We assembled the mitogenome of the Bythograeid crab , using long-range amplification of the mitochondrial genome. The mitogenome is 15,521 base pair long (33.8% A, 21.7% C, 10.5% G, 34% T) with 13 protein-coding genes, 2 ribosomal RNA genes, 22 transfer RNAs, and a 624 bp AT-rich region. The gene arrangement is similar to other Brachyuran species. A whole genome shotgun sequencing approach revealed the presence of mitochondrial pseudogenes in the nuclear genome. This fifth mitogenome for a species of Bythograeidae should help resolve the puzzling question of the evolutionary origin of a family limited to deep-sea hydrothermal vents.

DNA can fold into noncanonical left-handed Z-DNA conformation beyond the right-handed B-DNA. While its crystal structure was discovered nearly four decades ago, it was predominantly considered a structural curiosity. Recent evidence suggests that Z-DNA formation occurs in nuclear and mitochondrial DNA (mtDNA), with significant biological implications.

We have described a novel mitochondrial disorder caused by biallelic pathogenic variants in the methionyl-tRNA synthetase 2 gene (MARS2), now termed Combined oxidative phosphorylation deficiency 25 (COXPD25). This study focuses on the generation and characterization of induced pluripotent stem cells (iPSCs) from fibroblasts of a patient with COXPD25. The resulting iPSC line ISMMSi060-A, carries the compound heterozygous variants c.

Glucose-6-phosphate dehydrogenase (G6PD) is the rate-limiting enzyme in the pentose phosphate pathway (PPP) in glycolysis. Glucose metabolism is closely implicated in the regulation of mitophagy, a selective form of autophagy for the degradation of damaged mitochondria. The PPP and its key enzymes such as G6PD possess important metabolic functions, including biosynthesis and maintenance of intracellular redox balance, while their implication in mitophagy is largely unknown.
