Cytosolic DNA composition is determined by genomic instability mechanism and regulates dendritic cell-mediated anti-tumor immunity by Shayla R. Mosley, Angie Chen, David N.W. Doell, Siwon Choi, Courtney Mowat, Felix Meier-Stephenson, Vanessa Meier-Stephenson, Kristi Baker

“…DNA-damaging therapies also modulate cyDNA stimulation capacity, with radiation inducing larger cyDNA sizes and increased mitochondrial DNA content. Identifying highly stimulatory endogenous cyDNAs such as those in MSI CRCs will allow for optimized development of DNA-based STING agonist therapies to improve the responses of CIN CRCs with CIN to immunotherapies.…”

Cytotoxic mechanisms of pemetrexed and HDAC inhibition in non-small cell lung cancer cells involving ribonucleotides in DNA by Tobias Solli Iveland, Lars Hagen, Mirta Mittelstedt Leal de Sousa, Nina Beate Liabakk, Per Arne Aas, Animesh Sharma, Bodil Kavli, Geir Slupphaug

“…Contrary to the conventional model of antifolate toxicity, which implicates futile cycles of uracil incorporation and excision in DNA, we propose that ribonucleotide incorporation in nuclear and mitochondrial DNA significantly contributes to the cytotoxicity of antifolates like pemetrexed, and likely also of fluorinated pyrimidine analogs. …”

Enhanced Tolerance to Antifungals as a General Feature of Rho⁻ Mutants in Yeast Species: Implications to Positive Selection of Respiratory Deficiency by Zachary Johnson, Farhan Nadim, Mikhajlo K. Zubko

“…Although the mitochondrial genome is an attribute of all eukaryotes, some yeast species (called petite-positive) can replicate without mitochondrial DNA (mtDNA). Strains without mtDNA (known as rho⁻ mutants or petite mutants) are respiration-deficient and require fermentable carbon sources (such as glucose) for their metabolism. …”

Poyarkov, Spartak N. Litvinchuk, Tomasz Suchan, Mathieu Denoël, Daniel Jablonski

“…As it reached the Dinarides during the Late Pleistocene, B. v. variegata potentially hybridized with B. v. scabra and captured its mitochondrial DNA, which resulted in a massive cyto-nuclear discordance across all northwestern European populations. …”

High-coverage whole-genome sequencing of a Jakun individual from the “Orang Asli” Proto-Malay subtribe from Peninsular Malaysia by Wai-Sum Yap, Alvin Cengnata, Woei-Yuh Saw, Thuhairah Abdul Rahman, Yik-Ying Teo, Renee Lay-Hong Lim, Boon-Peng Hoh

“…The ADMIXTURE analysis further revealed potential admixture from the EA and North Borneo populations, as corroborated by the results from the F3, F4, and TreeMix analyses. Mitochondrial DNA analysis revealed that the Jakun genome carried the N21a haplogroup (estimated to have occurred ~19 kya), which is commonly found among Malays from Malaysia and Indonesia. …”

Carvacrol acetate activated Nrf2 modulates mitophagy for the treatment of neurocyte oxidative stress induced by chlorpyrifos by Hong-Ling Zhou, Bei-Bei Wang, Xu-Li Fan, Xiao-Min Zhang, Ying Song

“…It decreased both intra- and extracellular levels of reactive oxygen species (ROS), malondialdehyde (MDA), superoxide dismutase (SOD), while markedly elevating mitochondrial DNA (mtDNA) copy number. Moreover, PC12 cells treated with Nrf2 inhibitors failed to exhibit any improvement in survival rate when treated with CAA after a toxic insult. …”

“…The first estimates of the genetic diversity and differentiation have been obtained from five of them: 1) Azov & Black Sea, 2) Caspian, 3) Volga & Ural, 4) South Siberian and 5) Eastern Asian sampled across the total breeding range in Russia using data from 10 microsatellite loci and the 1 003-bp control region of mitochondrial DNA. In total, the Demoiselle crane demonstrates high level of observed (HO = 0.638 ± 0.032) and expected (HE = 0.657 ± 0.023) hete-rozygosity and haplotype diversity (h = 0.960). …”

Resveratrol enhances post-injury muscle regeneration by regulating antioxidant and mitochondrial biogenesis by Xiaoli Qin, Wenjing Niu, Kai Zhao, Yawen Luo, Wenfang Wang, Yang He, Fuyu Yang, Binghai Cao, Min Du, Huawei Su

“…Transcriptomic analysis identified enriched pathways related to muscle regeneration and mitochondrial biogenesis, with increased expression of mitochondrial transcription factors and higher mitochondrial DNA content in RES-treated mice. Furthermore, RES enhanced antioxidant capacity via the Kelch-like ECH-associated protein 1 (KEAP-1)/nuclear factor erythroid 2-related factor 2 (NRF2)/heme oxygenase-1 (HO-1) signaling pathway, as indicated by elevated activities of total antioxidant capacity, Glutathione peroxidase (GSH-PX), and superoxidase dismutase (SOD). …”
