The adverse effects of maternal diabetes on embryo development and pregnancy outcomes have recently been shown to occur as early as the one-cell zygote stage. The hypothesis of this study was that maternally inherited mitochondria in oocytes from diabetic mice are abnormal and thus responsible in part for this latency of developmental compromise. In(More)
We previously identified a coregulator, repressor of estrogen receptor activity (REA), that directly interacts with estrogen receptor (ER) and represses ER transcriptional activity. Decreasing the intracellular level of REA by using small interfering RNA knockdown or antisense RNA approaches in cells in culture resulted in a significant increase in the(More)
Embryo implantation is a highly synchronized event between an activated blastocyst and a receptive endometrium. The success of this process relies on the dynamic interplay of estrogen (E(2)) and progesterone (P(4)), however, the details of this interaction are not entirely clear. Recent data implicate E(2) and P(4) in the regulation of glucose utilization(More)
Impaired oocyte quality has been demonstrated in diabetic mice; however, the potential pathways by which maternal diabetes exerts its effects on the oocyte are poorly understood. Cumulus cells are in direct contact with the oocyte via gap junctions and provide essential nutrients to support oocyte development. In this study, we investigated the effects of(More)
Recurrent miscarriages affect about 1-2% of couples trying to conceive; however, mechanisms leading to this complication are largely unknown. Most studies focus on the early embryo, but proper development and implantation of the blastocyst are also dependent on optimal endometrial progression into a receptive state. One of the key steps in the uterine(More)
OBJECTIVE This study compares surgical and survival outcomes of women with stage IV uterine serous carcinoma (USC) treated with neoadjuvant chemotherapy (NAC) and interval cytoreduction to women treated with primary cytoreductive surgery (PCS) followed by adjuvant chemotherapy. METHODS This retrospective dual cohort study included women diagnosed with(More)
Free fatty acids (FFAs) are energy substrates for many cell types, but in excess, some FFAs can accumulate in nonadipose cells, inducing apoptosis. Also known as lipotoxicity, this phenomenon may play a role in the development of obesity-related disease. Obesity is common among reproductive age women and is associated with adverse pregnancy and fetal(More)
Estrogens regulate multiple activities in breast cancer cells, including proliferation. Whereas these hormones are most commonly known to regulate gene transcription through direct interaction with estrogen receptors (ERs) and with specific DNA sequences of target genes, recent studies show that ER also activates a number of rapid signaling events that are(More)
The mechanism responsible for poor reproductive outcomes in type 1 diabetic males is not well understood. In light of new evidence that the Sertoli cells of the testis secrete insulin, it is currently unclear whether diabetic subfertility is the result of deficiency of pancreatic insulin, testicular insulin, or both. In this study, the Akita mouse diabetic(More)
Endometrial stromal cells (ESC) must undergo a hormone-driven differentiation to form decidual cells as a requirement of proper embryo implantation. Recent studies from our laboratory have demonstrated that decidualizing cells require glucose transporter 1 expression and an increase in glucose use to complete this step. The present study focuses on the(More)
