Figure Legend Snippet: Figure 5. Nuclear PKM2 activity alters the neuronal epigenetic landscape (A) Schematic: phosphorylated PKM2 translocates to the nucleus to interact with transcription factors to regulate gene expression. (B and C) Immunostaining (B) and quantification (C) of p-PKM2(Ser37) (control, n = 8; AD, n = 5). Scale bars, 10 mm. (D and E) Immunostaining (D) and quantification (E) of phosphorylated histone 3 (T11) of MAP2-positive neurons (control, n = 6; AD, n = 5). Scale bars, 10 mm. (F) ATAC-seq profiles around transcriptional start sites of genes regulated by HIF1a, STAT3, and b-catenin (CTNNB1), based on ReMap2020 (control, n = 11; AD, n = 9). (G) HOMER motif enrichment analysis of AD differentially open peaks for HIF1a and STAT3, as previously published (Mertens et al., 2021). (H and I) Differential expression (H) and GO term enrichment (I) of significant genes regulated by HIF1a or STAT3. (B–H) Violin plots: median and quartiles. Significance: unpaired t test, *p < 0.05, **p < 0.01.
Techniques Used: Activity Assay, Gene Expression, Immunostaining, Control, Quantitative Proteomics
Figure Legend Snippet: Figure 6. A metabolic shift induces AD-like apoptotic competency in human neurons (A and B) Immunostaining (A) and quantification (B) of cleaved caspase-3 over DAPI of bIII-tub-positive control and AD iNs (control, n = 9; AD, n = 7). Scale bars, 50 mm. Green arrows point out Casp3-positive neurons. (C) Schematic: induction of neuronal apoptosis by ABT-737 treatment. (D) Cell death assessed by cleaved caspase 3/bIII-tub-positive cells of control (green) and AD (teal) iNs in response to 0–1 mM ABT-737. (E and F) Immunostaining (E) and quantification (F) of cleaved caspase-3 in bIII-tub neurons after Bcl2 inhibition in control (n = 10) and AD (n = 8) iNs. Scale bars, 50 mm. (G) Pearson correlation analysis of cleaved caspase-3 immunostaining and glycolytic metabolites (UHPLC-MS). (H and I) Control iNs treated with CoDo for 2 days (H) showed increased lactate secretion (vehicle, n = 5; CoDo, n = 5) (I). (J) Quantification of p-PKM2 FI in the nucleus/cytoplasm comparing vehicle-treated (n = 6) and CoDo-treated control iNs (n = 6). (K) Immunostainings of bIII-tub and EGFP fluorescence of EGFP::PKM2 transduced iNs. Dotted lines show cytoplasmic ROI. Scale bars, 100 and 25 mm. (L) Longitudinal EGFP::PKM2 localization in vehicle-treated (n = 3) or CoCl2-treated (n = 4) control iNs. (M and N) Immunostaining (M) and quantification (N) of cleaved caspase-3 positive cells/DAPI before and after ABT-737 (vehicle and CoDo, n = 6; one-way ANOVA, DF: 23, F = 21.34, p < 0.0001, Dunnett’s multiple comparison). Scale bars, 50 mm. Dots represent individual donors throughout the figure. Bars, mean; error bars, SD; significance, unpaired t test, *p < 0.05, **p < 0.01, ***p < 0.001.
Techniques Used: Immunostaining, Positive Control, Control, Inhibition, Comparison
Figure Legend Snippet: Figure 7. PKM2 inhibition ameliorates PKM2-induced apoptotic competency (A) Schematic: shikonin treatment prevents PKM2 nuclear translocation and increases metabolic enzymatic activity. (B) Longitudinal EGFP::PKM2 localization in vehicle-treated (n = 3), CoCl2-treated (n = 4), and CoCl2+shikonin-treated (n = 4) control iNs.
Techniques Used: Inhibition, Translocation Assay, Activity Assay, Control
