BACKGROUND AND OBJECTIVES: Experimental protocols for remote ischemic
conditioning (RIC) utilize models in which a tourniquet is placed around the
hindlimb or effluent is collected from an isolated heart. In analyzing the
humoral factors that act as signal transducers in these models, sampled blood can
be influenced by systemic responses, while the effluent from an isolated heart
might differ from that of the hindlimb. Thus, we designed a new isolated hindlimb
model for RIC and tested whether the effluent from this model could affect
ischemia/reperfusion (IR) injury and if the reperfusion injury salvage kinase
(RISK) and survivor activating factor enhancement (SAFE) pathways are involved in
RIC. MATERIALS AND METHODS: After positioning needles into the right iliac artery
and vein of rats, Krebs-Henseleit buffer was perfused using a Langendorff
apparatus, and effluent was collected. The RIC protocol consisted of 3 cycles of
IR for 5 minutes. In the RIC effluent group, collected effluent was perfused in
an isolated heart for 10 minutes before initiating IR injury. RESULTS: Compared
with the control group, the infarct area in the RIC effluent group was
significantly smaller (31.2%±3.8% vs. 20.6%±1.8%, p<0.050), while phosphorylation
of signal transducer and activation of transcription-3 (STAT-3) was significantly
increased. However, there was a trend of increased phosphorylation of
extracellular signal-regulated kinase (ERK) 1/2 in this group. CONCLUSION: This
is the first study to investigate the effect of effluent from a new isolated
hindlimb model after RIC on IR injury in an isolated heart model. The RIC
effluent was effective in reducing the IR injury, and the cardioprotective effect
was associated with activation of the SAFE pathway.
