Characterization of the Mitochondrial Phenotype Associated with Primary Biliary Cholangitis
DownloadSpring 2017
Primary Biliary Cholangitis (PBC) is a chronic liver disease characterized by the immune-mediated destruction of intra-hepatic bile ducts. The autoimmune nature of PBC involves humoral and cell-mediated responses that target endogenous mitochondrial proteins. It is thought that the breakdown of...

Chronic Fatigue Mechanisms in Autoimmune Diseases: Lessons from Primary Biliary Cholangitis and Systemic Sclerosis
DownloadFall 2023
Systemic sclerosis (SSc) is an autoimmune disease affecting the body's connective tissues, resulting in progressive fibrosis and vasculopathy. In some cases, individuals with SSc may also develop primary biliary cholangitis (PBC), another autoimmune disease characterized by damage to their...

Renal cell carcinoma comprises approximately 2-3% of all malignancies, with the majority, approximately 70%, being clear cell renal cell carcinoma (ccRCC). ccRCC features many cancer hallmarks such as suppressed mitochondrial glucose oxidation, apoptosis-resistance, angiogenesis, immune evasion,...

Mitochondria generate reactive oxygen species (mROS) and metabolic substrates like alpha-ketogluterate (αKG), in proportion to oxygen, which target extra-mitochondrial effectors to coordinate a cellular response. For example, acute hypoxia decreases mROS, resulting in pulmonary artery smooth...

Understanding Heart Failure in Patients with Dilated Cardiomyopathy: A Direct Tissue Analysis from Explanted Human Hearts
DownloadFall 2022
Background Chronic heart failure (HF) remains a rising global epidemic that affects both adults and children population. The causes of HF are heterogeneous, and syndromes are often complicated by concomitant disorders such as iron deficiency (ID) and diabetes. Comorbidities not only complicate...

Unveiling the pathway for the nuclear translocation of the large mitochondrial enzyme Pyruvate Dehydrogenase Complex (PDC)
DownloadSpring 2021
Pyruvate dehydrogenase complex (PDC) is a mitochondrial enzyme that links glycolysis to oxidative phosphorylation by decarboxylating glucose-derived pyruvate to produce acetyl-CoA that is used in the Krebs cycle. PDC was initially thought to reside only in the mitochondrial matrix but we recently...
