Key result
Aldosterone activates the MAPK cascade in renal epithelial cells through a genomic mechanism involving induction of Ki-ras transcription, resulting in delayed but prolonged signaling.
Why the study?
Does aldosterone activate the MAPK cascade via induction of Ki-ras in renal A6 epithelial cells?
Does aldosterone activate the MAPK cascade via induction of Ki-ras in renal A6 epithelial cells?
Aldosterone activates the MAPK cascade through a delayed, prolonged genomic mechanism involving the induction of Ki-ras transcription, distinct from traditional mitogens.

Hypothesis-generating for genomic aldosterone signaling in renal cells; leaves open relevance to clinical mineralocorticoid effects.
Hendron et al. (2002) studied In vitro (Renal A6 epithelial cells). Aldosterone vs. Vehicle was evaluated on MAPK activity and Ki-RasA levels. Aldosterone activates the MAPK cascade in renal epithelial cells through a genomic mechanism involving induction of Ki-ras transcription, resulting in delayed but prolonged signaling.
