The loss of proteostasis is a hallmark of aging. Whether proteostasis loss plays a role in muscle aging remains elusive. To address this question we collected muscles, Soleus (SOL, type I) and Extensor digitorum longus (EDL, type II), from young (4 months) and old (25 months) C57BL/6 mice and evaluated the proteasomal system. Initial work showed decreased 26 S activity in old SOL. EDL displayed lower proteasomal activity in both ages compared to any of the SOL ages. Moreover, in order to understand if during aging there is the so-called "fiber switch from fast-to-slow", we performed western blots against sMHC and fMHC (slow and fast myosin heavy chain, respectively). Preliminary results suggest that young SOL is composed by slow twitch fibers but also contains fast twitch fibers, while young EDL seems to be mostly composed by fast twitch fibers that level down during aging, suggesting the switch. As a conclusion, EDL seems to have less proteasomal activity, however, if this is a contributor or a consequence to the muscle fiber switch during aging still needs further investigation.}, language = {en} } @misc{DoegeSchumacherBalzusetal.2017, author = {D{\"o}ge, Nadine and Schumacher, Fabian and Balzus, Benjamin and Colombo, Miriam and Hadam, Sabrina and Rancan, Fiorenza and Blume-Peytavi, Ulrike and Kleuser, Burkhard and Bodmeier, Roland and Vogt, Annika}, title = {Particle- based formulations and controlled skin barrier disruption have a signifi cant impact on the delivery and penetration kinetics of dexamethasone as assessed in an ex vivo microdialysis}, series = {Journal der Deutschen Dermatologischen Gesellschaft}, volume = {15}, journal = {Journal der Deutschen Dermatologischen Gesellschaft}, publisher = {Wiley}, address = {Berlin}, issn = {1610-0379}, pages = {182 -- 182}, year = {2017}, abstract = {Preclinical assessment of penetration not only in intact, but also in barrier-disrupted skin is important to explore the surplus value of novel drug delivery systems, which can be specifically designed for diseased skin. Here, we characterized physical and chemical barrier disruption protocols for short-term ex vivo skin cultures with regard to structural integrity, physiological and biological parameters. Further, we compared the penetration of dexamethasone (Dex) in different nanoparticle-based formulations in stratum corneum, epidermis and dermis extracts of intact vs. barrier-disrupted skin as well as by dermal microdialysis at 6, 12 and 24 hours after topical application. Dex was quantified by liquid-chromatography - tandem-mass spectrometry (LC-MS/MS). Simultaneously, we investigated the Dex efficacy by interleukin (IL) analysis. Tape-stripping (TS) and 4 hours sodium lauryl sulfate 5 \% (SLS) exposure were identified as highly effective barrier disruption methods assessed by reproducible transepidermal water loss (TEWL) changes and IL-6/8 increase which was more pronounced in SLS-treated skin. The barrier state has also a significant impact on the Dex penetration kinetics: for all formulations, TS highly increased dermal Dex concentration despite the fact that nanocrystals quickly and effectively penetrated both, intact and barrier-disrupted skin reaching significantly higher dermal Dex concentration after 6 hours compared to Dex cream. The surplus value of encapsulation in ethyl cellulose nanocarriers could mostly be observed when applied on intact skin, in general showing a delayed Dex penetration. Estimation of cytokines was limited due to the trauma caused by probe insertion. In summary, ex vivo human skin is a highly interesting short-term preclinical model for the analysis of penetration and efficacy of novel drug delivery systems.}, language = {en} } @misc{DoegeHoenzkeSchumacheretal.2016, author = {Doege, N. and Hoenzke, S. and Schumacher, Fabian and Balzus, Benjamin and Colombo, Miriam and Hadam, S. and Rancan, F. and Blume-Peytavi, Ulrike and Schindler, A. and Ruehl, E. and Skov, P. and Church, Martin K. and Hedtrich, Sarah and Kleuser, Burkhard and Bodmeier, Roland and Vogt, A.}, title = {Ex vivo microdialysis used for the preclinical assessment of anti-inflammatory therapy}, series = {Experimental dermatology : the official journal of the European Immunodermatology Society}, volume = {25}, journal = {Experimental dermatology : the official journal of the European Immunodermatology Society}, publisher = {Wiley-Blackwell}, address = {Hoboken}, issn = {0906-6705}, pages = {E32 -- E32}, year = {2016}, language = {en} } @misc{ChenBornhorstNeelyetal.2018, author = {Chen, Pan and Bornhorst, Julia and Neely, M.
