis and identified 1293 macrophage marker genes...

Pathogenic bacteria possess a great potential of causing infectious diseases and represent a serious threat for human and animal health. Understanding the molecular basis of infection development can provide new valuable strategies for disease prevention and better control. In host-pathogen interactions, actin-cytoskeletal dynamics plays a crucial role for successful adherence, invasion and intracellular motility of many intruding microbial pathogens. Cortactin, a major cellular factor that promotes actin polymerization and other functions, appears as a central regulator of host-pathogen interactions and different human diseases including cancer development...

Mastitis is characterized by inflammatory damage to mammary gland tissue, which could decline milk production and quality and significantly affect the economic benefits of ranching. MicroRNAs (miRNAs), such as miR-199a-3p, are novel therapeutic targets in inflammation, and their regulation is an effective strategy for inflammation control. Despite its importance in humans and animals, the molecular mechanism of bovine miR-199a-3p (bta-miR-199a-3p) in dairy cow mastitis and bovine mammary epithelial cell (bMEC) inflammation is unclear...

Background: Since 2011, three large-scale genome-wide association studies (GWAS) have confirmed that the CD2AP rs9349407 polymorphism is significantly connected with Alzheimer's disease (AD) in individuals of European descent. Subsequently, this association has been replicated in European populations, but is unclear whether it can be replicated in Chinese. Recently, the correlation between rs9349407 and AD in the Chinese population has become a research hotspot. Objective: To explore the association between rs9349407 polymorphism and AD in the Chinese population...

OBJECTIVE: We wanted to explore how angiopoietin-like 3 (ANGPTL3) impact hyperlipidemia-induced renal injury. METHODS: ANGPTL3 knockout mice and wild-type C57 mice were set up in four groups (N = 5) depending on a normal or 60% high-fat diet: wild-type with normal diet (WT), angptl3-/- with normal diet (KO), wild-type + high-fat diet (WT + HF) and angptl3-/- + high-fat diet (KO + HF). The detection time points were the 9th, 13th, 17th and 21st weeks after modeling...

There is a paucity of data identifying genetic mutations that account for the high rate of steroid-resistant nephrotic syndrome (SRNS) in a South African paediatric population. The aim was to identify causal mutations in genes implicated in SRNS within a South African paediatric population. We enrolled 118 children with primary nephrotic syndrome (NS), 70 SRNS and 48 steroid-sensitive NS. All children with SRNS underwent kidney biopsy. We first genotyped the NPHS2 gene for the p.V260E variant in all NS cases (n = 118) and controls (n = 219)...

Genome-wide association studies (GWAS) have identified common single nucleotide polymorphisms (SNPs) that increase late-onset Alzheimer's disease (LOAD) risk. To identify additional LOAD-associated variants and provide insight into underlying disease biology, we performed a phenome-wide association study on 23 known LOAD-associated SNPs and 4:1 matched control SNPs using UK Biobank data. LOAD-associated SNPs were significantly enriched for associations with 8/778 queried traits, including 3 platelet traits...

Establishment of apicobasal polarity and the organization of the cytoskeleton must operate coordinately to ensure proper epithelial cell shape and function. However, the precise molecular mechanisms by which polarity complexes directly instruct the cytoskeletal machinery to determine cell shape are poorly understood. Here, we define a mechanism by which the PAR polarity complex (PAR3-PAR6-aPKC) at apical cell junctions leads to efficient assembly of the apical actomyosin network to maintain epithelial cell morphology...

Genome-wide association studies (GWAS) have been highly informative in discovering disease-associated loci but are not designed to capture all structural variations in the human genome. Using long-read sequencing data, we discovered widespread structural variation within SINE-VNTR- Alu (SVA) elements, a class of great ape-specific transposable elements with gene-regulatory roles, which represents a major source of structural variability in the human population. We highlight the presence of structurally variable SVAs (SV-SVAs) in neurological disease-associated loci, and we further associate SV-SVAs to disease-associated SNPs and differential gene expression using luciferase assays and expression quantitative trait loci data...

BACKGROUND: CD2-Associated protein (CD2AP) is associated with increased risk of late-onset Alzheimer's disease. We have previously shown that loss of CD2AP's Drosophila homolog, cindr, exacerbates Tau toxicity and impairs synaptic maturation and function at the neuromuscular junction. However, little is understood about CD2AP at the central mammalian synapse. The present study demonstrates conservation of CD2AP function at the pre-synapse from fly to mouse, as well as characterizes CD2AP's role in maintaining post-synaptic structure and function...

BACKGROUND: In late-onset Alzheimer's disease (LOAD), the causal mechanisms of synaptic dysfunction underlying memory deficits that lead to dementia remain unclear. Genetic studies of LOAD patients identified gene variants associated with AD. Now it is necessary to translate the genotype into the mechanism of synaptic dysfunction. Here we investigated the impact of the putative LOAD risk factor CD2AP loss of function. We hypothesized that CD2AP might regulate spinal actin since CD2AP is a regulator of actin dynamics in non-neuronal cells, and the actin cytoskeleton dynamics is essential for spine plasticity...

Acute kidney injury (AKI) caused by sepsis has a high incidence and poor prognosis. Thus, novel strategies that minimize AKI are urgently needed. In our previous research, we found that angiopoietin-like protein 3 (Angptl3) knockout exerts protective effects on kidney injury in adriamycin nephropathy. However, the role of Angptl3 in the pathogenesis of AKI is largely unclear. This study aimed to explore the renal protective effects and molecular mechanisms of Angptl3 knockout in lipopolysaccharide (LPS)-induced AKI in mice...

INTRODUCTION: Rs9296559 within CD2-associated protein (CD2AP) has been identified as a susceptibility locus for Alzheimer's disease (AD). Recent studies indicated that CD2AP functioned as a regulator of endocytic trafficking to modulate the β-amyloid (Aβ) generation in neurons. Moreover, knockdown of cindr, the Drosophila ortholog of CD2AP, enhanced tau-induced neurodegeneration, implying CD2AP also participated in tau pathology. However, the role of rs9296559 in regulating Aβ and tau metabolism in AD was still unclear...

A growing list of Alzheimer's disease (AD) genetic risk factors is being identified, but the contribution of each variant to disease mechanism remains largely unknown. We have previously shown that elevated levels of reactive oxygen species (ROS) induces lipid synthesis in neurons leading to the sequestration of peroxidated lipids in glial lipid droplets (LD), delaying neurotoxicity. This neuron-to-glia lipid transport is APOD/E-dependent. To identify proteins that modulate these neuroprotective effects, we tested the role of AD risk genes in ROS-induced LD formation and demonstrate that several genes impact neuroprotective LD formation, including homologs of human ABCA1 , ABCA7 , VLDLR , VPS26 , VPS35 , AP2A , PICALM , and CD2AP Our data also show that ROS enhances Aβ42 phenotypes in flies and mice...
