BMC Genomics, 2007 Background: Schistosoma mansoni is a blood helminth parasite that causes schistosomiasis, a disease that affects 200 million people in the world. Many orthologs of known mammalian genes have been discovered in this parasite and evidence is accumulating ...

The FEBS Journal, EarlyView.DNA damage in the tardigrade Hypsibius exemplaris elicits distinct cellular outcomes depending on replication status. While non‐replicating cells tolerate genotoxic stress, constitutively replicating cells undergo irreversible replication failure upon DNA damage, leading to loss of tissue homeostasis, fat depletion, sterility, and organismal death ...

BMC Evolutionary Biology, 2019 Background The Scalidophora (Kinorhyncha, Loricifera and Priapulida) have an important phylogenetic position as early branching ecdysozoans, yet the architecture of their nervous organ systems is notably underinvestigated.

Coevolution of the CDCA7-HELLS ICF-related nucleosome remodeling complex and DNA methyltransferases
eLife, 2023 5-Methylcytosine (5mC) and DNA methyltransferases (DNMTs) are broadly conserved in eukaryotes but are also frequently lost during evolution. The mammalian SNF2 family ATPase HELLS and its plant ortholog DDM1 are critical for maintaining 5mC. Mutations in

Evaluating 18S Phylogenetic Placement Accuracy to Uncover Hidden Diversity in Non‐Bilaterian Animals
Environmental DNA, Volume 8, Issue 4, July‐August 2026.We assembled the largest curated non‐bilaterian 18S reference dataset and demonstrate that barcode choice strongly influences phylogenetic placement accuracy. Full‐length 18S provides the most robust framework for biodiversity discovery, recovering previously unknown non‐bilaterian lineages, whereas V9 should be interpreted with caution. ABSTRACT Small

Open Biology, 2023 The neuropeptide pigment-dispersing factor (PDF) plays a pivotal role in the circadian clock of most Ecdysozoa and is additionally involved in the timing of seasonal responses of several photoperiodic species.

Papers in Palaeontology, Volume 12, Issue 4, July/August 2026.Abstract Cambrian Series 2 represents a key interval for documenting the evolution and diversification of early biomineralized skeletal animals. In this interval, small shelly fossils (SSF) provide an essential archive for regional biostratigraphy and intercontinental correlation.

At the Edge of Survival: Exploring the Frontiers of Tardigrade Extreme Stress Tolerance
Molecular Ecology, Volume 35, Issue 14, July 2026.ABSTRACT Tardigrades possess extraordinary resilience to extreme environmental conditions, including near‐complete desiccation, severe levels of radiation, the vacuum of space and extreme sub‐zero temperatures. Despite significant interest in their survival strategies, the molecular mechanisms underlying their survival during extreme stresses have ...

EF-hand proteins in onychophorans as compared to tardigrades and other ecdysozoans
Journal of Limnology, 2013 To learn more about the regulation of muscle contraction in the structural and functionally different muscles in Ecdysozoa, we have analysed the four EF-hand proteins calmodulin (CaM), troponin C (TnC), essential myosin light chain (eMLC) and regulatory ...
