The Common Rock Rat is an abundant small- to medium-sized Murid rodent that is endemic to Australia. It is a nocturnal mammal with a mostly herbivorous diet. This species is native to the wet/dry tropics of Northern Australia and can be identified from other rock rats on the basis of its small size and its tail length (which is at least equivalent to its head-body length). Here, we describe the complete mitochondrial genome of and compare it to other Rodentia. The circular mitogenome was 16,261 bp and contained 13 protein-coding genes, two rRNA genes, 22 tRNAs and a control region (D-loop) of 859 bp. Phylogenetic analysis of selected, published sequenced mitogenomes reveal it is most closely related to the Lakeland Downs mouse in the order Rodentia.

Under pathological conditions, astrocytes can transfer mitochondria to neurons, where they exert neuroprotective effects. In this context, we present a protocol for capturing astrocytic mitochondria in neurons of adult mice using a two-photon microscope. We describe an approach for constructing a mouse model with combined labeling of astrocytic mitochondria and neurons.

Telomerase, constituted by the dynamic duo of telomerase reverse transcriptase (TERT), the catalytic entity, and an integral RNA component (TERC), is predominantly suppressed in differentiated human cells due to postnatal transcriptional repression of the TERT gene. Dysregulation of telomerase significantly contributes to cancer development via telomere-dependent and independent mechanisms. Telomerase activity is often elevated in advanced cancers, with TERT reactivation and upregulation of TERC observed in early tumorigenesis.

Kinetoplastids display a single, large mitochondrion per cell, with their mitochondrial DNA referred to as the kinetoplast. This kinetoplast is a network of concatenated circular molecules comprising a maxicircle (20-64 kb) and up to thousands of minicircles varying in size depending on the species (0.5-10 kb).

(1) Background: is a major parasite of large porpoises and whales and has been classified in the Habronematoidea family. However, there has been a great controversy regarding its classification. Mitochondria have an important function in revealing taxonomic and evolutionary history.

, a marine benthic diatom, holds promise for human nutrition and health as well as for aquaculture applications. However, the scarcity of organelle genome data within the Navicula clade has impeded a comprehensive understanding and utilization of this group. Our research presents a pioneering exploration into the complete mitochondrial and chloroplast genome sequences of CACC 0356, shedding light on its phylogeny and evolutionary history.
