Article Title: Loperamide reverses 5-FU resistance in colorectal cancer by activating autophagy
doi: 10.3892/or.2025.8966
Figure Lengend Snippet: LOP enhances the inhibitory effects of 5-FU on HCT8R cells through autophagy activation. (A) Western blot analysis of changes in LC3 and Beclin protein expression in HCT8R cells treated with LOP and 5-FU. (B) Confocal microscopy images, showing the generation of autophagic vesicles in HCT8R cells transfected with the EGFP-LC3 plasmid, and treated with LOP and 5-FU. (C) Western blot analysis of Beclin protein expression in HCT8R cells treated with or without 3-MA. (D) Statistical analysis of changes in Beclin expression in HCT8R cells treated with or without 3-MA. (E) Transwell assays were performed, assessing the migratory capability of HCT8R cells treated with LOP, 5-FU, with or without 3-MA. *P<0.05, **P<0.01 (n=3). 3-MA, 3-methyladenine; 5-FU, 5-fluorouracil; DMSO, dimethyl sulfoxide; LC3, microtubule-associated protein 1 light chain 3; LOP, loperamide; ns, not significant.
Article Snippet: Transfection was subsequently performed using Lipo8000 TM reagent (Beyotime Institute of Biotechnology) in combination with 2 μg pEGFP (cat. no. 165830; Addgene, Inc.) or pEGFP-microtubule-associated protein 1 light chain 3 (LC3) plasmid (cat. no. 24920; Addgene, Inc.) and Opti-MEM TM serum-free medium (Gibco; Thermo Fisher Scientific Inc.).
