Summary
Antioxidants may promote cancer by acting as diverse messengers in cancer cells, not prevent it. Understanding redox biology is key to developing effective cancer therapies.
Area of Science:
- Redox biology
- Cancer research
- Biochemistry
Background:
- Historically, antioxidants were considered chemopreventive.
- Emerging evidence suggests antioxidants may support tumor growth (neoplasia).
- Reactive oxygen species (ROS) function as diverse secondary messengers in cancer cells.
Purpose of the Study:
- To investigate the dual role of antioxidants in cancer.
- To understand the complex functions of ROS in neoplastic cells.
- To guide the development of novel cancer therapies targeting redox alterations.
Main Methods:
- Application of biophysical and biochemical approaches.
- Defining redox dynamics in cancer cells.
- Elucidating specific oxidative modifications in cancer versus normal cells.
Main Results:
- Reactive oxygen species (ROS) are not a single entity but diverse messengers.
- Global increases in ROS may not be therapeutically beneficial.
- Specific oxidative modifications differ between cancer and normal cells.
Conclusions:
- A nuanced understanding of redox biology is crucial for cancer treatment.
- Targeting specific redox pathways, rather than global ROS levels, is a promising therapeutic strategy.
- Further research into redox dynamics is imperative for defeating cancer.

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.

6.5K
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.

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.

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...

5.0K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

02:59Cancer Prevention
8.4K
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.
