Relocalized redox-active lysosomal iron is an important mediator of oxidative-stress-induced DNA damage
Oxidative damage to nuclear DNA is known to involve site-specific Fenton-type chemistry catalysed by redox-active iron or copper in the immediate vicinity of DNA. However, the presence of transition metals in the nucleus has not been shown convincingly. Recently, it was proposed that a major part of the cellular pool of loose iron is confined within the acidic vacuolar compartment [Yu, Persson, Eaton and Brunk (2003) Free Radical Biol. Med. 34, 1243-1252; Persson, Yu, Tirosh, Eaton and Brunk (2003) Free Radical Biol. Med. 34, 1295-1305]. Consequently, rupture of secondary lysosomes, as well as subsequent relocation of labile iron to the nucleus, could be an important intermediary step in the generation of oxidative damage to DNA. To test this concept we employed the potent iron chelator DFO (desferrioxamine) conjugated with starch to form an HMM-DFO (high-molecular-mass DFO complex). The HMM-DFO complex will enter cells only via fluid-phase endocytosis and remain within the acidic vacuolar compartment, thereby chelating redox-active iron exclusively inside the endosomal/lysosomal compartment. Both free DFO and HMM-DFO equally protected lysosomal-membrane integrity against H2O 2-induced oxidative disruption. More importantly, both forms of DFO prevented H2O2-induced strand breaks in nuclear DNA, including telomeres. To exclude the possibility that lysosomal hydrolases, rather than iron, caused the observed DNA damage, limited lysosomal rupture was induced using the lysosomotropic detergent O-methyl-serine dodecylamine hydrochloride; subsequently, hardly any DNA damage was found. These observations suggest that rapid oxidative damage to cellular DNA is minimal in the absence of redox-active iron and that oxidant-mediated DNA damage, observed in normal cells, is mainly derived from intralysosomal iron translocated to the nucleus after lysosomal rupture

Copyright Issues Got You Down?: Updates from the Scholarly Communications Working Group
The use and creating of research are integral parts of faculty’s teaching and scholarship, but navigating the ins and outs of copyright issues, the allowances and exclusions, can be overwhelming. During this workshop, participants will hear about what UT Tyler’s Scholarly Communications working group has developed for faculty, including information relating to author rights, copyright, fair use, open access, creating access to faculty scholarship through Scholar Works at UT Tyler, and the use of open textbooks and other free course materials

Subscription, Interlibrary Loan, or Nothing: How to Ensure Global Access to Your Scholarly Works
Publishing through traditional journals often limits access to your scholarship — researchers can only read your works through a journal subscription, via available library databases, interlibrary loan, or pay the publisher for access. This workshop will show how faculty can use Scholar Works at UT Tyler to store, preserve and provide worldwide access to their scholarly output. A discussion about open access, including: copyright agreements, author rights, avoiding predatory journals, and benefits of adding content to Scholar Works at UT Tyler. Bring your CV and we can review specific copyright policies of your published works
