Perturbation of placental endocrine function by endoplasmic reticulum stress leads to maladaptation of maternal hepatic glucose metabolism

To investigate whether ER stress underpins the secretion of mis-glycosylated glycoproteins by trophoblast, we treated trophoblast-like BeWo cells with the ER stress inducer thapsigargin (Tg), an inhibitor specific for sarco/endoplasmic reticulum Ca2+-ATPase.
