To establish whether a direct functional relationship exists between FMR-1 expression and cyclic AMP production in neural cells.
Overexpressed human FMRP isoforms 1 and 7 in the HN2 neurotumor hybrid cell line.
Quantified FMR-1 mRNA and FMRP levels via Northern and Western blotting across clonal overexpressing and nonoverexpressing control cell lines.
Measured intracellular cAMP production across cell lines to evaluate the impact of FMRP abundance.
Cyclic AMP production in clonal HN2 cells overexpressing FMRP was significantly higher than in nonoverexpressing control lines.
Intracellular cAMP synthesis increased in direct proportion to rising levels of total FMR-1 mRNA and FMRP protein.
