doi: 10.3892/ijo.2024.5691
Figure Lengend Snippet: Emodin inhibits the survival of upper urinary tract urothelial carcinoma Cells by inhibiting PKA signaling. The cells were divided into four groups. Con group, cells were treated with 10 nM BZ alone for 48 h; Emodin group, cells were pretreated with 50 μ M emodin for 1 h, followed by the addition of 10 nM BZ for 48 h; Sp-8-CPT-cAMPS group, cells were pretreated with 10 μ M Sp-8-CPT-cAMPS for 1 h, followed by the addition of 10 nM BZ for 48 h; and Emodin + Sp-8-CPT-cAMPS group, cells were pretreated with a combination of 10 μ M Sp-8-CPT-cAMPS and 50 μ M emodin for 1 h, followed by the addition of 10 nM BZ for 48 h. Western blotting analysis showing the PKA and COX2 expression levels in (A) BFTC909 and (B) UM-UC-14 cells treated as aforementioned. The PGE2 levels in (C) BFTC909 and (D) UM-UC-14 cells treated as aforementioned. Cell Counting Kit-8 assays indicating the viability of (E) BFTC909 and (F) UM-UC-14 cells treated as aforementioned. * P<0.05, ** P<0.01, *** P<0.001 vs. Con; # P<0.05, ## P<0.01, ### P<0.001 vs. emodin. BZ, benzidine; Con, control; COX2, cyclooxygenase 2; PGE2, prostaglandin E2; PKA, protein kinase A.
Article Snippet: The cells were divided into four groups for treatment: i) Control (Con) group, cells were treated with 10 nM BZ alone for 48 h; ii) emodin group, cells were pretreated with 50 μ M emodin for 1 h, followed by the addition of 10 nM BZ for 48 h; iii) Sp-8-CPT-cAMPS group, cells were pretreated with 10 μ M Sp-8-CPT-cAMPS (cat. no. HY-120994B; MedChemExpress) for 1 h, followed by the addition of 10 nM BZ for 48 h; and iv) emodin + Sp-8-CPT-cAMPS group, cells were pretreated with a combination of 10 μ M Sp-8-CPT-cAMPS and 50 μ M emodin for 1 h, followed by the addition of 10 nM BZ for 48 h. Then, the cells were collected for further assay.
