Figure Lengend Snippet: O -GlcNAc, O -GlcNAc transferase (OGT), MOF (KAT8), and ATM levels were elevated in aged aorta tissues. (A) Illustration of mouse aorta tissue. (B) Immunofluorescence staining of OGT (red) and ATM (pS/Tq, green), which indicates ATM/ATR activity in young (6 months) and old (21 months) mouse aorta tissue. (C) Quantification of OGT mean fluorescence in young (n=39) and old mice (n=49). (D) Immunofluorescence staining of O -GlcNAc (red) and actin (green). (E) Quantification of O -GlcNAc mean fluorescence in young (n=63) and old mice (n=63). (F) Immunofluorescence staining of ATM (pS/Tq, red) and actin (green). (G) Quantification of ATM mean fluorescence in young (n=39) and old mice (n=53). (H) Immunofluorescence staining of H2AX (red) and actin (green). (I) Quantification of ATM mean fluorescence in young (n=56) and old mice (n=69). (J) Immunofluorescence staining of MOF (red) and ATM (pS/Tq, green), which indicates ATM/ATR activity. (K) Quantification of MOF mean fluorescence in young (n=35) and old mice (n=45). The white line indicates the width of the aorta. The insert in each panel is an enlarged image of the area where the line is displayed. Data are presented as the mean±SD. **** P <0.0001. ns, non-significant. ATM, ataxia telangiectasia mutated.
