ABSTRACT
Objective: The aim of this study is to discover the possible working mechanisms of Ardisiae Japonicae Herba (AJH) on hepatoma carcinoma (HCC). Methods: In this study, ethanol extract of AJH was prepared and used to treat HCC cell in vitro. Furthermore, a genomic wide RNA sequencing (RNA-seq) was performed to screen deregulated genes in HCC cells after the treatment of AJH extract. The gene and protein expression related to lipid metabolism in HCC cells were also investigated to validate the results obtained from RNA-seq. Results: AJH extract could inhibit HCC cell proliferation in vitro. RNA-seq analysis has identified 1,601 differentially expressed genes (DEGs, fold change ≥ 2.0 or fold change ≤ 0.5, P < 0.05) in HCC after AJH extract treatment, which included 225 up-regulated genes and 1,376 down-regulated genes. KEGG pathway analysis of DEGs demonstrated that lipid metabolism was a potential pathway related to AJH treatment. In agreement with the RNA-seq data, qPCR and Western-blot analysis indicated that expression of genes and proteins related to lipid metabolism (SREBP1, ACC, ACLY and FASN) were significantly down-regulated in AJH treatment group as compared with the control group. Furthermore, AJH extract could also decrease lipid contents and cellular free fatty acid levels in HCC cells. Conclusion: Ethanol extract of AJH could inhibit HCC cell proliferation in vitro, the possible mechanism may be related to the inhibition of lipid metabolism.
ABSTRACT
Objective :To explore changes of serum levels of galectin-3 and pentraxin-3 (PTX-3) in patients with chro-nic heart failure (CHF) and their correlation with prognosis .Methods : A total of 150 CHF patients (CHF group) treated in our hospital and 150 healthy volunteers undergoing physical examination simultaneously (healthy group ) from Jan 2015 to Dec 2015 were enrolled .Serum levels of galectin-3 ,PTX-3 and N-terminal pro brain natriuretic peptide (NT-proBNP) ,left atrial diameter (LAD) ,left ventricular end-diastolic dimension (LVEDd) and left ven-tricular mass index (LVMI) were compared between two groups at enrollment .According to one-year follow-up out-come ,CHF group (12 cases lost ,another 138 cases) was divided into poor prognosis group (n＝36) and good prog-nosis group (n＝102).Spearman linear correlation analysis was used to analyze correlation among serum galectin-3 , PTX-3 levels and poor prognosis of CHF patients .Results :Compared with healthy group ,there were significant rise in serum levels of galectin-3 [ (2-23 ± 0-25) ng／ml vs .(16-61 ± 1-48) ng／ml] ,PTX-3 [ (1-28 ± 0-54) μg／L vs. (3-58 ± 0-52) μg／L] ,NT-proBNP [(223-23 ± 76-28) pg／ml vs.(952-75 ± 85-43) pg／ml] ,LAD ,LVEDd and LV-MI in CHF group , P＝0-001 all.Compared with good prognosis group at enrollment ,there were significant rise in serum levels of galectin-3 [ (18-52 ± 1-91) ng／ml vs.(24-63 ± 2-26) ng／ml] and PTX-3 [ (2-65 ± 0-74) μg／L vs. (3-95 ± 1-05) μg／L] in poor prognosis group , P＝0-001 both .Spearman linear correlation analysis indicated that serum galectin-3 and PTX-3 levels were significant positively correlated with major adverse cardiovascular events in CHF patients ( r＝0-608 ,0-558 , P＝0-001 both).Conclusion :Serum levels of galectin-3 ,PTX-3 and NT-proBNP levels are significant rise and closely related to prognosis of CHF patients ,can be used as auxiliary indexes predicting prognosis and may provide the basis for formulation of target therapy .
ABSTRACT
The growth inhibitory effects of D-glucosamine hydrochloride (GlcNH(2).HCl), D-glucosamine (GlcNH(2)) and N-acetyl glucosamine (NAG) on human hepatoma SMMC-7721 cells in vitro were investigated. The results showed that GlcNH(2).HCl and GlcNH(2) resulted in a concentration-dependent reduction in hepatoma cell growth as measured by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay. This effect was accompanied by a marked increase in the proportion of S cells as analyzed by flow cytometry. In addition, human hepatoma SMMC-7721 cells treated with GlcNH(2).HCl resulted in the induction of apoptosis as assayed qualitatively by agarose gel electrophoresis. NAG could not inhibit the proliferation of SMMC-7721 cells. GlcNH(2).HCl exhibited antitumor activity against Sarcoma 180 in Kunming mice at dosage of 125-500 mg/kg, dose of 250 mg/kg being the best. GlcNH(2).HCl at dose of 250 mg/kg could enhance significantly the thymus index, and spleen index and could promote T lymphocyte proliferation induced by ConA. The antitumor effect of GlcNH(2).HCl is probably host-mediated and cytocidal.
