Expression of Transcription Factor PRH/Hhex in Adrenal Chromaffin Cells in the Postnatal Development and Its Role in the Regulation of Proliferative Processes

Transcription factor PRH/Hhex suppresses cell proliferation and contributes to regulation of prenatal and postnatal ontogeny. Neurons of the peripheral nervous system and chromaffin cells were previously considered as non-expressing PRH/Hhex in postnatal development. In our study, the expression of PRH/Hhex in chromaffin cells of rat adrenal glands and association between the decrease of proliferation and activation of PRH/Hhex expression were demonstrated.
