Figure Lengend Snippet: Changes in the RT‐PCR gene expression profile of cellular metabolism genes (HIF‐1α, HIF‐1β, and GLUT‐1) following raw BlackSs [HIF‐1α (A), HIF‐1β (B), and GLUT‐1 (C)] and BlackSb [HIF‐1α (D), HIF‐1β (E), and GLUT‐1 (F)] extract treatment on hypoxia‐induced CCD 841 CoN colon cells. Data is presented as mean ± SD ( n = 3). Statistical significance was determined by two‐way ANOVA with Dunnett's post hoc test, adjusting p values for Type I error when comparing multiple treatment groups to a single control. Significance level increases with decreasing p value represented by * p < 0.05, ** p < 0.01, *** p < 0.001, **** p < 0.0001. HIF‐1α, hypoxia inducible factor 1 alpha; HIF‐1β, hypoxia inducible factor 1 beta; GLUT‐1, glucose transporter 1.

Figure Lengend Snippet: Cytotoxic response and intracellular ROS levels induced by the multimodal hydrogel nanoplatform in CRC and normal colon cell models. (A) Dose–response curve of free 5-FU in HCT-116 cells after 48 h, determined by MTT assay and used to define the experimental IC₅₀. Cell viability was normalized to the Ctrl. For visualization on a logarithmic x-axis, the Ctrl condition is plotted at a nominal concentration of 0.1 µg mL⁻¹. (B–D) MTT-based cell viability after 48 h treatment in (B) HCT-116, (C) SW480, and (D) normal human colon epithelial NCM460 cells. Treatment groups include Ctrl, free 5-FU (5FU), non-targeted nanoparticles (NP), HA-targeted nanoparticles (tNP), blank hydrogel (Gel), hydrogel-loaded targeted nanoparticles (Gel-tNP), and Gel-tNP combined with near-infrared irradiation (NIR, 808 nm), X-ray irradiation (XR, 2 Gy), or both. All treatments were administered at an equivalent 5-FU concentration corresponding to the IC₅₀ determined in panel (A). (E) Intracellular ROS levels in HCT-116 cells measured after 48 h using CellROX™ Deep Red and expressed as fold change relative to Ctrl. Data are mean ± SD ( n = 3). Statistical significance was assessed by one-way ANOVA with multiple-comparisons post-hoc testing. Asterisks indicate comparisons vs. Ctrl (* p < 0.05, ** p < 0.01, *** p < 0.001, **** p < 0.0001). Brackets indicate the specific intergroup comparisons shown (e.g., dual-modal vs. tri-modal where indicated). “ns” denotes not significant

Article Snippet: The cytotoxicity of all treatment groups was evaluated using an MTT assay in two CRC cell lines and one normal human colon epithelial cell model. HCT-116 human colorectal carcinoma cells (ATCC ® CCL-247TM, American Type Culture Collection, USA) and SW480 human colorectal adenocarcinoma cells (ATCC ® CCL-228TM, American Type Culture Collection, USA) were used as CRC models, and normal human colon epithelial cells NCM460 (NCM460DTM; INCELL Corporation LLC, San Antonio, TX, USA) were used to provide an initial in-vitro assessment of relative tolerance in non-malignant colon epithelium.
