Detailed focus question: What is the process of self-renewal and duplication in breast cancer stem cells through E113, the Wnt-beta catenin signaling pathways and the tumor regulator p53? I. Introduction: To explain the cellular and molecular features of my focus question I will provide background on cancer stem cells, some of the various signaling pathways and breast cancer specifically. A. Cancer Stem Cells (Tumor-initiating cells) 1. Basic Features: Have the capacity to self renew and the…

It was recorded that 12 out of 35 patients, suffered from extrahepatic tumour. This was revealed by PET/CT combined and by CT scan single-handedly. The extrahepatic tumours in two of the patients were not detected by PET and PET/CT; those were recorded to have node of 2 –cm lymph in the hepatoduodenal ligament. It is furthermore, true that both forms of the scans (CT and PET/CT) reported extrahepatic tumour in patients that did not have it at all. The CT scan reported it in 3 out of 23 patients,…

Tobacco smoke contains more than 7,000 chemicals, some of which contribute to tobacco dependence.[1] However, nicotine is the major chemical component in tobacco that is responsible for addiction.[2] Nicotine can be readily absorbed through the mucosa of the mouth, nose, and lungs. It can also be readily absorbed through the skin.[2] With tobacco smoking, nicotine reaches the brain in 10 seconds.[1] Once in the brain, nicotine stimulates the release of the neurotransmitter dopamine, which is…

The Therac-25 machine was a third-generation machine produced by the company AECL which specialized in manufacturing machines which provided radiation therapy to cancer patients. This machine accomplished this by emitting a beam of electrons or x-rays to the cancerous area. This amount of radiation interferes with the cancerous tissue’s ability to grow by disabling the genetic material in the cell. However, since cancerous cells are not the only cells in the body that grow very quickly, skin and…

Cancer can start almost anywhere in the human body, it happens when the cells function irregularly and turn itself into the malignant neoplasm. From the biological perspective, human body mechanism will automatically produce the new cells from old cell when an old cell becomes obsolete. In other word, the old cell will die by dividing itself into two new cells. Furthermore, the new cells will take over previous cell’s position to make sure the human body function regularly, and this processing…

Genetic engineering is known for it 's potential of saving lives in situations doctors have no control over and with recent developments in has made its way toward saving children before birth. It also allows people a cost effective way to be able to help increase a child 's circumstances at birth while they are still an embryo but at what cost. Just like any new technological breakthrough there are people who are taking advantage of this new technology that should require the government to…

Chemoradiotherapy: harmful or beneficial? There are many treatment suggestions for those who have been diagnosed for cancer. Some could be chemotherapy, radiation, or both, which is chemoradiotherapy. While studying and researching the affect these treatments have on cancerous cells and tumors, a major question is asked about the future health of the cancer patients. Is the combination of chemotherapy and radiation, also known as chemoradiotherapy, more beneficial or harmful to patients? Some…

of ovarian and testicular cancer was given in 1978. Currently in cancer treatments, Cisplatin is one of the three greatest consumed antitumor drugs in the world. However like any other drugs Cisplatin has its own advantage and disadvantages. One of the main disadvantages is sever toxicity such as neurotoxicity, ototoxicity…

Biology 1A The Biology of Disease Thyroid Cancer Cancer is a disease that plagues many people word-wide and can prove to be extremely deadly with a high mortality rate, or not as much so with a high survival rate. This is because some cancers prove to be more difficult to manage and remove while others do not require to be removed and may just cause minor complications. Thyroid cancer happens to have characteristics from both these types of cancers; it can be subtle and cured easily if caught…
