Doxorubicin (DOX) is a highly effective antineoplastic agent used in cancer treatment. Unfortunately, clinical use of DOX is limited due to the development of dose-dependent toxicity to cardiac and respiratory (i.e., diaphragm) muscles. After adminis…
BACKGROUND: Dilated cardiomyopathy with ataxia syndrome (DCMA) is an understudied autosomal recessive disease caused by loss-of-function mutations in the poorly characterized gene DNAJC19. Clinically, DCMA is commonly associated with heart failure an…
This article highlights preclinical and clinical studies in the field of wasting disorders that were presented at the 12th Cachexia Conference held in Berlin, Germany, in December 2019. Herein, we summarize the biological and clinical significance of…
BACKGROUND: Elamipretide, a novel mitochondrial modulating agent, improves myocardial energetics; however, it is unknown whether this mechanistic benefit translates into improved cardiac structure and function in heart failure (HF) with reduced eject…
BACKGROUND: This study aims to evaluate the effect of subcutaneous (SC) elamipretide dosing on exercise performance using the 6 min walk test (6MWT), patient-reported outcomes measuring fatigue, functional assessments, and safety to guide the develop…
Arsenic exposure impairs muscle metabolism, maintenance, progenitor cell differentiation, and regeneration following acute injury. Low to moderate arsenic exposures target muscle fiber and progenitor cell mitochondria to epigenetically decrease muscl…
Renal activation of the complement system has been described in patients with diabetic nephropathy (DN), although its pathological relevance is still ill-defined. Here, we studied whether glomerular C3a, generated by uncontrolled complement activatio…
As a technique widely used in assisted reproduction, human spermatozoa cryopreservation makes it possible to conserve functional sperm for a long time, but the impact of cryodamage on sperm during the process could not be ignored. The objective of th…
Mitochondrial dysfunction underlies many heritable diseases, acquired pathologies, and aging-related declines in health. Szeto-Schiller (SS) peptides comprise a class of amphipathic tetrapeptides that are efficacious toward a wide array of mitochondr…
Exposure to chronic hyperglycemia because of diabetes mellitus can lead to development and progression of diabetic kidney disease (DKD). We recently reported that reduced superoxide production is associated with mitochondrial dysfunction in the kidne…
This study investigates the inhibitory effect and potential mechanism of ligustrazine combined with paeonol on hepatic fibrosis, as to provide a new therapeutic strategy for clinical hepatic fibrosis. The degree of liver injury collagen deposition an…
The loss of muscle mass and function with age, termed sarcopenia, is an inevitable process, which has a significant impact on quality of life. During ageing we observe a progressive loss of total muscle fibres and a reduction in cross-sectional area…
Leber's hereditary optic neuropathy (LHON) is a rare, maternally-inherited optic neuropathy caused by mitochondrial DNA point mutations and which can cause blindness. Currently, Raxone (idebenone) is the only available medicinal product authorised to…
Mitochondrial dysfunction underlies the etiology of a broad spectrum of diseases including heart disease, cancer, neurodegenerative diseases, and the general aging process. Therapeutics that restore healthy mitochondrial function hold promise for tre…
Compromise of skeletal muscle metabolism and composition may underlie the etiology of cardiovascular and metabolic disease risk from environmental arsenic exposures. We reported that arsenic impairs muscle maintenance and regeneration by inducing mal…
Diastolic dysfunction is a prominent feature of cardiac aging in both mice and humans. We show here that 8-week treatment of old mice with the mitochondrial targeted peptide SS-31 (elamipretide) can substantially reverse this deficit. SS-31 normalize…
Mitochondrial dysfunction contributes to cardiac pathologies. Barriers to new therapies include an incomplete understanding of underlying molecular culprits and a lack of effective mitochondria-targeted medicines. Here, we test the hypothesis that th…
OBJECTIVE: This study aimed to assess the effect and mechanism of SS31 on cisplatin-induced acute kidney injury (CP-AKI) both in vivo and in vitro. METHOD: Male mices and HK-2 cells were treated using cisplatin to establish models of CP-AKI. 32 C57BL…
After ischemic stroke, oxygen and nutrition depletion induce mitochondrial dysfunction, which aggravates brain injury. Bendavia, a mitochondria-targeted tetra-peptide, has anti-oxidative and anti-inflammatory activities. We previously reported that b…
Traumatic optic neuropathy (TON) can occur following blunt trauma to the orbit and can lead to permanent vision loss. In this study, we investigated the effectiveness of elamipretide (MTP-131), a small mitochondrially-targeted tetrapeptide, in conjun…
