Adenine nucleotide translocator and ATP synthase cooperate in mediating the mitochondrial permeability transition.
J Physiol
January 2025
Department of Biomedical Sciences, University of Padova, Padova, Italy.
The permeability transition (PT) is a permeability increase of the mitochondrial inner membrane causing mitochondrial swelling in response to matrix Ca. The PT is mediated by regulated channel(s), the PT pore(s) (PTP), which can be generated by at least two components, adenine nucleotide translocator (ANT) and ATP synthase. Whether these provide independent permeation pathways remains to be established.

Department of Pharmacy, The Second Xiangya Hospital, Central South University, Changsha, 410011, Hunan, China.
Purpose: Doxorubicin (Dox) is a classic anthracycline chemotherapy drug with cause cumulative and dose-dependent cardiotoxicity. This study aimed to investigate the potential role and molecular mechanism of phenylacetylglutamine (PAGln), a novel gut microbiota metabolite, in Dox-induced cardiotoxicity (DIC).
Methods: DIC models were established in vivo and in vitro, and a series of experiments were performed to verify the cardioprotective effect of PAGln.
Narciclasine attenuates sepsis-associated acute kidney injury through the ESR1/S100A11 axis.

Department of Emergency and Critical Care Medicine, Affiliated Hospital of Integrated Traditional Chinese and Western Medicine, Nanjing University of Chinese Medicine, Nanjing, Jiangsu, 210028, People's Republic of China.
Narciclasine (Ncs) was effective in sepsis management due to its antioxidant properties. The present study dissected the protective effects of Ncs against sepsis-associated acute kidney injury (SA-AKI) and the molecular mechanisms. The SA-AKI mice were developed using cecum ligation and puncture and pretreated with Ncs and adenoviruses.

December 2024
Department of Biochemistry, Faculty of Pharmacy, Ankara University, Ankara, Türkiye.
Background: Bronchopulmonary dysplasia (BPD) is a chronic lung disease in premature infants caused by an imbalance between lung injury and lung repair in the developing immature lungs of the newborn. Pulmonary inflammation is an important feature in the pathogenesis of BPD. The aim of this study was to evaluate the relationship between the inflammatory microenvironment and the levels of visfatin and nesfatin-1, which are among the new adipocytokines, in BPD patients.

Neurosteroids play an important role as endogenous neuromodulators that are locally produced in the central nervous system and rapidly change the excitability of neurons and the activation of microglial cells and astrocytes. Here we review the mechanisms of synthesis, metabolism, and actions of neurosteroids in the central nervous system. Neurosteroids are able to play a variety of roles in the central nervous system under physiological conditions by binding to membrane ion channels and receptors such as gamma-aminobutyric acid type A receptors, Nmethyl- D-aspartate receptors, L- and T-type calcium channels, and sigma-1 receptors.
