microRNAs in newborns with low birth weight: relation to birth size and body composition. Pediatr Res 2022; 92:829-837. [PMID: 34799665 DOI: 10.1038/s41390-021-01845-4] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/02/2021] [Revised: 10/15/2021] [Accepted: 10/28/2021] [Indexed: 11/08/2022]
Abstract
BACKGROUND Children with low birth weight (LBW) have a higher risk of developing endocrine-metabolic disorders later in life. Deregulation of specific microRNAs (miRNAs) could underscore the programming of adult pathologies. We analyzed the miRNA expression pattern in both umbilical cord serum samples from LBW and appropriate-for-gestational-age (AGA) newborns and maternal serum samples in the 3rd trimester of gestation, and delineated the relationships with fetal growth, body composition, and markers of metabolic risk. METHODS Serum samples of 12 selected mother-newborn pairs, including 6 LBW and 6 AGA newborns, were used for assessing miRNA profile by RNA-sequencing. The miRNAs with differential expression were validated in a larger cohort [49 maternal samples and 49 umbilical cord samples (24 LBW, 25 AGA)] by RT-qPCR. Anthropometric, endocrine-metabolic markers and body composition (by DXA) in infants were determined longitudinally over 12 months. RESULTS LBW newborns presented reduced circulating concentrations of miR-191-3p (P = 0.015). miR-191-3p levels reliably differentiated LBW from AGA individuals (ROC AUC = 0.76) and were positively associated with anthropometric and body composition measures at birth and weight Z-score at 12 months (P < 0.05). CONCLUSIONS miR-191-3p was reliably different in LBW individuals, and could be a new player in the epigenetic mechanisms linking LBW and future endocrine-metabolic adverse outcomes. IMPACT Children with low birth weight (LBW) have a higher risk of developing endocrine-metabolic disorders. Deregulation of specific microRNAs (miRNAs) could underscore the programming of those pathologies. miR-191-3p is downregulated in serum of LBW newborns, and its concentrations associate positively with neonatal anthropometric measures, with lean mass and bone accretion at age 15 days and with weight Z-score at age 12 months. miR-191-3p was reliably different in individuals with LBW, and could be a new player in the epigenetic mechanisms connecting LBW and future endocrine-metabolic adverse outcomes.

Circular RNA profiles and the potential involvement of down-expression of hsa_circ_0001360 in cutaneous squamous cell carcinogenesis. FEBS Open Bio 2021; 11:1209-1222. [PMID: 33569895 PMCID: PMC8016141 DOI: 10.1002/2211-5463.13114] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2020] [Revised: 12/27/2020] [Accepted: 02/08/2021] [Indexed: 12/13/2022] Open
Abstract
Circular RNAs (circRNAs) act as sponges of noncoding RNAs and have been implicated in many pathophysiological processes, including tumor development and progression. However, their roles in cutaneous squamous cell carcinoma (cSCC) are not yet well understood. This study aimed to identify differentially expressed circRNAs and their potential functions in cutaneous squamous cell carcinogenesis. The expression profiles of circRNAs in three paired cSCC and adjacent nontumorous tissues were detected with RNA sequencing and bioinformatics analysis. The candidate circRNAs were validated by PCR, Sanger sequencing and quantitative RT‐PCR in another five matched samples. The biological functions of circRNAs in SCL‐1 cells were assessed using circRNA silencing and overexpression, 3‐(4,5‐dimethylthiazol‐2‐yl)‐5‐(3‐carboxymethoxyphenyl)‐2‐(4‐sulfophenyl)‐2H‐tetrazolium inner salt (MTS), flow cytometry, transwell and colony formation assays. In addition, the circRNA–miRNA–mRNA interaction networks were predicted by bioinformatics. In summary, 1115 circRNAs, including 457 up‐regulated and 658 down‐regulated circRNAs (fold change ≥ 2 and P < 0.05), were differentially expressed in cSCC compared with adjacent nontumorous tissues. Of four selected circRNAs, two circRNAs (hsa_circ_0000932 and hsa_circ_0001360) were confirmed to be significantly decreased in cSCC using PCR, Sanger sequencing and quantitative RT‐PCR. Furthermore, hsa_circ_0001360 silencing was found to result in a significant increase of the proliferation, migration and invasion but a significant decrease of apoptosis in SCL‐1 cells in vitro, whereas hsa_circ_0001360 overexpression showed the opposite regulatory effects. hsa_circ_0001360 was predicted to interact with five miRNAs and their corresponding genes. In conclusion, circRNA dysregulation may play a critical role in carcinogenesis of cSCC, and hsa_circ_0001360 may have potential as a biomarker for cSCC.

