摘要: The mineralocorticoid receptor (MR) cDNA we previously isolated from the rat hippocampus differs clone kidney at 5'-untranslated (5'UT) region. (alpha MR mRNA) and hippocampal (beta possess unique 5'UT sequences of 220 300 nucleotides, respectively, but share an invariant peptide-coding domain appear to encode identical protein. two mRNA variants may represent tissue-specific forms or be coexpressed in along with other variants. Here, report that three subtypes were found hippocampus; their relative abundance was as follows: alpha = beta >> gamma. differentially distributed within subfields, form being highly enriched CA2, dentate, fasciculum cinereum, indusium griseum, whereas gamma evenly through CA1-4. Adrenalectomy selectively increased content, ...
