Fucoidan

Recent research studies have shown that the intestinal flora are related to the occurrence and progress of breast cancer. This study investigates the effect of fucoidan on intestinal flora and intestinal barrier function in rats with 7,12-dimethylbenz[a]anthracene (DMBA)-induced breast cancers. Sixty female

This experiment was conducted to compare the effect of adding fucoidal, probiotic and antibiotic in diet on performance, carcass characteristics, gut microbial population, and blood metabolism in broiler chicks. A total of 250 one-day-old Ross 308 broiler chickens were randomly distributed in 5 treatments with 5 replicates and reared for 42 days. After ...

The aim of the study was to assess the activity of fucoidan on the uterine sarcomas (MES-SA and ESS-1) and carcinosarcoma cell lines (SK-UT-1 and SK-UT-1B) and its toxicity on the human skin fibroblasts (HSF). Two uterine sarcomas and two carcinosarcoma cell lines were examined, as a control HSF were used. Cell viability was assessed with MTT test, apoptosis with caspase-3 activity and cell cycle by assessment of DNA synthesis. Fucoidan significantly decreases cell viability in SK-UT-1, SK-UT-1B, and ESS-1 cell lines, such effect was not observed in MES-SA. Fucoidan was not substantially affecting proliferation among normal cells. The tested agent induced apoptosis in all cell cultures used in the experiment. Fucoidan affects cell cycle of all tested cell lines except MES-SA by increasing percentage of cells in G0/sub-G1/G1 phase. Fucoidan do not only affect proliferation but induces apoptosis in selected uterine sarcoma and carcinosarcoma cell lines, so it has potential to be used as cytotoxic agent. Fucoidan seems to be promising anti-cancer agent for endometrial stromal sarcoma and carcinosarcoma.

Endometriosis is common in reproductive-age women and its pathology is to increase proliferation and migration to enhance epithelial-to-mesenchymal transition progression (EMT). However, treatments are currently limited, so it is important to explore new therapeutic drugs. Hence, in this study, we investigate the therapeutic effect of fucoidan (FC) on the progression and mechanisms of endometriosis. The cell viability of endometrial cell lines End1/E6E7 and Vk2/E6E7 treated with different concentrations of FC were assessed by 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and cell counting. Cell migration was evaluated using wound-healing assay. In an in vivo experiment, female Balb/c mice received surgically induced endometriosis followed by different concentrations of fucoidan for 6 weeks. High-frequency ultrasound imaging was applied to detect subsequent lesion growth. The results demonstrated that fucoidan inhibited the viability and migration ability of End1/E6E7 and Vk2/E6E7 cells. Additionally, the administration of fucoidan reduced the volume and weight of endometriotic lesions, decreased inflammatory cytokines and vascular endothelial growth factor (VEGF) of serum and lesions, and improved EMT proliferation and apoptosis-related protein expression. For the first time, fucoidan indicated anti-proliferative and anti-inflammatory effects as well as inhibited EMT progression and induced apoptosis, improving endometriosis.

Fucoidans are a class of sulfated fucose-rich polysaccharides found in brown marine algae and echinoderms. Fucoidans have an attractive array of bioactivities and potential applications including immune modulation, cancer inhibition, and pathogen inhibition. ...

Since our last review in 2015, the study and use of fucoidan has extended in several research areas. Clinical use of fucoidan for the treatment of renal disease has become available and human safety studies have been undertaken on radiolabeled fucoidan for the purpose of imaging thrombi. Fucoidan has been incorporated into an increasing number of commercially available supplements and topical treatments. In addition, new measuring techniques are now available to assess the biologically relevant uptake of fucoidans and to assist in production. Microbiome modulation and anti-pathogenic effects are increasingly promising applications for fucoidans, due to the need for alternative approaches to antibiotic use in the food chain. This review outlines promising new developments in fucoidan research, including potential future therapeutic use.
