SUMO1 knockdown downregulates PI3K/AKT pathway. Immunocytochemistry images showing a decrease in the expression of (a) PI3K (red), (b) pAKT (red), (c) pCREB (red), and (d) BDNF (red) in SUMO1 knockdown cells compared to control. Nuclei are stained blue with DAPI, and microglia are stained green with Lectin. Scale bar = 10 μm. BDNF, brain‐derived neurotrophic factor; CREB, cAMP response element‐binding protein; PI3K, phosphatidylinositol 3‐kinase [Color figure can be viewed at http://wileyonlinelibrary.com]
