Figure Lengend Snippet: Cilengitide targeted therapy for CRC associated with high-fat diet. A .Western blot analysis of AKT, p-AKT, SREBP1, ERK, p-ERK, and CPT1A in HCT116 and HT29 cells treated with recombinant POSTN with or without Cilengitide. Quantification of relative protein levels is shown adjacent to the blot images. B . Intracellular TG and NEFA levels in HCT116 and HT29 cells treated with recombinant POSTN with or without Cilengitide. C . Representative fluorescence microscopy images of neutral lipid accumulation (green, BODIPY staining) in HCT116 and HT29 cells treated with recombinant POSTN with or without Cilengitide. Nuclei are counterstained with DAPI (blue). Scale bars, 50 µm. D .The volumes of subcutaneous transplanted tumors from the control group, LY294002 group, PD98059 group, Cilengitide group and Cilengitide+LY294002+PD98059 group. E . Representative images of subcutaneous transplanted tumors from control group (n = 5), LY294002 group (n = 5), PD98059 group (n = 5), Cilengitide group (n = 5), and Cilengitide+LY294002+PD98059 group (n = 5). F . The size and weights of subcutaneous transplanted tumors from the control group, LY294002 group, PD98059 group, Cilengitide group, and Cilengitide+LY294002+PD98059 group. G . Representative HE and IHC images of Ki-67 and α-SMA of subcutaneous transplanted tumors from the control group, LY294002 group, PD98059 group, Cilengitide group, and Cilengitide+LY294002+PD98059 group. Scale bars, 50 µm. H .Western blot analysis of AKT, p-AKT, SREBP1, ERK, p-ERK, and CPT1A of subcutaneous transplanted tumors from the control group, LY294002 group, PD98059 group, Cilengitide group, and Cilengitide+LY294002+PD98059 group. Quantification of relative protein levels is shown adjacent to the blot images.The data are means ± SD, for all panels: * P < 0.05; ** P < 0.01
Article Snippet: The recombinant protein POSTN (100 ng/mL, 10299-H08H, Sinobiological), AKT inhibitor LY294002 (20 μM, L832989-10 mg, Macklin), ERK inhibitor PD98059 (10μM, P832941-5 mg, Macklin), Cilengitide (10 μM, BD628662, Bidepharm) was applied to HCT116 and HT29 cells for 24 h. MC38 cells were treated with CM.
