Immortality of cancers
Immortality is a common characteristic of cancers, but its origin and purpose are still unclear. Here we advance a karyotypic theory of immortality based on the theory that carcinogenesis is a form of speciation. Accordingly, cancers are generated from normal cells by random karyotypic rearrangements and selection for cancer-specific reproductive autonomy. Since such rearrangements unbalance lo...
متن کاملImmortality.
“Is death necessary?“, asked biologist G. R. Taylor and stated that in 1968 in the USA alone more than a thousand teams of scientists were working on the issue of growing old and the problem of death. Some people are frozen at their death. They want to be revived as soon as a cure for their disease or the aging process has been found. Most of humanity seems to have the desire to live forever. M...
متن کاملEnabling Replicative Immortality
Molecular aspects of cancer continue to be uncovered by researchers around the world. Theses aspects will need to be exploited in the next generation of cancer treatments. Specific tumor suppressor genes such as p53 can serve as novel therapeutic targets as well. Although the scientific understanding of the actual steps in tumorigenesis is rather muddled, the differences between cancer and norm...
متن کاملAging, fertility, and immortality.
Evolutionary theory suggests that fecundity rates will plateau late in life in the same fashion as mortality rates. We demonstrate that late-life plateaus arise for fecundity in Drosophila melanogaster. The result qualitatively fits the evolutionary theory of late life based on the force of natural selection. But there are a number of alternative interpretations. Fecundity plateaus could be sec...
متن کاملMortality and Immortality
Mortality and Immortality It has been known for centuries that the rich and famous have longer lives than the poor and ordinary. Causality, however, remains trenchantly debated. The ideal experiment would be one in which status and money could somehow be dropped upon a sub-sample of individuals while those in a control group received neither. This paper attempts to formulate a test in that spir...
