Figure Lengend Snippet: A) Volcano plot of genes up- or down-regulated in KIAA1429 knockdown vs NTG control neurons. Glycolytic genes are more strongly affected than mitochondrial complex I assembly genes. Data compiled from n = 2 samples per condition. B) Plot of transcripts’ abundance in KIAA1429 KD cells and NTG control cells after 4-hour exposure to transcription inhibitor actinomycin relative to before exposure. Knockdown in KIAA1429 was associated with decreased abundance of SOX2 and NGF-related transcription targets (dark blue) after treatment with actinomycin. The expression of these transcripts was not significantly decreased in neuronal cells expressing a non-targeting guide, also subjected to treatment with actinomycin, indicating that KIAA1429 activity has a stabilizing effect on these transcripts. In contrast, glycolytic transcripts (red) significantly increased expression in neuronal cells with KIAA1429 knockdown and actinomycin treatment, indicating that stability of these transcripts was not impacted by KIAA1429 expression. Data compiled from n = 2 samples per condition. All “hit” genes have adjusted p-values < 0.05.

doi: 10.64898/2025.12.19.695350

Figure Lengend Snippet: A) Heatmap of the cluster of genes enriched for dendrite membrane components from includes MAPT , KIAA1429, and TDRD3 . Knockdown of these genes results in a common phenotype of poor survival in the high-oxygen glycolytic state (20G), while retaining survival in the high oxygen respiratory state (20R). B) Proposed mechanism by which knocking down genes that support various steps in late glycolysis results in diversion of glucose to upstream glycolytic branch metabolites, including nucleotides. C) Bubble plot of enriched metabolic pathways among metabolites with increased or decreased 13C-glucose derived labeling in neurons with genetic knockdowns. Bubble radius corresponds to pathway impact, which is a measure of the centrality of enriched metabolites. In the high-oxygen glycolytic state, knockdown of these three functionally similar genes in neuronal cells was associated with increased 13C-glucose-derived labeling across purine metabolites, compared to neuronal cells expressing a non-targeting sgRNA. In contrast, knockdown of GLO1 , a gene less related gene by hierarchical clustering, did not increase 13C-glucose-derived labeling in purine metabolites. D) UDP, AMP, and ADP metabolites specifically are significantly increased 13C-glucose-derived labeling associated with knockdown in MAPT , KIAA1429 , and TDRD3 but not GLO1 in the high-oxygen glycolytic state. E) TCA cycle metabolites are among the metabolites that have less 13C-glucose-derived labeling in the high-oxygen glycolytic state.
