αB-crystallin expression in rat hearts heat-treated <i>in vivo</i>.

<p>αB-crystallin expression in rat heart tissue decreased (<i>P</i><0.01) at 20 min of heat stress compared to the control and then significantly increased (<i>P</i><0.01) at 40 min of heat stress. After 60 min of heat stress, αB-crystallin expression levels decreased again (<i>P</i><0.01) and remained at lower levels until 100 min of heat stress. However, the level of αB-crystallin in dead rats was much higher than those of the control and all other heat-stressed groups. ** <i>P</i><0.01; *<i>P</i><0.05.</p>
