We have introduced viral oncogenes into human mammary epithelial cells through the use of murine retroviruses. A continuous cell line (184A1N4) derived from benzo(a)pyrene treatment of normal breast epithelial cells was used as a recipient for the ras, mos, and T-antigen oncogenes. Each of these oncogenes enabled the 184A1N4 cells to grow in a selective medium, thus demonstrating the potential ...
Background Cancer is a genetic disease and mainly arises due to a number of reasons include activation of onco-genes, malfunction of tumor suppressor genes or mutagenesis due to external factors. Methods This article was written from the data collected from PubMed, Nature, Science Direct, Springer and Elsevier groups of journals. Results Oncogenes are deregulated form of normal proto-oncoge...
Abstract A cancer dogma states that inactivation of oncogene(s) can cause cancer remission, implying that oncogenes are the Achilles' heel of cancers. This current model of cancer has kept oncogenes firmly in focus as therapeutic targets and is in agreement with the fact that in human cancers all cancerous cells, with independence of the cellular heterogeneity existing within the tumour, carry ...
The concomitant expression of certain oncogenes can transform normal diploid rodent cells into transplantable tumorigenic cells. The mechanism by which these oncogenes collaborate is unclear. Recent findings (M. Oshimura, T. M. Gilmer, and J. C. Barrett, Nature [London] 316:636-639, 1985) raise the possibility that karyotypic changes, including monosomy for chromosome 15, are required to induce...
The results of recent studies on the molecular biology of cancer suggest the abnormal expression of cellular proto-oncogenes in the process of carcinogenesis [1]. The activation of proto-oncogenes, i.e., their conversion into cellular oncogenes, is associated with gene structural alterations and mutations resulting in the unregulated production of oncoproteins, matched by deranged biological fu...
