Expression Of Nicotinic Acetylcholine Receptor Mrna As A Function Of Age In Whole Hippocampus Preparations From Wistar Rats, Kasey C. Welch
Expression Of Nicotinic Acetylcholine Receptor Mrna As A Function Of Age In Whole Hippocampus Preparations From Wistar Rats, Kasey C. Welch
Theses and Dissertations
Whole hippocampus preparations, isolated bilaterally, from untreated Wistar rats at various ages (10-90 days old) were analyzed for the mRNA expression of the alpha 2, alpha 3, alpha 4, alpha 5, alpha 7, beta 2, beta 3, and beta 4 neuronal nicotinic acetylcholine receptor subunits. To do so, RNA was isolated from acutely isolated hippocampal samples, converted to cDNA by means of a reverse transcription reaction, then analyzed with quantitative real-time PCR to determine the relative levels of the mRNAs the cells were expressing at the age when the samples were obtained. The relative expression of the levels of RNA …
Classification Of Neuronal Nicotinic Acetylcholine Receptors In Rat Ca1 Hippocampal Interneuron Subpopulations Defined By Calcium-Binding Protein Mrna Expression, Richard M. Burgon
Classification Of Neuronal Nicotinic Acetylcholine Receptors In Rat Ca1 Hippocampal Interneuron Subpopulations Defined By Calcium-Binding Protein Mrna Expression, Richard M. Burgon
Theses and Dissertations
In this study, the single-cell relative quantitative mRNA expression of three Calcium-binding proteins (CaBPs; calbindin, calretinin, parvalbumin) and eight nicotinic acetylcholine receptor (nAChR) subunits (alpha2-alpha5, alpha7, beta2-beta4) from interneurons from the stratum radiatum or stratum oriens within the CA1 region of rat hippocampi was analyzed using quantitative real time RT-PCR. Eighty-seven percent of the interneurons examined expressed CaBP mRNA. Parvalbumin mRNA was detected in 64%, while calbindin and calretinin expression was detected in 26% and 40% of interneurons, respectively. CaBP expression was not exclusive; the average number of CaBP mRNA detected per interneuron of the 47 interneurons examined for CaBP …
