The aim of the present study was to investigate the electrophysiological
properties of transient receptor potential melastatin 7 (TRPM7) channels in the
cell membranes of cardiac fibroblasts (CFs). CFs obtained from Sprague-Dawley
rats were treated with six different concentrations of angiotensin (Ang) II for
12 h. The optimum concentration of Ang II for inducing fibrosis was selected by
measuring collagen protein expression levels at each concentration. The optimum
concentration of Ang II was then used to treat the CFs at five different
time-points, and the TRPM7 current across the CF membranes was recorded along
with the collagen protein levels in each group. The optimum Ang II concentration
for inducing fibrosis was found to be 1 nmol/l; when it was administered to CFs
at 0, 6, 12, 24 and 48 h, the protein expression levels of TRPM7 and collagen III
initially increased, reaching maximum levels at 12 h, and then decreased. This
result positively correlated with the TRPM7 current levels on either side of the
CF membranes: The TRPM7 current under the effect of the optimal Ang II
concentration for inducing fibrosis was initially increased and then later
decreased. This is one of the key mechanisms by which Ang II mediates the
proliferation and apoptosis of CFs. This knowledge may be used to identify
treatments for the prevention of cardiac fibrosis.
