Discovery of putative aldosterone-regulating microRNAs by analysis of in vitro and in vivo microRNA profiles

Approximately 10% of essential hypertension cases is attributed to primary aldosteronism (PA), where inappropriately high levels of aldosterone are secreted. Almost half of these PA cases result from aldosterone-producing adenoma. microRNAs are single-stranded, short non-coding RNAs that negatively regulate gene expression post-transcriptionally. In a previous study, we showed that microRNAs directly modulate CYP11B2 (aldosterone synthase) gene expression and aldoster...

Bioinformatic analysis of microRNAs associated with aldosterone secretion

Ab Razak Nur Izah , MacKenzie Scott M , Diver Louise A , McBride Martin M , Davies Eleanor

Many cases of hypertension are associated with inappropriately high levels of aldosterone secretion and it has been proposed that microRNAs play a role in this dysregulation. Previously, we showed that microRNAs expressed within the adrenal cortex significantly repress aldosterone production. Furthermore, stimulation of aldosterone secretion by three different means in the H295R cell line – the most commonly-used in vitro model of the human adrenal cortex – ...
