Domain‐Shuffling in the Evolution of Cyclostomes and Gnathostomes

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 344, Issue 2, Page 59-79, March 2025.
We addressed the potential roles of domain‐shuffling origin genes (DSO‐Gs) in the evolution of early vertebrates. Through comparative genome analysis of 22 metazoans, including four cyclostomes, we identified DSO‐Gs before and after the divergence of cyclostomes and gnathostomes, and suggest domain shuffling as a key mechanism in vertebrate early ...

Evolution of the Cdk4/6–Cdkn2 system in invertebrates

open access: yesGenes 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.

Protein tyrosine phosphatase 1B (PTP1B) function, structure, and inhibition strategies to develop antidiabetic drugs

open access: yesFEBS Letters, Volume 598, Issue 15, Page 1811-1838, August 2024.
This Review presents the main advances in the study of PTP1B since it was first isolated, and recent contextual information related to this protein. Furthermore, we provide an overview of the role of PTP1B in diabetes and obesity, and the challenges of developing selective, effective, potent, bioavailable, and cell‐permeable compounds that can inhibit ...

Molecular mechanisms of perilipin protein function in lipid droplet metabolism

open access: yesFEBS Letters, Volume 598, Issue 10, Page 1170-1198, May 2024.
Lipid droplets (LDs) are important for the storage of energy and lipid components. The perilipin family in mammals includes five proteins (PLIN1 to PLIN5), all of which are abundant on the surface of LDs in different tissues and play a role in LD stability and degradation by lipases.

Ein neues kulturverfahren für trichoplax adhaerens f. e. schulze / A new cultural method for trichoplax adhaerens f. e. schulze

open access: yesZeitschrift für Naturforschung C, 1983
The primitive metazoon, Trichoplax adhaerens (Placozoa), can easily be cultivated with Nauplius larvae of the brine shrimp, Artemia salina, killed by heating, as food ...

Beauty in the beast – Placozoan biodiversity explored through molluscan predator genomics

open access: yesEcology and Evolution, Volume 14, Issue 4, April 2024.
Previous assumptions about the primary habitat of Placozoa are challenged, and their broader diversity beyond disc‐shaped grazers in coastal waters is revealed. The discovery of placozoan‐predatory sea slugs prompts consideration of a new ecological niche: seafloor sediment interstices.

Proteoglycans in mechanobiology of tissues and organs: Normal functions and mechanopathology

open access: yesProteoglycan Research, Volume 2, Issue 2, April-June 2024.
Abstract Proteoglycans (PGs) are a diverse class of glycoconjugates that serve critical functions in normal mechanobiology and mechanopathology. Both the protein cores and attached glycosaminoglycan (GAG) chains function in mechanically sensitive processes, and loss of either can contribute to development of pathological conditions. PGs function as key

Importance of fatty acid binding proteins in cellular function and organismal metabolism

open access: yesJournal of Cellular and Molecular Medicine, Volume 28, Issue 5, March 2024.
Abstract Fatty acid binding proteins (Fabps) are small soluble proteins that are abundant in the cytosol. These proteins are known to bind a myriad of small hydrophobic molecules and have been postulated to serve a variety of roles, yet their precise functions have remained an enigma over half a century of study.

DNA Content and Fragmentation of the Egg Nucleus of Trichoplax adhaerens

open access: yesZeitschrift für Naturforschung C, 1981
Abstract Under culture conditions the egg nucleus of Trichoplax adhaerens reaches an unusually high and variable DNA content. Before the "fertilization membrane" is formed, the nucleus undergoes fragmentation. It is assumed that culture conditions differ from natural conditions by preventing the switch-over from the S-phase to the G 2 ...
