Adaptive structural and functional evolution of the placenta protects fetal growth in high elevation deer mice

Abstract: Hypoxia at high elevations challenges gestational physiology in placental mammals, increasing rates of gestational complications. Adaptation to high elevation has limited many of these effects in humans and other mammals, offering potential insight into the developmental processes that lead to and protect against hypoxia-related gestational complications. However, our understanding of these adaptations has been limited by a lack of experimental work linking the functional, regulatory, and genetic underpinnings… Show more

“…Furthermore, despite the diversity of placental functions and cell types (Pavličev et al 2017), it remains unclear if and how tissue specialization in the mammalian placenta influences the evolution of genomic imprinting. Specialized placental layers evolve under distinct evolutionary pressures (e.g., (Sandovici et al 2022;Suhail et al 2022;Wilsterman et al 2023) and show differences in the extent of inter-specific epigenetic divergence (Decato et al 2017). Thus, specialization of placental tissues may influence regulatory divergence and select for different patterns of genomic imprinting across functional layers.…”
