Article Abstract
Metabolic reprogramming drives inflammatory activity in macrophages, including microglia, with Krebs cycle (KC) intermediates playing a crucial role as signaling molecules. Here, we show that the bioenergetic profile of LPS-activated human microglialclone 3 cell line (HMC3) is characterized by high levels of glycolysis and mitochondrial (mt) respiration, and the treatment with KC derivatives, namely dimethyl-fumarate (DMF) and itaconate (ITA), almost restores normal metabolism. However, despite comparable bioenergetic and anti-inflammatory effects, the mt hyper-activity was differentially modulated by DMF and ITA. DMF normalized complex I activity, while ITA dampened both complex I and II hyper-activity counteracting oxidative stress more efficiently.

In recent years, there has been a rapid increase in the incidence of thyroid carcinoma (TC). Our study focuses on the regulatory effect of circular RNAs on metabolism of TC, aiming to provide new insights into the mechanisms of progression and a potential therapeutic target for TC. In this study, we identified high expression levels of circPSD3 in TC tissues through RNA sequencing.

The low-carbon strategy mandates the sustainable remediation of hexavalent chromium (Cr(VI)) contamination, driving the demand for efficient eco-adsorbents. However, current research prioritizes adsorption performance, neglecting environmental trade-offs and quantum chemical mechanisms of Cr(VI) adsorption. Here, we pioneered the first density functional theory (DFT) exploration of Cr(VI) adsorption mechanisms across chitosan (CS), polydopamine (PDA), UiO-66-NH, and polyethylenimine.

Reduced mitochondrial quality and quantity in tumors is associated with dedifferentiation and increased malignancy. However, it remains unclear how to restore mitochondrial quantity and quality in tumors and whether mitochondrial restoration can drive tumor differentiation. Our study shows that restoring mitochondrial function using retinoic acid (RA) to boost mitochondrial biogenesis and a mitochondrial uncoupler to enhance respiration synergistically drives neuroblastoma differentiation and inhibits proliferation.

B complex vitamins, a group of eight water-soluble vitamins, play interconnected roles in maintaining nervous system health. Thiamine (B1), riboflavin (B2), and niacin (B3) are essential as co-enzymes in numerous metabolic reactions related to energy production. Thiamine is involved in the Krebs cycle, riboflavin in the electron transport chain, and niacin plays a key role in both glycolysis and the Krebs cycle.

Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is characterized by unexplained fatigue, post-exertional malaise (PEM), and cognitive dysfunction. ME/CFS patients often report a prodrome consistent with infection. We present a multi-omics analysis based on plasma metabolomic and proteomic profiling, and immune responses to microbial stimulation, before and after exercise.
