doi: 10.1002/cbf.70318

Figure Lengend Snippet: Predicted binding of let‐7c‐5p to ZBP1 mRNA and the effects of let‐7c‐5p overexpression on ZBP1 expression and PANoptosis‐related protein levels in SH‐SY5Y cells. (A) Bioinformatic prediction showing two potential binding sites of let‐7c‐5p in ZBP1 mRNA, located within the 3' UTR and 5' UTR. The predicted binding entropy values were 25.2 and 24.5 kcal/mol, respectively, suggesting direct regulation by let‐7c‐5p; (B) GFP fluorescence image of SH‐SY5Y cells 48 h after lentiviral transduction of let‐7c‐5p. RT‐qPCR analysis showing efficient overexpression of let‐7c‐5p; (C) RT‐qPCR analysis of ZBP1 mRNA expression and western blot analysis of ZBP1 protein levels; (D) Western blot analysis of PANoptosis‐related proteins, including Caspase‐3, GSDMD, GSDME, and MLKL. * p < 0.05 versus Blank and C groups. n = 3.

Article Title: Simultaneous activation and release of a microtubule inhibitor from amphiphilic polymeric nanoparticles

doi: 10.1039/d6na00763e

Figure Lengend Snippet: Cell viability following treatment with free proPST-1 under dark and irradiated conditions at different concentrations. In the absence of irradiation, proPST-1 shows minimal cytotoxicity, whereas 365 nm irradiation induces a pronounced concentration-dependent decrease in cell viability, consistent with photolytic uncaging and activation of PST-1 in (a) HeLa cells, (b) SH-SY5Y cells. Cell viability following treatment with proPST-1-loaded polymer nanoparticles (proPST-1@PN) under dark and irradiated conditions. Encapsulated proPST-1@PN remains non-toxic in the dark, while irradiation results in strong concentration-dependent cytotoxicity, confirming light-triggered activation and release of cis -PST-1 from the nanoparticle core in (c) HeLa cells, (d) SH-SY5Y cells. Cell viability was determined using the CCK-8 assay after treatment under the indicated conditions. Data are presented as mean ± SD. ** P < 0.01, *** P < 0.001, **** P < 0.0001, and ns is not significant, assessed by two-way ANOVA followed by Šídák's multiple comparison test. In all cases, the concentration on the X axis refers to the (pro)PST-1 concentration.
