Use of LaminaranLaminaran is a neutral water-soluble β-1-3-glucan and a typical ligand for Dectin-1 isolated from the brown alga D. dichotoma, has potent immunomodulating, radioprotective, and anticancer activities[1]. Laminaran is made up of β (1→3)-glucan with β (1→6)-branches and can be catalyzed by enzymes such as laminarinase (EC 3.2.1.6) that breaks the β (1→3) bonds[2]. Laminaran is a promising immune stimulatory molecule for use in cancer immunotherapy[3]. |

| In Vitro | Laminaran (100-800 µg/mL; 24 hours) is not cytotoxic against normal epidermal cells JB6 Cl41 and human melanoma cells SK-MEL-28, the percentage of inhibition of living cells number is less than 15 % at concentrations range up to 800 µg/mL after 24 h of treatment[1]. Laminaran (200 µg/mL; 24-72 hours)does not cause any growth inhibition of SK-MEL-28 cells after 24 and 48 h of treatment, but decreases cells proliferation by 36 % after 72 h of treatment[1]. Laminaran (25-50 µg/mL; 24 hours) at low concentration does not influence the phosphorylation of c-Raf (Ser259), ERK1/2 (Tyr202/Tyr204), and MEK1/2 (Ser 221) kinases as well as total expression level of investigated proteins. But decreases p-MEK, p-ERK1/2 at 50 µg/mL[1]. Cell Viability Assay[1] Cell Line: JB6 Cl41 and SK-MEL-28 cells Concentration: 100, 200, 400, and 800 µg/mL Incubation Time: 24 hours Result: Showed no cytotoxic against normal epidermal cells JB6 Cl41 and human melanoma cells SK-MEL-28. Cell Proliferation Assay[1] Cell Line: SK-MEL-28 cells Concentration: 200 µg/mL Incubation Time: 24 hours Result: Decreased cell proliferation at 72 hours. Western Blot Analysis[1] Cell Line: SK-MEL-28 cells Concentration: 25 µg/mL; 50 µg/mL Incubation Time: 24 hours Result: Inhibited phosphorylation of c-Raf, MEK1/2, and ERK1/2 kinases. |
| In Vivo | Laminaran (intravenous injection; 12.5, 25, and 50 mg/kg; 21 days) and OVA (50 μg) combination significanly decreases the tumor masses when it compares with the PBS-, OVA-, and laminarin-treated mice[3]. Animal Model: C57BL/6 mice injected s.c. with B16-OVA cells[3] Dosage: 12.5, 25, and 50 mg/kg; 21 days Administration: Intravenous injection Result: Prevented B16-OVA tumor growth by inducing Ag-specific immune responses. |
