Cancer Prevention02:59

Cancer Prevention

6.3K
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.

Cancer

49.8K
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.

Psychoneuroimmunology: Diabetes and Cancer

Chronic stress has been linked to both the onset and progression of serious health conditions, including Type 2 diabetes and cancer. Type 2 diabetes, a widespread chronic illness, is closely associated with obesity and insulin resistance, both of which often worsen under stress. Studies indicate that men experiencing high levels of chronic stress face a 45% higher risk of developing diabetes compared to those with minimal stress. Stress triggers physiological responses that elevate blood...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

3.9K
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...

Cancer Survival Analysis01:21

Cancer Survival Analysis

458
Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...

Cancer-Critical Genes I: Proto-oncogenes01:33

Cancer-Critical Genes I: Proto-oncogenes

9.2K
Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
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...

Area of Science:

  • Oncology
  • Cellular Metabolism
  • Cancer Biology

Background:

  • Iron is vital for DNA synthesis, repair, and cellular metabolism.
  • Cancer cells exhibit increased iron requirements compared to normal cells.
  • Tumor iron dysregulation involves import/export changes and altered gene expression.

Purpose of the Study:

  • To explore the role of iron in cancer cell proliferation and survival.
  • To investigate the impact of tumor microenvironment on iron metabolism.
  • To highlight therapeutic opportunities targeting cancer cell iron dependence.

Main Methods:

  • Review of existing literature on iron metabolism in cancer.
  • Analysis of gene expression signatures related to iron.
  • Examination of therapeutic strategies targeting iron pathways.

Main Results:

  • Cancer cells upregulate iron import and downregulate export.
  • Tumor microenvironment cells modulate cancer iron status.
  • Dietary heme iron may influence cancer risk, modulated by immune cell iron interactions.

Conclusions:

  • Cancer cell iron dependence presents therapeutic vulnerabilities.
  • Targeting iron uptake and inducing ferroptosis are promising strategies.
  • Iron recycling mechanisms, like in KRAS-mutated pancreatic cancer, are key for drug development.
