Data were represented as mean +- SD. Statistical differences between groups were analyzed using one-way ANOVA, followed by Tukey''s post hoc test (* p < 0.05 versus sham, # p < 0.05 versus 6 h HI, @ p < 0.05 versus 24 h HI, & p < 0.05 versus 48 h HI; n = 4 per group). e Representative microphotographs of double immunofluorescence of alpha-MSH (green) with microglia (Iba-1, red), astrocyte (GFAP, red), and neuron (NeuN, red) in the peri-infarcted area at 24 h post-HI.

- Fig. 8 MC1R activation on neuroinflammation via cAMP/PKA/Nurr1 signaling pathway at 48 h post-HI. a Representative picture of Western blot data showing bands of the expression levels of MC1R, cAMP, p-PKA, Nurr1, IL-1beta, TNFalpha, and IL-6 either with BMS-470539 treatment alone, BMS-470539 + MC1R KO CRISPR, BMS-470539 + Nurr1 KO CRISPR, and BMS-470539 + control CRISPR groups. b - h Western blot data quantification of bands showed that BMS-470539 treatment significantly increased the expression of MC1R, cAMP, p-PKA, and Nurr1 compared to the HI + vehicle group. Knockout of MC1R using CRISPR significantly decreased MC1R, cAMP, p-PKA, and Nurr1 expression levels compared to the HI + BMS-470539 group or HI + BMS-470539 + control CRISPR group. Furthermore, knockout of Nurr1 using CRISPR significantly decreased the levels of Nurr1, but did not affect MC1R, cAMP, and p-PKA expression compared to the corresponding controls. Activation of MC1R with BMS-470539 showed significantly decreased levels of IL-1beta, TNFalpha, and IL-6, while both treatment groups with CRISPR interventions significantly reversed these effects. Data was represented as mean +- SD. The one-way ANOVA was followed by Tukey''s post hoc test (* p < 0.05 versus sham; # p < 0.05 versus HI + vehicle; @ p < 0.05 HI + BMS-470539 or HI + BMS-470539 + control CRISPR; n = 6 per group)

Immunofluorescence staining showed that MC1R (a) and Nurr1 (b) expressions on neurons were seen to be higher in the vehicle-treated pup rats compared to the sham group, and a higher expression of MC1R (a) and Nurr1 (b) on neurons after BMS-470359 treatment compared with vehicle.

- Figure 5 BMS-470539 treatment exerted its antioxidative stress and antiapoptosis effects via MC1R/cAMP/PKA/Nurr1 signaling pathway at 48 h post-HI. (a) Representative Western blot bands. (b-i) Quantification of MC1R, cAMP, p-PKA, Nurr1, 4-HNE, HO-1, Bax, and Bcl-2 expression levels in the ipsilateral hemisphere at 48 h post-HI. BMS-470539 treatment significantly increased the protein levels of MC1R, cAMP, p-PKA, Nurr1, HO-1, and Bcl-2 but significantly decreased the expression of 4-HNE and Bax compared to the HI+vehicle group. Knockout of MC1R or Nurr1 with CRISPR interventions significantly abolished such effects of BMS-470539. n = 6 per group. Data was represented as mean +- SD. * p < 0.05 versus sham, # p < 0.05 versus HI+vehicle, @ p < 0.05 HI+BMS-470539 or HI+BMS-470539+control CRISPR; one-way ANOVA, Tukey's post hoc test.
