We examined how a selenium-containing drug, known as RuSe, targets cancer cells while sparing normal cells. This innovative approach leverages the unique properties of selenium, specifically its electrophilic center, to create oxidative stress within cancer cells. By shuttling electrons from biological electron donors, the drug activates a sequence of events detrimental to cancer survival.
The results were striking; we found that the rate of electron transfer at the selenium site is significantly higher in cancer cells compared to normal cells—1.81 times greater, to be precise. This selective action leads to a lethal effect, with the drug being 14.98 times more harmful to cancer cells than to their healthy counterparts. We observed that the generation of superoxide anions from this process causes DNA damage and triggers the p53 signaling pathway, which enhances the drug's effectiveness in killing cancer cells.
Our findings offer an exciting new avenue for crafting chemotherapeutic agents that can be both efficient and less toxic. By exploiting the special properties of selenium, we open the door to more intelligent and targeted cancer therapies that could reduce side effects for patients.

We aimed to understand the impact of selenium-enriched Akkermansia muciniphila (Se-AM) on colon cancer, specifically looking at its effectiveness in treating tumors in mice. By enriching the probiotics with inorganic selenium, we prepared Se-AM and evaluated its performance against colon cancer cells using a mouse model.
Our findings revealed that Se-AM was effective in killing colon cancer cells, notably the CT26 cells. The effectiveness seemed to depend on the concentration, indicating that higher doses were better at destroying these cancer cells. In addition to this direct killing effect, we saw that Se-AM played a therapeutic role in mice with established tumors by reducing tumor size and positively altering inflammatory markers in the colon.
Importantly, treatment with Se-AM restored gut microbiota diversity back to levels similar to healthy controls. We observed a notable increase in beneficial bacteria, which suggests that Se-AM not only addresses cancer cells but also promotes a healthier gut environment. Furthermore, we didn't find any adverse effects on vital organs in the mice, highlighting the safety of this treatment.
Overall, our work indicates that Se-enriched Akkermansia muciniphila has promising potential in the fight against colon cancer, providing both direct anti-cancer effects and supporting gut health.

We investigated the impact of selenium nanoparticles (SeNPs) on enhancing treatment for advanced non-small-cell lung cancer (NSCLC). Our research revealed that selenium deficiency is linked to immune dysfunction in patients, contributing to cancer progression. In experiments with mice, low selenium led to weakened immunity and faster tumor growth.
Importantly, we found that SeNPs can improve the effectiveness of chemotherapy drugs by promoting the immune response. A clinical trial showed striking results with an 83.3% response rate and 100% disease control with SeNPs in combination with standard treatments. Thus, selenium is shown to significantly support cancer therapy.

Selenium nanoparticles show cancer potential
We focused on the potential of selenium nanoparticles (SeNPs) derived from the medicinal plant Indigofera aspalathoides in treating cancer, particularly its hepatoprotective capabilities. In our exploration, we utilized an ethanolic extract of the plant to green-synthesize SeNPs and then characterized them using several analytical techniques.
The particle sizes were found to be between 50-80 nm, ensuring they are both stable and effective for biological interactions. We evaluated their antioxidant activity and cytotoxic effects, particularly on breast cancer (MCF-7) and liver cancer (HepG2) cell lines. The SeNPs exhibited impressive antioxidant properties, with a DPPH scavenging rate of 70.32% and hydroxyl radical scavenging at 73.68%.
Notably, we discovered that the SeNPs provided significant protection to liver cells at a concentration of 88 μg/mL, maintaining 100% cell viability. However, we also identified that higher selenium concentrations could lead to cytotoxicity. Our findings highlight selenium nanoparticles as promising candidates for addressing oxidative stress and liver-related disorders while offering potential benefits in cancer treatment.

We synthesized thirty selenium-containing coumarin derivatives and tested their effectiveness against various malignant tumor cell lines. Notably, one compound, referred to as 11i, showed remarkable potency against SK-N-SH neuroblastoma cells, with a low inhibitory concentration of just 2.5 μM.
Our experiments demonstrated that compound 11i significantly inhibited not only cell proliferation but also migration and invasion. Through several analyses, we observed an increase in the Bax/Bcl-2 protein expression ratio, which is a marker for apoptosis, alongside the release of Cytochrome C from the mitochondria. This process triggered apoptosis via the mitochondria-mediated pathway, effectively inducing cell death in neuroblastoma.
Moreover, we noted that the compound localized within the cytoplasm and interacted closely with mitochondria, suggesting it may disrupt normal mitochondrial functions. Computational docking studies supported these findings, showing that compound 11i bound strongly to Bcl-2 and mitochondrial G-quadruplexes.
In in vivo studies, using a mouse model of neuroblastoma, compound 11i exhibited impressive anti-tumor effects, achieving tumor inhibition rates of 79% and 93% at doses of 10 and 20 mg/kg, respectively. These results indicate the potential of selenium-containing coumarin derivatives as promising candidates for developing new treatments against neuroblastoma.

We investigated the potential of selenium nanoparticles, specifically those derived from Spirulina platensis, as a treatment for cancer. The study focused on understanding how these nanoparticles might impact cancer cells, which is an important area of research given selenium's reputation for health benefits.
Through our evaluation, we discovered that these selenium nanoparticles were effective in reducing the viability of certain cancer cell lines, including breast adenocarcinoma (MCF-7) and ovarian cancer (SKOV-3). At a concentration of 100 µg/ml, we saw a decrease in cell viability by 17.6% and 14.9%, respectively. This suggests that Spirulina-derived selenium could offer a pathway for developing new cancer treatments, although more research is needed to understand the full scope of its effects.
Besides their cancer-fighting potential, these selenium nanoparticles demonstrated a range of additional beneficial properties, such as antibacterial, antioxidant, and anti-inflammatory effects. This multifaceted effectiveness could make them valuable in various therapeutic contexts, not just for cancer.

Exploring selenium's cancer treatment potential
We explored a fascinating approach to improve cancer treatment through a unique combination of selenium and probiotics. The study focused on a special type of probiotic called Bifidobacterium longum, which was combined with selenium nanoparticles to create a powerful tool for fighting tumors.
The resulting product, BL@SeNPs, has been shown to selectively target the hypoxic areas of tumors—regions often tough for treatments to penetrate. Once attached to tumor cells, these selenium nanoparticles help stop their growth while boosting the generation of reactive oxygen species. This increased activity damages the cancer cells’ DNA, leading to enhanced effects of radiotherapy and potentially kicking off the body’s immune response against the tumor.
Moreover, recombinant selenium not only helps with the direct attack on cancer but also plays a role in reactivating immune cells, such as dendritic cells. This process further strengthens the body’s defenses by reducing the number of immunosuppressive cells within tumor environments, allowing for a more effective overall treatment.
Overall, this innovative study sheds light on the potential of using selenium alongside probiotics to improve the outcomes of cancer therapies. Its findings suggest that there is a promising role for these combined therapies in clinical settings, advancing our ability to tackle cancer effectively.

We explored whether selenium levels in the blood could predict treatment outcomes for women undergoing neoadjuvant chemotherapy for breast cancer. By studying 329 women with HER2-positive or triple-negative breast cancer, we measured their selenium levels before starting treatment. Our findings suggest that higher selenium levels are linked to greater chances of achieving a pathological complete response (pCR). If further studies confirm this link, we could see research into selenium supplementation as a way to boost treatment effectiveness and survival rates.
