    MedChemExpress mtor activator mhy1485
    (A) Experimental timeline showing intravitreal injections of vehicle (1% DMSO), insulin + rapamycin (0.2 mg/mL and 20 µM, respectively), or <t>MHY1485</t> (100 µM) at 2, 3, and 4 days post-injury (dpi). Dendritic morphology and optic tectum reinnervation are quantified at 6 dpi. (B) Schematic of the insulin signaling pathway and pharmacological manipulations. Insulin activates mTORC2 and, via Akt signaling, mTORC1. Rapamycin selectively inhibits mTORC1, while MHY1485 selectively activates it. Green arrows indicate activation, and red blunt-ended lines indicate inhibition. (C) Representative sagittal retinal cryosections stained for phospho-S6 (pS6, Ser235/Ser236) and DAPI show comparable S6 phosphorylation in MHY1485-treated and vehicle-treated retinas at 3 dpi. Combined insulin and rapamycin treatment sharply reduces S6 phosphorylation in the retina. Scale bar = 25 µm. (D) Quantification of pS6–positive cells in the ganglion cell layer (GCL) shows a comparable percentage of pS6-positive cells in MHY1485-treated and vehicle-treated retinas, whereas combined insulin and rapamycin treatment results in almost no pS6-positive cells in the GCL. (E) Representative dendritic reconstructions at 6 dpi of cells from retinas treated with vehicle, combined insulin and rapamycin, or MHY1485. Combined insulin and rapamycin treatment results in dendritic complexity comparable to vehicle controls, whereas MHY1485-treated RGCs show increased dendritic complexity relative to vehicle-treated cells. Scale bar = 100 µm. (F) Quantification of dendritic morphometrics (Sholl AUC, dendritic area, total dendritic length, and number of bifurcations) reveals that MHY1485 increases dendritic complexity relative to vehicle, whereas insulin + rapamycin does not significantly alter dendritic complexity compared with vehicle. (G) Representative coronal optic tectum sections following anterograde biocytin tracing. Biocytin visualization shows decreased tectal reinnervation after both combined insulin and rapamycin treatment or MHY1485 treatment compared with vehicle controls at 6 dpi. Scale bar = 200 µm. (H) Quantification of biocytin-positive area in the optic tectum disclose that both insulin plus rapamycin and MHY1485 treatments delay tectal reinnervation relative to vehicle. Data presented as median ± 95% confidence interval (D) or mean ± SD (F). Each dot represents one cell (D; N=52-63 cells sampled from n = 7 fish per group) or one fish (D; n = 4-5) (F; n = 7). One-way Kruskal-Wallis ANOVA with Tukey HSD post hoc tests (D, H) or one-way Welch ANOVA with Games–Howell multiple-comparisons test (F); exact p values are shown in the figure.

Insulin activates mTORC2 and, via Akt signaling, mTORC1. Rapamycin selectively inhibits mTORC1, while MHY1485 selectively activates it. Green arrows indicate activation, and red blunt-ended lines indicate inhibition. (C) Representative sagittal retinal cryosections stained for phospho-S6 (pS6, Ser235/Ser236) and DAPI show comparable S6 phosphorylation in MHY1485-treated and vehicle-treated retinas at 3 dpi. Combined insulin and rapamycin treatment sharply reduces S6 phosphorylation in the retina. Scale bar = 25 µm. (D) Quantification of pS6–positive cells in the ganglion cell layer (GCL) shows a comparable percentage of pS6-positive cells in MHY1485-treated and vehicle-treated retinas, whereas combined insulin and rapamycin treatment results in almost no pS6-positive cells in the GCL. (E) Representative dendritic reconstructions at 6 dpi of cells from retinas treated with vehicle, combined insulin and rapamycin, or MHY1485. Combined insulin and rapamycin treatment results in dendritic complexity comparable to vehicle controls, whereas MHY1485-treated RGCs show increased dendritic complexity relative to vehicle-treated cells. Scale bar = 100 µm. (F) Quantification of dendritic morphometrics (Sholl AUC, dendritic area, total dendritic length, and number of bifurcations) reveals that MHY1485 increases dendritic complexity relative to vehicle, whereas insulin + rapamycin does not significantly alter dendritic complexity compared with vehicle. (G) Representative coronal optic tectum sections following anterograde biocytin tracing. Biocytin visualization shows decreased tectal reinnervation after both combined insulin and rapamycin treatment or MHY1485 treatment compared with vehicle controls at 6 dpi. Scale bar = 200 µm. (H) Quantification of biocytin-positive area in the optic tectum disclose that both insulin plus rapamycin and MHY1485 treatments delay tectal reinnervation relative to vehicle. Data presented as median ± 95% confidence interval (D) or mean ± SD (F). Each dot represents one cell (D; N=52-63 cells sampled from n = 7 fish per group) or one fish (D; n = 4-5) (F; n = 7). One-way Kruskal-Wallis ANOVA with Tukey HSD post hoc tests (D, H) or one-way Welch ANOVA with Games–Howell multiple-comparisons test (F); exact p values are shown in the figure.
