In vitro streptozotocin model for modeling Alzheimer-like changes : effect on amyloid precursor protein secretases and glycogen synthase kinase-3
There is accumulating evidence for a pathogenetic link between sporadic Alzheimer’s disease (AD) and diabetes mellitus (DM). At subdiabetogenic doses, the cerebral administration of the diabetogenic substance streptozotocin (STZ) induces an insulin-resistant brain state (IRBS). The aim of the presen...

| 520 | |a There is accumulating evidence for a pathogenetic link between sporadic Alzheimer’s disease (AD) and diabetes mellitus (DM). At subdiabetogenic doses, the cerebral administration of the diabetogenic substance streptozotocin (STZ) induces an insulin-resistant brain state (IRBS). The aim of the present pilot study was to investigate the effect of STZ on Alzheimer-like characteristics such as amyloid precursor protein (APP) cleavage secretases, betaA4 fragment, and glycogen synthase kinase (GSK) in vitro. Different STZ concentrations (0-5 mM) and incubation intervals (0-48 h) were tested to find appropriate cell culture conditions for further biochemical analyses in human neuroblastoma cells (SK-N-MC). Lactate dehydrogenase (LDH) was measured spectrophotometrically. Intracellular ATP was determined using bioluminescent luciferase assay. Secretase activity (alpha, beta, and gamma) was measured by employing commercial fluorometric secretase activity assay kits, betaA4 fragment by immunoprecipitation. Glycogen synthase kinase-3alpha/beta (total and phospho-GSK) content was assayed by ELISA technique. In vitro STZ administration (1 mM) induced a significant reduction in intracellular ATP concentration without pronounced cell death after 24 and 48 h as measured by LDH. Under these experimental conditions, a significant increase in beta-secretase and a significant drop in alpha-secretase were obtained, whereas gamma-secretase was not changed significantly. Simultaneously, the betaA4 concentration was increased by about threefold. Furthermore, STZ significantly increased total GSK and markedly decreased phospho-GSK. A direct link between STZ, intracellular ATP deficit, and Alzheimer-related enzymes was shown in this in vitro pilot study. Thus, these results support the hypothesis that sporadic AD is being recognized as an IRBS, which can be modulated by in vitro STZ model. Continuing investigations relating pathogenetic mechanisms and AD-like hallmarks are necessary to modulate different cascades of the IRBS using in vitro models. | ||

Continuing investigations relating pathogenetic mechanisms and AD-like hallmarks are necessary to modulate different cascades of the IRBS using in vitro models. 2014 Kopitz, Jürgen verfasserin (DE-588)1033923397 (DE-627)743674472 (DE-576)16530393X aut Enthalten in Journal of neural transmission Wien [u.a.] : Springer, 1950 122(2015), 4, Seite 551-557 Online-Ressource (DE-627)300185901 (DE-600)1481655-6 (DE-576)09450542X 1435-1463 nnns volume:122 year:2015 number:4 pages:551-557 extent:7 https://doi.org/10.1007/s00702-014-1319-7 Verlag Resolving-System lizenzpflichtig Volltext https://link.springer.com/article/10.1007/s00702-014-1319-7 Verlag Resolving-System lizenzpflichtig Volltext GBV_USEFLAG_U GBV_ILN_2013 ISIL_DE-16-250 SYSFLAG_1 GBV_KXP SSG-OLC-PHA GBV_ILN_11 GBV_ILN_20 GBV_ILN_22 GBV_ILN_23 GBV_ILN_24 GBV_ILN_31 GBV_ILN_32 GBV_ILN_39 GBV_ILN_40 GBV_ILN_60 GBV_ILN_62 GBV_ILN_63 GBV_ILN_69 GBV_ILN_70 GBV_ILN_73 GBV_ILN_74 GBV_ILN_90 GBV_ILN_95 GBV_ILN_100 GBV_ILN_101 GBV_ILN_105 GBV_ILN_110 GBV_ILN_120 GBV_ILN_138 GBV_ILN_150 GBV_ILN_151 GBV_ILN_152 GBV_ILN_161 GBV_ILN_170 GBV_ILN_171 GBV_ILN_187 GBV_ILN_213 GBV_ILN_224 GBV_ILN_230 GBV_ILN_250 GBV_ILN_267 GBV_ILN_281 GBV_ILN_285 