..., Python regius , the tegu lizard, Tupinanvis merianae , and the varanid lizard, Varanus exanthematicus . Force-frequency trials and imposed pauses were performed on ventricular and atrial tissue from each species with and without the SR inhibitor ryanodine, and in the absence and presence of adrenaline...

... ) receptor (IP 3 R) and subsequent release of Ca 2+ from the sarcoplasmic reticulum (SR). IP 3 R-mediated release of SR Ca 2+ causes calcium-induced calcium release (CICR) via the ryanodine receptor (RyR), which can be sensitized by cyclic adeninediphosphate ribose (cADPR). cADPR is synthesized from NAD...

..., increased [Ca 2+ ] i . To assess the participation of inositol triphosphate (IP 3 ) generation, sarcoplasmic/endoplasmic reticulum (SR/ER) Ca 2+ depletion, and activation of store-operated Ca 2+ entry, we utilized thapsigargin and ryanodine to deplete Ca 2+ SR/ER stores and the inhibitory reagents TMB-8...

...H. A. Shiels; E. V. Freund; A. P. Farrell; B. A. Block ABSTRACT We used an isometric muscle preparation to test the hypothesis that yellowfin tuna Thunnus albacares utilize the intracellular Ca 2+ storage sites of the sarcoplasmic reticulum (SR) during routine contractions. Ryanodine (a blocker...

... requires Ca 2+ release from the sarcoplasmic reticulum. Contraction elicited by brief extracellular electrical stimulation was reduced by the removal of Ca 2+ or by the addition of 25 μ mol l −1 nicardipine in crayfish Ringer’s solution. Addition of 30 μ mol l −1 ryanodine with 1mmol l −1 caffeine induced...

... on either component. A single-channel recording suggested that the transient component was carried by a low-conductance channel. Certain compounds with insecticidal action (ryanodine, S-bioallethrin, deltamethrin and avermectin) did not affect calcium channel currents in these cells. These data suggest...

... were also treated with ryanodine to assess the importance of calcium release from the sarcoplasmic reticulum. Ventricle strips from skate and black dogfish showed a five-fold increase in force development when external calcium was raised from a physiological to a saturating level. Force development...
