Mitochondrial dysfunction is associated with a spectrum of human disorders, ranging from rare, inborn errors metabolism to common, age-associated diseases such as neurodegeneration. How these lesions give rise diverse pathology not well understood, partly because their proximal consequences have been well-studied in mammalian cells. Here we provide two lines evidence that mitochondrial respiratory chain leads alterations one-carbon pathways. First, using hypothesis-generating metabolic,...

VERVE-101 is an investigational in vivo CRISPR base-editing medicine designed to alter a single DNA base the PCSK9 gene, permanently turn off hepatic protein production, and thereby durably lower low-density lipoprotein cholesterol. We test efficacy, durability, tolerability, potential for germline editing of studies nonhuman primates murine F1 progeny study.Cynomolgus monkeys were given intravenous infusion vehicle control (n=10) or at dose 0.75 mg/kg (n=4) 1.5 (n=22) with subsequent...

Despite the role of aerobic glycolysis in cancer, recent studies highlight importance mitochondria and biosynthetic pathways as well. PPARγ coactivator 1α (PGC1α) is a key transcriptional regulator several metabolic including oxidative metabolism lipogenesis. Initial suggested that PGC1α expression reduced tumors compared with adjacent normal tissue. Paradoxically, other show associated cancer cell proliferation. Therefore, especially carcinogenesis unclear. Using Pgc1α(-/-) Pgc1α(+/+) mice,...

Tau hyperphosphorylation is a central event in the development of Alzheimer's Disease (AD). Protein phosphatase 2A (PP2A) heterotrimer formation necessary for efficient dephosphorylation tau protein. S ‐Adenosylmethionine‐dependent carboxyl methylation essential assembly PP2A heterotrimers. Epidemiological evidence indicates that elevated plasma homocysteine an independent risk factor AD. Homocysteine key intermediate methyl cycle and results global decrease cellular methylation. We propose...

Current therapy for lung cancer involves multimodality therapies. However, many patients are either refractory to or develop drug resistance. KRAS and epidermal growth factor receptor (EGFR) mutations represent some of the most common in cancer, studies have shown importance these both carcinogenesis chemoresistance. Genetically engineered murine models mutant EGFR been developed that more accurately recapitulate human cancer. Recently, using cell-based experiments, we showed platinum-based...

Mitochondrial diseases comprise a diverse set of clinical disorders that affect multiple organ systems with varying severity and age onset. Due to their genetic heterogeneity, these are difficult diagnose. We have developed targeted exome sequencing approach improve our ability properly diagnose mitochondrial apply it here an individual patient. Our method targets DNA (mtDNA) the exons 1,600 nuclear genes involved in biology or Mendelian multi-system phenotypes, thereby allowing for...

CHADN eliminated norepinephrine content liver and partially decreased it pancreas upper gut. We oral tolerance at baseline after 4 weeks high-fat high-fructose (HFHF) feeding. Dogs were then randomized to sham surgery (SHAM) (n = 9) or 11) retested 2.5 3.5 later while still on HFHF diet. improved by ∼60% part because enhanced insulin secretion, as indicated...

Deficiency of mitochondrial complex I is encountered in both rare and common diseases, but we have limited therapeutic options to treat this lesion the oxidative phosphorylation system (OXPHOS). Idebenone menadione are redox-active molecules capable rescuing OXPHOS activity by engaging I-independent pathways entry, often referred as "complex bypass." In present study, created a cellular model deficiency using CRISPR genome editing knock out Ndufa9 mouse myoblasts, utilized cell line develop...

Introduction: Maintaining LDL-C at goal levels is critical in populations high risk for cardiovascular events, including people with heterozygous familial hypercholesterolemia (HeFH) and/or premature coronary artery disease (CAD). Despite multiple approved lowering therapies these populations, most patients are not guideline-directed treatment goal. In vivo base editing to inactivate hepatic PCSK9 has the potential provide lifelong after a single course of treatment. Success approach...