GBV_ILN_293 GBV_ILN_370 GBV_ILN_602 GBV_ILN_636 GBV_ILN_702 GBV_ILN_2001 GBV_ILN_2003 GBV_ILN_2004 GBV_ILN_2005 GBV_ILN_2006 GBV_ILN_2007 GBV_ILN_2008 GBV_ILN_2009 GBV_ILN_2010 GBV_ILN_2011 GBV_ILN_2014 GBV_ILN_2015 GBV_ILN_2020 GBV_ILN_2021 GBV_ILN_2025 GBV_ILN_2026 GBV_ILN_2027 GBV_ILN_2031 GBV_ILN_2034 GBV_ILN_2037 GBV_ILN_2038 GBV_ILN_2039 GBV_ILN_2044 GBV_ILN_2048 GBV_ILN_2049 GBV_ILN_2050 GBV_ILN_2055 GBV_ILN_2057 GBV_ILN_2059 GBV_ILN_2061 GBV_ILN_2064 GBV_ILN_2065 GBV_ILN_2068 GBV_ILN_2070 GBV_ILN_2086 GBV_ILN_2088 GBV_ILN_2093 GBV_ILN_2106 GBV_ILN_2107 GBV_ILN_2108 GBV_ILN_2110 GBV_ILN_2111 GBV_ILN_2112 GBV_ILN_2113 GBV_ILN_2116 GBV_ILN_2118 GBV_ILN_2119 GBV_ILN_2122 GBV_ILN_2129 GBV_ILN_2143 GBV_ILN_2144 GBV_ILN_2147 GBV_ILN_2148 GBV_ILN_2152 GBV_ILN_2153 GBV_ILN_2188 GBV_ILN_2190 GBV_ILN_2232 GBV_ILN_2336 GBV_ILN_2446 GBV_ILN_2470 GBV_ILN_2472 GBV_ILN_2507 GBV_ILN_2522 GBV_ILN_2548 GBV_ILN_4012 GBV_ILN_4035 GBV_ILN_4037 GBV_ILN_4046 GBV_ILN_4112 GBV_ILN_4125 GBV_ILN_4126 GBV_ILN_4242 GBV_ILN_4246 GBV_ILN_4249 GBV_ILN_4251 GBV_ILN_4305 GBV_ILN_4306 GBV_ILN_4307 GBV_ILN_4313 GBV_ILN_4322 GBV_ILN_4323 GBV_ILN_4324 GBV_ILN_4325 GBV_ILN_4326 GBV_ILN_4328 GBV_ILN_4333 GBV_ILN_4334 GBV_ILN_4335 GBV_ILN_4336 GBV_ILN_4338 GBV_ILN_4393 GBV_ILN_4700 AR 122 2015 4 551-557 7 2013 01 DE-16-250 371019086X 00 --%%-- --%%-- --%%-- --%%-- l01 08-07-20 2013 01 DE-16-250 00 s hd2015 2013 01 DE-16-250 01 s (DE-627)1410508463 wissenschaftlicher Artikel (Zeitschrift) 2013 01 DE-16-250 02 s per_2 2013 01 DE-16-250 03 s s_7 2013 01 DE-16-250 04 p (DE-627)1484064054 Plaschke, Konstanze 2013 01 DE-16-250 04 k (DE-627)1416740899 Universitätsklinik für Anästhesiologie 2013 01 DE-16-250 04 s (DE-627)1410501914 Verfasser 2013 01 DE-16-250 04 s pos_1 2013 01 DE-16-250 05 p (DE-627)1451604467 Kopitz, Jürgen 2013 01 DE-16-250 05 k (DE-627)1416741658 Pathologisches Institut 2013 01 DE-16-250 05 s (DE-627)1410501914 Verfasser 2013 01 DE-16-250 05 s pos_2 |

At subdiabetogenic doses, the cerebral administration of the diabetogenic substance streptozotocin (STZ) induces an insulin-resistant brain state (IRBS). The aim of the present pilot study was to investigate the effect of STZ on Alzheimer-like characteristics such as amyloid precursor protein (APP) cleavage secretases, betaA4 fragment, and glycogen synthase kinase (GSK) in vitro. Different STZ concentrations (0-5 mM) and incubation intervals (0-48 h) were tested to find appropriate cell culture conditions for further biochemical analyses in human neuroblastoma cells (SK-N-MC). Lactate dehydrogenase (LDH) was measured spectrophotometrically. Intracellular ATP was determined using bioluminescent luciferase assay. Secretase activity (alpha, beta, and gamma) was measured by employing commercial fluorometric secretase activity assay kits, betaA4 fragment by immunoprecipitation. Glycogen synthase kinase-3alpha/beta (total and phospho-GSK) content was assayed by ELISA technique. In vitro STZ administration (1 mM) induced a significant reduction in intracellular ATP concentration without pronounced cell death after 24 and 48 h as measured by LDH. Under these experimental conditions, a significant increase in beta-secretase and a significant drop in alpha-secretase were obtained, whereas gamma-secretase was not changed significantly. Simultaneously, the betaA4 concentration was increased by about threefold. Furthermore, STZ significantly increased total GSK and markedly decreased phospho-GSK. A direct link between STZ, intracellular ATP deficit, and Alzheimer-related enzymes was shown in this in vitro pilot study. Thus, these results support the hypothesis that sporadic AD is being recognized as an IRBS, which can be modulated by in vitro STZ model.

