Ketogenic diet (KD) is used for the treatment of drug-resistant childhood epilepsy and has been proposed to improve outcomes in neurodegenerative diseases. However, the mechanisms by which KD alters brain circuitry remain unclear. Here, we investigated the impact of KD on hippocampal function through integrative analysis of gene expression and neurotransmission. We found that KD induces extensive transcriptional reprogramming, including altered expression of numerous synaptic genes. Proteomic and genomic profiling revealed significant changes in histone modifications, particularly at promoters of KD-regulated genes. Electrophysiological recordings showed that KD reduces excitatory synaptic gain and short-term plasticity at CA3-CA1 synapses, dampening the summation …

Estimating The Baseline Age When Longitudinal Changes In Biomarkers Accelerate: Application To An Imaging Study Of Preclinical Alzheimer Disease, Chengjie Xiong, Folasade Agboola, Jingqin Luo

2020-Current year OA Pubs

BACKGROUND: Biomarkers are routinely measured from human biospecimens and imaging scans in Alzheimer disease (AD) research. Age is a well-known risk factor for AD. Detecting the baseline age at which the longitudinal change in biomarkers starts to accelerate is important to design preventive interventions. METHODS: We analyzed longitudinal biomarker data by a random intercept and random slope model where the slope (longitudinal rate of change) was modeled as a piecewise linear and continuous function of baseline age. We proposed to estimate the baseline age at the intersection of the two linear functions by multiple methods: maximum (profile) likelihood, minimum squared …

The benefit of rituximab maintenance after first-line (1L) bendamustine-rituximab (BR) in patients with mantle cell lymphoma (MCL) remains uncertain, with inconsistent results from the phase 2 MAINTAIN trial and several retrospective studies. We conducted a large retrospective study at 27 US and Canadian academic centers to examine the benefit of rituximab maintenance after BR. A total of 911 patients received 1L BR between 2010 and 2020, and 703 had an objective response and no evidence of disease progression at the 3-month post-BR landmark. Among those, 394 (56%) received rituximab maintenance and 309 (44%) did not, with largely similar baseline patient …

BACKGROUND: Gardnerella is a bacterial genera commonly present in the female urogenital tract, especially in bacterial vaginosis. Gardnerella are frequently detected in urine collected directly from the bladder and have been implicated in urinary incontinence and recurrent urinary tract infections. Understanding the contribution of Gardnerella to pathogenesis is complicated by its genetic heterogeneity and a shortage of data from in vivo models. One clinical isolate of Gardnerella triggered urothelial exfoliation and promoted urinary tract infection by uropathogenic E. coli in a mouse model. This study was designed to compare diverse Gardnerella strains in vivo to identify genomic variation associated with …

Genetic Modifiers Of Apoe-Ε4-Associated Cognitive Decline, Alex G Contreras, Carlos Cruchaga, Et Al.

2020-Current year OA Pubs

The APOE-ε4 allele is the strongest genetic risk factor for late-onset Alzheimer's disease. However, APOE-ε4 is not deterministic, highlighting the need to identify additional genetic and environmental factors. APOE-ε4 has been linked to accelerated cognitive decline, so we sought to investigate genetic factors that modify APOE-ε4-associated cognitive decline. We conduct cross-ancestry APOE-ε4-stratified and interaction GWAS using harmonized cognitive data from 32,778 participants, including 29,354 non-Hispanic White and 3,424 non-Hispanic Black individuals. Our primary outcome is late-life cognition, measured using harmonized composite scores for memory, executive function, and language, modeled as continuous traits reflecting both normative cognitive aging and disease-related decline. …

Cell-Cell Communication As Underlying Principle Governing Color Pattern Formation In Teleost Fishes, Marleen Klann, Lila Solnica-Krezel, Et Al.

2020-Current year OA Pubs

The diverse pigmentation patterns of animals are crucial for predation avoidance and behavioral display. This diversity arises from interactions among distinct pigment cell types, yet mechanisms generating pattern variation across teleost fishes remain incompletely understood. In zebrafish, Turing models have been proposed to explain stripe patterns, but it is unclear if they apply to other fishes. Here, we investigate the Snowflake mutant of the anemonefish Amphiprion ocellaris, which displays enlarged white bars with irregular boundaries. Using genome-wide association mapping and targeted sequencing, we identify a missense mutation (E42K) in gja5b, encoding the gap junction protein Connexin 41.8. CRISPR/Cas9-mediated genome editing …

UNLABELLED: Obesity is a complex disease driven by multiple factors, and a deeper understanding of its underlying mechanisms could enable the development of novel treatments. Based on our previous experimental studies, we have proposed a homeostatic mechanism regulating adiposity involving mechano-sensing of body weight by osteoblast-lineage cells in the lower extremities. However, the molecular mechanism underlying this proposed weight-sensing pathway remains to be elucidated. Recent studies have demonstrated that Piezo1-mediated mechano-sensing in osteoblast-lineage cells, as well as TrkA-dependent signaling, are essential for the normal bone anabolic response to high-intensity mechanical loading. We hypothesized that these pathways within bone may also …

