Brain‐Derived Neurotrophic Factor (BDNF) and Sex Differences in Metabolic Regulation

Journal of Neurochemistry, Volume 169, Issue 10, October 2025.
Brain‐derived neurotrophic factor (BDNF) is expressed in the hypothalamus of both female and male mice (left‐hand side of the panel); however, it exerts distinct functions in either sex, explaining some sexually dimorphic phenotypes in mice and humans (right‐hand side of the panel).

Phylogenomics and revised classification of Lymexyloidea and Tenebrionoidea (Coleoptera: Polyphaga: Cucujiformia)

Systematic Entomology, Volume 50, Issue 4, Page 794-812, October 2025.
Using a large‐scale phylogenomic dataset, we provide the robustly supported phylogeny of the wider Tenebrionoid clade, with Lymexyloidea sister to the mordelloid clade (Mordellidae and Ripiphoridae) + remaining Tenebrionoidea. Lymexyloidea contained two newly circumscribed families, each of them with two subfamilies, and both Mordellidae and ...

Abundance of Maternal Mitochondrial Genome Is Dispensable up to the Mitochondrial Genome Activation in Post‐Implantation Embryos

The FASEB Journal, Volume 39, Issue 17, 15 September 2025.
A mouse model of Tfam conditional knock‐out (TfamloxP/loxP; Zp3‐Cre) produces mtDNA‐depleted eggs. An abundance of mitochondrial mass is maintained through fission during oocyte growth and enables egg fertilization and blastocyst formation. Although embryonic genome activation may compensate for the maternal knock‐out in the two‐cell stage, the ...
