Glucocorticoids modulate drug transporter function in human fetal brain endothelial cells

The Journal of Physiology, EarlyView.
Abstract figure legend P‐glycoprotein and breast cancer resistance protein are the most prominent drug transporters at the fetal blood–brain barrier. We isolated primary human fetal brain endothelial cells from early and mid‐gestation cerebral microvessels and exposed them to glucocorticoids cortisol and dexamethasone in vitro.

Physiological and anatomical determinants of placental drug transfer

The Journal of Physiology, EarlyView.
Abstract figure legend Fetal exposure to pharmaceuticals and their subsequent clearance back to the maternal circulation are governed by placental transfer. Passive diffusion down a maternal‐to‐fetal concentration gradient is the primary route of fetal drug exposure, with specific compounds undergoing transporter‐mediated transfer.

Expression and significance of CD133 and ABCG2 in endometriosis

Clinical and Experimental Obstetrics & Gynecology, 2015
Endometriosis is a common gynecological disease and exact pathogenesis is still unclear. Recently, an increasing interest has been given to the potential role of stem cells in the development of endometriosis. The aim of this study was to test the expression of sterness-related markers CD133 and ABCG2 in endometriosis.CD133 and ABCG2 protein expression

Chemotherapeutic Drug-Induced ABCG2 Promoter Demethylation as a Novel Mechanism of Acquired Multidrug Resistance

Neoplasia: An International Journal for Oncology Research, 2009
ABCG2 is an efflux transporter conferring multidrug resistance (MDR) on cancer cells. However, the initial molecular events leading to its up-regulation in MDR tumor cells are poorly understood.

A primary cell‐based fluidic co‐culture model to investigate drug transport across the human placenta

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic overview of a flow‐driven in vitro model of the human placental barrier designed to study transport processes during pregnancy. The model recreates key features of the maternal–fetal interface, enabling the investigation of how nutrients and therapeutic compounds cross the placental barrier under physiologically ...

A review of xenobiotic membrane transporter expression within the human placenta: Lessons gained from primary tissue and in vitro methodologies

The Journal of Physiology, EarlyView.
Abstract figure legend A summary of the current knowledge around membrane transporter expression in the most widely used in vitro models of human trophoblasts, including primary placental tissue, cancer cell lines and trophoblast stem cells, as well as the techniques to attempt to mimic the human placenta in vivo.

Maternal nutrition as a key determinant of placental and developing blood–brain barrier xenobiotic protective functions

The Journal of Physiology, EarlyView.
Abstract figure legend Suboptimal maternal nutrition alters placental and developing blood–brain barrier (BBB) protective function and is associated with increased fetal brain vulnerability. In the placenta, nutritional adversity may reduce the exchange surface area and promote meta‐inflammation, compromising barrier efficiency in a model‐ and context ...

Expression of Aldehyde Dehydrogenase (ALDH1) and ATP Binding Cassette Transporter G2 (ABCG2) in Iraqi Patients with Colon Cancer and the Relation with Clinicopathological Features [PDF]

International Journal of Molecular and Cellular Medicine, 2018
Tumor initiation cells or cancer stem cell markers ABCG2 and ALDH1 play pivotal roles in invasion, metastasis, and resistance to cytotoxic agents. In this study, we evaluated the expression levels of ALDH1 and ABCG2 in Iraqi patients with colon cancer ...

Sitravatinib, a Tyrosine Kinase Inhibitor, Inhibits the Transport Function of ABCG2 and Restores Sensitivity to Chemotherapy-Resistant Cancer Cells in vitro

Frontiers in Oncology, 2020
Sitravatinib, also called MGCD516 or MG-516, is a broad-spectrum tyrosine kinase inhibitor (TKI) under phase III clinical evaluation. Herein, we explored the activity of sitravatinib toward multidrug resistance (MDR) by emphasizing its inhibitory effect ...

microRNA‐145‐5p regulates P‐glycoprotein and breast cancer resistance protein in primary human fetal brain endothelial cells

The Journal of Physiology, EarlyView.
Abstract figure legend Drug transporters P‐glycoprotein (P‐gp) and breast cancer resistance protein (BCRP) at the blood–brain barrier (BBB) protect the rapidly developing fetal brain. We investigated the role of microRNA‐145‐5p (miR‐145‐5p) microRNA (miRNA) in regulating these key transporters in primary human fetal brain endothelial cells in vitro. We
