Researchers spent years finding out the roots of this disease and to discover the best possible remedies for curing this fatal pathology. Cancer is a challenge for even the first world countries. It is an unavoidable war opponent which seems to be standing in the way of the scientists and the afflicted people. Even President Nixon attempted a war on cancer and spent more than $ 5 billion to America’s National Cancer Institue (NCI), annually to counter this life taking disease. This is owing to the fact that the disease is life hampering and affects the quality of life of the patients affected. Professionals are now considering involving physicists in the field of exploration because they seem to have given up on the possibility of finding the exact cause of cancer. This finding of the most appropriate cause for cancer will assist in reaching to the best conclusion for the treatment modalities of cancer and it will serve to be a breakthrough in the field of medicine (Davies 2012). The mechanism of cancerous disease is very complicated since alterations of metabolism are a very common manifestation of these oncological changes in the cells. These manifestations are still not obvious and significant for benign tumors and for tumors that are not of very high grade. Cancer cells heavily rely on high glucose dosage owing to their increased energy needs and this increased energy demand aids in the detection of these cancerous cells. Based on research, tumor is detected according to its phenotype. The metabolic phenotype of this cell is monitored by the changes in the genetic structure of the cells as well as the changes that are taking place outside the cancerous cells in the normal tissues. It was deduced that the changes in the metabolism are a very significant feature of the cancer cells and they form the basis for the rapid multiplication of these cells. Cancerous signals are transmitted to these cells which result in the cascade of duplication. The target of these biologists and researches is to find a way to slow down the metabolism of the tumor “progression” so as to enhance the treatment of cancer and produce excellent results (Cairns et al. 2011). In order to understand the complex biology of cancer, it is highly essential to recognize the “hallmarks of cancers” that help identify the traits that initiate and speed up the cancer cells to survive. These hallmarks include cellular energy metabolism through a process which results in the growth of cells, eventually taking over the normal processes that occur in the human body leading to increased operations in other adjacent cells as well and resulting in a cancerous growth. On the other hand, another hallmark that enables the cancer cells to replicate is the suppression of the immune system caused by these cells. Both these capabilities of the cancer cells speed up the cancerous growth in the body. Recent studies have also shown that a tumor cell is more complex than a normal healthy tissue (Hanahan & Weinberg 2011). Cancer is a growing concern for public as well. People have become superstitious about its whereabouts. But Davies and his fellow researchers have come to believe and promote that cancer is like an aging agent to which everyone conforms to at one ...Download file to see next pagesRead More

Developmental Biology associated with uncontrolled cellular proliferation and reduced sensitivity to apoptosis-inducing agents. Both of these lead to cancers and aging and ability to control the regulation of this pathway can lead to a therapeutic breakthrough in the management of diseases associated with aging (Steelman, Chappell and Abrams). The role of sirtuin gene (SIRT1) is being seen as a potential breakthrough in the prevention of diseases related to aging. Sirtuins are proteins that are linked to mitochondrial biology which is said to be a key player in the process of aging. In a study conducted in order to find out this link, the conclusion drawn was that while science is still a long way from using sirtuins to...

...?Cancer Cancer cells differ greatly from normal healthy cells. While healthy cells stay where they are and only go to parts of the body where they are required, cancer cells completely ignore this rule and go wherever they please. In this way, they spread to various parts of the body, circulating the disease. Another way that healthy cells differ from cancer cells is that healthy white blood cells can detect damaged cells, such as viruses, and attack them, stopping them before they spread the virus to the rest of the body. Cancer cells, however, can pass through this system without being detected, which means that the immune system is not notified to...

Cancer and Biology

...? Cancer and biology Cancer and biology Cancer describes diseases whose growth of cells is beyond control. There are numerous categories of cancer with each category exuding distinct tendencies based on areas initially affected. Scientists report that more than one hundred cancer types exist in the world today. The presence of cancer in the body leads to the damage of the body cells that undergo unrestrained division to form tumors. Consequently, tumors correspond to lumps of tissue. It is only in the case of leukemia that cancer does not allow division of the cell as the normal function of the blood. The growth of the tumors leads to the interference of circulatory, digestive and the nervous systems. Tumors also release hormones... on the...

...Biology What is Spina bifida? Why spina bifida is considered as a multifactorial trait? Spina bifida is a condition of the spinal cord in which there is incomplete closure of the neural tube in the embryo. This closure actually occurs at the 28th day of embryonic development. Hence this disorder is known as a neural tube defect, in which the spinal cord does not completely close because of the decreased development of the vertebral column. Spina bifida is considered to be a multifactorial trait because this disorder is led to by both genetic and the environmental factors. The environmental factor is considered to play a role in the expression of the disorder. The genetic component occurs because of the combined effect of...

...on their experiment with rats. Despite his revelations, the government still favored large institutions that produce and distribute these goods (Lilliston, 2013). This is a very relevant issue in the field of biology and other relevant fields such as botany, nutrition, health and others. I believe that the government should keep watch of this concern. It is not enough for them to create one click solutions without knowing the consequences. Government funds must be intended for organic farming instead of production of GA foods. Information drives must be done to the public regarding GA foods and how they affect the bodies. Until now they are sold in the market and even priced lower that organically produced goods....

Cell biology the cell and the process of transfection introduces into a cell an entirely new gene. To discover which cells are expressing a certain transcript of RNA, cell biologists use in situ hybridization. During cell biology, purification of cells can be accomplished using techniques such as flow cytometry, cell fractionation, immunoprecipitation, and so on (Pollard and William, 418). Some of the processes of the cell commonly studied by cell biologists include active and passive transport, adhesion, cell movement, DNA repair (cell death and senescence), gene expression, metabolism, cell signaling, division and autophagy. Knowledge of cell biology is useful in fields such as cancer research...
