The complete mitochondrial genome (mitogenome) of Callerebia suroia (Lepidoptera: Nymphalidae: Satyrinae) was determined and analyzed in this paper. The circular genome is 15,208 bp long, including 37 typical mitochondrial genes and one non-coding AT-rich region. All protein-coding genes (PCGs) started with ATN, except for COI gene with CGA(R), which is often found in other butterflies; nine PCGs harbor the typical stop codon TAA, whereas COI, COII, ND5 and ND4 end with a single T. All tRNA genes display typical secondary clover-leaf structures, except for tRNA(Ser)(AGN), whose dihydrouridine (DHU) arm is replaced by a simple loop. The lrRNA and srRNA genes are 1,347 bp and 753 bp in length, with their AT contents of 84.4% and 85.4%, respectively. The 417 bp AT-rich region contains non repetitive sequences, but harbor several features common to the lepidopterans, including the motif ATAGA followed by a 19-bp poly-T stretch and a microsatellite-like (TA)8 element preceded by the ATTTA motif.

Introduction: Mitochondria are essential organelles that provide energy for plants. They are semi-autonomous, maternally inherited, and closely linked to cytoplasmic male sterility (CMS) in plants. , a widely used medicinal plant from the Caprifoliaceae family, is rich in chlorogenic acid (CGA) and its analogues, which are known for their antiviral and anticancer properties.

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.
