Read this essay to learn about how oncogenes arise and proteins produced by oncogenes contribute to the development of cancer. 1. Essay on How Cellular Oncogenes Arise: Oncogenes can arise inside cells in two fundamentally different ways. One mechanism involves the participation of cancer viruses that introduce oncogenes into the cells they infect. The alternative, is based on a series [...]
In this article we will discuss about the diversity of retroviral oncogenes. Studies of other retroviruses of several different animal species (most notably the mouse, rat, chicken, and certain species of monkeys) soon led to the identification of other retroviral oncogenes. Over 20 different retroviral oncogene (Table 16.2) have been described to date, and more undoubtedly remain to be discovered. [...]
Genes that confer the ability to convert cells to a tumourigenic state are called oncogenes. Cancer cells are characterised by immortalization, transformation and metastasis. Oncogenes induce uncontrolled cell growth resulting in tumour, so it can be anticipated that the products of these genes would act by stimulating cell division in some manner. Now it is clear that the products of [...]
