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.
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.
Through this innovative design, we observed that the zinc-manganese formulation not only displayed strong antimicrobial and antibiofilm properties but also played a role in promoting immune activation. This led to significant reductions in tumor growth and lung metastasis, alongside improved wound healing. The therapy activated key immune pathways, particularly the cGAS-STING pathway, which further bolstered the body’s ability to fight cancer cells.
Overall, the results suggest that zinc, paired with manganese, can provide an effective strategy for enhancing both local and systemic immune responses. This has promising implications for preventing cancer recurrence, particularly in challenging cases like TNBC, paving the way for potential new treatment approaches in oncology.
