Psychoneuroimmunology: Diabetes and Cancer

58
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...

What is Cancer?

11.0K
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.
Although people have known about cancer for centuries, it was only in 1761 that Giovanni Morgagni of Padua performed a detailed autopsy of...

Cancers Originate from Somatic Mutations in a Single Cell

12.5K
Cancer arises from mutations in the critical genes that allow healthy cells to escape cell cycle regulation and acquire the ability to proliferate indefinitely. Though originating from a single mutation event in one of the originator cells, cancer progresses when the mutant cell lines continue to gain more and more mutations, and finally, become malignant. For example, chronic myelogenous leukemia (CML) develops initially as a non-lethal increase in white blood cells, which progressively...

Cancer Stem Cells and Tumor Maintenance

5.0K
Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.
Cancer stem cells are thought to originate from tissue-specific normal stem cells or progenitor cells. The normal stem cells usually reside in...

Cancer

49.3K
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

5.9K
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,...

Area of Science:

  • Neuroscience
  • Oncology
  • Cancer Biology

Background:

  • The nervous system is a master regulator of biological processes.
  • Emerging evidence implicates the nervous system in cancer initiation and progression.
  • Brain tumors, particularly gliomas, exhibit characteristics mirroring neural development.

Purpose of the Study:

  • To explore the role of neurodevelopmental pathways in brain tumor formation and progression.
  • To investigate the function of tumor microtubes in glioma invasion and network formation.
  • To understand how neuronal activity influences tumor growth and therapeutic resistance.

Main Methods:

  • Analysis of neurodevelopmental pathways in glioma models.
  • Characterization of tumor microtube formation and function.
  • Investigation of neuron-tumor cell interactions via glutamatergic synapses.

Main Results:

  • Gliomas form tumor microtubes, resembling neurites, guided by neurodevelopmental pathways.
  • Tumor microtubes facilitate invasion, proliferation, and the formation of a therapeutically resistant tumor network.
  • Neurons activate tumor cells through glutamatergic synapses, promoting invasion and growth.

Conclusions:

  • Brain tumors hijack neurodevelopmental processes for growth and invasion.
  • Tumor microtubes and neuron-glioma interactions represent novel therapeutic targets.
  • Understanding brain cancer neuroscience opens new avenues for anti-tumor treatments.
