摘要
BACKGROUND: Intrahepatic cholangiocarcinoma (ICC) ranks second among primary liver cancers in terms of prevalence, characterized by poor prognosis and scarce therapeutic interventions. Fufang-Biejia-Ruangan tablet (BJRG), a traditional Chinese herbal remedy, has been widely used for liver diseases. However, its therapeutic efficacy and underlying mechanisms in ICC remain poorly understood. AIM OF THE STUDY: This study aims to systematically investigate the anti-ICC effects of BJRG, focusing on tumor progression and microenvironment modulation, through experimental and transcriptomic analyses. METHODS: The chemical composition of BJRG was analyzed employing ultra-performance liquid chromatography-mass spectrometry (UPLC-MS). In vitro assays were performed with QBC939 and LX-2 cell lines. Two primary ICC models (AKT/YAP and sgP53/KRAS) were established via hydrodynamic tail-vein injection of corresponding plasmids. A co-culture system for subcutaneous tumor formation was developed using cancer-associated fibroblasts (CAFs) derived from the AKT/YAP model and primary tumor cells derived from the sgP53/KRAS model. RESULTS: UPLC-MS analysis identified 1091 chemical components, primarily terpenoids, sugars, glycosides, and phenylpropanoids. The therapeutic efficacy of BJRG was evaluated for the treatment of ICC. BJRG treatment slowed down the growth of both human ICC cell lines and AKT/YAP ICC mouse model. Mechanistically, BJRG inhibited HIPPO-PI3K/AKT signaling pathway in ICC tumor cells. Importantly, BJRG significantly inhibited the growth of CAFs via HIPPO-PI3K/AKT cascades. Of note, co-culture CAFs with ICC cell lines substantially sensitized the efficacy of BJRG in sgP53/KRAS syngeneic tumor model. Furthermore, BJRG therapy not only affected CAFs but also induced alterations in vascular structures and hypoxic conditions within lesions in the AKT/YAP model. This intervention promoted the infiltration of T lymphocytes and macrophages into the tumor microenvironment, which may further augment the anti-proliferative effects of BJRG by enhancing the immune response within ICC tumor tissues. CONCLUSION: Our research demonstrates BJRG's anti-ICC efficacy via diverse pathways, including the suppression of tumor cell proliferation, regulation of CAFs activity, and promotion of immune cell infiltration. These findings underscore BJRG as a promising therapeutic candidate for ICC, offering novel mechanistic insights and highlighting its potential for clinical translation.
