 Use of Methyl γ-linolenate


γ-Linolenic Acid methyl ester (Methyl GLA) is an esterified version of γ-Linolenic Acid (GLA), which is an ω-6 fatty acid, serves as melanoma cell proliferation inhibitors. γ-Linolenic Acid methyl ester inhibits ADP-induced blood platelet aggregation and induces apoptosis[1][2][3][4][5].

Description γ-Linolenic Acid methyl ester (Methyl GLA) is an esterified version of γ-Linolenic Acid (GLA), which is an ω-6 fatty acid, serves as melanoma cell proliferation inhibitors. γ-Linolenic Acid methyl ester inhibits ADP-induced blood platelet aggregation and induces apoptosis[1][2][3][4][5].

In Vitro γ-Linolenic Acid methyl ester (1-4 μg/mL; 72 h) induces apoptosis in vitro A-549 lung cancer cell lines using SRB assay. However GLA is due to its action at the gene/oncogene level and by altering BCl-2 expression[1]. Apoptosis Analysis[1] Cell Line: A-549 lung cancer cell line Concentration: 1, 2, 3, and 4 μg/mL Incubation Time: 72 hours; observed at 24 h, 48 h, and 72 h Result: Showed cytotoxicity potentially due to the induction of apoptosis of tumor cells by augmenting free radical generation only in the tumor cells but not normal cells.
In Vivo γ-Linolenic Acid methyl ester decreases the hepatic triglycerides and histological evidence of fatty liver induced by EtOH[2]. γ-Linolenic Acid methyl ester could significantly decrease levels of plasma total cholesterol (TC), triglycerides (TG), low density lipoprotein cholesterol (LDL-C), MDA, atherosclerosis index (AI) and liver TC, MDA, and increase levels of high density lipoprotein cholesterol (HDL-C) in both normal and hyperlipidemic rats[3]. Animal Model: Hepatic pathol rats model induced by EtOH (male Sprague-Dawley rats, 250-300 g)[2] Dosage: 90 mL, 50-60 mL Administration: Intraperitoneal injection; once daily; administrated 90 mL during day 1-5 and day 9, 50-60 mL during day 6-8 Result: Decreased the hepatic triglycerides of 25.6 mg/g compared with saline (40.2 mg/g) or olive oil (42.8 mg/g) treatment. Decreased liver index (the ratio of liver weight and body wight) in hyperlipidemic rats, but had no significant effect in normal rats.
