Figure Lengend Snippet: Villi-crypt in vitro model. Resazurin reduction assay performed (a) over the Villi-(F)-Crypt and Villi-(R)-Crypt scaffolds in the presence and absence of gelatin to aid cell attachment ( n = 3 scaffolds for each condition). (b) Resazurin reduction assay performed for long-term cultures in the absence of gelatin (two independent experiments, n = 5 scaffolds for each condition of each experiment). Data are expressed as mean ± standard deviation. ∗p < 0.05; ∗∗p < 0.01; ∗∗∗p < 0.001. (c) Phalloidin (green) and DAPI (blue) fluorescence microscopy of Caco-2 cells grown for 21 days on the two compositions tested at two different magnifications. (c i ) Top and (c ii ) section view of the scaffolds. Scale bars represent 500 μm and 100 μm. Objectives are 4 × and 10 × , respectively. (d) Confocal images of Villi-(R)-Crypt scaffold cultured with the Caco-2 cells. (d i ) Schematic of the different confocal planes acquired. (d ii ) and (d iii ) details at two different magnifications of villi sections, scaffold baselines and crypt base; displaying the homogeneous covering of the scaffold and junctions formed between cells ( V = villi, C = crypt). Scale bars represent 200 μm (d ii , 10 × objective) and 50 μm (d iii , 20 × objective).

Figure Lengend Snippet: Venn diagram showing the distribution of proteins identified in Villi-(F)-Crypt and Villi-(R)-Crypt scaffolds cultured with Caco-2 cells for the period of 14 and 21 days. The core proteins are shared across all conditions, while the exclusive proteins represent those uniquely identified in specific conditions. The 10 most abundant proteins are highlighted.

Article Title: THOC3 interacts with epithelial-to-mesenchymal transition to promote non-small cell lung cancer carcinoma progression through STAT3 signaling pathway

doi: 10.1016/j.tranon.2026.102741

Figure Lengend Snippet: THOC3 expression is upregulated in LC and is associated with unfavorable prognoses. (A, B) The mRNA expression of THOC3 in LUAD and LUSC tissues, as well as normal lung tissues, was obtained from the GEPIA database. (C) Real-time PCR analysis of THOC3 mRNA expression in cancerous and adjacent non-cancerous tissues from LC patients. (D) Western blot analysis of THOC3 protein levels in cancerous and adjacent tissues from LC patients. (E) Real-time PCR analysis of THOC3 mRNA expression in LC cell lines (H1975, A549, H1299, and PC9) and the normal bronchial epithelial cell line BEAS-2B (F) Western blot analysis of THOC3 protein expression in LC cell lines (H1975, A549, H1299, and PC9) and BEAS-2B cells. (G) Real-time PCR analysis of THOC3 mRNA expression in normal lung tissues and LC samples from different clinical grades. (H) Western blot analysis of THOC3 protein levels in normal lung tissues and LC samples from various clinical stages. (I, J, K) Kaplan-Meier survival curves illustrating the overall survival (OS) of LC patients with high or low THOC3 expression from the TCGA database. (L) Kaplan-Meier survival curves depicting disease-free survival (DFS) in high vs. low THOC3-expressing LC patients from the TCGA database. Each experiment was performed in triplicate. Data are expressed as mean ± SEM; * P < 0.05.
