Psychoneuroimmunology: Diabetes and Cancer

27
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...

Cancer Cell Migration through Invadopodia

2.3K
Invadosome is a broad category of cell surface structures with proteolytic activity that  degrades the extracellular matrix (ECM). Invadosomes are present in normal cell types, including macrophages, endothelial cells, and neurons, as well as tumor cells. Although the macrophage podosomes and tumor cell invadopodia are classified as invadosomes, they have different structures, molecular pathways, and functions. Podosomes are short structures that last for a few minutes. However,...

Regulation of Angiogenesis and Blood Supply

2.5K
Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits.  Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...

Cancer

48.2K
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.

Adaptive Mechanisms in Cancer Cells02:53

Adaptive Mechanisms in Cancer Cells

5.7K
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,...

Area of Science:

  • Oncology
  • Immunology
  • Cardiovascular Research

Background:

  • Vascular inflammation is crucial for cancer progression and metastasis.
  • Tumor endothelial cells (TECs) upregulate adhesion molecules and cytokines in response to various stimuli, aiding tumor cell adhesion and immune evasion.

Purpose of the Study:

  • To review key mechanisms of vascular inflammation in cancer metastasis.
  • To explore emerging therapeutic strategies targeting vascular inflammation.

Main Methods:

  • Review of literature on vascular inflammation triggers.
  • Analysis of preclinical data on novel therapeutic interventions.

Main Results:

  • Identified Streptococcus mutans, oxLDL/LOX-1 axis, and chemotherapy as key inflammatory triggers.
  • These triggers converge to establish a pre-metastatic niche.
  • Microbiota modulation, metabolic targeting, and low-dose metronomic chemotherapy show promise in preclinical models.

Conclusions:

  • Targeting vascular inflammation offers a novel therapeutic strategy against metastasis and cardiovascular events.
  • Further research is needed to validate biomarkers and optimize clinical applications.
