Key result

Atrial natriuretic peptide differentially modulates voltage-dependent calcium channels in bovine glomerulosa cells, stimulating L-current while inhibiting T-current.

Implication

May implicate T-type channel inhibition in ANP-mediated aldosterone suppression; leaves open human relevance.

Structured PICO

P
Population
Bovine glomerulosa cells
I
Intervention
Atrial natriuretic peptide (ANP)
O
Outcome
Modulation of T- and L-type calcium currents measured via patch-clamp techniquesurrogate

ANP-induced inhibition of aldosterone secretion may be partially mediated via a reduction of calcium current through T-type channels.

Cite This Study

McCarthy et al. (1990) studied this question. Atrial natriuretic peptide (ANP) was evaluated on Effect on T- and L-type calcium channels. Atrial natriuretic peptide differentially modulates voltage-dependent calcium channels in bovine glomerulosa cells, stimulating L-current while inhibiting T-current.
