Figure Lengend Snippet: AAV transduced CD44-positive cell populations with greater efficiency (A) Transduction efficiency of AAV1, 2, 1/2, 6, and 6.2 in CD44-positive and -negative cell populations. Two-way ANOVA showed no significant interaction between the effects of AAV serotype and CD44 expression on transduction efficiency in all cell lines. There was a significant main effect of CD44 expression in U-87 MG ( p = 0.007), case 1 ( p = 0.0003), and case 4 ( p = 0.010) but no statistical significance was found following Sidak’s multiple comparisons test. (B) CD44 expression in human GBM cell lines following AAV treatment. (C) Proliferation of the CD44-positive cell population normalized to values from NTC-treated control. Treatments were compared against their respective pBS-treated control. All data presented as mean (SD), n = 3 biological replicates. Statistical significance is shown as ∗ p < 0.05, ∗∗ p < 0.01, ∗∗∗ p < 0.001, ∗∗∗∗ p < 0.0001.

Figure Lengend Snippet: AAV treatment induced cell-cycle arrest at G1 in cases 2 and 5 but not U-87 MG (A) Cumulative cytotoxicity was evaluated by LDH release assay 4 days following AAV treatment, normalized to the maximal LDH release from the Triton X-100 control. No statistical significance was detected. (B) Percentage of cells in each cell cycle phase (G0/G1, S, and G2/M) were quantified via DNA content profiling (see also ). All data presented as mean (SD), n = 3 biological replicates. Treatments were compared against their respective pBS-treated control. Statistical significance is shown as G0/G1 phases: ∗∗∗∗ p < 0.0001; S phase: † p < 0.05; G2/M phases: # p < 0.05, ### p < 0.001.

Figure Lengend Snippet: a Schematic of the synthesis and immobilization strategy for biotinylated CA4-prodrug ( 6 ), synthesized via sequential decoration of cTCO-bis-NHS ( 5 ). The biotin handle allows immobilization onto streptavidin-coated magnetic beads, forming a localized, iontronically activatable prodrug reservoir. IPs were positioned above the beads in a transwell insert containing U-87 cells in the lower chamber. Grey pills indicate inactive (bound) drug, blue (colored) pills indicate active drug. b 3D-printed platform designed to precisely position iontronic devices in standard 96-well transwell plates. c Cell viability of U-87 cells after operating iontronic devices delivering 1 for 4 h at +20 nA (Active, n = 8) and at −20 nA (Reverse, n = 7) into transwells holding CA4-immobilized beads from ( a ). Points represent individual biological replicates; bars indicate mean ± SD. GC growth control (untreated, n = 32), “No Beads” = operation of iontronic devices delivering 1 at +20 nA, no beads in transwell present ( n = 6), “No Tz 1 ” = CA4-immobilized beads in transwell present with iontronic delivery of K + (0.1 M KCl) instead of Tz 1 ( n = 8). Statistical analysis was done via a Brown–Forsythe and Welch ANOVA tests (one-way) and Dunnett’s T3 multiple comparisons test. α = 0.05. p -values: GC vs. No Beads (ns) = 0.2377; GC vs. No Tz 1 (ns) = 0.3827; GC vs. Reverse, 4 h (ns) = 0.5739, GC vs. Active, 4 h (****) = <0.0001.
