Conference Object Alteration in Redox Homeostasis in Early-Onset Tay-Sachs Disease Mouse Model(Academic Press, 2020) Seyrantepe, Volkan; Ateş, Nurselin; Başırlı, Hatice Hande; Demir, Seçil Akyıldız; Dağalp, Berkay; Nalbant, Ayten; Çalışkan, Tufan UtkuTay-Sachs disease is an autosomal recessively inherited lysosomal disorder. It is caused by mutations on the HEXA gene encoding α-subunit of β-Hexosaminidase A enzyme. The enzyme normally catalyzes GM2 to GM3 conversion but when it is absent or dysfunctional the GM2 degradation is interrupted. The undegraded GM2 ganglioside is progressively accumulated especially in neurons and causes neurodegenaration at the end. The Hexa−/− mice generated as Tay-Sachs model was nearly normal and a bypass mechanism mediated by a sialidase was suggested. Recently we determined that Neu3 sialidase involves in ganglioside degradation in the Tay-Sachs disease pathology and the Hexa−/-Neu3−/− mice mimic the neuropathologic and clinical phenotype of the disease. It was reported that oxidative stress is triggered in neurodegenerative diseases and several lysosomal disorders. It is caused by the imbalance between antioxidant defence mechanism and production of reactive oxygen species (ROS). ROS have high chemical reactivity which react and damage DNA, protein, carbohydrates and lipids.Data Paper Citation - WoS: 3Citation - Scopus: 3Small Rna Data Set That Includes Trna-Derived Fragments From Jurkat Cells Treated With Camptothecin(Elsevier Ltd., 2018) Coşacak, Mehmet İlyas; Erdoğan, İpek; Nalbant, Ayten; Akgül, BünyaminIn this article, we report a small RNA data set obtained from human T cell acute leukemia Jurkat cells, which were treated with the universal apoptotic agent camptothecin. Based on the Annexin-V labeling pattern, we sorted two Jurkat subpopulations in treated cells: one that is sensitive to the drug and the other being relatively more resistant. We report new original data that include the frequency of tRNA-derived fragments (tRF) in drug-sensitive and resistant cells. We also present partially analyzed data to show the origin of reads on tRNAs as well as the borders of the fragments. We believe that this data can benefit the science community working in the field of tRF and/or apoptosis.
