  1. Proteomic Profile of Mabuya sp. (Squamata: Scincidae) Ovary and Placenta During Gestation

    Proteins expressed during gestation were identified in ovarian and placental tissues in the viviparous placentotrophic lizard Mabuya sp. Most of the proteins expressed are highly conserved and might play a similar role to those proteins regulating gestation and growing in amniote embryos.

    Our findings indicate that embryo exposure to sex determining temperatures induces differential expression of several genes that are involved not only in gonad differentiation, but also in neural differentiation, synaptic plasticity, and metabolic pathways.

    A dimorphic neural network seems to differentiate during the TSP. This is likely necessary for adult animals to show sex-specific behaviors that are required for copulation and reproduction. Our preliminary findings thus suggest that the brains of SDT reptiles might be dimorphic at birth (Pritz, 2015). Therefore, behavioral experiences in postnatal development, which have been demonstrated to contribute to the brain's SD in later life (Coomber et al., 1997), would act on a structure already committed to male or female.

  4. The Regulation of Uterine Proinflammatory Gene Expression during Pregnancy in the Live-Bearing Lizard, Pseudemoia entrecasteauxii

    During pregnancy, uterine proinflammatory gene expression is regulated transcriptionally (TNF) and posttranslationally (IL1B) in a live-bearing lizard, suggesting the presence of maternal immune regulation in reptilian viviparity.
