    Article Title: Postoperative exosomal miR-1246 fuels hepatocellular carcinoma metastasis via BMP9-SMAD7 axis suppression.
    Article Snippet: Emerging evidence highlights the perioperative period, particularly the immediate postoperative window of days to weeks, as a critical phase influencing long-term cancer outcomes.. Here, we found that hepatocellular carcinoma (HCC) cells cultured with postoperative serum exhibited enhanced anoikis resistance, invasion, migration, and increased potential for lung metastasis compared to those cultured with preoperative serum.. This prometastatic effect was attributed to serum-derived exosomes.

    Effects of silencing the AQP1 gene and exogenous administration of <t>BMP9</t> on AQP1 and BMP/TGF‐β signaling molecules in human pulmonary microvascular endothelial cells. HPMECs were silenced for the AQP1 gene and the relative mRNA and protein expression of AQP1 (A, B), BMPR2 (C, D), TGFBR1 (E, F), and TGFB1 (G, H) were estimated before and after the exogenous administration of BMP9. Relative mRNA expression is shown in dot plots (dots, individual values; line in the middle, median values; lower and upper lines, 25th and 75th percentiles) (A, n = 6; C, n = 7; E, n = 7; G, n = 6). Protein expression was analyzed by SDS‐PAGE and immunoblotting, and relative expression was estimated by densitometry using β‐tubulin as a loading control. Relative protein expression is shown with bar plots (mean ± SEM; dots, individual values) (B, n = 4; D, n = 4; F, n = 4; H, n = 4). Representative expression of AQP1 (B), BMPR2 (D), TGFBR1 (F), and TGFB1 (H) (upper panels) and β‐tubulin (lower panels) proteins in the AQP1 ‐silenced HPMEC homogenates. Specificity (siRNA negative control), efficiency ( AQP1 siRNA), and the effect of BMP9 exogenous administration on the non‐transfected controls were tested each time to ensure the consistency and reproducibility across the independent experiments. Statistical analysis was performed using the Mann–Whitney test. *, p < 0.05; **, p < 0.01 compared to the non‐transfected control HPMECs.

    Effects of silencing the AQP1 gene and exogenous administration of BMP9 on AQP1 and BMP/TGF‐β signaling molecules in human pulmonary microvascular endothelial cells. HPMECs were silenced for the AQP1 gene and the relative mRNA and protein expression of AQP1 (A, B), BMPR2 (C, D), TGFBR1 (E, F), and TGFB1 (G, H) were estimated before and after the exogenous administration of BMP9. Relative mRNA expression is shown in dot plots (dots, individual values; line in the middle, median values; lower and upper lines, 25th and 75th percentiles) (A, n = 6; C, n = 7; E, n = 7; G, n = 6). Protein expression was analyzed by SDS‐PAGE and immunoblotting, and relative expression was estimated by densitometry using β‐tubulin as a loading control. Relative protein expression is shown with bar plots (mean ± SEM; dots, individual values) (B, n = 4; D, n = 4; F, n = 4; H, n = 4). Representative expression of AQP1 (B), BMPR2 (D), TGFBR1 (F), and TGFB1 (H) (upper panels) and β‐tubulin (lower panels) proteins in the AQP1 ‐silenced HPMEC homogenates. Specificity (siRNA negative control), efficiency ( AQP1 siRNA), and the effect of BMP9 exogenous administration on the non‐transfected controls were tested each time to ensure the consistency and reproducibility across the independent experiments. Statistical analysis was performed using the Mann–Whitney test. *, p < 0.05; **, p < 0.01 compared to the non‐transfected control HPMECs.
