Abstract
Preterm delivery is a common complication of pregnancy which leads to significant neonatal mortality and morbidity. Identifying predictive markers linked to spontaneous preterm delivery (SPTD) is important for effective treatment and prevention of PTD. To explore potential biomarkers related to SPTD, we performed proteomics analysis in amniotic fluid (AF). In total, we enrolled 30 pregnant women with singleton gestation who underwent clinically indicated amniocentesis at 15-24 weeks of gestation. LC-MS analysis was used to analyze the AF samples of 10 women with SPTD < 34 weeks after cervix cerclage (Preterm group), 10 women with term delivery (TD) ≥ 34 weeks after cervix cerclage (Term group), and 10 women who delivered at term (Normal group). ELISA validation was performed for candidate proteins in a second independent cohort. As a result, we identified 44 differentially expressed proteins (DEPs, P < 0.05) via proteomic analysis, and based on that, 9 primary pathways were also determined in SPTD. Results of the ELISA assay confirmed that the increased concentration of Serpin A1, decreased concentrations of Renin and IGFBP4 were significantly associated with SPTD at ≤34 weeks.

Abstract
Background Preterm birth (PTB) is a multifactorial syndrome that seriously threatens the health of pregnant women and babies worldwide. Recently, circular RNAs (circRNAs) have been understood as important regulators of various physiological and pathological processes. However, the expression pattern and potential roles of circRNAs in PTB are largely unclear. Methods In this study, we extracted and analyzed the circRNA expression profiles in maternal and fetal samples of preterm and term pregnancies, including maternal plasma, maternal monocytes, myometrium, chorion, placenta, and cord blood. We identified the circRNAs which is associated with PTB in different tissues and explored their relationships from the perspective of the overall maternal-fetal system. Furthermore, co-expression analysis of circRNAs and mRNAs, target microRNAs (miRNAs), and RNA-binding proteins (RBPs), provided new clues about possible mechanisms of circRNA function in PTB. In the end, we investigated the potential special biofunctions of circRNAs in different tissues and their common features and communication in PTB. Results Significant differences in circRNA types and expression levels between preterm and term groups have been proved, as well as between tissues. Nevertheless, there were still some PTB-related differentially expressed circRNAs (DECs) shared by these tissues. The functional enrichment analysis showed that the DECs putatively have important tissue-specific biofunctions through their target miRNA and co-expressed mRNAs, which contribute to the signature pathologic changes of each tissue within the maternal-fetal system in PTB (e.g., the contraction of the myometrium). Moreover, DECs in different tissues might have some common biological activities, which are mainly the activation of immune-inflammatory processes (e.g., interleukin1/6/8/17, chemokine, TLRs, and complement). Conclusions In summary, our data provide a preliminary blueprint for the expression and possible roles of circRNAs in PTB, which lays the foundation for future research on the mechanisms of circRNAs in PTB.

[PMID: 35034256 DOI: 10.1007/s11010-021-04305-z] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2021] [Accepted: 11/17/2021] [Indexed: 11/29/2022]
Abstract
Therapeutic inhibition of hypoxia-inducible factor-1alpha (HIF-1α) action has emerged as a potential approach for managing several diseases, including myopia. Herein, we analyzed the role of HIF-1α in the progression of pathologic myopia by regulating the miR-150-5p/LAMA4/p38 MAPK axis. Microarray-based gene expression profiling of pathologic myopia was employed to identify differentially expressed genes. Human scleral fibroblasts (HSFs) were cultured under the hypoxic conditions. Interaction among HIF-1α, miR-150-5p, and LAMA4 was identified. Gain- and loss-of-function experiments were performed in hypoxia-exposed HSFs to evaluate the effect of the HIF-1α/miR-150-5p/LAMA4/p38 MAPK axis on the extracellular matrix (ECM) degradation of HSFs and the subsequent pathologic myopia progression. Increased LAMA4 but decreased miR-150-5p was found in serum sample of pathologic myopia patients. HIF-1α and LAMA4 were abundantly expressed, and p38 MAPK was activated while miR-150-5p was weakly expressed in hypoxia-exposed HSFs. HIF-1α was enriched in the promoter region of miR-150-5p and downregulated its expression, thus repressing the ECM degradation of HSFs as shown by increased COL1A1 and TIMP-2 and reduced MMP2. In addition, LAMA4 was a downstream target of miR-150-5p and under the negative regulation by miR-150-5p. Overexpression of miR-150-5p promoted the ECM degradation of HSFs by inhibiting LAMA4 expression and p38 MAPK signaling pathway. However, upregulation of LAMA4 reversed the promoting effect of miR-150-5p on ECM degradation of HSFs. Overall, our findings suggest that HIF-1α can decline miR-150-5p expression and facilitate LAMA4-mediated p38 MAPK signaling pathway activation, thus arresting ECM degradation of HSFs and eventually inducing pathologic myopia.
