Figure Legend Snippet: Secretion of therapeutic proteins with a-BLAST and d-BLAST. (a) The human preproinsulin (preproINS) construct contains a signal peptide, B-chain (yellow), C-peptide (dark gray), and A-chain (yellow), with engineered Furin cleavage sites flanking the C-peptide for maturation. To facilitate efficient processing within the Golgi apparatus, Furin protease was co-transfected with the BLAST modules. (b) Kinetic profiling of light-induced insulin secretion. Summary graphs of secreted C-peptide levels, quantified by ELISA, as a proxy for insulin secretion from a-BLAST (left) and d-BLAST (right). Both systems exhibited significant, time-dependent insulin release starting from 2 h of illumination (8.2-fold for a-BLAST, 8.4-fold for d-BLAST), reaching maximal induction at 24 h (13.8-fold for a-BLAST, 19.3-fold for d-BLAST). (c) Plasmid configurations for IL-12 secretion. Schematic of the heterodimeric cytokine IL-12-a-BLAST (left) and d-BLAST-IL-12 (right) constructs. (d) Kinetic profiling of light-induced IL-12 secretion. Summary graphs showing IL-12 secretion levels measured by ELISA. Significant secretion was observed starting at 3 h for a-BLAST (2.5-fold) and 2 h for d-BLAST (2.2-fold). At the 24 h time point, d-BLAST (4.7-fold) demonstrated a slightly higher dynamic range compared to a-BLAST (4.5-fold). Open circles represent individual measurements from three biologically independent samples. Data are presented as means ± S.D. Statistical significance was assessed using one-way ANOVA followed by Tukey’s multiple comparisons test (ns = not significant, * P < 0.05, ** P < 0.01, *** P < 0.001, **** P < 0.0001).
Techniques Used: Construct, Transfection, Enzyme-linked Immunosorbent Assay, Plasmid Preparation
