Article Title: Loss of NgBR causes neuronal damage through decreasing KAT7-mediated RFX1 acetylation and FGF1 expression

doi: 10.1007/s00018-025-05660-6

Figure Lengend Snippet: NgBR deficiency leads to the downregulation of FGF1 expression and secretion. A Expression clustering heatmap analysis of differentially expressed genes related to the PI3K-AKT pathway shown in Fig. B. B‒D SH-SY5Y cells were transfected with the indicated siRNAs for 48 h. Then, the samples were subjected to qRT‒PCR ( B ) or immunoblotting ( C ). The relative protein level of FGF1 to that of β-actin in ( C ) was analyzed as shown in D. n = 3, * P < 0.05, ** P < 0.01, *** P < 0.001. E SH-SY5Y cells were transfected with Flag or Flag-NgBR for 48 h, after which the cell lysates were subjected to immunoblot analysis. F The protein levels of FGF1 relative to those of β-actin in ( E ) were analyzed. n = 3, ** P < 0.01. G N2a cells were transfected with the indicated siRNAs for 48 h. Then, the cell lysates were subjected to immunoblot analysis. H The protein level of FGF1 relative to that of β-actin in ( G ) was analyzed. n = 3, * P < 0.05, ** P < 0.01. I MES23.5 cells were transfected with the indicated siRNAs for 48 h. Then, the cell lysates were subjected to immunoblot analysis. J The protein level of FGF1 relative to that of β-actin in ( I ) was analyzed. n = 3, * P < 0.05. K Nus1 flox/flox primary cortical neurons were infected with LV-Ctrl or LV-Cre and cultured for 6 days. Then, the cell lysates were subjected to immunoblot analysis. L The protein level of FGF1 relative to that of β-actin in ( K ) was analyzed. n = 3, ** P < 0.01. M-N SH-SY5Y cells were transfected with the indicated siRNAs for 24 h. Then, the cells were cultured with serum-free medium for 24 h, and the FGF1 content in the culture medium ( M ) and cell lysate ( N ) was detected via an ELISA kit. n = 3, * P < 0.05, ** P < 0.01, *** P < 0.001

Article Snippet: SH-SY5Y cells were inoculated into 24-well plates and treated with siRNAs against NUS1 for 24 h. Then, the cells were cultured with serum-free medium for 24 h, and 100 μL of the FGF1 content in the culture medium or in cell lysate was measured with an ELISA kit (EK0339, BOSTER, Wuhan, China).
