Hormonal imprinting
Encyclopedia
Hormonal imprinting is a phenomenon which takes place at the first encounter between a hormone
and its developing receptor
in the critical periods of life (in unicellulars during the whole life) and determines the later signal transduction
capacity of the cell. The most important period in mammals is the perinatal one, however this system can be imprinted at weaning
, at puberty
and in case of continuously dividing cells during the whole life. Faulty imprinting is caused by drugs
, environmental pollutants and other hormone-like molecules present in excess at the critical periods with life-long receptorial, morphological, biochemical and behavioral consequences. HI is transmitted to the hundreds of progeny generations in unicellulars and (as proved) to a few generations also in mammals.
Hormone
A hormone is a chemical released by a cell or a gland in one part of the body that sends out messages that affect cells in other parts of the organism. Only a small amount of hormone is required to alter cell metabolism. In essence, it is a chemical messenger that transports a signal from one...

Hormone receptor
A hormone receptor is a receptor protein on the surface of a cell or in its interior that binds to a specific hormone. The hormone causes many changes to take place in the cell....

Signal transduction
Signal transduction occurs when an extracellular signaling molecule activates a cell surface receptor. In turn, this receptor alters intracellular molecules creating a response...

Weaning
Weaning is the process of gradually introducing a mammal infant, either human or animal, to what will be its adult diet and withdrawing the supply of its mother's milk.The process takes place only in mammals, as only mammals produce milk...

Puberty is the process of physical changes by which a child's body matures into an adult body capable of reproduction, as initiated by hormonal signals from the brain to the gonads; the ovaries in a girl, the testes in a boy...
