Download file to see previous pages For a long period, it has become clear that cancer frequently impinges on citizens who are above 50 years. Although the youthful populace also gets afflicted with such illnesses, the majority of populace suffering such ailments as cancer is the old populace (Hobson, 2009). Through the following observation, researchers have started to investigate the affiliation between biological procedures that direct disease and aging processes. Researchers have to this point been able to determine the connection between the two. Researchers have substantiated two ways of viewing the correlation between cancer and age. According to the findings provided, are that the forces that cause damage to human genes may be similar to the forces that compel both cancer and aging (Hobson, 2009). Therefore, this suggests that the processes guard against cancer, the genome and permanence. However, the second reason seems to be a bit complex concerning the correlation among the two. Naturally occurring tumor suppressor molecules prevent the cells from reproducing or regenerating sporadically. The tumor suppressor cell provokes the fatality of the cells through a procedure regarded as apoptosis or it can shut down the cell’s ability to replicate. These two progressions produced by the suppressor molecules serve to protect the people during their reproductive periods. Therefore, as the populace gets older, the molecules abilities to guard the body through the two methods reduce. For this reason, the body becomes vulnerable to cancer attacks justifying the statement that the cancer cases are more extensive in the old people. For the young generation, the susceptibility is markedly reduced through the action of the suppressor molecules. The older people experience corporal changes that augment the probability of disease and disability and which interfere with the body’s ability to withstand cancer threats. Cancer occurs mainly because of any transformations or alterations on the oncogenes, tumor suppressor molecules and microRNA genetic material (Croce, 2008, 502). These modifications are usually somatic procedures, even though origin transmutation can dispose an individual to genetic or ancestral cancer. In cancer, a single alteration may not be sufficient to initiate cancer instead, cancer development is a multistep progression with alterations occurring in oncogenes (Croce, 2008, 502). Oncogenes are proteins that predetermine for the control of cell propagation, apoptosis or even the two processes. These genes are activated by structural transformations that originate from mutations or amplification (Croce, 2008, 503). Chromosomal reorganization, transmutations and gene extension, help in activation of oncogenes presenting an enlargement benefit or amplified continued existence of cells bearing such variations. In cases where, the oncogenes are activated by mutations, the preset protein is altered structurally in ways that allow for its transforming action. Myc is a replication regulator and its genes are usually translocated from the original chromosome to another chromosome. Chromosomal translocations help in joining the cellular oncogene together with immunoglobin that are believed to be vital, in the initiation of the oncogenic progressions in the developments of certain cell types. The translocation can be considered essential in essence, that it helps in the study of the means, heredity and biological outcomes of the translocations. ...Download file to see next pagesRead More

How Cell Phones Can Cause Cancer for Users

...? English How Cell Phones Cause Cancer for Users Electromagnetic Radiation (EMR) is a form of energy absorbed and emitted by charged particles with wave-like oscillation behavior in a space. Depending on charging ability of EMR, electromagnetic radiation can also be categorized as ionizing and non-ionizing EMR (Weinberg 15). Ionizing EMR include cosmic, radon, and x-rays, while non-ionizing EMR include radiofrequency and very low-frequency radiations. Weinberg (p. 16) warns that radiofrequency energy is capable deeply penetrating the body of human beings without any external detection. Cell phones are examples of gadgets that emit radiofrequency energy. This paper, in effect, explains how cell phones cause cancer to their users... ....

Cancer stem cell

...?Cancer Stem Cell Bapat (2008, p.6) s that, for over three decades, researchers have been able to develop more effective way of treating cancers such as testicular cancer, child Leukemia, and Hodgkin’s disease. In addition, death rates resulting from cancers such as the prostate and breast cancers have also reduced significantly over the past few years. The reduction is attributed to advances in early diagnoses and prevention of disease. This is because there have been an advocacy encouraging people to go for testing in order to be able to treat these cancers at their early stages. Nevertheless, research shows that the...

Metabolite Processing

... Introduction Normally, cancer cells requires more energy and metabolites for the cell growth and proliferation. Unlike the normal cells, the growth rates of the cancer cells are very rapid and uncontrollable. They take up the nutrients excessively and shunt metabolite pathways supporting the growth. The alteration in the metabolic pathway and the mutation in the genes cause the rapid proliferation of the cancer cells. This type of variation in the growth is termed as metabolic...

B-cell Cancer and Different Stages of B-lymphocyte Development

...B-cell Cancer and Different Stages of B-lymphocyte Development B-Cells The human body is made up of countless number of cells of different types. Cells have specialized jobs according to their source such as skin, heart, lung, blood etc. Genes which are located in the cell nucleus control cell division and cell death. Genes function like an instruction manual telling the cell what proteins to make. These proteins in turn control the behaviour of the cell. Just like any other cell, the human body makes millions of various types of B cells everyday and each type has a unique receptor protein on its membrane that will bind to one particular antigen. B cells are white blood cells (lymphocytes) that play a vital role in the production... between...

Current methods for Cancer Stem Cell characterisation and isolation

...Non- adherent spheres formation Method background and overview CD133+ cells found in brain tumors are found to be responsible for the generation of neurospheres [Singh 2003]. Following this observation, purified CSCs in cultures were also implicated in the formation of spheres. Such CSCs were demonstrated in breast [Al-Hajj et. al. 2003], colon [Ricci-Vitiani et. al. 2007], melanomas [Fang et. al. 2005], prostate [Patrawala et. al. 2006], and pancreas [Gou et. al. 2007]. This characteristic property of purified CSCs is being exploited for their enrichment from tumor cultures. The culturing of cells from breast cancer in low adherent conditions, which promote sphere formation, has...

Mitosis & Cell Cycle: Cancer Treatments

...Mitosis and Cell Cycle: Cancer Treatments Mitosis and Cell Cycle: Cancer Treatments Introduction Cancer refers to uncontrolled growth of abnormal cells in the body. It grows of normal cells whereby cells divide quickly and fail to undergo apoptosis (programmed cell death). This implies that cancerous cell evade cell control systems in the body. Uncontrolled cell division leads to multiplication of the cells of the body. Cancer can affect in any part of body tissues and organs. These...
