MGlu5 Dependent Mitochondrial Translocation of PKCδ: A Mechanism Raising Astrocytic Oxidative Metabolism in Response to Extracellular Glutamate

open access: yesJournal of Neurochemistry, Volume 169, Issue 8, August 2025.
The observations suggest a new mechanism, the mGluR5/PKCδ/PDH axis by which extracellular glutamate can raise oxidative metabolism in astrocytes, in response to rapidly increasing energy demands, such as in the liver or skeletal muscle. It appears that the plethora of astrocytic mitochondria maintain only a basal level of oxidative metabolism during ...

Sexual Selection on Non‐Ornamental Traits Is Underpinned by Evidence of Genetic Constraints on Sex‐Biased Expression in Dusky Pipefish

open access: yesMolecular Ecology, Volume 34, Issue 15, August 2025.
ABSTRACT Species lacking distinct secondary sex characteristics, such as differences in size or morphology, are often thought to experience lower levels of sex‐specific selection in comparison to highly sexually dimorphic organisms. However, monomorphism in classic visible traits could be a result of genetic or physiological constraints that prevent ...

Vanadate effects on bone metabolism: fish cell lines as an alternative to mammalian in vitro systems [PDF]

open access: yes, 2007
Vanadate, one of the most relevant forms of vanadium in solution, has been associated with the regulation of various enzyme activities (e.g. phosphatases, ribonucleases, ATPases, etc.) and shown to exhibit important biological effects.

MsAREB1 enhances combined cold and saline–alkali stress tolerance by promoting ascorbic acid biosynthesis in alfalfa

open access: yesPlant Biotechnology Journal, Volume 23, Issue 8, Page 3349-3362, August 2025.
Summary Cold and saline–alkali stress are typical abiotic stresses on forage in middle and high latitudes, and they frequently occur simultaneously, decreasing the yield and quality of forage. Ascorbic acid plays an essential role in reactive oxygen species metabolism in response to abiotic stress.
