Summary: The study aimed to investigate the impact of propionate supply on mitochondrial dysfunction, oxidative stress, and apoptosis in calf hepatocytes under high FFA load. The results demonstrated that propionate supply could alleviate mitochondrial dysfunction, oxidative stress, and apoptosis by upregulating PGC-1 alpha in FFA-treated calf hepatocytes.

Summary: Excessive mitochondrial fission in podocytes is a critical feature of diabetic nephropathy. Mitochondria-associated endoplasmic reticulum membranes (MAMs) are suggested to be related to mitochondrial function, but their role in mitochondrial dynamics disorder in podocytes under diabetic conditions remains unknown.

Summary: This study aimed to investigate the protective effects of silibinin against cerebral ischemia-reperfusion injury in neuroblastoma N2a cells, as well as the mechanisms involved. The results showed that silibinin significantly reduced cell death, apoptotic rate, LDH, and ROS generation, and inhibited mitochondrial dysfunction and oxidative stress. However, the protective effects of silibinin were weakened when GAS6 was silenced.

Summary: miR-27b is highly expressed in endothelial cells and plays a crucial role in regulating inflammatory pathways, cell cycle, apoptosis, and mitochondrial oxidative imbalances. miR-27b mimic can counteract the cytotoxicity and inflammation caused by TNF-alpha, as well as restore mitochondrial function. Mechanistically, miR-27b targets FOXO1 to achieve its functions.

Summary: Ovarian dysfunction is a common cause of female infertility, which is influenced by genetic, autoimmune, and environmental factors. Granulosa cells play a role in regulating ovary function through their changes, including oxidative stress and excessive reactive oxygen species. miR-484 is highly expressed in ovarian oxidative stress models and aggravates granulosa cell dysfunction, leading to intensified ovarian oxidative stress injury. Additionally, LINC00958 acts as a competing endogenous RNA for miR-484 and forms a signaling axis with SESN2 under oxidative stress conditions, regulating mitochondrial functions and apoptosis in granulosa cells.

Summary: This paper investigates the impact of neutrophils on disseminated intravascular coagulation (DIC). The study shows that neutrophils can alleviate coagulopathy and prevent death from sepsis by releasing extracellular vesicles containing superoxide dismutase 2. The findings reveal an interaction between neutrophils and vascular endothelium that critically regulates coagulation in sepsis, which may have implications for the management of DIC.

Summary: This study investigated the effect of DLM on quail cerebrum neurons and found that DLM exposure induced histological changes, oxidative stress, and neurons apoptosis in quail cerebrum tissues. Furthermore, the study showed that DLM exposure also increased the expression of ER stress-related mRNA and decreased ATP content in quail cerebrum tissues, indicating ER stress and mitochondrial dysfunction as possible mechanisms for DLM-induced apoptosis of quail cerebrum neurons.

Summary: Dysfunctional mitochondria can have severe consequences on cell functions, especially in neurodegenerative diseases. The discovery of neuroglobin (NGB) as an endogenous neuroprotective protein provides potential for new therapeutic strategies, particularly in the context of mitochondrial homeostasis in neural pathologies.
