1 M phosphate buffer, pH 7. 4, at 4 C overnight. After fixation and dehydration, 70 nm sections were pre pared with a diamond blade, using an ultramicrotome and mounted on metal grids. These were stained with 2% uranyl acetate Tipifarnib cancer and secon darily stained with lead solution and examined with a transmission electron Inhibitors,Modulators,Libraries microscope. Specimens were examined as previ ously described. Briefly, a minimum of 8 to 10 random fields were exami ned at 2,500 magnification for evidence of autophagy or cell injury death, and the number of autophagosomes and autolysosomes in each 2,500 image was counted. The mean SD per 50 images from each mouse was calculated and the data from different groups were compaired versus sham. In the present study, autophagosomes were defined as double membrane structures that enclosed cytoplasm with damaged organelles in various stages of degrad ation.

double membrane structures enclosing only mate rials that resembled background cytoplasm were not counted. Autolysosomes were defined as single mem brane vesicles with cytoplasmic Inhibitors,Modulators,Libraries or organellar debris in various stages of degradation. Lysosomes with amorphous electron dense material were not counted. Inhibitors,Modulators,Libraries Be cause initial counting of images was performed by the same investigator who created the images, the pos sibility of unintended bias was mitigated by providing the same set of images in a blinded fashion to a second investigator. When results of initial counting differed markedly between observers, relevant images were re evaluated and discrepancies were resolved.

The 2,500 survey images Inhibitors,Modulators,Libraries used in this analysis represent approximately 3,000 square microns of tissue, each containing 5 to 8 hepatocytes and a variable comple ment of Kupffer cells, stellate cells, sinusoidal endothe lial cells and inflammatory cells. Only the hepatocytes were counted. Histological analysis Liver tissue specimens were obtained and sections of formalin fixed paraffin embedded liver samples were stained with hematoxylin eosin to assess the degree of liver injury. Analysis of transaminase to assess liver injury Blood samples were obtained from the tail arteries of mice. Serum aspartate aminotransferase and alanine aminotransferase activity was quanti fied using the transaminase C ll test. Statistical analysis All data were analyzed for statistical significance using the Mann Whitney test or one way analysis of variance, and individual group means were then compared with a Student Newman Keuls test.

All data were expressed as the mean SD using the statistical software program PRISM. Overall survival was calculated using the Kaplan Meier method, and comparisons were evaluated using the log Inhibitors,Modulators,Libraries rank test. Data were analyzed using SPSS 21. 0 soft ware. P values 0. 05 were considered to be statistically significant.
