Xyloketal B Attenuates Fatty Acid-Induced Lipid Accumulation via the SREBP-1c Pathway in NAFLD Models.

The goal of this study was to examine the effects of xyloketal B on nonalcoholic fatty liver disease (NAFLD) and to explore the molecular mechanisms underlying its effects in both in vivo and in vitro models. We discovered an association between xyloketal B and the sterol regulatory element-binding protein-1c (SREBP-1c) signaling pathway, which is related to lipid metabolism. Mice were dosed with xyloketal B (5, 10 and 20 mg/kg/d) and atorvastatin (15 mg/kg/d) via intraperitoneal injection once daily for 40 days after being fed a high fat diet plus 10% high fructose liquid (HFD+HFL) for 8 weeks.

MicroRNA-134-3p is a novel potential inhibitor of human ovarian cancer stem cells by targeting RAB27A.

The cluster of microRNAs (miRNAs) in the DLK1-DIO3 genomic imprinted region contains several miRNAs that have a significant regulatory role in tumor proliferation and invasion. One of these miRNAs is miR-134-3p, and its expression changes significantly in human ovarian cancer stem cells (OCSCs) and in CD44-/CD133- ovarian cancer. The results of a luciferase assay showed that miR-134-3p silenced RAB27A by binding to the 3'-UTR of RAB27A mRNA.

[Optimization of Formulation of Panax notoginseng Saponins Transfersomes].

Objective: To optimize the formulation of Panax notoginseng saponins (PNS) transfersomes.

Methods: PNS transfersomes were prepared by film hydration-dispersion process. Based on the entrapment efficiency (EE) of ginsenoside Rg1 and ginsenoside Rb1, the effects of formulated quantity of sodium deoxycholate and cholesterol, the relative ion strength and pH value of hydration liquid were investigated.

Xyloketal B, a marine compound, acts on a network of molecular proteins and regulates the activity and expression of rat cytochrome P450 3a: a bioinformatic and animal study.

Natural compounds are becoming popular for the treatment of illnesses and health promotion, but the mechanisms of action and safety profiles are often unknown. Xyloketal B (XKB) is a novel marine compound isolated from the mangrove fungus Xylaria sp., with potent antioxidative, neuroprotective, and cardioprotective effects.

A validated high-performance liquid chromatographic method with diode-array detection for the estimation of xyloketal B in rat plasma.

A sensitive and specific HPLC-UV method was developed and validated for the determination of xyloketal B in rat plasma. Following liquid-liquid extraction, the separation was performed using an isocratic mobile phase of methanol-acetonitrile-water (30/30/40, v/v/v) on a Phenomenex C(18) column (4.6mm×250mm, 5μm).
