Robust 3D modeling reveals spatiosyntenic properties of animal genomes

iScience, 2023
Summary: Animal genomes are organized into chromosomes that are remarkably conserved in their gene content, forming distinct evolutionary units (synteny).

Protocol for an agent-based model of recombination in bacteria playing a public goods game

STAR Protocols, 2023
Summary: Agent-based models are composed of individual agents coded for traits, such as cooperation and cheating, that interact in a virtual world based on defined rules.

Differential fates of Kazald gene quartet: Ancestral roles in skeletogenesis and regeneration to putative innovations in fish and birds

iScience
Summary: Gene orthology inference across species is crucial to identify gains and losses of functions. The discovery in axolotl (Ambystoma mexicanum) of a regeneration-associated gene identified as either Kazald1 or Kazald2 led us to investigate its ...

Transcriptional effects of a positive feedback circuit in Drosophila melanogaster

BMC Genomics, 2017
Background Synthetic systems that use positive feedback have been developed to control human disease vectors and crop pests. The tTAV system, which has been deployed in several insect species, relies on a positive feedback circuit that can be inhibited ...

Evolutionary activation of acidic chitinase in herbivores through the H128R mutation in ruminant livestock

iScience, 2023
Summary: Placental mammals' ancestors were insectivores, suggesting that modern mammals may have inherited the ability to digest insects. Acidic chitinase (Chia) is a crucial enzyme hydrolyzing significant component of insects' exoskeleton in many ...

Oncogenic stress alters predator-prey interactions between a globally invasive and a native planaria species

iScience
Summary: Oncogenic pressures, factors that increase tumor risk, are intensifying with human-driven environmental change, yet their ecological effects remain mainly unquantified.

Genome structure and evolutionary history of frankincense producing Boswellia sacra

iScience, 2022
Summary: Boswellia sacra Flueck (family Burseraceae) tree is wounded to produce frankincense. We report its de novo assembled genome (667.8 Mb) comprising 18,564 high-confidence protein-encoding genes.

Evaluation of the Utility of Baseline Echocardiogram in Patients With Standard Risk Precursor B‐Lymphoblastic Leukemia

Pediatric Blood &Cancer, EarlyView.
Abstract Background A routine baseline echocardiogram is often obtained prior to anthracycline administration in children with cancer. The utility of baseline echocardiogram is unclear in patients with standard risk B‐cell acute lymphoblastic leukemia (SR B‐ALL) as their anthracycline cumulative dose is low.

Early genome erosion and internal phage-symbiont-host interaction in the endosymbionts of a cold-seep tubeworm

iScience, 2023
Summary: Endosymbiosis with chemosynthetic Gammaproteobacteria is widely recognized as an adaptive mechanism of siboglinid tubeworms, yet evolution of these endosymbionts and their driving forces remain elusive.

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

FEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.
