The Potential Roles of the Apoptosis-Related Protein PDRG1 in Diapause Embryo Restarting of Artemia sinica
High salinity and low temperatures can induce Artemia sinica to enter the diapause stage during embryonic development. Diapause embryos stop at the gastrula stage, allowing them to resist apoptosis and regulate cell cycle activity to guarantee normal development after diapause termination. P53 and DNA damage-regulated gene 1 (pdrg1) is involved in cellular physiological activities, such as apop...
متن کاملEmbryo-endometrial interactions during early development after embryonic diapause in the marsupial tammar wallaby.
The marsupial tammar wallaby has the longest period of embryonic diapause of any mammal. Reproduction in the tammar is seasonal, regulated by photoperiod and also lactation. Reactivation is triggered by falling daylength after the austral summer solstice in December. Young are born late January and commence a 9-10-month lactation. Females mate immediately after birth. The resulting conceptus de...
متن کاملPermanent embryo arrest: molecular and cellular concepts
Developmental arrest is one of the mechanisms responsible for the elevated levels of embryo demise during the first week of in vitro development. Approximately 10-15% of IVF embryos permanently arrest in mitosis at the 2- to 4-cell cleavage stage showing no indication of apoptosis. Reactive oxygen species (ROS) are implicated in this process and must be controlled in order to optimize embryo pr...
متن کاملUterine signaling at the emergence of the embryo from obligate diapause.
Embryonic diapause is the reversible arrest of embryo development prior to implantation under a regime of uterine control that is not well understood. Our objective was to explore uterine modifications associated with the emergence of embryonic diapause in the mink, a species in which embryonic diapause characterizes every gestation. We investigated the uterine transcriptome at reactivation usi...
متن کاملThe Aassociation between Pre-Cardiac Arrest Comorbidity and Unsuccessful Cardiopulmonary Resuscitation in Patients with Cardiac Arrest
Background and Objective: Patients suffering from cardiac arrest (CA) have poor prognosis and survival. The association of pre-arrest comorbidity with unsuccessful resuscitation in patients with CA is far from clear. The aim of the present study was to investigate the association between pre-existing comorbidity and unsuccessful resuscitation following CA in Iranian patients. Materials and Met...
