16043017uch l1uch l11.0because oxidative modification can lead to structural alteration and activity decline our current study suggests that oxidative modification of uch l1 tctp sod1 and possibly b crystallin may play an important role in the neurodegeneration of als.  
16043017uch l1uch l11.0ubiquitin carboxyl terminal hydrolase l1 uch l1 assay  
16043017uch l1uch l11.0the activities of uch l1 in the spinal cord were measured by determining the rate of conversion of ubiquitin c terminal 7 amido 4 methylcoumarin ub amc calbiochem to ubiquitin and free amc [48] .  
16043017uch l1uch l11.0uch l1 activities of each individual were assayed by the change of _amp_#x3bb; em 460 nm over time.  
16043017uch l1uch l11.0the average uch l1 activities of six transgenic animals were compared to those of six control animals using student's t test.  
16043017uch l1uch l11.0these proteins were identified as sod1 translationally controlled tumor protein tctp uch l1 and b crystallin.  
16043017uch l1uch l11.0we report here that the specific carbonyl levels of human sod1 tctp uch l1 and possibly b crystallin are significantly increased in the spinal cord of g93a sod1 transgenic mice compared to that of nontransgenic mice.  
16043017uch l1uch l11.0in order to confirm that oxidative modification inactivated protein activity we compared the activity of uch l1 in the g93a sod1 transgenic mice to that in the control mice.  
16043017uch l1uch l11.0consistent with our prior studies that demonstrate loss of activity of oxidatively modified proteins [49] [50] and [51] uch l1 activity was significantly decreased 29% in the g93a sod1 transgenic mice compared to that of nontransgenic control fig 4 .  
16043017uch l1uch l11.0in the current study we identified the proteins that demonstrate increased carbonyl levels compared to those of the nontransgenic mice as sod1 tctp uch l1 and b crystallin.  
16043017uch l1uch l11.0uch l1 belongs to a family of ubiquitin carboxyl terminal hydrolases that play important roles in the ubiquitin_amp_#x2013;proteolytic pathway [71] .  
16043017uch l1uch l11.0loss of uch l1 function causes neuroaxonal dystrophy [74] [75] and [76] significant protein oxidization [45] and accumulation of synuclein protein in gracile axonal dystrophy mice [77] .  
16043017uch l1uch l11.0similarly decreased uch l1 activity by mutation also enhances protein aggregation in escherichia coli [78] .  
16043017uch l1uch l11.0therefore based on the prior literature oxidative inactivation of uch l1 presented in the current study possibly contributes to both the protein aggregation and the oxidative stress observed in g93a sod1 transgenic mice and als patients.  
16043017uch l1uch l11.0consistent with this notion and consistent with our finding fig 4 that uch l1 activity is decreased in g93a sod1 mouse spinal cord the inclusions of human als and msod1 including g93a mice are excessively ubiquitinated [79] [80] [81] and [82] .  
16043017uch l1uch l11.0based on our current observations the increased oxidative modification of sod1 uch l1 and b crystallin plays a significant role in the protein aggregation in the spinal cords of g93a sod1 transgenic mice.  
16043017uch l1uch l11.0study provides insight into the mechanism of g93a sod1 neurotoxicity in vivo which involves oxidative modification of a ca 2+ regulating protein tctp and proteins involved in inclusion formation sod1 uch l1 and b crystallin suggesting a potential relationship between protein oxidation protein aggregation and ca 2+ regulation in als.  
16043017uch l1uch l11.0moreover one can speculate that the oxidative modification of these proteins impairs protein stability b crystallin ca 2+ binding tctp protein degradation uch l1 and antioxidant capacity sod1 .

16043017uch l1uch l11.0the activity of uch l1 is significantly decreased in the spinal cord of g93a sod1 transgenic mice compared to nontransgenic control.
