|February 26, 2011
Summary
Oncogene expression triggers anti-oncogenic pathways via oncogenic stress. A new study reveals the Jnk pathway is crucial for activating p53 in response to K-Ras and Neu oncogene expression.
Area of Science:
- Cellular biology
- Cancer research
- Molecular oncology
Background:
- Oncogene activation in normal cells initiates anti-oncogenic pathways, a process termed oncogenic stress.
- The precise molecular mechanisms underlying oncogenic stress remain incompletely understood.
Discussion:
- The study investigates the role of the Jnk pathway in response to oncogene activation.
- It examines how oncogenic stress influences the p53 pathway.
- The findings link specific oncogenes (K-Ras, Neu) to Jnk and p53 activation.
Key Insights:
- The Jnk pathway is implicated in p53 activation during oncogenic stress.
- This signaling cascade is activated by both K-Ras and Neu oncogene expression.
- Provides a mechanistic link between oncogenes and the p53 tumor suppressor.
Outlook:
- Further research can explore therapeutic strategies targeting the Jnk-p53 axis.
- Understanding this pathway could lead to novel cancer treatments.
- Investigating other oncogenes and their impact on this stress response is warranted.

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
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.

Adaptive Mechanisms in Cancer Cells
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,...

Cancer-Critical Genes I: Proto-oncogenes
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.
