Role of cardiolipin in proton transmembrane flux and localization.
Biophys J
January 2025
Laboratoire Jean Perrin, CNRS, Sorbonne Université, UMR 8237, Paris, France. Electronic address:
In eukaryotic cells, the phospholipid cardiolipin (CL) is a crucial component that influences the function and organization of the mitochondrial inner membrane. In this study, we examined its potential role in passive proton transmembrane flux using unilamellar vesicles composed of natural egg phosphatidylcholine (PC) alone or with the inclusion of 18 or 34 mol % CL. A membrane potential was induced by a potassium gradient, and oxonol VI dye was used to monitor membrane potential dissipation resulting from proton transmembrane efflux.

Copper is an essential but potential toxic micro-nutrient in rapeseed. So far, little is known about the mechanism of rapeseed Cu transport and detoxification. Here, we determined the function of Cu transporter, Brassica napus cell number regulator 6 (BnCNR6), in regulating Cu homeostasis.

Department of Radiology and Nuclear Medicine, Xuanwu Hospital, Capital Medical University, Beijing, China.
Background: Identifying DNA mismatch repair deficiency (MMRd) is important for prognosis risk stratification in patients with early-stage endometrial cancer (EC), but there is a notable absence of cost-effective and non-invasive preoperative assessment techniques. The study explored the co-reactivity pattern of glucose metabolism and blood perfusion in EC based on hybrid [F]fluorodeoxyglucose ([F]FDG) PET/dynamic contrast enhanced (DCE)-MRI to provide an imaging biomarker for identifying MMRd.
Methods: Patients with a history of postmenopausal bleeding and initially diagnosed with EC on ultrasound were recruited to perform a PET/DCE-MRI scan.
Taoren Honghua Decoction alleviates atherosclerosis by inducing autophagy and inhibiting the PI3K-AKT signaling pathway to regulate cholesterol efflux and inflammatory responses.

Department of Cardiology, Longhua Hospital, Shanghai University of Traditional Chinese Medicine, Shanghai, China. Electronic address:
Background: Taoren Honghua Decoction (THD) is a traditional Chinese formula known for enhancing blood circulation and demonstrating clinical efficacy in the treatment of cardiovascular and cerebrovascular diseases. However, the primary active components and the underlying mechanisms by which THD exerts its therapeutic effects on atherosclerosis (AS) remain insufficiently characterized.
Objective: This study aims to systematically validate the protective effects of THD on AS and elucidate its potential molecular mechanisms through an integrative approach involving network pharmacology, in vivo, and in vitro experiments.
Application of structural equation modelling to study complex "blue carbon" cycling in mangrove ecosystems.

Blue Carbon Lab, Deakin Marine Research and Innovation Centre, Deakin University, Burwood campus, 221 Burwood Hwy, VIC 3125, Australia; Centre for Nature Positive Solutions, Biosciences and Food Technology Discipline, School of Science, RMIT University, Melbourne, VIC 3000, Australia.
Article Synopsis
- Blue carbon cycling in mangrove ecosystems is more intricate than initially believed, prompting the use of structural equation modeling (SEM) for a deeper analysis.
- The study utilized data from the Indian Sundarban to illustrate how SEM effectively integrates different data types to understand CO fluxes in mangroves, including key interactions between the atmosphere, water, and soil.
- Findings indicate that atmospheric, water, and soil temperatures significantly drive CO emissions from mangrove ecosystems, demonstrating the utility of SEM in capturing complex biogeochemical cycles in blue carbon environments.
