title: Physiology and Endocrinology Symposium: heat shock proteins: potentially powerful markers for preimplantation embryonic development and fertility in livestock species.
abstract: For the mammalian embryo to successfully complete development, it must not only incur proper timing of internal machinery, but also protect itself from potentially harmful external stimuli. These stimuli, ranging from chemical to temperature flux, can result in defects in processes regulating gamete production and quality, as well as early embryonic development. To counterbalance these potential detriments, the mammalian cell has complex machinery consisting of heat shock factors and proteins that prevent protein misfolding and malfunction. Heat shock protein (HSP) genes have become a growing topic to understand the mechanisms of successful gamete formation and embryonic development, critical factors for livestock fertility. In addition, HSP have become a focus in understanding how external stimuli during the in vitro embryo production process may have a developmental impact. To further elucidate these mechanisms, it has become a necessity for more in-depth functional studies on HSP using technologies such as RNA interference and antibody use during embryo culture. Through these studies we can gain a more comprehensive perspective of HSP function and importance during early development. In addition, information from these studies may provide critical markers for improved fertility and development.
