Figure Lengend Snippet: Overexpression of Toll, Spz, and Toll-Spz complex in S2 cells induces autophagy (A‒F) Detection of LC3-I, LC3-PE (LC3-II), and P62 proteins in S2 cells overexpressing Toll, Spz, and Toll-Spz complex by immunoblotting. S2 cells stably expressing RFP-GFP-LC3 were cultured in complete medium without treatment (control), or cultured in PBS instead of complete medium for 6 h (starved), or transfected with pMT-TIR-1-V5, pMT-TIR-7-V5 (A), pMT-Toll-1-V5, pMT-Toll-7-V5 (B), pMT-Spz-1-Flag, pMT-Spz-2-Flag, pMT-Spz-5-Flag, pMT-Spz-1FL-Flag (C), or pMT-GFP-V5 (D), or co-transfected with pMT-Toll-1-V5 or pMT-Toll-7-V5 with pMT-Spz-1-Flag, pMT-Spz-2-Flag, pMT-Spz-5-Flag, or pMT-Spz-1FL-Flag (E and F), then recombinant proteins were detected by mouse anti-V5 and mouse anti-Flag monoclonal antibodies, respectively. In these S2 cells, P62 protein was detected by anti-Ref(2)P antibody, LC3-I and LC3-II were detected by rabbit anti-LC3 polyclonal antibody, while tubulin was detected by mouse anti-tubulin monoclonal antibody. (G) Detection of Akt protein in S2 cells overexpressing Toll-Spz complex by immunoblotting. S2 cells stably expressing RFP-GFP-LC3 were treated as described above, total Akt (t-Akt) and phosphorylated Akt ( p -Akt) in cells were detected by rabbit anti-Akt and rabbit anti-phosphor-Akt ( p -Akt) polyclonal antibodies, respectively. Protein bands from at least 3 membranes were scanned for each protein using ImageJ. Data were represented as means ± SEM. Significant difference was determined by one way ANOVA followed by a Tukey’s multiple comparison tests using GraphPad Prism, with different letters indicating significant difference (p < 0.05) and identical letters for non-significant (p > 0.05). Significant difference was also determined by the student’s t test, ns for non-significant.

Figure Lengend Snippet: Insulin co-localizes with neuronal cells, leads to pAkt activation and subsequent reduction in HI-induced Cl-Caspase-3 positive cells in ipsilateral brain. Representative images following triple immunofluorescence (a-d) staining with Alex-546-Insulin (red), pAkt (green), and NeuN (blue) and double immunofluorescence staining (g-j) with NeuN (green) and Cl-Caspase-3 (red) of the ipsilateral hippocampal CA3 region at the dorsal hippocampal level at P11 following HI/Sham and immediate InInsulin/Veh treatment at P10 are shown, Scale bar = 100 μm. Quantification of pAkt and Cl-Caspase-3 positive cells in left (e, k) and right (f, l) hippocampal CA3 region at the dorsal hippocampal level, respectively are presented as box and whisker graphs. Two-way ANOVA followed by Post-hoc Holm-Sidak test, male and female pups were examined separately by the Kruskal-Wallis One Way Analysis of Variance on Ranks, followed by Post-hoc Student-Newman-Keuls test (for equal group sizes) or Dunn test (for equal group sizes), n = 4 pups/sex/group. Data are presented as median and range by the box and whisker plot. Dotted line represents the mean and symbol • represents outliers.
