The purpleback flying squid () is a pelagic squid with tremendous potential for commercial exploitation. comprises two forms in the South China Sea, medium-sized form and dwarf form. In this study, we described the complete mitochondrial genome of medium-sized form of The genome is 20,309 bp in length, encoding the standard set of 13 protein-coding genes, 20 tRNA genes, and two rRNA genes, with circular organization. The overall base composition of the whole mitochondrial genome was A (35.86%), T (33.36%), G (11.63%), and C (19.15%) with an AT bias of 69.22%. The longest protein-coding gene of these species was , whereas the shortest .

Aim: Mitochondria play key roles in neuronal activity, particularly in modulating agouti-related protein (AgRP) and proopiomelanocortin (POMC) neurons in the arcuate nucleus of the hypothalamus (ARC), which regulates food intake. FAM163A, a newly identified protein, is suggested to be part of the mitochondrial proteome, though its functions remain largely unknown. This study aimed to investigate the effects of Fam163a knockdown and mitochondrial dysfunction on food intake, AgRP neuron activity, and mitochondrial function in the hypothalamus.

(Caudata, Hynobiidae) is a recently described species, identified in 2022, and is thus not widely known. In this study, we sequenced and annotated the complete mitogenome of . The resulting mitochondrial genome is 16,406 bp in length and comprises 13 protein-coding genes (PCGs), two ribosomal RNA genes (rRNA), 22 transfer RNA genes, and a non-coding region.

Reactive oxygen species (ROS) generate DNA lesions that alter genome integrity. Among those DNA lesions, 7,8-dihydro-8-oxo-2'-deoxyguanosine (8-oxodG) is particularly mutagenic. 8-oxodG efficiently incorporates deoxycytidine monophosphate (dCMP) and deoxyadenosine monophosphate (dAMP) via base pairing mediated by its anti and syn conformations, respectively.

Background: Changing ocean temperatures are already causing declines in populations of marine organisms. Predicting the capacity of organisms to adjust to the pressures posed by climate change is a topic of much current research effort, particularly for species we farm or harvest. To explore one measure of phenotypic plasticity, the physiological compensations in response to heat stress as might be experienced in a marine heatwave, we exposed Yellowtail Kingfish (Seriola lalandi) to sublethal heat stress, and used the transcriptome in gill and muscle, benchmarked against heat shock proteins and oxidative stress indicators, to characterise the acute heat stress response (6 h after the initiation of stress), and the physiological compensation to that response (24 and 72 h after the initiation of stress).
