Ammonia Metabolism in the Aging Liver: Emerging Mechanistic Insights

open access: yesAging Cell, Volume 25, Issue 8, August 2026.
Liver aging may weaken ammonia‐detoxification reserve by disrupting mitochondrial ureagenesis, GS‐mediated scavenging, glutamine metabolism, and metabolic zonation. This emerging framework links impaired nitrogen handling to potential hepatic stress amplification and systemic crosstalk, while highlighting the need for direct validation in physiological

Activation of mitochondrial CPS1 promotes dormant ovarian follicle activation via arginine elevation and the mTORC1 pathway

open access: yesFrontiers in Cell and Developmental Biology
BackgroundCarbamoyl phosphate synthetase 1 (CPS1) is a mitochondrial ligase essential for urea production, catalyzing the formation of carbamoyl phosphate from ammonia in a reaction requiring the allosteric activator N acetyl L glutamate (NAG).

Phytoplasma Effector SJP8 Suppresses Host Immunity by Promoting the Degradation of ZjMYB15 and ZjMYB86‐like to Perturb Jasmonic Acid and Hydrogen Peroxide Homeostasis in Jujube

open access: yesMolecular Plant Pathology, Volume 27, Issue 7, July 2026.
SJP8 suppresses plant immunity by perturbing JA and H2O2 homeostasis via the SJP8‐ZjMYB15/ZjMYB86‐like‐ZjJAIPHX1/ZjPOD43 module, leading to dwarfism and chlorosis. ABSTRACT ‘Candidatus Phytoplasma ziziphi’ infection causes severe damage to jujube (Ziziphus jujuba), inducing symptoms such as branch clustering, dwarfism, chlorosis and phyllody, leading ...
