Obesity01:24

Obesity

1.5K
The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...

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 Progression

3.6K
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

863
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...

Cause and Effect01:53

Cause and Effect

10.5K
While variables are sometimes correlated because one does cause the other, it could also be that some other factor, a confounding variable, is actually causing the systematic movement in our variables of interest. For instance, as sales in ice cream increase, so does the overall rate of crime. Is it possible that indulging in your favorite flavor of ice cream could send you on a crime spree? Or, after committing crime do you think you might decide to treat yourself to a cone?

Area of Science:

  • Oncology
  • Endocrinology
  • Metabolism

Background:

  • Adiposity is a known risk factor for type 2 diabetes and cardiovascular disease.
  • Emerging evidence links excess body weight to several cancers, including gastrointestinal, endometrial, esophageal adenocarcinoma, colorectal, postmenopausal breast, prostate, and renal malignancies.

Purpose of the Study:

  • To explore the association between adiposity and cancer development.
  • To investigate the underlying cellular and molecular mechanisms linking excess body weight to malignancy.

Main Methods:

  • This study reviews hypothesized mechanisms.
  • The review focuses on factors such as insulin, insulin-like growth factors, sex hormones, adipocytokines, inflammatory cytokines, and hypoxia.

Main Results:

  • Adiposity is associated with an increased risk of developing various cancers.
  • Hypothesized mechanisms include hormonal imbalances, chronic inflammation, and altered cellular signaling pathways.

Conclusions:

  • While the link between adiposity and cancer is evident, the precise mechanisms require further elucidation.
  • Future research will focus on understanding the cellular and molecular pathways involved in adiposity-associated tumorigenesis.
