The accumulation of adaptive mutations is essential for survival in novel environments. However, clonal populations with a high mutational supply, the power natural selection expected to be limited. This due interference - competition clones carrying different beneficial which leads loss many small effect and fixation large ones.

Abstract Cancer immunoediting is a dynamic process of crosstalk between tumor cells and the immune system. Herein, we explore fast zebrafish xenograft model to investigate innate contribution this process. Using multiple breast colorectal cancer cell lines zAvatars, find that some are cleared (regressors) while others engraft (progressors) in xenografts. We focus on two human derived from same patient show contrasting engraftment/clearance profiles. polyclonal xenografts mimic intra-tumor...

The 2022 multicountry mpox outbreak concurrent with the ongoing Coronavirus Disease 2019 (COVID-19) pandemic further highlighted need for genomic surveillance and rapid pathogen whole-genome sequencing. While metagenomic sequencing approaches have been used to sequence many of early infections, these methods are resource intensive require samples high viral DNA concentrations. Given atypical clinical presentation cases associated uncertainty regarding load across both course infection...

Under cellular stress conditions, transcription machinery fails to identify site continues transcribing beyond gene boundaries, phenomenon designated as readthrough. However, prevalence impact this healthy human tissues remain unexplored.

Developmental biology aims to understand how the dynamics of embryonic shapes and organ functions are encoded in linear DNA molecules. Thanks recent progress genomics imaging technologies, systemic approaches now used parallel with small-scale studies establish links between genomic information phenotypes, often described at subcellular level. Current model organism databases, however, do not integrate heterogeneous data sets different scales into a global view developmental program. Here,...

Genomics-informed pathogen surveillance strengthens public health decision-making, playing an important role in infectious diseases' prevention and control. A pivotal outcome of genomics is the identification genetic clusters their characterization terms geotemporal spread or linkage to clinical demographic data. This task often consists visual exploration (large) phylogenetic trees associated metadata, being time-consuming difficult reproduce.

Drosophila syncytial nuclear divisions limit transcription unit size of early zygotic genes. As mitosis inhibits not only transcription, but also pre-mRNA splicing, we reasoned that constraints on splicing were likely to exist in the embryo, being avoidance a possible explanation why most genes are intronless. We isolated two mutant alleles for subunit NTC/Prp19 complexes, which specifically impaired maternally encoded transcripts. hypothesized requirements efficiency vary during...

Formation of the vertebrate postcranial body axis follows two sequential but distinct phases. The first phase generates pre-sacral structures (the so-called primary body) through activity primitive streak on axial progenitors within epiblast. embryo then switches to generate secondary (post-sacral structures), which depends in tail bud. Here we show that mammalian bud is generated an independent functional developmental module, concurrent functionally different from generating body. This...

Abstract Colorectal cancer (CRC) is a highly diverse disease, where different genomic instability pathways shape genetic clonal diversity and tumor microenvironment. Although intra-tumor heterogeneity has been characterized in primary tumors, its origin consequences CRC outcome not fully understood. Therefore, we assessed intra- inter-tumor of prospective cohort 136 samples. We demonstrate that forged by asynchronous forms molecular alterations, mutational chromosomal collectively boost...

Cognitive judgement bias in decision-making under ambiguity occurs both animals and humans, with some individuals interpreting ambiguous stimulus as positive (optimism) others negative (pessimism). We hypothesize that is a personality trait pessimistic would be more reactive to stressors therefore susceptible stress-related diseases than optimistic ones. Here, we show zebrafish judgment consistent behavioral over time, fish express phenotype-specific neurogenomic responses stress....
