mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

3.8K
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.
The mTOR pathway or the...

Tumor Progression02:07

Tumor Progression

6.4K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Adaptive Mechanisms in Cancer Cells02:53

Adaptive Mechanisms in Cancer Cells

5.9K
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,...

The Tumor Microenvironment02:17

The Tumor Microenvironment

6.7K
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...

Cancer Prevention02:59

Cancer Prevention

6.2K
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.

Interactions Between Signaling Pathways01:19

Interactions Between Signaling Pathways

6.4K
Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

Area of Science:

  • Oncology
  • Nutrition Science
  • Molecular Biology

Background:

  • Cancer is a leading global cause of death, with lifestyle factors like diet significantly influencing risk.
  • Unhealthy dietary patterns are major contributors to cancer development.
  • The precise role of specific dietary fatty acids in cancer risk and prognosis remains unclear.

Purpose of the Study:

  • To review epidemiological evidence linking different fatty acid classes to cancer risk.
  • To present preclinical data on how fatty acids affect tumor cells, progression, and metastasis.
  • To discuss the pro- and anti-inflammatory roles of fatty acids in cancer and explore clinical nutritional interventions.

Main Methods:

  • Systematic review of epidemiological studies on dietary fatty acid intake and cancer risk.
  • Analysis of preclinical research investigating the molecular mechanisms of fatty acids in cancer cells.
  • Evaluation of studies on the inflammatory effects of fatty acids in cancer progression.

Main Results:

  • Epidemiological data suggests associations between specific fatty acids and cancer risk.
  • Preclinical evidence indicates that fatty acids can modulate tumor cell behavior, impacting progression and metastasis.
  • Fatty acids exhibit both pro- and anti-inflammatory effects relevant to inflammation-induced cancer.

Conclusions:

  • Specific dietary fatty acids play a complex role in cancer development and progression.
  • Understanding these roles is crucial for developing targeted nutritional strategies.
  • Fatty acid-based nutritional interventions hold potential for cancer prevention and treatment.
