Abstract

The development of cryopreservation methods for testicular spermatozoa makes it possible to safely and economically reproduce genetically diverse agricultural and numerous endangered animal species. The effect of the TSKY peptide (Thr–Ser–Lys–Tyr) isolated from the brains of winter-sleeping ground squirrels (Spermophillus undulatus) in a state of deep hibernation on the physiological activity of bovine sperm cells was studied. A decrease in the activity of bovine rapidly moving spermatozoa was shown when the TSKY peptide was added at the thawing stage after cryopreservation of reproductive cells in liquid nitrogen (–196°C).

TSKY肽对牛精子生理活性的影响

睾丸精子冷冻保存方法的发展使得安全、经济地繁殖具有遗传多样性的农业和许多濒危动物物种成为可能。本文研究了深冬眠地松鼠脑中TSKY肽（Thr-Ser-Lys-Tyr）对牛精子细胞生理活性的影响。生殖细胞在液氮（-196°C）中低温保存后，在解冻阶段加入TSKY肽可降低牛快速移动精子的活性。

期刊介绍： Biophysics is a multidisciplinary international peer reviewed journal that covers a wide scope of problems related to the main physical mechanisms of processes taking place at different organization levels in biosystems. It includes structure and dynamics of macromolecules, cells and tissues; the influence of environment; energy transformation and transfer; thermodynamics; biological motility; population dynamics and cell differentiation modeling; biomechanics and tissue rheology; nonlinear phenomena, mathematical and cybernetics modeling of complex systems; and computational biology. The journal publishes short communications devoted and review articles.
