Tomorrow is the day where I have to sit for a test called Oncology. And the section tested would involve all the cancer pathways and the dysregulation of all these pathways lead to cancer formation (carcinogenesis).
So here’s an overview of the cancer pathways:
1. The AKT/PKB Pathway
This pathway is involved in the cell proliferation and growth.
2. Cyclins and Cell Cycle Regulation
This pathway is a continuation of previous pathway. This pathway regulates DNA replication and cell proliferation.
4. The Famous p53 Pathway – One of the most important cell guardian
This pathway makes sure that everything is right. Not too much of proliferation, induce repair mechanisms and apoptosis in cases of DNA damage. It basically protects a cell from going crazy. Mutation in gene expressing this p53 protein eventually leads to cancer formation, no doubt.
4. Epidermal Growth Factor (EGF) Pathway
Part of the pathways was learnt, and again, they all regulate cell proliferation and growth.
5. (Summary of) Molecular Mechanisms of Cancer Pathway
I think this is the most complex diagram ever constructed. This is how complex cancer is.
6. (Another Summary of) Pathways in Human Cancer
This is exactly what I’m studying at this moment. This PDF is available at http://www.cellsignal.com/about/marketing/pdfs/cancer_poster.pdf
As you can see, the pathways are driving everyone crazy, and these are all normal cell processes. Without them, we cannot survive. Yet, dysregulation of these pathways lead to cancer formation. Why dysregulation occurs? Too many factors already, which include chemical and physical exposures, cellular processes etc. Most frequently, food is one of the main causes of cancer. So, YOU ARE WHAT YOU EAT.
By the way, too much of stress do induce cancer formation… and I’m a bit stressed out… Hope that I don’t get cancer because of this… CHOY!!!
