Pectic polysaccharide from corn (Zea mays L.) effectively inhibited multi-step mediated cancer cell growth and metastasis.

Only registered users can translate articles

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

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:

Suppressive effect of pectic polysaccharides extracted from Rauwolfia verticillata (Lour.) Baill.var.hainanensis Tsiang on inflammation by regulation of NF- κ B pathway and interleukin-17 in mice with dextran sulphatesodium-induced ulcerative colitis.

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 (Decalepis hamiltonii) pectic oligosaccharide (SRO1) induces cancer cell death via modulation of galectin-3 and survivin.

Only registered users can translate articles

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

Ripening-induced chemical modifications of papaya pectin inhibit cancer cell proliferation.

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

Disruption of galectin-3 and galectin-3 binding protein (G3BP) interaction by dietary pectic polysaccharides (DPP) - Arrest of metastasis, inhibition of proliferation and induction of apoptosis.

Only registered users can translate articles

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 Oligosaccharide from tomato exhibiting anticancer potential on a gastric cancer cell line: Structure-function relationship.

Only registered users can translate articles

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).

Pectic polysaccharide isolated from Angelica gigas Nakai inhibits melanoma cell metastasis and growth by directly preventing cell adhesion and activating host immune functions.

Only registered users can translate articles

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

Polysaccharides from ginseng leaves inhibit tumor metastasis via macrophage and NK cell activation.

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.

Structural characterization and anti-A549 lung cancer cells bioactivity of a polysaccharide from Houttuynia cordata.

Only registered users can translate articles

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

Antimetastatic pectic polysaccharide from Decalepis hamiltonii; galectin-3 inhibition and immune-modulation.

Only registered users can translate articles

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

Structural characterization and antitumor activity of a pectic polysaccharide from the roots of Angelica acutiloba.

Only registered users can translate articles

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

Antitumor metastasis activity of pectic polysaccharide purified from the peels of Korean Citrus Hallabong.
