Although, PARP2 plays role in DNA repair, it has regulatory roles in mitochondrial and lipid metabolism, it has pivotal role in bringing about the adverse effects of pharmacological PARP inhibitors. Previously, we showed that the ablation of PARP2 induces oxidative stress and, consequently, mitochondrial fragmentation. In attempt to identify the source of the reactive species we assessed the possible role of a central regulator of cellular antioxidant defense, nuclear factor erythroid 2-related factor 2 (NRF2). The silencing of PARP2 did not alter either the mRNA or the protein expression of NRF2, but changed its subcellular localization, decreasing the proportion of nuclear, active fraction of NRF2. Pharmacological inhibition of PARP2 partially restored the normal localization pattern of NRF2 and in line with that, we showed that NRF2 is PARylated that is absent in the cells in which PARP2 was silenced. Apparently, the PARylation of NRF2 by PARP2 has pivotal role in regulating the subcellular (nuclear) localization of NRF2. The silencing of PARP2 rearranged the expression of genes encoding proteins with antioxidant function, among these a subset of NRF2-dependent genes.}, year = {2023}, eissn = {2045-2322}, orcid-numbers = {Bálint, Bálint László/0000-0002-6163-7190} } @article{MTMT:32058440, title = {Silencing of Poly(ADP-Ribose) Polymerase-2 Induces Mitochondrial Reactive Species Production and Mitochondrial Fragmentation}, url = {https://m2.mtmt.hu/api/publication/32058440}, author = {Jankó, Laura and Kovács, Tünde and Laczik, Miklós and Sári, Zsanett Mercédesz and Ujlaki, Gyula and Kis, Nikoletta Gréta and Horváth, Ibolya and Antal, Miklós and Vigh, László and Bálint, Bálint László and Uray (Davis), Karen L. and Bay, Péter}, doi = {10.3390/cells10061387}, journal-iso = {CELLS-BASEL}, journal = {CELLS}, volume = {10}, unique-id = {32058440}, year = {2021}, eissn = {2073-4409}, orcid-numbers = {Bálint, Bálint László/0000-0002-6163-7190;

We show that the ablation of PARP2 induced characteristic changes in the lipidome. The silencing of PARP2 induced the expression of sterol regulatory element-binding protein-1 and -2 and initiated de novo cholesterol biosynthesis in skeletal muscle. Increased muscular cholesterol was shunted to muscular biosynthesis of dihydrotestosterone, an anabolic steroid. Thus, skeletal muscle fibers in PARP2(-/-) mice were stronger compared to those of their wild-type littermates. In addition, we detected changes in the dynamics of the cell membrane, suggesting that lipidome changes also affect the biophysical characteristics of the cell membrane. In in silico and wet chemistry studies, we identified lipid species that can decrease the expression of PARP2 and potentially phenocopy the genetic abruption of PARP2, including artificial steroids. In view of these observations, we propose a new role for PARP2 as a lipid-modulated regulator of lipid metabolism.}, year = {2018}, eissn = {1879-2618}, pages = {1399-1412}, orcid-numbers = {Bojcsuk, Dóra/0000-0001-5091-7237; Bhattoa Harjit, Pál/0000-0002-4909-0065; Bálint, Bálint László/0000-0002-6163-7190} }
