Abstract:
It has become clear that tumorigenesis results from much more than just the activation of an oncogene and/or the inactivation of a tumor-suppressor gene, and that the cancer cell genome contains many more alterations than can be specifically targeted at once. This observation has led our group to a search for alternative ways to kill cancer cells (while sparing normal cells) by focusing on properties unique to the former. We have identified four approaches with the potential to generate new anticancer therapies: combatting the tactics by which cancers evade antitumor immune responses, targeting metabolic adaptations that tumor cells use to survive conditions that would kill normal cells, manipulating a cancer cell's response to excessive oxidative stress, and exploiting aneuploidy. This review describes our progress to date on these fronts.
Insights
Cancer cells possess unique vulnerabilities beyond simple gene mutations. Researchers are exploring novel anticancer therapies by targeting immune evasion, metabolic adaptations, oxidative stress, and aneuploidy to selectively eliminate tumors.
Area of Science:
- Oncology
- Cancer Biology
- Immunotherapy
Background:
- Tumorigenesis involves complex genetic alterations beyond oncogene activation or tumor-suppressor gene inactivation.
- The multitude of genomic alterations in cancer cells presents a challenge for targeted therapies.
- Identifying unique cancer cell properties is crucial for developing selective anticancer strategies.
Purpose of the Study:
- To explore alternative therapeutic strategies for eliminating cancer cells while sparing normal cells.
- To focus on vulnerabilities unique to cancer cells for novel treatment development.
- To review progress on four distinct approaches to cancer therapy.
Main Methods:
- Investigating mechanisms of cancer immune evasion.
- Analyzing metabolic adaptations in tumor cells.
- Exploring manipulation of cancer cell responses to oxidative stress.
- Exploiting the role of aneuploidy in cancer.
Main Results:
- Four promising approaches for novel anticancer therapies have been identified.
- Progress has been made in understanding and targeting cancer's unique properties.
- The identified strategies aim for selective cancer cell killing.
Conclusions:
- Novel anticancer therapies can be developed by targeting cancer-specific vulnerabilities.
- The four explored avenues offer potential for innovative cancer treatment.
- Further research in these areas may lead to more effective and less toxic cancer therapies.

Cancer Therapies
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.
