Perception of without infection induces in .

pathogenic susceptibility is influenced by the worm's detection of its environment and its capacity to resist and resolve damage following infection. Here, we use a model where worms can sense, but not ingest, the pathogen (EF) We identify that perception of EF without infection induces the stress-response gene further identify that neural and intestinal signaling genes are necessary for induction without active infection. Finally, we show that overexpression is sufficient to extend lifespan with EF exposure, while KO is not detrimental, suggesting that additional expression benefits worms in this condition.

TAD evolutionary and functional characterization reveals diversity in mammalian TAD boundary properties and function.

Topological associating domains (TADs) are self-interacting genomic units crucial for shaping gene regulation patterns. Despite their importance, the extent of their evolutionary conservation and its functional implications remain largely unknown. In this study, we generate Hi-C and ChIP-seq data and compare TAD organization across four primate and four rodent species and characterize the genetic and epigenetic properties of TAD boundaries in correspondence to their evolutionary conservation.

Epimorphic regeneration in the mammalian tympanic membrane.

Adult mammals are generally believed to have limited ability to regenerate complex tissues and instead, repair wounds by forming scars. In humans and across mammalian species, the tympanic membrane (TM) rapidly repairs perforations without intervention. Using mouse models, we demonstrate that the TM repairs itself through a process that bears many hallmarks of epimorphic regeneration rather than typical wound healing.

Megaloblastosis: from morphos to molecules.

Objective: Megaloblastosis (i.e., megaloblastic transformation of erythroid precursor cells in the bone marrow) is the cytomorphological hallmark of megaloblastic anemia resulting from vitamin B12 and folate deficiency.
