Here, we investigated the role of cyclophilin D (CypD)-dependent mitochondrial permeability transition (mPT) in the immunosuppressive phase of LPS-induced endotoxic shock. The liver plays an important role in immunity and organ dysfunction; therefore, we used liver RNA sequencing (RNAseq) data, Ingenuity® Pathway Analysis (IPA ® ) to investigate the complex role of mPT formation in inflammatory reprogramming and disease progression. LPS induced significant changes in the expression of 2844 genes, affecting 179 pathways related to mitochondrial dysfunction, defective oxidative phosphorylation, nitric oxide (NO) and reactive oxygen species (ROS) accumulation, nuclear factor, erythroid 2 like 2 (Nrf2), Toll-like receptors (TLRs), and tumor necrosis factor α receptor (TNFR)-mediated processes in wild-type mice. The disruption of CypD reduced LPS-induced alterations in gene expression and pathways involving TNFRs and TLRs, in addition to improving survival and attenuating oxidative liver damage and the related NO- and ROS-producing pathways. CypD deficiency diminished the suppressive effect of LPS on mitochondrial function, nuclear- and mitochondrial-encoded genes, and mitochondrial DNA (mtDNA) quantity, which could be critical in improving survival. Our data propose that CypD-dependent mPT is an amplifier in inflammatory reprogramming and promotes disease progression. The mortality in human sepsis and shock is associated with mitochondrial dysfunction. Prevention of mPT by CypD disruption reduces inflammatory reprogramming, mitochondrial dysfunction, and lethality; therefore, CypD can be a novel drug target in endotoxic shock and related inflammatory diseases.}, keywords = {Inflammation; LIVER; ENDOTOXIN; ANTIOXIDANT; Mitochondria; Gene Expression; Toll-like receptor; Reprogramming; cyclophilin D; Oxidative stress}, year = {2021}, eissn = {2211-5463}, pages = {684-704}, orcid-numbers = {Tretter, László/0000-0001-5638-2886; Gallyas, Ferenc/0000-0002-1906-4333} } @misc{MTMT:33094592, title = {Amiodarone’s major metabolite, desethylamiodarone inhibits proliferation and in vivo metastasizing property of B16-F10 melanoma cells}, url = {https://m2.mtmt.hu/api/publication/33094592}, author = {Bognár, Zita and Cseh, Anna Mária and Fekete, Katalin and Antus, Csenge Petra and Bognár, Rita and Tapodi, Antal and Ramadan, Fadi and Sümegi, Balázs and Gallyas, Ferenc}, unique-id = {33094592}, year = {2020}, orcid-numbers = {Gallyas, Ferenc/0000-0002-1906-4333} } @article{MTMT:31659630, title = {Resveratrol Improves Heart Function by Moderating Inflammatory Processes in Patients with Systolic Heart Failure}, url = {https://m2.mtmt.hu/api/publication/31659630}, author = {Gál, Roland and Deres, László and Horváth, Orsolya and Erős, Krisztián and Sándor, Barbara and Urbán, Péter and Soós, Szilvia and Márton, Zsolt and Sümegi, Balázs and Tóth, Kálmán and Habon, Tamás and Halmosi, Róbert}, doi = {10.3390/antiox9111108}, journal-iso = {ANTIOXIDANTS-BASEL}, journal = {ANTIOXIDANTS}, volume = {9}, unique-id = {31659630}, year = {2020}, eissn = {2076-3921}, orcid-numbers = {Sándor, Barbara/0000-0002-7028-4227; Habon, Tamás/0000-0002-4816-857X} } @article{MTMT:31617910, title = {Amiodarone's major metabolite, desethylamiodarone inhibits proliferation of B16-F10 melanoma cells and limits lung metastasis formation in an in vivo experimental model}, url = {https://m2.mtmt.hu/api/publication/31617910}, author = {Bognár, Zita and Cseh, Anna Mária and Fekete, Katalin and Antus, Csenge Petra and Bognár, Rita and Tapodi, Antal and Ramadan, Fadi and Sümegi, Balázs and Gallyas, Ferenc}, doi = {10.1371/journal.pone.0239088}, journal-iso = {PLOS ONE}, journal = {PLOS ONE}, volume = {15}, unique-id = {31617910}, issn = {1932-6203}, abstract = {Previously, we demonstrated the in vitro anti-tumor effects of desethylamiodarone (DEA) in bladder and cervix cancer cell lines. In the present study, we intended to establish its potentiality in B16-F10 