Heparanase activity correlates with the metastatic potential of tumor cells. Moreover, the anti-metastatic effect of non-anti-coagulant species of heparin and certain sulfated polysaccharides was attributed to their heparanase-inhibiting activity. We investigated the effect of a chemically sulfated
A number of scientific studies have revealed that laminarin has antitumor effects. Therefore, the aim of the present study was to investigate the apoptosis of LoVo cells and the underlying mechanisms induced by laminarin. LoVo cells were treated with various concentrations of laminarin and
The B-cell-specific Moloney leukemia virus inset site 1 gene (BMI-1) has attracted considerable attention in recent years because of its key role in breast cancer development and metastasis. The downregulation of BMI-1 expression via small interfering RNA (siRNA) effectively inhibits tumor growth.
OBJECTIVE
To study the effect of laminarin sulphate (LAMS) on the expressions of PTEN and P27kip1 in androgen-independent prostate cancer PC-3 cells in vitro, and investigate the mechanism of its anti-tumor action.
METHODS
The inhibitory effects of different concentrations of LAMS (0, 50, 100, 200
In order to improve the anti-cancer therapy efficiency of hydrophobic drugs such as curcumin (Cur), a novel dual pH/redox sensitive marine laminarin-based nanomedicine carrier biomaterial with photo-dynamic therapy (PDT) was synthesized in this study. The new synthetic chemical structure, named as
This research evaluates the effects of laminarin on the maturation of dendritic cells and on the in vivo activation of anti-cancer immunity. In vivo treatment of C56BL/6 mice with laminarin increased the expression levels of co-stimulatory molecules and the production of pro-inflammatory cytokines
Laminarin, found in marine brown algae, is used as a carbohydrate reserve for phytoplankton; however, it is also used in traditional Chinese medicine, and has been shown to have several biological activities, including anticancer activities. In this study, we examined the mechanisms through which
Many scientific studies have shown that laminarin has anti-tumor effects, but the anti-tumor mechanism was unclear. The purpose of this study was to investigate the effect of laminarin on the induction of apoptosis in human colon cancer LOVO cells and the molecular mechanism involved. LOVO cells
Ovarian cancer (OC) is difficult to diagnose at an early stage and leads to the high mortality rate reported in the United States. Standard treatment for OC includes maximal cytoreductive surgery followed by platinum-based chemotherapy. However, relapse due to chemoresistance is common in advanced
The aim of this study was to investigate the sulfated modification of laminarin and the changes in structure and antitumor activity. The chlorosulfonic acid-pyridine method was applied for sulfated modification. The molecular weights of laminarin and laminarin sulfate (LAMS) were measured by
The combination of traditional Chinese medicines can improve the efficacy of cancer treatment. Furthermore, the combination of the traditional Chinese medicine curcuma zedoary and kelp was used to enhance the effect of the dissipation of blood stasis in pediatrics during the Song Dynasty. Curcumenol
Laminarin conjugate-based nano-scaled particles were in this study proposed as a delivery system for protoporphyrin IX (Pp IX) in photodynamic therapy (PDT) of human breast cancer cells (MCF-7). Hematin-Laminarin-Dithiodipropionic Acid-MGK, named as HLDM, was an amphiphilic carrier material with
Recent developments of innovative anticancer therapies are based on compounds likely to stimulate the immune defense of the patients. β-(1 → 3)-Glucans are natural polysaccharides well-known for their immunostimulating properties. We report here on the synthesis of small oligo-β-(1 → 3)-glucans
Laminarin is a polysaccharide isolated from brown algae that has various biological and pharmacological activities, such as antioxidant and anti-inflammatory properties. We recently reported that pretreated laminarin exerted neuroprotection against transient forebrain ischemia/reperfusion (IR)
The ocean is par excellence a fertile territory of biodiversity on our planet. Marine-derived polysaccharides have been applied as functional materials in biomedicine due to their attractive bioactive properties, safety, high availability and low-cost production. Laminarin (or laminaran), a low
