Neonatal estrogen exposure disrupts uterine development in the postnatal sheep.

abstract：:Recent data suggest that proinflammatory cytokines secreted from adipose tissue contribute to the morbidity associated with obesity. However, characterization of the cell types involved in inflammation and how these cells promote insulin resistance in human adipocytes are unclear. We simulated acute inflammation using...

abstract：:Hypophyseotropic dopamine exerts a tonic inhibitory tone on pituitary lactotrophs by the activation of dopamine D2 receptors (D2R). Ablation of D2R through gene knock-out approaches results in hyperprolactinemia and prolactinomas. This phenotype is more severe and develops more rapidly in female mice. We tested whethe...