Lactate dehydrogenase (LDH) was measured spectrophotometrically. Intracellular ATP was determined using bioluminescent luciferase assay. Secretase activity (alpha, beta, and gamma) was measured by employing commercial fluorometric secretase activity assay kits, betaA4 fragment by immunoprecipitation. Glycogen synthase kinase-3alpha/beta (total and phospho-GSK) content was assayed by ELISA technique. In vitro STZ administration (1 mM) induced a significant reduction in intracellular ATP concentration without pronounced cell death after 24 and 48 h as measured by LDH. Under these experimental conditions, a significant increase in beta-secretase and a significant drop in alpha-secretase were obtained, whereas gamma-secretase was not changed significantly. Simultaneously, the betaA4 concentration was increased by about threefold. Furthermore, STZ significantly increased total GSK and markedly decreased phospho-GSK. A direct link between STZ, intracellular ATP deficit, and Alzheimer-related enzymes was shown in this in vitro pilot study. Thus, these results support the hypothesis that sporadic AD is being recognized as an IRBS, which can be modulated by in vitro STZ model. Continuing investigations relating pathogenetic mechanisms and AD-like hallmarks are necessary to modulate different cascades of the IRBS using in vitro models. 2014 Kopitz, Jürgen verfasserin (DE-588)1033923397 (DE-627)743674472 (DE-576)16530393X aut Enthalten in Journal of neural transmission Wien [u.a.] : Springer, 1950 122(2015), 4, Seite 551-557 Online-Ressource (DE-627)300185901 (DE-600)1481655-6 (DE-576)09450542X 1435-1463 nnns volume:122 year:2015 number:4 pages:551-557 extent:7 https://doi.org/10.1007/s00702-014-1319-7 Verlag Resolving-System lizenzpflichtig Volltext https://link.springer.com/article/10.1007/s00702-014-1319-7 Verlag Resolving-System lizenzpflichtig Volltext GBV_USEFLAG_U GBV_ILN_2013 ISIL_DE-16-250 SYSFLAG_1 GBV_KXP SSG-OLC-PHA GBV_ILN_11 GBV_ILN_20 GBV_ILN_22 GBV_ILN_23 GBV_ILN_24 GBV_ILN_31 GBV_ILN_32 GBV_ILN_39 GBV_ILN_40 GBV_ILN_60 GBV_ILN_62 GBV_ILN_63 GBV_ILN_69 GBV_ILN_70 GBV_ILN_73 GBV_ILN_74 GBV_ILN_90 GBV_ILN_95 GBV_ILN_100 GBV_ILN_101 GBV_ILN_105 GBV_ILN_110 GBV_ILN_120 GBV_ILN_138 GBV_ILN_150 GBV_ILN_151 GBV_ILN_152 GBV_ILN_161 GBV_ILN_170 GBV_ILN_171 GBV_ILN_187 GBV_ILN_213 GBV_ILN_224 GBV_ILN_230 GBV_ILN_250 GBV_ILN_267 GBV_ILN_281 GBV_ILN_285 GBV_ILN_293 GBV_ILN_370 GBV_ILN_602 GBV_ILN_636 GBV_ILN_702 GBV_ILN_2001 GBV_ILN_2003 GBV_ILN_2004 GBV_ILN_2005 GBV_ILN_2006 GBV_ILN_2007 GBV_ILN_2008 GBV_ILN_2009 GBV_ILN_2010 GBV_ILN_2011 GBV_ILN_2014 GBV_ILN_2015 GBV_ILN_2020 GBV_ILN_2021 GBV_ILN_2025 GBV_ILN_2026 GBV_ILN_2027 GBV_ILN_2031 GBV_ILN_2034 GBV_ILN_2037 GBV_ILN_2038 GBV_ILN_2039 GBV_ILN_2044 GBV_ILN_2048 GBV_ILN_2049 GBV_ILN_2050 GBV_ILN_2055 GBV_ILN_2057 GBV_ILN_2059 GBV_ILN_2061 GBV_ILN_2064 GBV_ILN_2065 GBV_ILN_2068 GBV_ILN_2070 GBV_ILN_2086 GBV_ILN_2088 GBV_ILN_2093 GBV_ILN_2106 GBV_ILN_2107 GBV_ILN_2108 GBV_ILN_2110 GBV_ILN_2111 GBV_ILN_2112 GBV_ILN_2113 GBV_ILN_2116 GBV_ILN_2118 GBV_ILN_2119 GBV_ILN_2122 GBV_ILN_2129 GBV_ILN_2143 GBV_ILN_2144 GBV_ILN_2147 GBV_ILN_2148 GBV_ILN_2152 GBV_ILN_2153 GBV_ILN_2188 GBV_ILN_2190 GBV_ILN_2232 GBV_ILN_2336 GBV_ILN_2446 GBV_ILN_2470 GBV_ILN_2472 GBV_ILN_2507 GBV_ILN_2522 