Figure Lengend Snippet: The exploration of the potential regulatory mechanisms of TLN1 in CRPC. (A) RNA sequencing was performed in DU145 cells, comparing the number of protein-coding genes detected between the TLN1 knockdown group and the control group. (B) Volcano plot of differentially expressed genes, illustrating the changes in gene expression between TLN1 knockdown and control groups in DU145 cells. (C) Statistics of differentially expressed genes under TLN1 knockdown versus control conditions in DU145 cells. (D) Heatmap of differentially expressed genes, with color gradient representing gene expression levels—red indicates high expression and green indicates low expression. (E, F) NGFR upregulation at the mRNA and protein levels after TLN1 knockdown was verified by qPCR and Western blot, respectively. (G) Western blot analysis was employed to assess the effects of TLN1 knockdown on apoptosis and the PI3K-AKT, MAPK, and NF-κB signaling pathways in DU145 and PC3 cell lines. (H) Expression profile of NGFR in PCa tissues based on analysis from the GEPIA2 database. (I) Western blot analysis was conducted to assess the expression of TLN1 and NGFR in the normal prostate cell line WPMY-1 and the CRPC cell lines DU145 and PC3. (J) Correlation analysis of TLN1 and NGFR expression in PCa was performed using the GEPIA3 database. (K) Molecular docking simulation results of TLN1 with NGFR. (L) Co-IP assay confirming the protein interaction between TLN1 and NGFR. (M, N) Knockdown efficiency of three NGFR-targeting plasmids was evaluated by qPCR and Western blot, respectively; shCtrl served as the negative control, while shNGFR-1, shNGFR-2, and shNGFR-3 represent NGFR-specific knockdown plasmids. Data were presented as mean with standard deviation. * P < 0.05, ** P < 0.01 and *** P < 0.001.