metastatic melanoma cells in vitro and in vivo. We assessed cell proliferation, apoptosis and cell cycle by using sulforhodamine B assay, Muse™ Annexin V & Dead Cell and Muse® Cell Cycle assays, respectively. We determined colony formation after crystal violet staining. For studying mechanistic aspects, immunoblotting analysis was performed. We used a C57BL/6 experimental lung metastasis model for demonstrating in vivo anti-metastatic potential of DEA. DEA inhibited in vitro proliferation and colony formation, and in vivo lung metastasizing properties of B16-F10 cells. It arrested the cells in G0/G1 phase of their cycle likely via p21 in a p53-dependent fashion, and induced caspase mediated apoptosis likely via inversely regulating Bcl-2 and Bax levels, and reducing Akt and ERK1/2 activation. In this study, we provided in vitro and in vivo experimental evidences for DEA's potentiality in the therapy of metastatic melanomas. Since DEA is the major metabolite of amiodarone, a worldwide used antiarrhythmic drug, safety concerns could be resolved more easily for it than for a novel pharmacological agent.}, year = {2020}, eissn = {1932-6203}, orcid-numbers = {Gallyas, Ferenc/0000-0002-1906-4333} } @article{MTMT:31288947, title = {Mitochondrial Protection by PARP Inhibition}, url = {https://m2.mtmt.hu/api/publication/31288947}, author = {Gallyas, Ferenc and Sümegi, Balázs}, doi = {10.3390/ijms21082767}, journal-iso = {INT J MOL SCI}, journal = {INTERNATIONAL JOURNAL OF MOLECULAR SCIENCES}, volume = {21}, unique-id = {31288947}, issn = {1661-6596}, abstract = {Inhibitors of the nuclear DNA damage sensor and signalling enzyme poly(ADP-ribose) polymerase (PARP) have recently been introduced in the therapy of cancers deficient in double-strand DNA break repair systems, and ongoing clinical trials aim to extend their use from other forms of cancer non-responsive to conventional treatments. Additionally, PARP inhibitors were suggested to be repurposed for oxidative stress-associated non-oncological diseases resulting in a devastating outcome, or requiring acute treatment. Their well-documented mitochondria- and cytoprotective effects form the basis of PARP inhibitors' therapeutic use for non-oncological diseases, yet can limit their efficacy in the treatment of cancers. A better understanding of the processes involved in their protective effects may improve the PARP inhibitors' therapeutic potential in the non-oncological indications. To this end, we endeavoured to summarise the basic features regarding mitochondrial structure and function, review the major PARP activation-induced cellular processes leading to mitochondrial damage, and discuss the role of PARP inhibition-mediated mitochondrial protection in several oxidative stress-associated diseases.}, keywords = {APOPTOSIS; AKT; AIF; Cell Death; MAPK; ROS; MPT}, year = {2020}, eissn = {1422-0067}, orcid-numbers = {Gallyas, Ferenc/0000-0002-1906-4333} } @article{MTMT:31202699, title = {Role of Akt Activation in PARP Inhibitor Resistance in Cancer}, url = {https://m2.mtmt.hu/api/publication/31202699}, author = {Gallyas, Ferenc and Sümegi, Balázs and Szabo, Csaba}, doi = {10.3390/cancers12030532}, journal-iso = {CANCERS}, journal = {CANCERS}, volume = {12}, unique-id = {31202699}, abstract = {Poly(ADP-ribose) polymerase (PARP) inhibitors have recently been introduced in the therapy of several types of cancers not responding to conventional treatments.

Activity of the cytoprotective phosphatidylinositol-3 kinase (PI3K)-Akt pathway is often increased in human cancer that could result from mutation, expressional change, or amplification of upstream growth-related factor signaling elements or elements of the Akt pathway itself. However, PARP-inhibitor-induced activation of the cytoprotective PI3K-Akt pathway is overlooked, although it likely contributes to the development of PARP inhibitor resistance. Here, we briefly summarize the biological role of the PI3K-Akt pathway.
