I was searching for Hypothalamic-pituitary-adrenal axis gene expression and found this article:
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC16901/
Gene expression profiling in the human hypothalamus-pituitary-adrenal axis and full-length cDNA cloning
I'm just ChEfag so I get lost in the jargon. Maybe some Biofag can translate for us.
About cDNA, tho
https://en.wikipedia.org/wiki/Complementary_DNA
cDNA = Complementary DNA = DNA synthesized from single stranded RNA (such as mRNA)
And we all know what mRNA is now, don't we boys.
