Characterization of p53 in the AG flies. (a) Co-immunoprecipitation of Hsp26/Hsp27 with p53. The homogenized fly heads were immunoprecipitated with anti-Hsp26 or anti-Hsp27 antibodies and probed with anti-Hsp26, anti-Hsp27, anti-p53 antibody, with anti-IgG as a control. The input of actin is the protein loading control. The genotypes of flies are indicated on the image. Trial n = 2. (b) Accumulation of p53 in the AG adult flies. The control (AG flies at 18 °C) p53 protein level is set as 1, and the indicated genotype flies relative to the control are shown. Trial n = 3. (c) Accumulation of p53 in the larval AG brain. The images show immunostaining with anti-p53 and anti-GluR1 antibodies. The nuclei are stained with DAPI. The result showed that the 53 protein (the red channel) was lower in the control (Appl-Gal4) ventral nerve cord of larval flies; whereas p53 protein level was higher in the AG flies, especially in neurons with higher GluR1 expression (the green channel). Trial n = 2. (d) Effect of p53 on AG fly survival. The survival rate of indicated genotype of flies is shown. Trial n = 4.