Optimization of prophylactic vaccine regimens to elicit strong, long-lasting immunity is an urgent need highlighted by the COVID-19 pandemic. Stronger vaccine immunogenicity is frequently reported in individuals living in high-income countries compared to individuals living in low- and middle-income countries. While numerous host genetic and immune factors may influence vaccine responses, geographic restrictions to vaccine effectiveness may also be influenced by the intestinal microbiota, which modulates host immune systems. However, the potential role of the gut microbiota on responses to HIV-1 vaccines has not yet been explored. We analyzed the bacteriome by targeted 16S sequencing and the virome by virus-like …

Animals must balance behavioral goals with the energetic costs of movement. How such trade-offs are implemented algorithmically during natural behavior, and how they adapt to changing energetic constraints, remains poorly understood. Here we show that larval zebrafish adjust their motor strategies during prey hunting to minimize energy expenditure. Using high-speed video tracking and 3D computational fluid dynamics simulations, we quantified the energy costs (in Joules) of different movement types across three developmental stages. While the structure of discrete movement types ("bouts") remained stable with age, their selection probabilities changed depending on their energetic cost, such that more expensive bouts were …

2020-Current year OA Pubs

Bacterial dissemination across tissues is a critically important process influencing infection outcomes. Monitoring within-host dissemination is challenging because conventional measures of bulk bacterial burden cannot distinguish between lineages that are shared between tissues and those that replicate locally. This limitation can be overcome using barcoded bacteria, where deep sequencing of the barcode locus and comparisons of barcodes between tissues define which lineages spread within the host. Numerous studies have used barcoded bacteria to generate high-resolution maps of dissemination. However, since multiple cells in the infectious inoculum can contain identical barcodes, inferences about dissemination can be confounded when distinct lineages from …

DNA repair mechanisms are essential for cellular development and function. In post-mitotic neurons, deficiencies in DNA damage response proteins can lead to severe neurodegenerative and neurodevelopmental disorders. One highly conserved factor involved in DNA repair is MutS Homolog 2 (Msh2), which is responsible for correcting base-base mismatches and insertion/deletion loops during cell proliferation. However, its role in mature neurons remains poorly understood. This study investigates the impact of Msh2 loss on sensory processing in mice. Using electrophysiological and molecular assays, we identifiedsignificant deficits in cortical and thalamic sound processing in Msh2

Osteoarthritis (OA) is a complex disease associated with genetic, biological, and mechanical risk factors that act, in part, to alter chondrocyte homeostasis. Our recent exome sequencing studies identified a damaging genetic variant in COL6A3, a monomeric unit of collagen type VI and a distinguishing component of the pericellular matrix (PCM) of articular cartilage, a transducer of mechanical and biochemical signals for the chondrocyte. To study the effect of this genetic variant, human induced pluripotent stem cell (hiPSC)-derived chondrocytes, genetically edited to harbor the COL6A3 mutation, were used as an in vitro model to investigate chondrocyte mechanobiology and pathobiology. The COL6A3 …

2020-Current year OA Pubs

Somatic mutations in KRAS are a common driver of colorectal cancer (CRC) and present at different frequencies by race, sex, tumor site, ethnicity, and genetic similarity. Inherited germline variants may influence tumor somatic mutation frequency by altering mutation or DNA repair processes or altering cellular, immunological and/or microenvironmental responses after a mutation. We hypothesized that the germline genetic background modifies somatic KRAS mutation frequency in CRC. To test this, we performed a genome-wide association study (GWAS) in 7071 individuals with CRC, using KRAS mutation status as the phenotype. Single-nucleotide variants were chosen for validation analyses based on P values from …

Large-scale brain activity reflects changes in attention. To understand how, we tested a hypothesis that the geometry of neural dynamics on the cortical attractor landscape, or movement along its "hills and valleys", reflects attentional states. A dynamical systems model separating intrinsic dynamics from stimulus-driven influences was fit to fMRI data collected during rest, tasks, and movie-watching. Model simulations revealed a set of attractors aligned with canonical functional brain networks. The speed and direction of neural trajectories toward these attractors varied systematically with attentional states over time and across contexts. When participants were paying attention to effortful tasks, neural dynamics converged …

The inwardly rectifying potassium channel Kir7.1 is essential for the physiological function of diverse tissues, including the retinal pigment epithelium and the gestational myometrium. Loss-of-function mutations in KCNJ13, which encodes Kir7.1, or conditional ablation of Kir7.1 in the retinal pigment epithelium, lead to early-onset vision loss. Despite strong genetic evidence supporting Kir7.1 as a therapeutic target, its regulation by endogenous ligands-beyond phosphoinositides-remains poorly understood. Here, we report cryo-electron microscopy structures of human Kir7.1 in multiple functional states at resolutions ranging from 2.8 Å to 4.0 Å. These structures uncover the molecular basis of Kir7.1 modulation by PI
