Fig 1: Western blot results. (A) Western blot analysis of SNTA1 and AQP4 protein expression in Group C, Group PDN, and Group BHB. (B) Relative protein expression of SNTA1 and AQP4. Due to the reason that some blots in the original saved images were not mentioned in the present study, we spliced the blots and the typical ones were chosen to indicate the differences in the expression of proteins. Refer to Figure 1 for the meaning of the grouping abbreviation. Values were presented as mean ± SEM. *p < 0.05 compared with values in Group PDN. #p < 0.05 compared with values in Group C. SNTA1 means a-syntrophin, and AQP4 means aquaporin-4 protein.
