Sex specific differences in accumulation of protein aggregates following heat shock.Figure 4A) Experimental design of treatment by heat shock in mice. B) Western blot analysis of Ub-K48 proteins in the soluble fractions of intestine lysates from mice plus or minus heat shock. C) Quantification of panel B. Each central line and error bar indicate mean +/- SEM of a biological replicates (n=3 biological replicates per group). Data information: * indicates p<0.05, ** indicates p<0.005, and *** indicates p<0.0005 by unpaired two tailed students t-test comparing male and female samples or samples with or without heat shock. D) Western blot analysis of Ub-K48 proteins in the insoluble fraction of intestine lysates from mice plus or minus heat shock. E) Quantification of D. Each central line and error bar indicate mean +/- SEM of a biological replicates (n=3 biological replicates per group) Data information: * indicates p<0.05, ** indicates p<0.005, and *** indicates p<0.0005 by unpaired two tailed students t-test comparing male and female samples or samples with or without heat shock. F) Western blot analysis of Ub-K48 proteins in the soluble fractions of spinal cord lysates from mice plus or minus heat shock. G) Quantification of F. Each central line and error bar indicate mean +/- SEM of a biological replicates (n=3 biological replicates per group) Data information: * indicates p<0.05, ** indicates p<0.005, and *** indicates p<0.0005 by unpaired two tailed students t-test comparing male and female samples or samples with or without heat shock. H) Western blot analysis of Ub-K48 proteins in the insoluble fraction of spinal cord lysates from mice plus or minus heat shock. I) Quantification of H. Each central line and error bar indicate mean +/- SEM of a biological replicates (n=3 biological replicates per group) Data information: * indicates p<0.05, ** indicates p<0.005, and *** indicates p<0.0005 by unpaired two tailed students t-test comparing male and female samples or samples with or without heat shock. J) Model of gender specific protein aggregates accumulation following stress. K) Western blot of Ub-K48 proteins in the insoluble fraction of protein lysates of SOD1-G93A mouse spinal cord plus or minus heat shock. L) Quantification of panel K. Each central line and error bar indicate mean +/- SEM of a biological replicates (n=5 biological replicates per group) Data information: * indicates p<0.05, ** indicates p<0.005, and *** indicates p<0.0005 by unpaired two tailed students t-test comparing male and female samples or samples with or without heat shock. M) Chymotrypsin-like proteasome activity in spinal cord lysates from SOD1-G93A mice. Each central line and error bar indicate mean +/- SEM of a biological replicates (n=5 biological replicates per group). Bordered points indicate biological replicates and un-bordered points indicate technical replicates. Data information: * indicates p<0.05, ** indicates p<0.005, and *** indicates p<0.0005 by unpaired two tailed students t-test comparing male and female samples or samples with or without heat shock. N) Filter trap assay of protein lysates from the insoluble fraction of SOD1-G93A spinal cord lysates plus or minus heat shock. O) Quantification of panel N. Each central line and error bar indicate mean +/- SEM of a biological replicates (n=5 biological replicates per group) Data information: * indicates p<0.05, ** indicates p<0.005, and *** indicates p<0.0005 by unpaired two tailed students t-test comparing male and female samples or samples with or without heat shock. P) Representative transmission electron micrographs of protein aggregates in the insoluble fraction of SOD1-G93A spinal cord lysates plus or minus heat shock. Scale bar equals 600nm. Q) Quantification of P. (n=9 technical replicates per group) Data information: * indicates p<0.05, ** indicates p<0.005, and *** indicates p<0.0005 by unpaired two tailed students t-test comparing male and female samples or samples with or without heat shock.
