Abstract:
Dicer has been well studied in cancer; however, deciphering its exact function in tumorigenesis continues to be a challenge. While partial suppression or truncation of Dicer promotes tumorigenesis, its complete deletion inhibits tumor growth. Here, we discuss this Dicer cancer conundrum in the context of its recently discovered role in the DNA damage response.
Insights
Dicer
Area of Science:
- Molecular biology
- Cancer research
- DNA damage response
Background:
- Dicer's role in cancer is complex and not fully understood.
- Partial Dicer suppression or truncation can promote tumor formation.
- Complete Dicer deletion, however, inhibits tumor growth.
Purpose of the Study:
- To explore the "Dicer cancer conundrum" by examining its role in the DNA damage response.
- To reconcile conflicting observations regarding Dicer's impact on tumorigenesis.
Main Methods:
- Literature review and synthesis of existing research on Dicer.
- Analysis of Dicer's involvement in DNA repair pathways.
- Discussion of experimental evidence linking Dicer to cancer progression and inhibition.
Main Results:
- Dicer's function in tumorigenesis is context-dependent.
- Dicer plays a critical role in the DNA damage response.
- The interplay between Dicer levels and DNA repair mechanisms influences tumor behavior.
Conclusions:
- Dicer's dual role in cancer, promoting or inhibiting tumor growth, can be explained by its function in DNA damage response.
- Understanding Dicer's involvement in DNA repair is key to resolving the cancer conundrum.

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...

When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...
