Summary
Cerium oxide nanoparticles (CONPs) show promise as a novel cancer therapy. These nanoparticles exhibit selective toxicity to cancer cells while protecting normal tissues, offering a potential nanomedicine for tumor treatment.
Area of Science:
- Nanomedicine
- Oncology
- Materials Science
Background:
- Nanomedicines are increasingly developed for tumor therapy.
- Cerium oxide nanoparticles (CONPs) possess diverse therapeutic properties.
- CONPs are being investigated as a potential anticancer agent.
Purpose of the Study:
- To review current research on CONPs for cancer therapy.
- To highlight the potential of CONPs as a novel nanomedicine.
- To discuss the differential cytotoxicity and antioxidant properties of CONPs.
Main Methods:
- Literature review of studies on CONPs in cancer therapy.
- Analysis of research data on CONP efficacy and safety.
- Synthesis of findings regarding CONPs' interaction with cancer cells and normal tissues.
Main Results:
- CONPs demonstrate toxicity to cancer cells.
- CONPs inhibit cancer cell invasion.
- CONPs sensitize cancer cells to chemotherapy and radiation therapy.
- CONPs exhibit minimal toxicity to normal tissues.
- CONPs possess antioxidant properties, protecting against reactive oxygen species.
Conclusions:
- CONPs show potential as a nanomedicine for cancer therapy due to selective cytotoxicity and antioxidant effects.
- Further research into CONPs as a novel therapeutic agent for cancer treatment is warranted.
- CONPs may offer a protective effect against reactive oxygen species generation in normal tissues.

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.

Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.

Mice have long served as models for studying human biology and pathology because of their phylogenetic and physiological similarity with humans. They are also easy to maintain and breed in the laboratory, and hence, many inbred strains are now available for research. Studies on mice have contributed immeasurably to our understanding of cancer biology.
The development of transgenic, knockout, and knock-in mice has led to an exponential increase in their use as model organisms in research,...
