Original Description (Extracted from the article) ... We observed significant 24%, 30% and 30% decreases in fibrinogen production when HuH7 cells were transfected with 30 nM of hsa-miR-29c, hsa-miR-29a and hsa-miR- 29b respectively, compared to cells transfected with a negative control precursor molecule (Figure 2A). A similar effect was also observed at lower concentrations (3.3 nM and 10 nM). These results confirm that transfection of hsa-miR-29 family members can reduce fibrinogen production.//Compared to the control condition transfected with hsa-miR-144, a decrease of all five fibrinogen transcripts was observed when HuH7 cells were transfected with hsa-miR-29a, hsa-miR-29b or hsa-miR-29c (Figure 2B). The FGB mRNA level is on average reduced by 56% compared to the non-transfected control, while FGA and FGG transcript levels show reductions of 51% and 42% respectively. ...

Elevated levels of fibrinogen are associated with increased risk of cardiovascular disease, whereas low fibrinogen can lead to a bleeding disorder. We investigated whether microRNAs (miRNAs), known to act as post-transcriptional regulators of gene expression, regulate fibrinogen production. Using transfection of a library of 470 annotated human miRNA precursor molecules in HuH7 hepatoma cells, and quantitative measurements of fibrinogen production, we identified 23 miRNAs with down-regulating (up to 64% decrease) and 4 with up-regulating effects (up to 129% increase) on fibrinogen production. Among the downregulating miRNAs, we investigated the mechanism of action of three hsa-miR-29 family members and hsa-miR-409-3p. Overexpression of hsa-miR-29 members lead to decreased steady-state levels of all fibrinogen gene (FGA, FGB, FGG) transcripts in HuH7 cells. Luciferase reporter gene assays demonstrated that this was independent of miRNA-fibrinogen 3'UTR interactions. In contrast, overexpression of hsa-miR-409-3p specifically lowered fibrinogen Bbeta (FGB) mRNA levels and this effect was dependent on a target site in the FGB mRNA 3'UTR. This study adds to the known mechanisms that control fibrinogen production, points towards a potential cause of variable circulating fibrinogen levels, and demonstrates that a screening approach can identify miRNAs that regulate clinically important proteins.
