The role of 25(OH)D3 and circRNAs in early diagnosis of gestational diabetes mellitus

Abstract

Objective: To explore the relationship between 25(OH)D3 and circular RNAs (circR-NAs) in the early diagnosis of gestational diabetes mellitus (GDM) and to screen for biological markers for early prediction of GDM.Methods: A cohort study was conducted using samples and data collected from pregnant women registered at the Li Huili hospital in China between April 2018 and January 2020. Four circRNAs (hsa_circ_0003218, hsa_circ_0002968, hsa_circ_0007430, and hsa_circ_0006260) were selected as potential biomarkers, and quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR) was used to measure their concentration in the serum and to analyze their correlation with 25(OH)D3. The Pearson correlation test was used to assess the correlation between the 25(OH)D3, circRNAs, and various clinical variables. The area under the receiver operating characteristic (ROC) curve was used to assess the diagnostic value of circRNAs and 25(OH)D3 in the early stage of pregnancy. Results: Weight, body mass index (BMI), triglycerides, total cholesterol, high-density lipoprotein cholesterol (HDL-C), and 25(OH)D3 were found to be risk factors for GDM. The level of 25(OH)D3 correlated significantly with HDL-C with a correlation coefficient of 0.298 (p < 0.05). The expression of hsa_circ_0003218 was significantly downregulated in the GDM group (p < 0.05). Hsa_circ_0002968, hsa_circ_0007430, and hsa_circ_0006260 did not show any differential expression between the two groups (p > 0.05). Furthermore, hsa_circ_0003218 level correlated significantly with 25(OH)D3 and the correlation coefficient was 0.357 (p < 0.05). The AUC of hsa_ circ_0003218 combined with 25(OH)D3 was 0.789 ([0.700-0.877], p < 0.001), with sensitivity and specificity of 63.04% and 80.65%, respectively. Conclusions: Hsa_circ_0003218 and 25(OH)D3 may jointly participate in the metabolic process of GDM. Thus, the combination of 25(OH)D3 and hsa_circ_0003218 represents a potential biomarker for the prediction of GDM in the early stages of pregnancy.

The role of ncRNA regulatory mechanisms in diseases—case on gestational diabetes

“…hsa_circ_0003218 was significantly correlated with the GDM risk factor 25(OH)D3, and the two may be jointly involved in the metabolic process of GDM. Therefore, their combination can be used as a predictive marker for the early stage of GDM [ 89 ].…”
