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 examined the effects of gamma-tocopherol, a major form of vitamin E, on cancer treatment and prevention. This powerful antioxidant is noted for its ability to combat oxidative stress, which plays a significant role in the development and progression of various cancers.
In several studies, we observed that gamma-tocopherol not only neutralizes harmful reactive oxygen species but also exhibits anti-inflammatory properties. These characteristics help reduce chronic inflammation tied to cancer risks. Furthermore, it has shown the potential to inhibit tumor growth, induce cancer cell death, and restrict blood vessel formation that tumors require to grow.
Specifically, findings indicated that gamma-tocopherol is particularly effective in cancers such as prostate, lung, and colon. With promising results from both preclinical and clinical trials, there is a growing interest in how this natural compound can be beneficial in cancer management.
While we noted excellent tolerance at normal doses, it’s essential to consider careful monitoring at higher levels to avoid any adverse effects. Hence, we believe that ongoing research and advancements in drug delivery methods could further enhance its effectiveness.

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.

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.

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.

Selenium-Axitinib Combination in Cancer
We examined the combined effects of seleno-L-methionine (SLM), a selenium form, and axitinib for treating advanced clear cell renal cell carcinoma (ccRCC). Our study focused on patients who had already undergone prior treatments, seeking to uncover if SLM could enhance the effectiveness of axitinib.
Through a structured phase I clinical trial, we treated participants with escalating doses of SLM, starting from 2500 μg to 4000 μg. These doses were administrated orally, first twice a day and then alongside axitinib. An exciting aspect of our findings was the tolerance level of patients, with no dose-limiting toxicities reported at the highest dose.
Among the 27 patients who received 4000 μg of SLM, we observed notable results: a 55.6% overall response rate, with a median duration of response extending to 18.4 months. Additionally, median progression-free survival was documented at 14.8 months, and overall survival reached 19.6 months. These results suggest that SLM might enhance the therapeutic effect of axitinib while also contributing to better tumor vasculature and drug delivery.
In summary, our findings indicate that high doses of SLM, when combined with axitinib, are well tolerated and may improve treatment outcomes for patients with advanced ccRCC. However, further research is essential to fully understand its efficacy.
