“…In general, seaweeds are low in lipid content ranging from 1 to 3% (Mabeau and Fleurence, 1993). The lipid content previously reported for G. edulis was 0.83±0.1% (Sakthivel and Devi, 2015) and in G. acerosa, a related species, was 2.8±0.01% (Syad et al, 2013), which were higher than recorded in the present study for G. edulis.

In the present study, nutritional composition of the edible seaweeds, Gracilaria edulis (red seaweed), Ulva lactuca (green seaweed) and Sargassum sp. (brown seaweed) were evaluated. ). Palmitic acid (C16:0), oleic acid (C18:1) and linoleic acid (C18:2, ω-6) were the most abundant saturated fatty acid (SFA), monounsaturated fatty acid (MUFA) and polyunsaturated fatty acid (PUFA), respectively. Fatty acid profile also revealed that small quantity of docosahexaenoic acid (DHA) (C22:6, ω-3) ranging from 0.064 to 0.494% was present in all the three seaweed species but eicosapentaenoic acid (EPA) (C20:5, ω-3) was present only in Sargassum sp. at a concentration of 0.583%. G. edulis had higher vitamin D2 (2.590 mg 100 g -1 ), vitamin E (1.017 mg 100 g -1 ) and vitamin K1 (0.714 mg 100 g -1 ) than Sargassum sp. and U. lactuca. The results clearly indicates that these three seaweeds can be considered as a good source of dietary fibre, protein, minerals and vitamins and can be used for fortifying foods or as components of functional foods.

The laver (Porphyra tenera), red seaweed, has been reported to have anticancer activity, but little is known about its molecular mechanisms of action. The objective of this study was to determine the effects of laver extract on cancer cell proliferation, invasion, and metastasis in SK-Hep1 cells using migration and invasion assays. We also investigated the relationship of MMP-2/-9 and TIMP-1/-2 expression at both the protein and gene level in SK-Hep1 human hepatoma carcinoma cells after laver extract treatment. Laver extract inhibited cancer cell growth in a dose-dependent manner. In an invasion assay conducted in Transwell chambers, laver extract showed 19.6 and 27.2% inhibition of cancer cell at 200 and 400 μg/mL, respectively, compared to the control. The mRNA levels of both MMP-2 and MMP-9 were down-regulated by laver extract treatment in a dose-dependent manner. Laver extract, at 400 μg/mL, was inhibited by MMP-2 and MMP-9 expressions by 70.1 and 77.0%, respectively. An inverse relationship in the mRNA contents of MMP-2/-9 and TIMP-1/-2 expressions in SK-Hep1 cells was found by laver extract treatment. Our results demonstrate antimetastatic properties of laver extract in inhibiting the adhesion, invasion, and migration of SK-Hep1 human hepatoma cancer cells.
