Regulation of overgrowth and expression of prostatic binding protein in rat chimeric prostate gland.

abstract：:Previously, three receptors, xTRHR1, xTRHR2, and xTRHR3, were cloned from brain tissue of Xenopus laevis with primers designed using sequences from the mammalian TRH receptor (TRHR) subtype 1. We expressed the Xenopus receptors in HEK 293EM cells and studied their binding and signaling properties using a series of TRH...
