Spirulina shows promise in PDT
We explored the efficacy of a new cubic form of spirulina (CSP) in photodynamic therapy (PDT) for cancer treatment. In our study using tongue cancer cells, we compared CSP with its naturally occurring counterpart and another photosensitizer.
All three showed safety for normal cells, but while CSP and the natural form mainly caused apoptotic cell death, the other led to necrosis. We found that CSP is a promising option for cancer PDT, although caution is advised with higher concentrations of the other photosensitizer due to toxicity concerns.

We examined how C-phycocyanin (C-PC) impacts melanoma, a particularly aggressive skin cancer. In our study, we induced tumors in mice and subsequently treated them with C-PC for three days. We found that treatment boosted key immune cells and showed significant immunomodulatory effects, especially when tumors were present. Importantly, there was no damage to vital organs from the treatment. Our research highlights the potential role of C-PC in enhancing tumor immunity, suggesting promising avenues for future clinical trials in cancer treatment.

Spirulina is a source of plant protein and B vitamins, particularly B12, making it beneficial for vegetarians. While it aids in weight loss, healthy eating and exercise are still essential. Spirulina boosts the immune system, helps with anemia by increasing hemoglobin, and has anti-cancer properties through phycocyanin, which can inhibit cancer cell growth. It is vital to use it in moderation and consider its effects on the body.

We explored the anticancer potential of Spirulina maxima extract, particularly through a new delivery method called nanoemulsion. This approach effectively loaded the extract into tiny nanoparticles, making it more stable.
Our findings showed that this treatment significantly reduced cell viability in cancer cell lines and successfully inhibited tumor growth in mice. Notably, the treatment also normalized liver enzymes and decreased oxidative stress.
While the results are promising, it's essential to note that more research is needed to fully understand its effectiveness in cancer treatment.

Spirulina aids in testicular protection
We examined the potential of nano Spirulina platensis (NSP) to protect rat testicles from cisplatin-induced damage, a common chemotherapy drug. In a controlled study with groups receiving different treatments, we found that NSP significantly improved sperm quality, hormone levels, and overall testicular health compared to those receiving cisplatin alone. Notably, NSP also enhanced the expression of key genes involved in reproductive health. This suggests that NSP could be a beneficial support for mitigating the harmful effects of cisplatin on fertility.

We investigated an innovative system using Spirulina platensis and gold nanoclusters to enhance cancer radiotherapy. This approach is designed to work through several mechanisms, including producing oxygen when exposed to light.
The system effectively generates reactive oxygen species that can attack tumor cells and improve the sensitivity of radiation treatment. In studies with two cancer models, the results showed significant improvements in tumor reduction compared to standard treatments.
While promising, this research is still in its early phases, so further exploration is necessary to fully understand its potential in real-world applications.

Spirulina fermentation reduces cancer cell viability
We looked into how fermented Spirulina, produced under optimized conditions with specific bacteria and yeast, affects cancer treatment. In our testing, a unique production mode significantly reduced the viability of colon cancer cells by up to 72% without harming normal cell function.
This indicates that fermented Spirulina has potential as a supplementary food source with beneficial properties, particularly for cancer support. However, more research is needed to truly understand its bioactive compounds and their impact on human health.

Spirulina proteins show anticancer promise
We explored a novel technique to extract antioxidants and anticancer proteins from spirulina, a cyanobacterial biomass known for its beneficial properties. This method utilized ultrasound-assisted deep eutectic solvent extraction, optimizing extraction parameters to maximize protein yield and bioactivity.
Our findings revealed a protein yield of over 80% with impressive antioxidant capabilities. Notably, the extracted proteins showed significant cytotoxic effects against colorectal cancer cells while being safe for normal cells. This highlights spirulina’s potential as a natural ally in cancer treatment and health enhancement.

We investigated a new treatment using Spirulina platensis as an innovative embolic agent for tackling hepatocellular carcinoma (HCC). This microalgae formulation, loaded with doxorubicin, was designed to overcome challenges with current therapies by improving drug delivery and maintaining effectiveness in challenging tumor environments.
The treatment not only showed success in reducing tumor size in rat models but did so with minimal side effects due to the natural safety profile of Spirulina. These promising results suggest that DOX-SP may offer a viable solution for improving cancer treatment strategies in HCC.
