Abstract As biodiversity loss outpaces recovery, conservationists are increasingly turning to novel tools for preventing extinction, including cloning and in vitro gametogenesis of biobanked cells. However, restoration populations can be hindered by low genetic diversity deleterious load. The persistence the northern white rhino ( Ceratotherium simum cottoni ) now depends on cryopreserved cells 12 individuals. These banked genomes have higher than southern rhinos C. s. ), a sister subspecies that successfully recovered from severe bottleneck, but potential impact load is unknown. We estimated how demographic history has shaped genome‐wide nine 13 rhinos. bottleneck left with more fixed homozygous alleles longer runs homozygosity, whereas retained masked heterozygosity. To gauge fitness population restored cells, we simulated recovery using as benchmark viable population. Unlike traditional restoration, cell‐derived founders reintroduced subsequent generations boost lost relieve inbreeding. In simulations repeated reintroduction into population, cost remained lower borne Without reintroductions, rapid growth (>20–30% per generation) would needed maintain comparable fitness. Our results suggest inbreeding depression not necessarily barrier demonstrate relieves some constraints conventional limited founder pool. Established conservation methods protect healthy will remain paramount, emerging technologies hold promise bolster these combat extinction crisis.

Machine Learning-based scoring and classification of genetic variants aids the assessment clinical findings is employed to prioritize in diverse studies analyses. Combined Annotation-Dependent Depletion (CADD) one first methods for genome-wide prioritization across different molecular functions has been continuously developed improved since its original publication. Here, we present our most recent release, CADD v1.7. We explored integrated new annotation features, among them state-of-the-art protein language model scores (Meta ESM-1v), regulatory variant effect predictions (from sequence-based convolutional neural networks) sequence conservation (Zoonomia). evaluated version on data sets derived from ClinVar, ExAC/gnomAD 1000 Genomes variants. For coding effects, tested 31 Deep Mutational Scanning (DMS) ProteinGym and, prediction, used saturation mutagenesis reporter assay promoter enhancer sequences.

Thousands of genomic regions have been associated with heritable human diseases, but attempts to elucidate biological mechanisms are impeded by an inability discern which positions functionally important. Evolutionary constraint is a powerful predictor function, agnostic cell type or disease mechanism. Single-base phyloP scores from 240 mammals identified 3.3% the genome as significantly constrained and likely functional. We compared annotation, association studies, copy-number variation, clinical genetics findings, cancer data. Constrained enriched for variants that explain common heritability more than other functional annotations. Our results improve variant annotation also highlight regulatory landscape still needs be further explored linked disease.

Human accelerated regions (HARs) are conserved genomic loci that evolved at an rate in the human lineage and may underlie human-specific traits. We generated HARs chimpanzee with automated pipeline alignment of 241 mammalian genomes. Combining deep learning chromatin capture experiments neural progenitor cells, we discovered a significant enrichment topologically associating domains containing variants change three-dimensional (3D) genome organization. Differential gene expression between humans chimpanzees these suggests rewiring regulatory interactions neurodevelopmental genes. Thus, comparative genomics together models 3D folding revealed enhancer hijacking as explanation for rapid evolution HARs.

Abstract Chemoreception – the ability to smell and taste is an essential sensory modality of most animals. The number type chemical stimuli that animals can perceive depends primarily on diversity chemoreceptors they possess express. In vertebrates, six families G protein-coupled receptors form core their chemosensory system, olfactory/pheromone receptor gene OR , TAAR V1R V2R T1R T2R . Here, we study vertebrate chemoreceptor repertoire its evolutionary history. Through examination 1,527 genomes, uncover substantial differences in composition across vertebrates. We show are co-evolving, highly dynamic, characterized by lineage-specific expansions (for example, tetrapods; teleosts; mammals; amphibians) losses. Overall, amphibians, followed mammals, clades with largest repertoires. While marine tetrapods feature a convergent reduction numbers, genes correlates habitat mammals birds migratory behavior birds, diet aquatic environment fish.

Obesity is a common, serious, and costly disease. More than 1 billion people worldwide are obese—650 million adults, 340 adolescents, 39 children. The WHO estimates that, by 2025, approximately 167 people—adults children—will become less healthy because they overweight or obese. Obesity-related conditions include heart disease, stroke, type 2 diabetes, certain types of cancer.
