Rapid simultaneous measurement of rat alpha- and thyrotropin (TSH) beta-subunit messenger ribonucleic acids (mRNAs) by solution hybridization: regulation of TSH subunit mRNAs by thyroid hormones.

abstract：:Hypothyroid patients and mice have been shown to have circulating TSH that is more highly sialylated than their euthyroid counterparts. To learn about the underlying cellular mechanisms responsible for this increased sialylation of TSH, we used in situ hybridization to examine the beta-galactoside alpha-2,6-sialyltran...