GBV_ILN_2548 GBV_ILN_4012 GBV_ILN_4035 GBV_ILN_4037 GBV_ILN_4046 GBV_ILN_4112 GBV_ILN_4125 GBV_ILN_4126 GBV_ILN_4242 GBV_ILN_4246 GBV_ILN_4249 GBV_ILN_4251 GBV_ILN_4305 GBV_ILN_4306 GBV_ILN_4307 GBV_ILN_4313 GBV_ILN_4322 GBV_ILN_4323 GBV_ILN_4324 GBV_ILN_4325 GBV_ILN_4326 GBV_ILN_4328 GBV_ILN_4333 GBV_ILN_4334 GBV_ILN_4335 GBV_ILN_4336 GBV_ILN_4338 GBV_ILN_4393 GBV_ILN_4700 AR 122 2015 4 551-557 7 2013 01 DE-16-250 371019086X 00 --%%-- --%%-- --%%-- --%%-- l01 08-07-20 2013 01 DE-16-250 00 s hd2015 2013 01 DE-16-250 01 s (DE-627)1410508463 wissenschaftlicher Artikel (Zeitschrift) 2013 01 DE-16-250 02 s per_2 2013 01 DE-16-250 03 s s_7 2013 01 DE-16-250 04 p (DE-627)1484064054 Plaschke, Konstanze 2013 01 DE-16-250 04 k (DE-627)1416740899 Universitätsklinik für Anästhesiologie 2013 01 DE-16-250 04 s (DE-627)1410501914 Verfasser 2013 01 DE-16-250 04 s pos_1 2013 01 DE-16-250 05 p (DE-627)1451604467 Kopitz, Jürgen 2013 01 DE-16-250 05 k (DE-627)1416741658 Pathologisches Institut 2013 01 DE-16-250 05 s (DE-627)1410501914 Verfasser 2013 01 DE-16-250 05 s pos_2 |

In vitro streptozotocin model for modeling Alzheimer-like changes effect on amyloid precursor protein secretases and glycogen synthase kinase-3 |
| abstract |
There is accumulating evidence for a pathogenetic link between sporadic Alzheimer’s disease (AD) and diabetes mellitus (DM). At subdiabetogenic doses, the cerebral administration of the diabetogenic substance streptozotocin (STZ) induces an insulin-resistant brain state (IRBS). The aim of the present pilot study was to investigate the effect of STZ on Alzheimer-like characteristics such as amyloid precursor protein (APP) cleavage secretases, betaA4 fragment, and glycogen synthase kinase (GSK) in vitro. Different STZ concentrations (0-5 mM) and incubation intervals (0-48 h) were tested to find appropriate cell culture conditions for further biochemical analyses in human neuroblastoma cells (SK-N-MC). Lactate dehydrogenase (LDH) was measured spectrophotometrically. Intracellular ATP was determined using bioluminescent luciferase assay. Secretase activity (alpha, beta, and gamma) was measured by employing commercial fluorometric secretase activity assay kits, betaA4 fragment by immunoprecipitation. Glycogen synthase kinase-3alpha/beta (total and phospho-GSK) content was assayed by ELISA technique. In vitro STZ administration (1 mM) induced a significant reduction in intracellular ATP concentration without pronounced cell death after 24 and 48 h as measured by LDH. Under these experimental conditions, a significant increase in beta-secretase and a significant drop in alpha-secretase were obtained, whereas gamma-secretase was not changed significantly. Simultaneously, the betaA4 concentration was increased by about threefold. Furthermore, STZ significantly increased total GSK and markedly decreased phospho-GSK. A direct link between STZ, intracellular ATP deficit, and Alzheimer-related enzymes was shown in this in vitro pilot study. Thus, these results support the hypothesis that sporadic AD is being recognized as an IRBS, which can be modulated by in vitro STZ model. Continuing investigations relating pathogenetic mechanisms and AD-like hallmarks are necessary to modulate different cascades of the IRBS using in vitro models.
