71 ± 25 401.51 pg ml-1) and placebo group (30 502.81 ± 19 003.18 pg ml-1). Also, leptin concentration in the Plantago group at completion correlated positively with an increase in VEGF-A level (R = 0.45), and baseline VEGF-A level correlated negatively with the increase in leptin concentration (R = -0.47). Plantago major supplementation increases leptin serum level, enhances leptin influence on VEGF-A serum level increase and by this mechanism may intensify endothelial dysfunction and angiogenesis in obese women.Hepatocellular carcinoma (HCC) is one of the most common malignant tumors. The prognosis of HCC is very poor due to the absence of symptoms and a lack of effective treatments. Studies have shown that various Foeniculum vulgare (fennel) extracts exhibit anti-cancer effects on malignant tumors such as skin cancer and prostate cancer. However, the anti-tumor activity of Foeniculum vulgare and its underlying molecular mechanisms towards HCC are unknown. Here, we provide fundamental evidence to show that the 75% ethanol extract of Foeniculum vulgare seeds (FVE) reduced cell viability, induced apoptosis, and effectively inhibited cell migration in HCC cells in vitro. HCC xenograft studies in nude mice showed that FVE significantly inhibited HCC growth in vivo. Mechanistic analyses showed that FVE reduced survivin protein levels and triggered mitochondrial toxicity, subsequently inducing caspase-3 activation and apoptosis. Survivin inhibition effectively sensitized HCC cells to FVE-induced apoptosis. Moreover, FVE did not induce a decrease in survivin or apoptotic toxicity in normal liver cells. Collectively, in vivo and in vitro results suggest that FVE exerts inhibitory effects in HCC by targeting the oncoprotein survivin, suggesting FVE may be a potential anti-cancer agent that may benefit patients with HCC.We investigated the extraction, purification, physicochemical properties and biological activity of Ligusticum chuanxiong polysaccharides (LCXPs). Two polysaccharide fractions (Ligusticum chuanxiong [LCX]P-1a and LCXP-3a) were obtained by DEAE Sepharose™ Fast Flow and Sephacryl™S-300 high resolution column chromatography. The results showed that the molecular weight of LCXP-1a and LCXP-3a was 11.159 kDa and 203.486 kDa, respectively. LCXP-1a is composed of rhamnose, glucuronic acid, galacturonic acid, and glucose at a molar percentage of 0.52  1.88  1.06  95.36, But LCXP-3a has another molar percentage of mannose, rhamnose, glucuronic acid, galacturonic acid, glucose, galactose, xylose, arabinose, and fucose of 0.64  6.69  1.03  43.74  2.20  26.90  0.82  15.94  1.80. Both LCXP-1a and LCXP-3a could stimulate macrophages to produce NO, TNF-α, IL-6, and IL-12p70. Co-culturing macrophages and hepatocellular carcinoma cells showed that LCXP-1a and LCXP-3a inhibited the growth of HepG2 and Hep3B through immunoregulation. They arrested the cell cycle at the G0/G1 phase and promoted apoptosis. Moreover, there was no cytotoxicity to the hepatocyte cell line, LO2. We also noted that the immunomodulatory activity and anti-tumor activity of LCXP-3a were significantly better than those of LCXP-1a. Our data demonstrate that LCXP-3a is potentially a well-tolerated and effective immunomodulatory adjuvant cancer treatment.Gynura procumbens (Lour.) (GP), which is an edible herb, has been shown to have prominent anti-hyperglycemic activity. NSC 303580 Nevertheless, the complex chemical composition of GP has impeded clarification of the molecular mechanisms of its effects on type 2 diabetes mellitus (T2DM). In this study, we adopted a network pharmacology approach for the exploration of the potential mechanisms of GP on T2DM. The results suggested that the PI3K/Akt signaling pathway plays a momentous role in the effects of GP. Therefore, we further investigated the effects of GP on T2DM and the mechanism of action based on the PI3K/Akt signaling pathway. In vitro experiments showed that GP ameliorated insulin resistance (IR) and glucose metabolism, thus indicating marked hypoglycemic activity. In vivo experiments showed that blood glucose, liver damage, and insulin sensitivity were ameliorated by GP intervention. Furthermore, the results of RT-PCR and western blot analyses revealed that GP regulated IR and glucose metabolism via the PI3K/Akt signaling pathway. In summary, these results indicate that GP intervention ameliorates T2DM by activating the PI3K/Akt signaling pathway.Cadmium (Cd) induces hepatocyte injury by oxidative stress. Albicanol is a sesquiterpenoid extracted from the medicinal plant Dryopteris fragrans that has previously been shown to exhibit anti-aging and antioxidant activity. In this study, we explored the mechanism of albicanol inhibition of the Cd-induced apoptosis of chicken hepatoma cells (LMH) by treating these cells with CdCl2 (25 μM) and/or albicanol (2.5 × 10-5 μg mL-1) for 24 h. Under Cd treatment, the research results showed that the apoptosis rate markedly increased in LMH cells. In addition, the iNOS activity and NO content increased significantly, which promoted the expressions of genes associated with the mitochondrial apoptosis pathway (Bax, CytC, Caspase-3 and Caspase-9) and inhibited the expression of Bcl-2 in this pathway. However, Cd + albicanol co-treatment significantly reduced the apoptosis rate and the expressions of iNOS and genes associated with the mitochondrial apoptosis pathway (Bax, CytC, Caspase-3 and Caspase-9), and promoted the expression of Bcl-2 in this pathway. In addition, molecular docking supported a link between the albicanol ligand and the iNOS receptor. These results indicated that albicanol can inhibit Cd-induced apoptosis by regulating the NO/iNOS-mediated mitochondrial pathway.A simple and sensitive fluorometric method is developed utilizing aggregation-induced emission probe based silica nanoparticles for the detection of nitroaromatic explosives. A positively charged tetraphenylethene based probe (TPE-C2-2+) is doped into silica nanoparticles exploiting electrostatic interactions to produce TPE-SiO2 nanoparticles with a uniform particle size. The TPE-SiO2 nanoparticles exhibit strong fluorescence emission due to the aggregation-induced emission (AIE) effect of the doped TPE probe. The fluorescence emission of TPE-SiO2 offers quantitative and sensitive response to picric acid (PA), 2,4-dinitrotoluene (DNT) and 2,4,6-trinitrotoluene (TNT) which are used as model examples of nitroaromatic compounds. The fluorescence spectroscopy results show that the fluorescence emission of TPE-SiO2 was greatly quenched in the presence of the electron-poor nitroaromatic compounds due to the inner filter effect (IFE) and possibly the contact quenching mechanism. TPE-SiO2 nanoparticles show better sensitivity towards PA and could detect PA down to 0.
