| contents | (Uploaded by Plazi for the Bat Literature Project) Hibernation is an adaptive strategy used by some animals to cope with cold and food shortage. The heart rate, overall energy need, body temperature, and many other physiological functions are greatly reduced during torpor but promptly return to normal levels upon arousal. The heartbeat of torpid bats can be hundreds fold lower than that of active bats, indicating that hibernating bats have a remarkable ability to control excitationcontraction coupling in cardiac muscle. FKBP1B (calstabin 2), a peptidyl-prolyl cis-trans isomerase, is critical for the regulation of excitation-contraction coupling. Whether FKBP1B is adapted to hibernation in bats is not known. Evolutionary analyses showed that the ω values of the Fkbp1b genes of 25 mammalian species are all less than 1, and amino acid sequence alignments revealed that FKBP1B proteins are highly conserved in mammals. The expression of the Fkbp1b gene was found to be elevated at both mRNA and protein levels in two distantly related bats (Rhinolophus ferrumequinum in Yinpterochiroptera and Myotis ricketti in Yangochiroptera) during torpor. Transcription factors such as YY1 and SPs were bioinformatically determined to have a higher binding affinity to the potential regulatory regions of Fkbp1b genes in hibernating than in non-hibernating mammals. This study provides new insights into the molecular evolution of Fkbp1b in adaptation to bat hibernation. |
