Abstract
Background: In response to the high-glucose environment in patients with gestational diabetes mellitus (GDM), trophoblast cells undergo a series of pathological changes. Gamma-aminobutyric acid type A receptor subunit pi (GABRP) is involved in the development of pregnancy-related diseases and regulation of blood glucose.
Objectives: To explore the relationship between GABRP and hyperglycemia stimulation in GDM patients, and to provide preliminary experimental evidence for whether GABRP has the potential as a molecular target for the treatment of GDM.
Material and methods: Within 30 min after birth, placental samples were taken from 20 GDM patients and 20 pregnant women without GDM. Human chorionic trophoblast HTR-8/SVneo cells were utilized for in vitro experimental investigation. We explored changes in GABRP expression in placental samples and HTR-8/Svneo cells using western blot and quantitative reverse transcription polymerase chain reaction (RT-qPCR). Cells in the high-glucose treatment group were exposed to medium containing 25 mM glucose. To explore the relationship between GABRP and high-glucose stimulation, GABRP was overexpressed in HTR-8/SVneo cells. We monitored the cell viability, invasion and migration abilities using Cell Counting Kit-8 (CCK-8), transwell and scratch assays, respectively.
Results: We found that GABRP expression was significantly reduced in placental samples from GDM patients. Furthermore, high-glucose treatment decreased the expression level of GABRP in HTR-8/SVneo cells. High-glucose stimulation reduced the cell viability, invasion and migration abilities. GABRP overexpression reversed the biological dysfunction of the cells induced by high-glucose stimulation.
Conclusions: Hyperglycemia in GDM patients downregulates the expression of GABRP, and overexpression of GABRP promotes the viability, migration and invasive ability of HTR8-/SVneo cells.
期刊介绍:
Advances in Clinical and Experimental Medicine has been published by the Wroclaw Medical University since 1992. Establishing the medical journal was the idea of Prof. Bogumił Halawa, Chair of the Department of Cardiology, and was fully supported by the Rector of Wroclaw Medical University, Prof. Zbigniew Knapik. Prof. Halawa was also the first editor-in-chief, between 1992-1997. The journal, then entitled "Postępy Medycyny Klinicznej i Doświadczalnej", appeared quarterly.
Prof. Leszek Paradowski was editor-in-chief from 1997-1999. In 1998 he initiated alterations in the profile and cover design of the journal which were accepted by the Editorial Board. The title was changed to Advances in Clinical and Experimental Medicine. Articles in English were welcomed. A number of outstanding representatives of medical science from Poland and abroad were invited to participate in the newly established International Editorial Staff.
Prof. Antonina Harłozińska-Szmyrka was editor-in-chief in years 2000-2005, in years 2006-2007 once again prof. Leszek Paradowski and prof. Maria Podolak-Dawidziak was editor-in-chief in years 2008-2016. Since 2017 the editor-in chief is prof. Maciej Bagłaj.
Since July 2005, original papers have been published only in English. Case reports are no longer accepted. The manuscripts are reviewed by two independent reviewers and a statistical reviewer, and English texts are proofread by a native speaker.
The journal has been indexed in several databases: Scopus, Ulrich’sTM International Periodicals Directory, Index Copernicus and since 2007 in Thomson Reuters databases: Science Citation Index Expanded i Journal Citation Reports/Science Edition.
In 2010 the journal obtained Impact Factor which is now 1.179 pts. Articles published in the journal are worth 15 points among Polish journals according to the Polish Committee for Scientific Research and 169.43 points according to the Index Copernicus.
Since November 7, 2012, Advances in Clinical and Experimental Medicine has been indexed and included in National Library of Medicine’s MEDLINE database. English abstracts printed in the journal are included and searchable using PubMed http://www.ncbi.nlm.nih.gov/pubmed.
