Salvigenin Suppresses Hepatocellular Carcinoma Glycolysis and Chemoresistance Through Inactivating the PI3K/AKT/GSK-3β Pathway.

ABSTRACT: Salvigenin is a Trimethoxylated Flavone enriched in Scutellariae Barbatae Herba and Scutellariae Radix and is demonstrated to have anti-tumor properties in colon cancer. Notwithstanding, the function and mechanism of Salvigenin in hepatocellular carcinoma (HCC) are less well studied. Different doses of Salvigenin were taken to treat HCC cells. Cell viability, colony formation ability, cell migration, invasion, apoptosis, glucose uptake, and lactate production levels were detected. As shown by the data, Salvigenin concentration dependently dampened HCC cell proliferation, migration, and invasion, weakened glycolysis by abating glucose uptake and lactate generation, and suppressed the profiles of glycolytic enzymes. Moreover, Salvigenin strengthened HCC cells' sensitivity to 5-fluorouracil (5-FU) and attenuated HCC 5-FU-resistant cells' resistance to 5-FU. Through network pharmacological analysis, we found Salvigenin potentially regulates PI3K/AKT pathway. As shown by the data, Salvigenin repressed the phosphorylated levels of PI3K, AKT, and GSK-3β. The PI3K activator 740Y-P induced PI3K/AKT/GSK-3β pathway activation and promotive effects in HCC cells. However, Salvigenin substantially weakened 740Y-P-mediated effects. In-vivo assay revealed that Salvigenin hampered the growth and promoted apoptosis of HCC cells in nude mice. Collectively, Salvigenin impedes the aerobic glycolysis and 5-FU chemoresistance of HCC cells by dampening the PI3K/AKT/GSK-3β pathway.

Project description:BackgroundHepatocellular carcinoma (HCC) is one of the most prevalent malignancies worldwide because of rapid progression and high incidence of metastasis or recurrence. Accumulating evidence shows that CD58-expressing tumor cell is implicated in development of various cancers. The present study aimed to reveal the functional significance of CD58 in HCC progression and the underlying mechanisms.MethodsImmunohistochemical staining (IHC), and western blotting were used to detect the expression of CD58 in HCC tissues and cells. The levels of sCD58 (a soluble form of CD58) in the cell supernatants and serum were assessed by ELISA. CCK-8, colony formation, and xenograft assays were used to detect the function of CD58 on proliferation in vitro and in vivo. Transwell assay and sphere formation assay were performed to evaluate the effect of CD58 and sCD58 on metastasis and self-renewal ability of HCC cells. Western blotting, immunofluorescence (IF), TOP/FOP Flash reporter assay, and subcellular fractionation assay were conducted to investigate the molecular regulation between CD58/sCD58 and AKT/GSK-3β/β-catenin axis in HCC cells.ResultsCD58 was significantly upregulated in HCC tissues. Elevation of CD58 expression correlated with more satellite foci and vascular invasion, and poorer tumor-free and overall survival in HCC patients. Higher sCD58 levels were in HCC patients' serum compared to healthy individuals. Functionally, CD58 promotes the proliferation of HCC cells in vitro and in vivo. Meanwhile, CD58 and sCD58 induce metastasis, self-renewal and pluripotency in HCC cells in vitro. Mechanistically, CD58 activates the AKT/GSK-3β/β-catenin signaling pathway by increasing phosphorylation of AKT or GSK3β signaling, promoting expression of Wnt/β-catenin target proteins and TCF/LEF-mediated transcriptional activity. Furthermore, AKT activator SC-79 or inhibitor LY294002 abolished the inhibitory effect of CD58 silencing on the proliferation, metastasis, and stemness of HCC cells.ConclusionsTaken together, CD58 promotes HCC progression and metastasis via activating the AKT/GSK-3β/β-catenin pathway, suggesting that CD58 is a novel prognostic biomarker and therapeutic target for HCC.
