Oncogenes and anti-oncogenes in tumorigenesis.
Recent advances have led to the identification of cellular genes which are involved in the initiation and progression of tumorigenesis. The proto-oncogenes, which normally participate in the regulation of cell proliferation and differentiation, can become oncogenes through alterations in the regulation of their expression and/or their coding sequences. Their contribution to the tumorigenic phen...
متن کاملOncogenes, anti-oncogenes and the immune response to cancer: a mathematical model.
We develop a mathematical model for the initial growth of a tumour after a mutation in which either an oncogene is expressed or an anti-oncogene (i.e. tumour suppressor gene) is lost. Our model incorporates mitotic control by several biochemicals, with quite different regulatory characteristics, and we consider mutations affecting the cellular response to these control mechanisms. Our mathemati...
متن کاملTransient oncogenes.
A given cancer is produced by a unique combination of genetic alterations that target specific genes, most often leading to activation of oncogenes and inactivation of tumor suppressor genes. Traditional oncogenes, such as RasV12, are involved in maintaining pro-survival and proliferation signals activated in the cell. Several evidences suggest that cancer cells are addicted to oncogenes and th...
متن کاملOncogenes and radiation carcinogenesis.
Current research indicates a role for several oncogenes in radiation-induced carcinogenesis in vivo and cell transformation in vitro. Certain oncogenes are probably also involved in some cases of human cancer caused by exposure to nonionizing radiation and may play a mechanistic role in the phenomenon of radioresistance seen in later stages of tumor progression. The mechanisms of oncogene activ...
متن کاملDarwin's gemmules and oncogenes.
In a recent issue of Annals of Oncology, Purushotham and Sullivan [1] reviewed Darwin’s legacy to cancer and medicine. However, they did not discuss Darwin’s Pangenesis, which provides a novel mechanism for cancerometastasis. Darwin habitually thought big. But the cell theory allowed him to think small. He wrote The Origin of Species without any reference to cellular structure in animals and pl...
