Study of gene regulation of nucleoside transporters in BeWo cell line
Strachoňová, Šárka ; Červený, Lukáš (advisor) ; Pávek, Petr (referee)
Charles University in Prague Faculty of Pharmacy in Hradec Králové Department of Pharmacology & Toxicology Student: Šárka Strachoňová Supervisor: PharmDr. Lukáš Červený, Ph.D. Title of diploma thesis: Studium of gene regulation of nucleoside transporters in BeWo cell line Nucleoside transporters (NTs) localized in syncytiotrophoblast control placental uptake of nucleosides. Dysregulation of NTs can disrupt nucleoside homeostasis with a negative consequences on placental and fetal development and can lead to a change in placental pharmacokinetics of nucleoside-derived drugs. Therefore, understanding the expression and function of NTs is necessary for effective and safe pharmacotherapy during pregnancy. The aim of this diploma thesis was to study the adenylate cyclase (AC) activated regulatory pathways of gene expression of concentrative nukleoside transporter 2 (CNT2). For this purpose, qRT-PCR and in vitro accumulation assays using the model substrate [3 H]-adenosine were employed. The human placental choriocarcinoma-derived BeWo cell line has been exposed to an AC activator, forskolin (50 µM), and/or inhibitors of AC/cAMP/PKA, AC/cAMP/MAPK (MEK1/2, p38 MAPK) signaling pathways, PKA inhibitor, KT 5720 (5 μM), an inhibitor of MEK1/2, U0126 (10 μM) and an inhibitor of p38 MAPK, SB202190 (10 μM).
