DOI: 10.1002/advs.202410439

Abstract: Skeletal muscle atrophy (sarcopenia) is a serious complication of liver cirrhosis, and chronic muscle inflammation plays a pivotal role in its pathologenesis. However, the detailed mechanism through which injured liver tissues mediate skeletal muscle inflammatory… read more here.

DOI: 10.1002/advs.202414260

Abstract: Lipid metabolism disorders in both neurons and glial cells have been found in neurodegenerative (ND) patients and animal models. However, the pathological connection between lipid droplets and NDs remains poorly understood. The recent work has… read more here.

DOI: 10.1002/em.22319

Abstract: Maintenance of the mitochondrial genome is essential for proper cellular function. For this purpose, mitochondrial DNA (mtDNA) needs to be faithfully replicated, transcribed, translated, and repaired in the face of constant onslaught from endogenous and… read more here.

DOI: 10.1002/em.22449

Abstract: Digital PCR (dPCR) has been adapted to quantify the proportion of mitochondrial DNA (mtDNA) molecules without and with double‐strand DNA breaks (DSBs). This is based on a break‐apart approach of two differentially labeled target sequences… read more here.

DOI: 10.1002/mdc3.12962

Abstract: I read with interest the article by Pauly and colleagues about a family in which the father carried the variants c.844T>G in POLG1 and c.937G>A in CLCN1. The POLG1 variant manifested with ptosis, ophthalmoparesis, parkinsonism,… read more here.

DOI: 10.1002/mgg3.2059

Abstract: Kearns‐Sayre syndrome (KSS) is a rare multisystem mitochondrial disorder characterized by onset before 20 years of age and a typical clinical triad: progressive external ophthalmoplegia, pigmentary retinopathy and cardiac conduction anomalies. In most cases KSS is… read more here.

DOI: 10.1002/mrd.23655

Abstract: Mitochondrial DNA (mtDNA) plays a crucial role in the development of a competent oocyte. Indeed, mtDNA alterations may predispose to chromosome nondisjunction, resulting in infertility due to a reduced vitality and quality of oocytes and… read more here.

DOI: 10.1007/s00216-017-0217-x

Abstract: AbstractTo establish a method for accurate quantitation of circulating cell-free mitochondrial DNA (ccf-mtDNA) in plasma by droplet digital PCR (ddPCR), we designed a ddPCR method to determine the copy number of ccf-mtDNA by amplifying mitochondrial… read more here.

DOI: 10.1007/s00294-017-0717-4

Abstract: Mitochondria are dynamic organelles that fuse and divide. These changes alter the number and distribution of mitochondrial structures throughout the cell in response to developmental and metabolic cues. We have demonstrated that mitochondrial fission is… read more here.

DOI: 10.1007/s00415-017-8409-z

Abstract: The sporadic occurrence of a mitochondrial disease, including chronic progressive external ophthalmoplegia (CPEO), Kearns–Sayre syndrome (KSS, MIM 530000), and in infancy, Pearson syndrome (MIM 557000) may suggest the presence of a single, sporadic mitochondrial DNA… read more here.
