pectic polysaccharide/悪性腫瘍

Corn pectic polysaccharide (COPP) inhibited galectin-3 mediated hemagglutination at Minimum Inhibitory Concentration (MIC) of 4.08 μg/mL as opposed to citrus pectin (25 μg/mL), a well known galectin-3 inhibitor and lactose (4.16 μg/mL)--sugar specific to galectin-3. COPP effectively (72%) inhibited

The present study investigated the antineoplastic effects of pectic polysaccharides that were extracted from green sweet pepper (Capsicum annuum [CAP]) in the Ehrlich carcinoma in mice and in human mammary tumor lineages. After the subcutaneous inoculation of 2 × 106 Ehrlich tumor cells, Female

This study was to investigate the effects and mechanisms of pectic polysaccharides (PP) extracted from Rauvolfia verticillata (Lour.) Baill. var. hainanensis Tsiang on dextran sulphate sodium (DSS)-induced ulcerative colitis (UC). Eighty female BALB/c mice were randomly divided into four groups:

OBJECTIVE To investigate the effects of pectic polysaccharides extracted from Rauwolfia verticillata (Lour.) Baill.var.hainanensis Tsiang on an experimental murine colitis model. METHODS Experimental colitis was induced by dextran sulfate sodium (DSS), and mice were divided into 4 groups: control,

Swallow root pectic oligosaccharide fraction (SRO1) from swallow root pectic polysaccharide (SRPP) possessed a molecular size of 831 Da. Structural analysis revealed that it is a rhamnogalacturonan I type, bearing arabinogalactan side chain with β-d-(1→4) galactose along with α-l-Araf (1→5)-α-l-Araf

Papaya (Carica papaya L.) is a fleshy fruit with a rapid pulp softening during ripening. Ripening events are accompanied by gradual depolymerization of pectic polysaccharides, including homogalacturonans, rhamnogalacturonans, arabinogalactans, and their modified forms. During intermediate phases of

Galectin-3 and galectin-3 binding proteins (G3BP) are implicated as key players in metastasis. In the current study, we evaluated the effect of pectic polysaccharides on galectin-3 and G3BP mediated metastasis in vitro (cells) and in vivo (tissues). In vitro study (double immunostaining) confirms

Pectic Polysaccharide (PP) from dietary sources has been known to prevent cancer growth and hence impede cancer progression. We evaluated anticancer effect of Pectic-Oligosaccharide isolated from Sour Raw Tomato (SrTPO); its bioavailability and structure elucidated from purified fraction (SrTPO1).

The pectic polysaccharide (angelan) of Angelica gigas Nakai is an immunostimulator that activates the immune functions of B cells and macrophages. Here we investigated the effect of angelan on tumor growth and metastasis. Angelan was found to significantly prolong the survival rate of

In this study, we purified the polysaccharide fraction (GS-P) from the leaves of Panax ginseng C.A. Meyer and analyzed its monosaccharide composition and antitumor and antimetastatic activity in vitro and in vivo. GS-P is a 10.2kDa pectic polysaccharide consisting of 15 different monosaccharides.

A water-soluble pectic polysaccharide HCA4S1 was isolated from Houttuynia cordata and purified by DEAE Cellulose and Sephacryl S-300 column. HCA4S1 with an average molecular weight of 21.7 kDa mainly consisted of rhamnose, galacturonic acid, galactose, and arabinose. By using partial acid

Melanoma is a malignant neoplasm of major concern because of its high mortality rate and failure of chemotherapy. Previously we have shown that galectin-3, a galactose specific lectin, plays a pivotal role in the initiation of metastasis. It was hypothesized that blocking galectin-3 with galactose

The polysaccharide fraction from the root of Angelica acutiloba Kitagawa showed a potent antitumor activity against ascitic form of Sarcoma-180, IMC carcinoma, and Meth A fibrosarcoma as well as the solid form of MM-46 tumor. An active polysaccharide, AR-4E-2, was purified by precipitation with

A polysaccharide fraction, HBE-III, was successfully purified in a high yield (40.4%) from its crude polysaccharide (HBE-0) which was prepared from pectinase hydrolysates of the peels of the Korean Citrus Hallabong. In experimental lung metastasis studies of Colon 26-M3.1 carcinoma cells,

Three polysaccharide complexes (PSCs) were isolated from the aerial parts of common purslane (Portulaca oleracea L.), and the flowers of common lavender (Lavandula angustifolia Mill.) and silver linden (Tilia tomentosa Moench) by boiling water extraction and ethanol precipitation. The chemical
