Research Progress on Mechanism of Action of DHODH in Progression of Malignant Tumors
Dihydroorotate dehydrogenase (DHODH) is a flavin-dependent metabolic enzyme that oxidizes dihydroorotate acid to orotic acid in the de novo synthesis pathway of pyrimidine metabolism.

Residual OXPHOS is required to drive primary and metastatic lung tumours in an orthotopic breast cancer model [PDF]
BackgroundFast adaptation of glycolytic and mitochondrial energy pathways to changes in the tumour microenvironment is a hallmark of cancer. Purely glycolytic ρ0 tumour cells do not form primary tumours unless they acquire healthy mitochondria from their

mtDNA copy number: molecular diagnostics and mitochondrial-nuclear crosstalk in frailty and ageing
Quantitative assessment of mitochondrial DNA copy number is an emerging field of study in the diagnosis and evaluation of age-related pathology and frailty in the elderly, along with the assessment of other acute and chronic diseases that are often ...

Aging Is a Key Driver for Adult Acute Myeloid Leukemia
Acute myeloid leukemia (AML) is a classical age‐related hematologic malignancy, and a key driver of AML is aging, which profoundly regulates intrinsic factors such as genomic instability, epigenetic reprogramming, and metabolic dysregulation, and alters bone marrow microenvironment.

OXPHOS Defects Due to mtDNA Mutations: Glutamine to the Rescue!
Mutations in mtDNA associated with OXPHOS defects preclude energy harnessing by OXPHOS. The work of Chen et al. (2018) is previewed, reporting flux pathways of glutamine catabolism in mtDNA mutant cells yielding high-energy phosphates through substrate ...

Under NIR irradiation, PTCPP generates ROS to eliminate MRSA biofilms and promote M1 macrophage polarization for phagocytosis. After bacterial clearance, the material is phagocytosed by macrophages, shifting their polarization to M2 phenotype via metabolic reprogramming, which synergistically enhances anti‐infection therapy and wound healing.

Mitochondrial OxPhos: the integrator of the cellular metabolic status [PDF]
El sistema de fosforilación oxidativa (OXPHOS) es el único sistema en la célula animal cuyos componentes están codificados en dos genomas, el ADN mitocondrial (mtDNA) y el ADN nuclear (nDNA). El mtDNA es poliploide, de herencia materna y carece de un sistema de recombinación durante su replicación, cuyas consecuencias son una tasa de mutación un orden ...

Intrinsic OXPHOS limitations underlie cellular bioenergetics in leukemia
Currently there is great interest in targeting mitochondrial oxidative phosphorylation (OXPHOS) in cancer. However, notwithstanding the targeting of mutant dehydrogenases, nearly all hopeful ‘mito-therapeutics’ cannot discriminate cancerous from non ...

This diagram illustrates that night shift work disrupts circadian clock genes (like CLOCK, BMAL1) in both humans and mice. This disruption leads to mitochondrial dysfunction (imbalanced fusion/fission proteins) and increased oxidative stress, which is identified as the primary mechanism ultimately causing elevated blood pressure.

Increased liver content of DHA‐derived small lipid autacoids (i.e resolvin D1 and maresin 1) associates with enhanced mitochondrial oxidative phosphorylation, fatty acid β‐oxidation and bioenergetic metabolic flux. These features provide hepatic protection from steatotic, pro‐inflammatory and fibrogenic insults.
