- Type 2 (T2) inflammation is a defining feature of asthma and associated with epithelial dysfunction, including goblet cell metaplasia and ciliary loss. Here, we investigated whether T2 inflammation and associated 15 lipoxygenase-1 (15LO1) activity alters mitochondrial metabolism in airway epithelial cells (AECs) and contributes to disease pathophysiology. Freshly isolated AECs from T2-high asthmatic participants exhibited increased oxygen consumption rates (OCR), including elevated basal respiration and proton leak, alongside reduced coupling efficiency compared to T2-low participants. These functional changes were accompanied by increased expression of electron transport chain (ETC) proteins, worse lung function and epithelial phenotypic changes. In vitro, IL-13 stimulation of differentiated AECs recapitulated these findings, inducing higher OCR, increased ETC protein levels, and enhanced proton leak while paradoxically reducing intracellular ATP. These metabolic alterations are associated with increased uncoupling protein 2 (UCP2) expression and goblet cell differentiation. Mechanistically, 15LO1 emerged as a key regulator, as ALOX15 knockdown or pharmacologic inhibition reduced OCR parameters, ETC protein expression, UCP2, and goblet cell markers, without effect on ATP levels, suggesting additional regulatory mechanisms. Collectively, these findings identify a metabolic axis linking T2 inflammation, mitochondrial dysfunction, and airway epithelial metabolism, while highlighting 15LO1-driven mitochondrial uncoupling as a potential therapeutic target in asthma. . - Source: PubMed

While the requirement of active mitochondria for steroid synthesis is well-established, the hormonal regulation of genes governing mitochondrial function remains poorly understood. This study investigated whether angiotensin II (Ang II) and the cAMP/PKA pathway modulate the expression of key regulatory factors involved in mitochondrial biogenesis and redox status in the human adrenocortical H295R cell line. Using real-time qPCR and Western blot, we show that Ang II and 8Br-cAMP-a permeant analog of cAMP-modulate NRF-1, Nrf2, UCP2, and ANT1 impacting on mitochondrial biogenesis, antioxidant defense, and respiratory activity. These molecular changes correlated with increased mitochondrial membrane polarization, as confirmed by MitoTracker red staining. Interestingly, Ang II stimulation promoted a time-dependent increase in TFAM levels, a key transcription factor in mitochondria, which correlates with the increase in mitochondrial DNA (mtDNA) content. The rate of oxygen consumption (OCR) and mitochondrial parameters were determined, with results showing that Ang II led to a significant increase in basal and maximum respiration, ATP production, and proton leak. These findings suggest that hormone stimulation favors mitochondrial activity, thereby enhancing the bioenergetic capacity of adrenocortical cells. Furthermore, treatment with the uncoupler CCCP triggered a retrograde signaling response, upregulating nuclear-encoded mitochondrial genes to counteract mitochondrial membrane depolarization. Our findings demonstrate for the first time that hormonal signals directly modulate the mitochondrial genetic program in H295R human adrenocortical cells, optimizing the bioenergetic platform required for efficient steroidogenic function. - Source: PubMed

Here we develop NAD-genipin nanomedicine for metabolic balance (NGB), a physiologically adaptive nanomedicine with staged intracellular release. In a mouse myocardial infarction model, NGB preferentially accumulates in ischemic myocardium, rapidly replenishes nicotinamide adenine dinucleotide (NAD) and subsequently provides mitochondria-associated sustained NAD-genipin exposure. This phase-linked delivery limits early mitochondrial stress, apoptosis and inflammation and later restores coordination between oxidative phosphorylation, glycolysis and fatty-acid utilization. Mechanistically, NGB supports sirtuin-1-associated oxidative metabolism and suppresses sustained upregulation of the mitochondrial uncoupling protein 2 (UCP2). In hypoxic cardiomyocytes, UCP2 knockdown plus NAD supplementation partially reproduces the NGB metabolic phenotype, whereas UCP2 overexpression and sirtuin 1 inhibition reverse distinct components of NGB-mediated respiratory and glycolytic recovery. NGB thereby reduces fibrosis and ventricular remodeling and preserves cardiac function, supporting temporally coordinated metabolic intervention after myocardial infarction. - Source: PubMed

White Emily LDay Emily AAppleton C ThomasGrol Matthew WBeier Frank - Hypoxia has therapeutic potential, but global hypoxia is toxic. Inducing safe, cell-specific hypoxia remains a clinically unmet need. We hypothesized that small-molecule-augmented oxygen consumption in adjacent cells induces neuron-specific hypoxia, representing a safe ischemic stroke strategy that mimics neural-directed developmental neovascularization. Using single-cell sequencing, a hypoxic probe, and knockout mice, we showed that ADT-OH (an active metabolite of a hepatoprotective drug) targeted sulfide-quinone oxidoreductase (SQR) to increase aerobic respiration in microglia/macrophages, thereby generating neuron-specific hypoxia after cerebral ischemia. Neuronal hypoxia promoted functional angiogenesis by specifically stabilizing hypoxia-inducible factor to upregulate the expression of neuron-derived vascular endothelial growth factor, supporting a neural-directed angiogenic mechanism. ADT-OH also restored the blood-brain barrier (BBB) via microglial/macrophage SQR. Notably, microglia/macrophage UCP2, the downstream mediator of SQR, was required for ADT-OH-induced BBB repair but not angiogenesis. Mechanistically, ADT-OH targeted UCP2 to increase Wnt/β-catenin signaling, which has been shown to mediate developmental BBB formation. In summary, one small molecule targeting SQR achieves therapeutic cell-specific hypoxia. - Source: PubMed
