  • Title: [The temperature dependence of the respiration and phospholipid content of the mitochondria in the organs of heat-adapted rats].
    Author: Seferova RI, Manenkova ID, Sergienko EV, Babaeva AKh.
    Journal: Fiziol Zh SSSR Im I M Sechenova; 1990 Feb; 76(2):247-52. PubMed ID: 2163919.
    Abstract:
    A shift of breaking point to higher temperatures was illustrated on Arrhenius plots in kidney, liver and heart mitochondria of heat-adapted rats on 4.1, 2.7, 2.4 degrees C respectively. Q10 mitochondrion respiration fall in adapted animals in a range of 26-36 degrees C was indicative of temperature compensation. It was shown the elevation of phospholipid plasmalogen form content in heart and kidney mitochondria; as well as saturated fatty acids content in liver mitochondria. Structure and function changes were suggested to be the basic point of elevation of mitochondrion functional ability at high ambient temperature.
