Obesity-Related Mitochondrial Analysis Service
InquiryObesity remains a complex, multifactorial metabolic condition characterized by excessive adipose tissue accumulation and systemic metabolic dysfunction. At the cellular level, mitochondria serve as the central hubs for energy homeostasis, lipid oxidation, and intracellular signaling. In obese states, nutrient overload disrupts mitochondrial dynamics, leading to impaired oxidative phosphorylation, elevated reactive oxygen species (ROS) production, compromised mitochondrial biogenesis, and altered organelle architecture across key metabolic tissues—including white and brown adipose tissue, skeletal muscle, and the liver.
Preclinical Mitochondrial Bioenergetics & Analysis Services for Obesity Research
Understanding these organelle-level perturbations in preclinical research requires robust, highly specialized analytical approaches. Protheragen provides a comprehensive portfolio of preclinical obesity-related mitochondrial analysis services designed to accelerate drug discovery, biomarker identification, and mechanistic research. By combining high-purity organelle isolation with advanced multi-omics, structural imaging, and real-time bioenergetic profiling, our preclinical platform enables researchers to dissect the precise role of mitochondrial dysfunction in metabolic disease progression without clinical trial dependencies.
Core Technologies
To evaluate mitochondrial health and function under high-fat, nutrient-dense conditions, Protheragen leverages an integrated suite of advanced technologies:
Real-time quantitative assessment of oxygen consumption rates (OCR), electron transport chain (ETC) complex activities, and mitochondrial membrane potential (△Ψm) in isolated organelles or intact preclinical tissue models.
Specialized protocols for isolating intact, functionally active mitochondria from lipid-rich tissues, eliminating cytoplasmic and extracellular contamination.
Quantitative ultrastructural visualization to assess mitochondrial cristae density, matrix integrity, swelling, and network morphology.
Specialized Next-Generation Sequencing (NGS) for mitochondrial DNA (mtDNA) heteroplasmy and copy number, paired with high-throughput liquid chromatography-mass spectrometry (LC-MS/MS) for mitochondrial proteomics and lipidomics.
Service Scope
Protheragen delivers a specialized suite of preclinical mitochondrial assays engineered specifically to address the technical challenges of lipid-dense metabolic tissues.
Extracting functional mitochondria from obese tissue samples poses unique technical challenges due to heavy lipid interference and cellular fragility. Protheragen utilizes optimized, tissue-specific isolation buffers and gentle homogenization techniques calibrated specifically for white adipose tissue (WAT), brown adipose tissue (BAT), liver, and skeletal muscle from preclinical animal models. Our methods preserve organelle outer membrane integrity and maintain native enzymatic activity for downstream biochemical applications.
Downstream molecular analyses require highly purified mitochondrial fractions free from endoplasmic reticulum (ER), lysosomal, and cytosolic contamination. Using customized density gradient ultracentrifugation (Percoll/Sucrose matrices), we isolate ultra-pure mitochondrial populations from high-fat diet (HFD) model tissues. This ultra-purification ensures accurate attribution of proteomic and metabolomic signatures specifically to the organelle.
Mitochondrial dynamics—comprising fusion, fission, and cristae remodeling—are severely dysregulated in obesity. Our structural analysis service utilizes high-resolution transmission electron microscopy (TEM) and quantitative image analysis software to measure cristae density, organelle surface area, volume density, matrix swelling, and network elongation. These parameters provide quantitative structural markers for evaluating therapeutic drug candidates.
Evaluate metabolic flux and respiratory capacity across isolated mitochondria or primary preclinical cell cultures. Our platform measures real-time basal respiration, ATP-linked respiration, proton leak, maximum respiratory capacity, and non-mitochondrial oxygen consumption. By selectively targeting individual ETC complexes (complex I–V), we pinpoint exact respiratory chain deficiencies induced by lipid toxicity.
Nutrient excess often drives mitochondrial oxidative stress, lipid peroxidation, calcium overload, and permeability transition pore (mPTP) opening. This service evaluates mitochondrial ROS generation, antioxidant enzyme depletion, mitochondrial DNA lesion frequency, and the release of apoptosis-inducing factors. These assays reveal the molecular cascades underlying lipotoxicity and organelle degradation in preclinical models.
Mitochondrial DNA is particularly susceptible to oxidative damage due to its proximity to the ETC and lack of protective histones. We offer specialized deep NGS for the mitochondrial genome, providing high-sensitivity identification of mtDNA point mutations, deletions, structural variants, and absolute copy number depletion relative to nuclear DNA in obese preclinical tissue models.
Map dynamic changes in the mitochondrial proteome under metabolic stress. Utilizing high-resolution LC-MS/MS coupled with isobaric labeling or label-free quantification, our proteomics platform profiles mitochondrial protein expression, post-translational modifications (such as reversible oxidation, acetylation, and phosphorylation), and transport complexes involved in metabolic regulation.
Uncover altered intramitochondrial metabolic intermediate profiles. Our targeted and untargeted metabolomics service quantifies key intermediates of the tricarboxylic acid (TCA) cycle, acylcarnitines, amino acids, and specialized membrane lipids (such as cardiolipin species). This metabolic profiling reveals specific enzymatic bottlenecks and flux alterations caused by obesity.
