Biological immortality refers to stable or declining mortality rates based on chronological age-based cellular senescence. Biological immortality (sometimes called biological indeterminate mortality) is a state in which mortality due to aging stabilizes or declines, distinguishing it from chronological age. A biologically immortal creature can still die from causes other than aging, such as injury or disease.
Immortality does not mean that the organism cannot die, but that it can no longer die as it ages. Biological immortality means that if no external force causes damage to some cells and organisms, they can continue to exist, because there are no internal forces that bring them to an end. Death occurs due to external factors, but biologically immortal organisms are not subject to the same internal mechanisms that cause aging in biologically dead cells. A cell or organism that does not experience aging or will stop aging in the future is biologically immortal.
Slight aging is used to describe life that appears to have no biological aging. In many organisms, stem cells lose their ability to replace dysfunctional cells with age. Over time, senescent cells lose control of transposon inhibition. It has been suggested that the expression of transposons plays a role in aging, but why cells in the human body eventually lose control of this pathway remains a mystery.
Humans have stem cells that can repair and even regenerate body parts such as the liver, but the human body is not composed almost entirely of these cells like the animal group. Humans can’t just get rid of their old cells like the hydra does, because we need them. Preventing the aging of the human body is not enough to achieve immortality.
To go beyond this limit, humans must stop cellular aging and prevent disease. To achieve the more limited goal of stopping mortality from increasing with age, a solution must be found where any intervention that removes senescent cells increases cell-to-cell competition, thereby increasing cancer-related mortality. From the perspective of multicellular organisms, immortality can be an undesirable condition because the main control of cancer is the apoptotic mechanism.
Among the most commonly used cell lines are HeLa and Jurkat, both of which are immortalized cancer cells. The two most commonly used immortalized cancer cell lines are used in cancer research and various other types of research. Immortal tumor cell lines can be created by the induction of oncogenes or the loss of tumor suppressor genes.
Ironically, while all normal human cells have a Hayflick limit, the cells that were first identified as “immortal” were cancer cells. Biologists have chosen the word “immortal” to refer to cells not subject to the Hayflick limit, the point at which cells can no longer divide due to DNA damage or telomere shortening. Scientists attribute “biological immortality” to cells that are not subject to the Hayflick constraint and can reproduce an unlimited number of times.
The term “immortality” was first applied to cancer cells that expressed telomerase, an enzyme that lengthens telomeres, and thus avoided apoptosis, meaning the cnidarians present us with another form of “immortality” by asking if there is a genetic copy that continues to live. can be considered the same organism or not. Becoming is not the same as literal immortality, since people can always die or die in an accident. The answer depends on what you think it means to be an immortal person.
Evolutionary biologist Michael Ross has discovered a natural way to achieve “biological immortality” without the use of anti-aging drugs and stem cell therapy, says evolutionary biologist Michael Ross, a professor at the University of California, Irvine.
“The fact that such a variety of eukaryotes [all life forms except bacteria] can have infinite lifespans suggests that there is simply nothing in eukaryotic cells or molecular biology that requires an aging process,” he said. `Aristotle’s point of view is that aging is an inevitability, mainly caused by the accumulation of molecular damage and the decline of bodily functions. Furthermore, evolutionary biologist Michael Ross explained that the aging phase eventually passes, and survival reaches a plateau when the immortal phase begins. Evolutionary biologist Michael Ross believes that if humans live long enough, they too will go through a stage of biological immortality. The authors argue that humans will eventually reach this ageless period, as will many other multicellular life forms, such as creosote bushes that grow in the Mojave Desert, which live for more than 10,000 years, and other long-lived creatures, including some animals .
Some species suspected of biological immortality age too slowly for modern science to accurately observe how they lose steam. Turtles and tortoises have long been considered biologically immortal due to their long life and reproductive health in old age. Since then, turtles have become a gray area in the world of biological immortality, as some researchers suggest a possible, albeit slow, loss of fitness in old age.
Hydra Ageless, scientifically known as Ageless, is due to the seemingly endless regenerative capacity of stem cells. It appears that siphons can continue to reproduce and replace their units indefinitely, thus maintaining the “immortality” of genetic individuals. However, this does not make lobsters immortal in the traditional sense, as they are more likely to die during shedding of their shells as they get older. The problem they face on their journey to immortality (besides human culinary fantasies) is their protective exoskeleton.
