If there really is such an incredible drug as APTX——4869, just putting forward the basic theory is enough to win the Nobel Prize.
According to the story of Detective Conan, APTX——4869 will cause death after taking it, and the toxin will disappear within a few minutes after death, even if the forensic autopsy can't find out the cause of death. However, this drug has not been successfully developed, and it will have side effects under accidental action, which can make biological cells degenerate sharply to early childhood.
from this point of view, APTX——4869 is a drug that can make cells die explosively, and it forcibly changes the genes in biological cells by unnatural means to make them mutate.
anyone who has studied biology knows that biological cells are controlled by genes, and genes are the main genetic material. There is a program in genes called "apoptosis". Apoptosis is a normal physiological phenomenon of orderly self-death controlled by biological genes. Through apoptosis, aging, mutation and useless cells die on their own, so as to maintain the normal operation of biological functions.
However, APTX——4869 is a drug that violates the laws of nature. It interferes with this process, causing the cells in the organism to die in large quantities without control, and eventually leading to the death of the organism itself.
With the level of modern science and technology, the technology to mutate cells has been available, but it is not mature. And this incredible phenomenon that makes people shrink like APTX——4869 can't be done yet.
