Purpose: To investigate F2 and miR-451a levels in gestational diabetes mellitus (GDM) patients, evaluate the potential role of miR-451a in GDM, and to explore its possible downstream targets. Methods: Thromboelastography (TEG) analysis was conducted to analyze coagulation differences between the GDM and control groups. Quantitative polymerase chain reaction (qPCR) and immunoblot were performed to analyze miR-451a and F2 levels after exposure to high glucose and miR-451a mimics or an miR-451a inhibitor. Luciferase assay was used to explore the potential regulatory mechanism. Results: Enhancement of the patients' blood coagulation ability and down-regulated miR-451a expression levels occurred in the plasma of GDM patients. The data further show that hepatocytes exposed to high glucose reduced miR-451a levels and enhanced F2 expression. The  overexpression of miR-451a inhibited the expression of F2. Conclusion: MiR-451a may serve as a promising marker for hypercoagulable state GDM patients Keywords: Gestational diabetes mellitus (GDM), MiR-451a, F2, Hypercoagulable state, Prothrombin, Thromboelastography (TEG)

AbstractThe incidence of gestational diabetes mellitus (GDM) has increased dramatically amongst multiethnic population. However, how gestational diabetes mellitus damages the developing embryo is still unknown. In this study, we used yolk sac membrane (YSM) model to investigate angiogenesis in the developing chick embryo. We determined that in the presence of high glucose, it retarded the growth and extension of the embryonic vascular plexus and it also reduced the density of the vasculature in yolk sac membrane model. Using the same strategy, we used the chorioallantoic membrane (CAM) as a model to investigate the influence of high glucose on the vasculature. We established that high glucose inhibited development of the blood vessel plexus and the blood vessels formed had a narrower diameter than control vessels. Concurrent with the abnormal angiogenesis, we also examined how it impacted cardiogenesis. We determined the myocardium in the right ventricle and left atrium were significantly thicker than the control and also there was a reduction in glycogen content in cardiomyocytes. The high glucose also induced excess reactive oxygen species (ROS) production in the cardiomyocytes. We postulated that it was the excess reactive oxygen species that damaged the cardiomyocytes resulting in cardiac hyperplasia.

Abstract Background: Gestational diabetes mellitus (GDM) is a disease condition present during pregnancy and if not properly managed would have severe effect on the maternal and neonatal health. This research determined the effect of diabetes education program (DEP) on gestational diabetes mellitus knowledge (GDMK) among diabetic pregnant women (DPW) and significant differences within groups.Methods: This study was based on a pretest – posttest measures of experimental research design involving experimental (n=110) and control (n=110) groups. A total of 220 DPW were purposively recruited from public hospitals in Nigeria between October and December 2019. The DEP was delivered to DPW in experimental group. The Gestational Diabetes Mellitus Knowledge Questionnaire (GDMKQ) of 0.774 was used for data collection. The statistical analysis was completed using IBM SPSS version 22. Results: The results revealed that no statistically significant difference existed on GDM history (P=0.801>0.05), smoking habit (P=0.0615>0.05), parity status (P=0.503>0.05), and level of education (P=0.720>0.05), while difference was observed on alcohol status (P=0.011<0.05), and age by birth (P=0.009<0.05). Also, while no significant difference existed between the DPW in the treatment and control groups on GDMK pretest measures (P=0.901>0.05), difference existed between the DPW in the intervention and control groups on GDMK posttest scores (P=0.026<0.05). Also, the higher percentage score (78%) of DPW in the experimental group in the posttest GDMK measures which is higher than the score in the pretest measures (55%) of the same group were indications that DEP has significant effect on GDMK among DPW.Conclusion: This demonstrates that reliable interventions are effective in combating pregnancy-related complications. This requires collaborative efforts by concerned bodies to combat notable complications during pregnancy using reliable intervention.Trial Registration: In retrospect, the Pan African Clinical Trial Registry documented the study with registration trial code (Trial No.: PACTR201903003187005)

