In light of the disappointing termination of clinical trials with potent complex I inhibitors, such as IACS-010759, justification for oxidative phosphorylation inhibitors and mitochondrial targeting strategies has been called into question. Consideration of these agents’ potency, tissue selectivity and toxicity demonstrate what lessons can be learned from this failure and where new opportunities lie.

Background: Mitochondrial E3 ubiquitin ligase (MARCH5) as an important regulator in maintaining mitochondrial function. Our aims were to investigate the role and mechanism of MARCH5 in aortic valve calcification.
Methods: Human aortic valves, both calcified and non-calcified, were analyzed for MARCH5 expression using western blot.

Introduction: Chronic inflammation leading to implant failure present major challenges in orthopedics, dentistry, and reconstructive surgery. Titanium alloys, while widely used, often provoke inflammatory complications. Zinc-doped calcium phosphate (CaP) coatings offer potential to enhance implant integration by improving corrosion resistance, bioactivity, and immunocompatibility.

Rare inherited diseases caused by mutations in the copper transporters (CTR1) or induce copper deficiency in the brain, causing seizures and neurodegeneration in infancy through poorly understood mechanisms. Here, we used multiple model systems to characterize the molecular mechanisms by which neuronal cells respond to copper deficiency. Targeted deletion of CTR1 in neuroblastoma cells produced copper deficiency that produced a metabolic shift favoring glycolysis over oxidative phosphorylation.

Chronic innate immune activation in the central nervous system (CNS) significantly contributes to neurodegeneration in progressive multiple sclerosis (MS). Using multiple experimental autoimmune encephalomyelitis (EAE) models, we discovered that NLRX1 protects neurons in the anterior visual pathway from inflammatory neurodegeneration. We quantified retinal ganglion cell (RGC) density and optic nerve axonal degeneration, gliosis, and T-cell infiltration in Nlrx1 and wild-type (WT) EAE mice and found increased RGC loss and axonal injury in Nlrx1 mice compared to WT mice in both active immunization EAE and spontaneous opticospinal encephalomyelitis (OSE) models.
