The contribution of metabolic theory to ecology
Ecological Monographs, Volume 95, Issue 3, August 2025.Abstract The metabolic theory of ecology (MTE) has been an important strand in ecology for almost a quarter of a century, renewing interest in the importance of body size and the role of energy. The core of the MTE is a hydrodynamic model of the vertebrate cardiovascular system that predicts allometric scaling of metabolic rate with exponents in the ...

Mass Spectrometry Reviews, Volume 44, Issue 3, Page 213-453, May/June 2025.Abstract The use of matrix‐assisted laser desorption/ionization (MALDI) mass spectrometry for the analysis of carbohydrates and glycoconjugates is a well‐established technique and this review is the 12th update of the original article published in 1999 and brings coverage of the literature to the end of 2022.

Planarians as a model to assess in vivo the role of matrix metalloproteinase genes during homeostasis and regeneration [PDF]
, 2013 Matrix metalloproteinases (MMPs) are major executors of extracellular matrix remodeling and, consequently, play key roles in the response of cells to their microenvironment.

Vertical Cancer Transmission via Asexual Fragmentation and Associated Cancer Prevalence
Evolutionary Applications, Volume 18, Issue 5, May 2025.ABSTRACT While sexual reproduction is a general feature of animals, fissiparity and budding are relatively uncommon modes of asexual reproduction by which a fragment from a parent becomes an independent organism. Unlike unitary development, tumor cells can be included in the detached fragment destined to become offspring.

Invertebrate Bile Acid‐Sensitive Ion Channels and Their Emergence in Bilateria
The FASEB Journal, Volume 39, Issue 8, 30 April 2025.This graphical abstract presents the evolutionary distribution and functional characteristics of bile acid‐sensing ion channels (BASICs) across bilaterians. A phylogenetic tree illustrates the presence of BASICs in diverse groups, extending beyond previously established mammalian findings.

, an -like gene, is essential for spermatid differentiation in the flatworm [PDF]
, 2009 Background Failure of sperm differentiation is one of the major causes of male sterility. During spermiogenesis, spermatids undergo a complex metamorphosis, including chromatin condensation and cell elongation. Although the resulting sperm morphology and

Muscular remodeling and anteroposterior patterning during tapeworm segmentation
Developmental Dynamics, Volume 253, Issue 11, Page 998-1023, November 2024.Abstract Background Tapeworms are parasitic flatworms that independently evolved a segmented body plan, historically confounding comparisons with other animals. Anteroposterior (AP) patterning in free‐living flatworms and in tapeworm larvae is associated with canonical Wnt signaling and positional control genes (PCGs) are expressed by their musculature

Non‐senescent species are not immortal: Stress and decline in two planaria species
Journal of Animal Ecology, Volume 93, Issue 11, Page 1722-1735, November 2024.Our work offers an important contribution to understanding how species with negligible or negative senescence respond to variation in available resources that could result in suboptimal conditions of stress. Using potentially immortal planaria, with unique life histories, as our system we provide novel insight into this under‐represented area of ...

Evolution of the Cdk4/6–Cdkn2 system in invertebrates
Genes to Cells, Volume 29, Issue 11, Page 1037-1051, November 2024.Hypothesis on the evolution of the Cdkn2 locus. (a) Loss of Cdkn2 occurred multiple times. (b) Evolution of microsynteny at the Cdkn2 locus. Cdkn2e is a hypothetical transient gene. Abstract The cell cycle is driven by cyclin‐dependent kinases (Cdks). The decision whether the cell cycle proceeds is made during G1 phase, when Cdk4/6 functions.

Rapid Communications in Mass Spectrometry, Volume 38, Issue 17, September 2024.Rationale Matrix‐assisted laser desorption/ionisation‐mass spectrometry imaging (MALDI‐MSI) is a powerful label‐free technique for biomolecule detection (e.g., lipids), within tissue sections across various biological species. However, despite its utility in many applications, the nematode Caenorhabditis elegans is not routinely used in combination ...
