Scientists created tiny particles made from mushroom extract and zinc that can do two jobs at once: kill cancer cells and fight antibiotic-resistant bacteria. The particles were designed to target cancer cells specifically while leaving healthy cells alone. In laboratory tests, these particles successfully reduced cancer cell growth by turning off genes that help cancer spread and turning on genes that make cancer cells self-destruct. While this research is still in early stages and hasn’t been tested in humans yet, it shows promise as a potential new treatment approach that could address two major health problems simultaneously.
The Quick Take
- What they studied: Whether tiny particles made from mushroom extract and zinc coated with special molecules could kill cancer cells and fight bacteria at the same time
- Who participated: This was laboratory research using cancer cells (breast cancer cells called MDA-MB-231), normal healthy cells, and three types of bacteria. No human participants were involved in this study.
- Key finding: The particles successfully killed cancer cells while being gentle on normal cells, and they worked better against bacteria than regular zinc particles. The particles turned off genes that help cancer grow and turned on genes that make cancer cells die.
- What it means for you: This is very early-stage research that shows promise but is not ready for human use. It may eventually lead to new cancer and infection treatments, but many more studies are needed before doctors could use this approach with patients.
The Research Details
Researchers created tiny particles (called nanoparticles) using a green chemistry method, meaning they used natural mushroom extract instead of harsh chemicals. They started with zinc oxide and used Trametes versicolor mushroom extract to help form the particles and coat them. Then they added two special coatings: chitosan (a natural material from shellfish) to make the particles safer for the body, and folic acid (a B vitamin) to help the particles find and target cancer cells specifically.
They tested these particles in laboratory dishes containing cancer cells, normal healthy cells, and three different types of bacteria. They measured how well the particles killed cancer cells, whether they harmed normal cells, and how effectively they fought bacteria. They also looked at which genes were turned on or off inside the cancer cells to understand how the particles were working.
This research approach is important because it tries to solve two major health problems at once—cancer and antibiotic-resistant infections—with a single treatment. The use of green chemistry (natural mushroom extract instead of toxic chemicals) makes the particles potentially safer. The targeting system using folic acid is designed to deliver the treatment specifically to cancer cells, which could reduce side effects on healthy tissue.
This is laboratory research only, meaning it was done in test tubes and petri dishes, not in living organisms or humans. The researchers used multiple methods to confirm their particles were made correctly and worked as intended. However, because this hasn’t been tested in animals or humans yet, we don’t know if it will work the same way in a living body, where conditions are much more complex. The study is preliminary and represents early-stage research.
What the Results Show
The particles with all three components (zinc oxide, chitosan, and folic acid) were significantly better at killing cancer cells than particles without the special coatings. The particles successfully reduced cancer cell growth by interfering with the cancer cells’ ability to survive and reproduce.
Gene analysis showed that the particles turned off important cancer genes: CD44 and SOX2 (genes that help cancer cells stay alive and spread) and mTOR and β-catenin (genes that help cancer cells multiply). At the same time, the particles turned on Caspase 3, a gene that tells cancer cells to self-destruct.
Importantly, these same particles were gentle on normal, healthy cells, suggesting they could potentially be used without harming the body’s healthy tissue. This selective targeting is a major advantage over many current cancer treatments that damage both cancer and healthy cells.
The particles also showed strong antibacterial activity against three different types of bacteria, including antibiotic-resistant strains. The chitosan coating significantly improved the antibacterial effect compared to plain zinc particles. This dual functionality—fighting both cancer and bacteria—in a single particle is noteworthy because patients with cancer often develop serious infections that are difficult to treat.
This research builds on previous work showing that zinc oxide nanoparticles have antibacterial and anticancer properties. The innovation here is combining these properties with a targeting system (folic acid) and a biocompatible coating (chitosan) to make the particles work better and be safer. The use of mushroom extract for green synthesis is also a newer approach that reduces the use of toxic chemicals in manufacturing.
This study was only done in laboratory conditions with cells in dishes—not in living animals or humans. The results may not translate the same way in a real body where there are many more complex factors. The study doesn’t tell us about side effects, how long the particles stay in the body, or how they would be delivered to patients. There’s no information about the optimal dose or how often treatment would need to be given. Much more research, including animal studies and eventually human clinical trials, would be needed before this could become a real treatment option.
The Bottom Line
This research is too early-stage to make any clinical recommendations. It shows promise and suggests that further research is warranted, but it is not ready for human use. Anyone interested in new cancer treatments should continue working with their oncologist and wait for results from human clinical trials before considering experimental approaches.
Researchers in nanotechnology, cancer biology, and infectious disease should pay attention to this work as it may inspire future research directions. Cancer patients and people concerned about antibiotic-resistant infections may find this interesting as a potential future option, but it’s important to understand this is very preliminary. People should not seek out or attempt to use these particles outside of official clinical trials.
This research is at least 5-10 years away from potential human testing, and potentially much longer before it could become an approved treatment. The typical path involves animal studies (2-3 years), then human safety trials (2-3 years), then effectiveness trials (3-5 years), and finally regulatory approval. Even if everything goes well, this would not be available as a treatment for many years.
