Abstract

The content of tyrosine varied at different phases of the oestrouscycle in the normal rat, i.e. being lowest in proestrus and highest in metestrus, while the progesterone receptor content in the same cytosol sample determined by radio-receptor technique showed an opposite relationship. Futhermore, administration of tyrosine to the uterine lumen decreased significantly the contents of progestrone receptor in proestrus, oestrus and diestrus, but not in metestrus. It is suggested that tyrosine might exert a certain regulatory influence on the progestrone receptor content.
