Anti-Cancer Activity of Spirulina - Lung Cancer and Pancreatic Cancer

Functional foods show non-toxic bioactive compounds that offer health benefits beyond their nutritional value and beneficially modulate one or more target functions in the body.

Spirulina stands out for its rich composition of bioactive compounds, as well as unsaturated fatty acids and essential amino acids, which contribute to basic human nutrition and can be used as a protein source for diets free from animal products.

In addition, spirulina has colored compounds, such as chlorophylls, carotenoids, phycocyanins, and phenolic compounds, and natural antioxidants that support its anticancer, neuroprotective, probiotic biological activities and immune system stimulating effect.

Improvement of immune system and antitumor activity

In addition to probiotic effects, microalgae derivatives have the potential to improve the immune system and antitumor activity.

The increase in the immune response, through the induction of tumor necrosis, phagocytosis, and the production of interleukin, results from the wide range of sulfate groups, sulfate esters, and amine residues present in spirulina polysaccharides.

The antioxidant activity of spirulina is also associated with activity against lung cancer cells.

Microalgae extract affects the cell cycle of the A549 lung cancer cell line, increasing the production of reactive oxygen species and cell membrane lipid peroxidation.

An extract of Spirulina demonstrated inhibitory effects on the migration and invasion of pancreatic cancer (PA-TU-8902).

Furthermore, the extract allowed the regulation of mRNA and VEGF-A protein expressions in tumor cells, inhibited ERK activation and suppressed the expression of ERK-regulated proteins.

Conclusion

Spirulina's potential for cancer cell treatments lies mainly in the significant inhibitory effects on cancer cells while protecting normal cells. 

The anticancer effect of Spirulina was associated with suppressive effects on the migration and invasiveness of tumor cells with different antiangiogenic characteristics.

Curated by Spiruliving Institute

Spiruliving Institute is a non-profit dedicated to building awareness of the benefits of fresh and fresh-frozen (never dried) spirulina for cancer prevention, as an alternative and/or complementary treatment, and as a functional treatment for cancer survivors to boost health and prevent cancer recurrence. We curate independent research and make it available to the public.
