The fruit of Pandanus tectorius (PTF) has a long history of use as a folk medicine to treat hyperlipidemia in Hainan province, South China. Our previous studies have shown that the n-butanol extract of PTF is rich in caffeoylquinic acids and has an adequate therapeutic effect on dyslipidemic animals induced by high-fat diet. In this work, seven caffeoylquinic acids isolated from PTF were screened for the lipid-lowering activity in HepG2 hepatoma cells. Oil-Red O staining, microscopy and intracellular triglyceride (TG) and total cholesterol (TC) quantification showed that 3-O-caffeoylquinic acid (3-CQA), 3, 5-di-O-caffeoylquinic acid (3,5-CQA), and 3,4,5-tri-O-caffeoylquinic acid (3,4,5-CQA) significantly inhibited lipid accumulation induced by oleic acid and decreased intracellular levels of TC and TG in a dose-dependent manner. These three caffeoylquinic acids showed no significant cytotoxicity at concentrations of 1 -50 μmol x L(-1) as determined by MTT assay. Realtime quantitative PCR revealed that 3-CQA and 3, 5-CQA significantly increased the expression of lipid oxidation-related genes PPARα, CPT-1 and ACOX1 while 3-CQA, 3, 5-CQA and 3,4,5-CQA decreased the expression of lipogenic genes SREBP-1c, SREBP-2, HMGR, ACC, FAS. Overall, 3-CQA, 3, 5-CQA and 3, 4, 5-CQA may be the principal hypolipidemic components in PTF which can decrease intracellular lipid accumulation through up-regulating the expression of lipid oxidative genes and down-regulating the expression of lipogenic genes.

Objective To investigate the effects of down-regulating uncoupling protein-2 (UCP-2) expression on acute damage to fatty liver cells and explore a new target for the donor liverwith steatosis. Methods Primary fatty liver cells were isolated from C57BL/6J-ob/ob transgenic miceby two-step collagenase perfusion method. RNAi lentivirus vector targeting mouse UCP-2 gene wasused to knock down the UCP-2 gene in the steatosis hepatocytes (the experimental group). Emptylentivirus vector was transfected into the steatosis hepatocytes cells as the control group. Under thefluorescence microscopy, the transfection efficiency was tested. Real time PCR was used to determinethe effect of RNAi. After the transfected cells were treated with TNF-α for 24 h, apoptosis wasanalyzed by flow cytometry using PI staining. Activation of caspase3 was detected by Western blot.Resalts The expression of UCP-2 gene was inhibited effectively, and the knockdown rate of UCP-2gene was 75%. The apoptosis rate in the experimental group was (4.97±0.25)%, significantlylower than in the control group [(21.13±1.28)%, p<0.05 ]. Activation 'of caspase3 in theexperimental group was also weaker than in the control group. Conclusion Inhibiting the expression ofUCP-2 can attenuate the injury of fatty liver cells.

Polo-box domain 1 (PBD1) is a characteristic domain of polo-like kinase 1 (PLK1), which locates in C-terminal and can influence the catalytic activity and specific subcellular locations of PLK1. At present, most PLK1 inhibitors are developed to occupy the ATP pocket or its close sites. However, this kind of PLK1 inhibitors is difficult to pursue target selectivity and may encounter cross drug resistance with other kinase inhibitors due to the conserved sequence of ATP pocket. Recently, PBD1, with aberrant specificity in sequence and structure, has attracted enormous interests as the alternative target to the discovery of corresponding inhibitors for anti-tumor drugs. The structure and function of PBD1 as well as the advances of its inhibitors are reviewed in this paper.

This study examined the mRNA expression of NALP3 in the spleen of the mice with hypersplenism due to portal hypertension (PH). The mouse hypersplenism models were established by oral administration of tetrachloromethane (2 mL/kg/week for 12 weeks by oral gavage). All the mice were randomly divided into a control group and an experimental group. The blood routine test was conducted, spleen index was calculated and spleen was histologically examined. Portal vein sera were taken for detection of the level of uric acid. The mRNA expressions of NALP3 and IL-1beta in the spleen were detected by reverse transcriptase-polymerase chain reaction (RT-PCR). The results showed that the platelet count was significantly lower in the experimental group [(674+/-102)x10(9)/L] than in the control group [(1307+/-181)x10(9)/L] (P<0.05), while the spleen index was significantly higher [(9.83+/-1.36) mug/g] in the experimental group than in the control group [(4.11+/-0.47) mug/g] (P<0.05). The histopathological changes of spleen followed the pattern of congestive splenomegaly. No significant difference was found in the uric acid level in the portal vein between the control group and the experiment group. The mRNA expressions of NALP3 and IL-1beta were up-regulated significantly in the spleen in the experimental group as compared with those in the control group (P<0.05). It was concluded that NALP3 and IL-1beta may play important roles in the pathogenesis of hypersplenism.