Abstract
OBJECTIVE Brain microvascular endothelial cells (BMECs) are involved in brain vascular dysfunction in ischemic stroke. Abnormal expression of circular RNAs regulate physiological and pathophysiological processes in the central nervous system. The aim of the present study was to investigate profile circRNAs in human BMECs after oxygen glucose deprivation (OGD), which was an in vitro model of ischemic stroke, and find promising biomarkers in ischemic stroke. METHODS RNA sequencing (RNA-seq) technology was conducted to analyze the differential expression of circRNAs between BMECs after OGD and non-OGD treated BMECs. RT-qPCR, cell proliferation, cell apoptosis and dual-luciferase assay, and so on, were used to investigate the functions and molecular mechanisms of hsa_circ_0001360 (named circPHC3 in this study) in ischemic stroke. RESULTS CircPHC3 was highly expressed in human BMECs after OGD. Knockdown of circPHC3 inhibited cell death and apoptosis in human BMECs treated with OGD. Mechanistically, circPHC3 acted as miR-455-5p sponge to activate TRAF3 to promote cell death and apoptosis in human BMECs after OGD. CONCLUSION In short, circPHC3 promotes cell death and apoptosis in ischemic stroke in vitro model, which might be a novel molecular target for acute cerebrovascular protection.

Hsa_circularRNA_0079201 suppresses chondrocyte proliferation and endochondral ossification by regulating the microRNA‑140‑3p/SMAD2 signaling pathway in idiopathic short stature. Int J Mol Med 2020; 46:1993-2006. [PMID: 33125098 PMCID: PMC7595675 DOI: 10.3892/ijmm.2020.4737] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2020] [Accepted: 08/11/2020] [Indexed: 12/29/2022] Open
Abstract
Circular (circ)RNAs are an important group of non‑coding RNAs involved in different pathological and physiological functions, such as longitudinal bone growth. However, the effects of an increase or decrease in circRNA expression on idiopathic short stature (ISS) remain largely unknown. The present study compared the circRNA expression patterns of patients with ISS and healthy individuals to identify differentially expressed circRNAs involved in the regulation of ISS pathogenesis and their target microRNAs (miR). Microarray analysis revealed that 145 circRNAs were differentially expressed in patients with ISS, including 83 up‑ and 62 downregulated circRNAs. Reverse transcription‑quantitative PCR confirmed that hsa_circRNA_0079201 was increased in patients with ISS compared with that in the normal individuals, whilst hsa_circRNA_0079201 overexpression in human chondrocytes was shown to significantly suppress their proliferation, hypertrophy and endochondral ossification abilities. Luciferase reporter assays identified that circRNA_0079201 acted as an miR‑140‑3p sponge. In situ hybridization confirmed the co‑localization of circRNA_0079201 and miR‑140‑3p in the human chondrocyte and neonatal femur growth plate of C57 mice, while rescue experiments demonstrated that miR‑140‑3p overexpression reversed the inhibition of human chondrocyte proliferation, hypertrophy and endochondral ossification, caused by circRNA_0079201 overexpression. Bioinformatics analysis and luciferase reporter assays revealed that SMAD2 was a potential target gene of miR‑140‑3p. Furthermore, overexpressing circRNA_0079201 in human chondrocytes suppressed miR‑140‑3p and increased SMAD2 protein expression level. Taken together, chondrocyte proliferation, hypertrophy and endochondral ossification in ISS was suppressed by a novel regulatory axis consisting of the hsa_circRNA_0079201/miR‑140‑3p/SMAD2 pathway. The present study provided evidence that hsa_circRNA_0079201 may be a potential target for ISS therapy.

Abstract
Circular RNAs (circRNAs), a novel type of endogenous RNAs, can function as microRNA (miRNA) sponges capable of regulating gene transcription, binding to RNA-associated proteins, and even encoding proteins. CircRNAs are involved in various cell behaviors, such as proliferation and apoptosis. The mouse model has also been demonstrated to be similar to that of humans in many studies. To explore the profile of circRNAs during embryonic lung development and their potential functions in lung development-related diseases, mouse embryos at the pseudoglandular phase, canalicular phase, saccular phase, and alveolar phase were collected. High-throughput sequencing was then used to identify a total of 1,735 circRNAs (junction reads ≥5 and p < 0.05). It is well known that the functions of circRNAs are related to host genes. In our study, bioinformatics analysis indicated that the screened host genes were closely associated with lung development and included the Hippo signaling pathway, PI3K-Akt signaling pathways, and TGF-β signaling pathways. Moreover, miRNA sponges are another mechanism involved in lung development. Therefore, we predicted many miRNAs binding to circRNAs, such as miR-17 and miR-20, using the TargetScan and miRanda databases. Previously, miRNAs were proven to be necessary for lung development. The peak expression of circRNAs is distributed at different time points, suggesting their involvement in different stages of embryonic mouse lung development.
