Summary
The oral bacterium Fusobacterium nucleatum promotes various cancers by enhancing tumor growth, immune evasion, and treatment resistance. Understanding its tumor colonization mechanisms is key for new cancer therapies.
Area of Science:
- Oncology
- Microbiology
- Immunology
Background:
- Fusobacterium nucleatum is an oral bacterium increasingly linked to diverse cancer types.
- This pathobiont contributes to tumor progression through multiple mechanisms.
Purpose of the Study:
- This review focuses on the mechanisms of tumor-specific colonization by Fusobacterium nucleatum.
- Understanding these mechanisms can inform novel cancer detection and treatment strategies.
Main Methods:
- This review synthesizes existing research on Fusobacterium nucleatum's role in cancer.
- It analyzes the molecular and cellular mechanisms of tumor tropism and promotion by this bacterium.
Main Results:
- Fusobacterium nucleatum enhances tumor cell proliferation and fosters a pro-tumorigenic immune microenvironment.
- It also induces chemoresistance and activates immune checkpoints, contributing to tumor progression.
Conclusions:
- Fusobacterium nucleatum exhibits specific tropism for tumors, driving their growth and therapeutic resistance.
- Elucidating these interactions offers potential for developing new anti-cancer strategies targeting this oral pathobiont.

6.0K
Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...

02:55The Nucleolus
9.3K
The nucleolus is the most prominent substructure of the nucleus. When it was first discovered, it was considered to be an isolated organelle that forms fibrils and granules. In 1931, the relationship between the nucleolus and chromosomes was first described by Heitz. He observed that the appearance and size of nucleolus varies depending on the stage of the cell cycle. He also noticed constricted regions on different chromosomes clustered together at definite cell cycle stages. These regions,...

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.

02:12What is Cancer?
11.4K
Cells and tissues must meticulously coordinate their activities for the normal functioning of the human body. Therefore, they exhibit socially responsible behavior - resting, growing, dividing, differentiating, or dying - for the organism’s benefit. Cancer arises when cells divide uncontrollably and invade other tissues or organs.

02:17The Tumor Microenvironment
6.8K
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

5.5K
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
