Vitamin C enhances immune response
We delved into how vitamin C might influence cancer treatment, focusing on its effects on the immune system. Our findings revealed that vitamin C directly modifies certain proteins, leading to a new type of protein change called vitcylation. This process specifically affects a protein known as STAT1.

By modifying STAT1, vitamin C enhances its ability to signal for immune responses. We found that this modification occurs in both controlled environments and living cells, depending on factors like dosage and acidity. As a result of vitcylation, the action of STAT1 is improved, which activates important immune responses in tumor cells and boosts the expression of molecules that help the immune system recognize and attack cancer cells.

Interestingly, this research sheds light on the potential of vitamin C as a treatment that not only affects cancer directly but also empowers the body’s own defenses. These insights pave the way for new approaches to cancer therapy that leverage the immune system in conjunction with vitamin C.

Zinc's role in cancer immunity
We explored how zinc levels impact cancer cells and immune function, particularly focusing on macrophages, which are crucial for our body’s defense against tumors. Our research revealed that cancer cells often have decreased expression of specific genes tied to immune response, and this links to resistance against therapies designed to unblock immune checkpoints.

By upregulating a zinc importer known as SLC39A9, these cancer cells manage to hoard zinc for themselves, leaving the surrounding tumor microenvironment (TME) depleted of this vital nutrient. This competition for zinc results in macrophages becoming zinc-starved, which diminishes their ability to perform essential tasks like engulfing and destroying cancer cells.

Interestingly, we found that when we replenished zinc levels in the TME—through a dietary intervention—these macrophages could regain their pro-phagocytic function. This change significantly improved the response of certain tumors to immunotherapy treatments. Notably, T cells weren’t required for this transformation, indicating that macrophages alone play a pivotal role.

Our results are clinically relevant, showing that cancer patients with reduced zinc levels in their body tend to experience worse outcomes. Overall, we identified a new mechanism by which cancer cells can disrupt immune function, highlighting zinc’s critical role in both tumor environments and immunotherapy effectiveness.

Elderberry protein's anticancer potential
We focused on a newly identified protein called pebulin, derived from dwarf elder, and examined its potential anticancer effects. The protein was successfully produced in E. coli and purified for further testing.

Our tests revealed that pebulin is not only capable of agglutinating red blood cells from all human blood types but also has significant inhibitory effects on cancer cell lines like MCF-7 and HT-29. This means that pebulin could slow down the growth of these cancer cells, a promising outcome we found particularly exciting.

Additionally, we noted that pebulin demonstrated effectiveness against certain plant fungi, showcasing its versatile bioactivity. The study suggests that pebulin may offer a new avenue for cancer treatment, particularly considering its impact on both cancer cells and fungi.

Zinc enhances TNBC treatment efficacy
We developed an innovative treatment approach for triple-negative breast cancer (TNBC) using zinc-copper bimetallic nanoplatforms. These specially designed nanostructures help promote a type of cell death known as cuproptosis while also boosting the immune system's response to tumors. By leveraging these properties, we aimed to find a way to make existing immune therapies more effective against TNBC, which is notoriously difficult to treat.

The mechanism behind this approach involves the nanoplatforms releasing both zinc and copper ions within the acidic environment of tumors. This releases hydroxyl radicals and impacts certain proteins in cancer cells, disrupting their function and leading to cell death. Additionally, the released mitochondrial DNA works alongside zinc to activate pathways that boost the immune response, ultimately helping to improve the effectiveness of anti-PD-L1 treatments.

Furthermore, we observed that using a near-infrared laser significantly enhances these effects. Together, the combination of our nanoplatforms and immune therapies results in a powerful treatment strategy, showcasing zinc's potential role in fighting TNBC.

Overall, our findings suggest a promising new direction for TNBC therapy by uniting the benefits of cuproptosis, immune activation, and laser therapy.

Zinc works alongside nanomedicine
We investigated an innovative approach to cancer treatment by using a special nanomedicine that combines zinc with a compound called 2,5-dihydroxyterephthalic acid (DHT). This combination aims to target the cancer stem-like cells, which are known for their role in tumor recurrence and spread.

The nanomedicine works by effectively pulling in the cancer's own iron and releasing zinc. This process not only helps in reducing the iron levels in tumors but also enhances the production of reactive oxygen species (ROS), which are crucial for damaging cancer cells. By lowering iron, we push the cancer stem cells towards differentiation, while the increased ROS levels help trigger cell death.

What's especially compelling about our findings is that this treatment appears to tackle both aggressive cancer stem-like cells and the bulk of the tumor, showing promise in preventing cancer growth, recurrence, and metastasis. The results have been especially notable in cases of triple-negative breast tumors, providing an exciting potential path for future cancer therapies that take advantage of these properties.
