Darwin's Pangenesis as a molecular theory of inherited diseases

摘要

Darwin spent much time and effort on the study of inherited diseases and the role of environment in disease development. To explain inherited diseases and a considerable variety of other hereditary phenomena, he formulated a Pangenesis hypothesis, assuming that cells could shed many kinds of molecules capable of diffusion from cell to cell, circulation throughout the body, incorporation into recipient cells, and transmission from parents to offspring. His Pangenesis is now supported by the discovery of circulating DNA, mobile RNAs and prions, and might provide an alternative molecular mechanism underlying the inherited diseases.
