The effects of pure gamma-linolenic acid (GLA; C18:3, n-6) and dihomo-gamma-linolenic acid (DGLA; C20:3, n-6) were investigated in 7,12-dimethylbenz(alpha)anthracene (DMBA) (10 mg/rat)-induced mammary tumors in Sprague-Dawley rats. 0.15 g of GLA, DGLA, or corn oil (CO) were administered (two times
We previously demonstrated that knockdown of delta-5-desaturase via siRNA transfection together with dihomo-γ-linolenic acid supplementation inhibited colon cancer cell growth and migration, by promoting the production of the anti-cancer byproduct 8-hydroxyoctanoic acid from OBJECTIVE
To compare the tumoricidal efficacy of meglumine gamma-linolenic acid (MeGLA), mitomycin C, epirubicin and water on two urothelial cell lines, and to establish the effect of serum protein levels derived from bladder cancer resection craters on the action of these agents.
METHODS
The human
To pursue a systemic administration of alpha-linolenic acid (ALA), which is a selective cytotoxic agent, we formulated an ALA o/w-emulsion stabilized by cholesterol-bearing pullulan (CHP-55-2.1) and trioctanoylglyceride (TriC8). This emulsion was stable even in the presence of bovine serum albumin
Inhibition of Ehrlich ascites carcinoma respiration by aqueous extracts of oxidized linoleic or linolenic acid (aqueous emulsions UV-irradiated, 90 min) was associated entirely with relatively involatile compounds which were both thiobarbituric acid (TBA)-reactive and peroxidase-reactive. Inhibitory
The nude mouse human tumour xenograft system was used as an in vivo model to investigate the possible effect of gamma-linolenic acid (GLA) both on established tumour xenografts and as a prophylactic agent prior to tumour induction. Eighty-nine nude mice bearing a range of different human tumours
This study investigated the effect on drug uptake in multidrug resistant cells by the incorporation of the essential fatty acid gamma-linolenic acid (GLA). The cell lines used were the MCF-7/R resistant human breast cancer and MGH-U1/R bladder cancer. Uptake of drug (doxorubicin, epirubicin,
The essential fatty acid gamma-linolenic acid (GLA) is an effective cytotoxic agent when applied topically and for prolonged periods to tumour cells. Topical application, by intravesical therapy, is firmly established in the treatment of superficial bladder cancer. However, this form of therapy is
It has been suggested that exogenous unsaturated fatty acids (UFAs) may increase the cytotoxic activity of cancer chemotherapeutic agents. We examined how y-linolenic acid (GLA; 18: 3n-6), the most promising UFA in the treatment of human tumors, affects the effectiveness of the lipophilic drug
E-cadherin is a cell to cell adhesion molecule which acts as a suppressor of metastasis. This study examined the effect of gamma-linolenic acid (GLA), a n-6 polyunsaturated fatty acid, on the expression of E-cadherin in human cancer cells. Western blotting studies demonstrated that treatment of
BACKGROUND
Epidemiologic and experimental studies suggest that dietary fish oil and vegetable oil high in omega-3 polyunsaturated fatty acids (PUFAs) suppress the risk of colon cancer. The optimal amount to prevent colon carcinogenesis with perilla oil high in omega-3 PUFA alpha-linolenic acid in a
α-Linolenic acid (ALA, 18:3n-3) and γ-gamma linolenic acid (GLA, 18:3n-6) are polyunsaturated fatty acids (PUFA) that improve the human health. The present study focused on testing the in vitro antitumor actions of pure ALA and GLA on the HT-29 human colorectal cancer cell line.
Alpha-linolenic acid (ALA)-enriched diacylglycerol (DAG) oil is an edible oil enriched with DAG (>80%) and ALA (>50%). The present study investigated whether ALA-DAG oil promotes tumorigenesis in the tongue and gastrointestinal tract, using a rat medium-term multi-organ carcinogenesis bioassay
Highly unsaturated fatty acids (HUFAs) are naturally occurring anti-tumour agents. HUFAs act as intracellular signalling molecules in cell proliferation and death. In human glioma, HUFAs may stimulate tumour regression and apoptosis. An implantation glioma model, using the C6 glioma cell line, was
Maspin, mammary serine protease inhibitor, is a recently identified tumour suppressor and has a profound effect on cell motility. This study examined the effect of gamma linolenic acid (GLA), an essential fatty acid (EFA) with anticancer properties, on the expression of maspin and motility of cancer
