Calcium dependence of prolactin mRNA accumulation in GH3 rat pituitary tumour cells.


Stimulation of prolactin secretion by TRH probably involves mobilization of intracellular calcium to a greater extent than calcium influx, but less is known about the possible calcium-dependent mechanisms which may control prolactin gene transcription. We have studied this question in the rat pituitary tumour GH3 cell line by measuring prolactin mRNA… (More)
