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. …”

Natural repeated backcrosses lead to triploidy and tetraploidy in parthenogenetic butterfly lizards (Leiolepis: Agamidae) by Eduard Galoyan, Roman Nazarov, Marie Altmanová, Sergey Matveevsky, Ivan Kropachev, Dmitrij Dedukh, Eugene Iryshkov, Mark Pankin, Natalia Sopilko, Oleg Nikolaev, Nikolai Orlov, Marine Arakelyan, Jiří Klíma, Evgeniya Solovyeva, Tao Nguyen, Lukáš Kratochvíl

“…Contrary to previous proposals, we document that parthenogenetic L. guentherpetersi has mitochondrial DNA and two haploid sets from L. guttata and one from L. reevesii, suggesting that it is the result of a backcross of a parthenogenetic L. guttata × L. reevesii hybrid with a L. guttata male increasing ploidy from 2n to 3n. …”

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. …”

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 Demoiselle crane (Anthropoides virgo) population genetic structure in Russia by E. A. Mudrik, Е. I. Ilyashenko, О. А. Goroshko, T. A. Kashentseva, М. V. Korepov, I. A. Sikorskiy, G. S. Dzhamirzoev, V. Yu. Ilyashenko, D. V. Politov

“…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). …”

Genetic history of the Koryaks and Evens of the Magadan region based on Y chromosome polymorphism data by B. A. Malyarchuk, M. V. Derenko

“…The genetic contribution of the European males’ Y chromosome significantly prevails over that of maternally inherited mitochondrial DNA. The study of the Y chromosome haplogroup diversity has shown that only relatively young phylogenetic branches have been preserved in the Koryak gene pool. …”

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). …”

“…We further found that NMOSD provoked the translocation of TDP43 to mitochondria and the release of mitochondrial DNA (mtDNA) into the cytoplasm. NMOSD caused activation of mtDNA/cyclic GMP-AMP synthase (cGAS) / stimulator of interferon genes (STING) pathway and A1-type inflammatory activation in astrocytes. …”
