Resting membrane potential (RMP) is depolarized and store-operated Ca2+ entry (SOCE) is diminished in ρ0 myoblasts.
(A) Comparison of RMP between control (n=8) and ρ0 myoblasts (n=12). (B) Average [Ca2+]i between control (n=13) and ρ0 myoblasts (n=6) in the resting state. (C) Average trace recordings of [Ca2+]i, which increased following thapsigargin (2 µM) treatment of control (black) and ρ0 (gray) myoblasts. Data are means±standard error of the mean (n=3). **p<0.01.