Omental Adipose Tissue

Omental adipose tissue plays a central role in insulin resistance in gestational diabetes mellitus (GDM), and the molecular mechanisms leading to GDM remains vague. Evidence demonstrates that maternal hormones, such as estradiol, contribute to insulin resistance in GDM. In this study we determined the differential expression patterns of microRNAs (miRNAs) in omental adipose tissues from GDM patients and pregnant women with normal glucose tolerance using AFFX miRNA expression chips. MiR-222, 1 of 17 identified differentially expressed miRNAs, was found to be significantly up-regulated in GDM by quantitative real-time PCR (P &lt; .01), and its expression was closely related with serum estradiol level (P &lt; .05). Furthermore, miR-222 expression was significantly increased in 3T3-L1 adipocytes with a high concentration of 17β-estradiol stimulation (P &lt; .01), whereas the expressions of estrogen receptor (ER)-α protein and insulin-sensitive membrane transporter glucose transporter 4 (GLUT4) protein (P &lt; .01) were markedly reduced. In addition, ERα was shown to be a direct target of miR-222 in 3T3-L1 adipocytes by using the luciferase assay. Finally, antisense oligonucleotides of miR-222 transfection was used to silence miR-222 in 3T3-L1 adipocytes. The results showed that the expressions of ERα and GLUT4, the insulin-stimulated translocation of GLUT4 from the cytoplasm to the cell membrane and glucose uptake in mature adipocytes were dramatically increased (P &lt; .01). In conclusion, miR-222 is a potential regulator of ERα expression in estrogen-induced insulin resistance in GDM and might be a candidate biomarker and therapeutic target for GDM.

To study the genetic effect of gestational diabetes mellitus by study IRS1gene expression in female with Gestational diabetes mellitus. It is characterized high level of blood glucose, especially during first trimester then increased during the 2nd and 3rd trimester of the pregnancy period. The blood samples taken from one hundred twenty healthy women and female with gestational diabetes mellitus in 3rd trimester period of pregnancy, level of fasting blood glucose (FBG) also HbA1c% measured to diagnose GDM, in addition to lipid profile (cholesterol, triglyceride, HDL, LDL, and VLDL), molecular study consist of RNA extraction and qRT- PCR for IRS1gene expression determination. The fasting blood glucose mg/dl and HbA1c% level was increased highly significantly (P<0.01) between patients and control (healthy women) in 3rd trimester stage in addition lipid profile included )serum cholesterol, serum triglyceride, LDL and VLDL( (mg/dl) but level of HDL (mg/dl) was decreased highly significantly (P<0.01) between patients and control. The result showed high significant of IRS1 expression gene in control (1.00 ± 0.00) while in patients (0.147 ± 0.02). The low expression of IRS1 gene was connected with gestational diabetes mellitus comparison in control (healthy women) in Iraqi female in third trimester of pregnancy

Abstract Background Gestational diabetes mellitus (GDM), a common endocrine disorder with rising prevalence in pregnancy, has been reported to be associated with alteration of gut microbiota in recent years. However, the role of gut microbiome in GDM physiopathology remains unclear. This pilot study aims to characterize the alteration of gut microbiota in GDM on species-level resolution and evaluate the relationship with occurrence of GDM. Methods An analysis based on 16S rRNA microarray was performed on fecal samples obtained from 30 women with GDM and 28 healthy pregnant women. Results We found 54 and 141 differentially abundant taxa between GDM and control group at the genus and the species level respectively. Among GDM patients, Peptostreptococcus anaerobius was inversely correlated with fasting glucose while certain species (e.g., Aureimonas altamirensis, Kosakonia cowanii) were positively correlated with fasting glucose. Conclusions This study suggests that there are large amounts of differentially abundant taxa between GDM and control group at the genus and the species level. Some of these taxa were correlated with blood glucose level and might be used as biomarkers for diagnoses and therapeutic targets for probiotics or synbiotics.
