2004 SEP 15 - (NewsRx.com & NewsRx.net) -- Thyroid status co-regulates genes of the hypothalamus.
According to recent research published in the journal FEBS Letters, "regulation of thyrotropin releasing hormone (TRH) transcription in the hypothalamus represents the central control point of thyroid function. To examine the expression of potential TRH regulatory components, we simultaneously amplified, by semi-quantitative multiplex polymerase chain reaction (PCR) system, nine key genes from less than or equal to100 ng total RNA from two brain areas (hypothalamus and ...
