Abstract
OBJECTIVE To explore the application value of intravitreal injection of Conbercept (IVC)-assisted pars plana vitrectomy (PPV) in patients with severe proliferative diabetic retinopathy (PDR). METHODS Forty-eight patients with severe PDR who underwent surgical treatment in Chongqing Aier Eye Hospital between October 2019 and June 2021 were retrospectively enrolled, and their clinical data were analyzed. Of them, 22 patients receiving PPV alone were assigned to the PPV group, and the remaining 26 patients treated with IVC-assisted PPV were included in the PPV+IVC group. The intra-operative indicators, postoperative complication rate, visual acuity (VA) improvement, and postoperative quality of life (QoL) were compared between the two groups. The levels of vascular endothelial growth factor (VEGF), placental growth factor (PIGF), and basic fibroblast growth factor (bFGF) in aqueous humor (AH) as well as serum contents of interleukin-6 (IL-6), interleukin-1β (IL-1β), and tumor necrosis factor-α (TNF-α) were determined by Enzyme Linked Immunosorbent Assay (ELISA). RESULTS Compared to the PPV group, the operation time of the PPV+IVC group was significantly shorter, and the incidence of severe intraoperative blood loss (IBL), bipolar electrocoagulation hemostasis, iatrogenic retinal breaks (IRBs), postoperative silicone oil tamponade (SOT), and overall complications were significantly reduced. After surgery, the central macular thickness (CMT) was lower and the best corrected visual acuity (BCVA) assessed by the standard visual acuity chart and VA were significantly more improved in the PPV+IVC group versus the PPV group. After the use of Conbercept, the AH levels of VEGF, PIGF, and bFGF in the PPV+IVC group decreased and were significantly lower than those in the PPV group. The PPV+IVC group also showed lower serum levels of TNF-α, IL-6, and IL-1β than the PPV group. CONCLUSIONS IVC-assisted PPV can effectively reduce the difficulty of surgical treatment for PDR, better improve the postoperative VA of patients, and reduce inflammation with fewer complications.

Abstract
PURPOSE We sought to reveal the expression profiles of transfer RNA-derived small RNAs (tsRNAs) and microRNAs (miRNAs) in the vitreous humor of patients with proliferative diabetic retinopathy (PDR). METHODS Vitreous humor samples were obtained from PDR patients and a control group for this study. Sequencing of small RNAs was conducted to assess the expression profiles of tsRNAs and miRNAs in both groups, which was followed by validation using reverse transcription-quantitative real-time polymerase chain reaction (RT-qPCR). Bioinformatics analyses were conducted to predict the target genes and their potential biological functions and signaling pathways. RESULTS A total of 37 tsRNAs and 70 miRNAs with significant differences were screened out from the vitreous humor samples of PDR patients compared to controls. Following validation by RT-qPCR, the target genes of the validated tsRNAs and miRNAs were predicted, and Gene Ontology analysis indicated that the target genes of the tsRNAs were most enriched in the cellular macromolecule metabolic process, cytoplasm, and ion-binding, while those of the miRNAs were most abundant in the regulation of major metabolic process, cytoplasm, and protein-binding. In addition, Kyoto Encyclopedia of Genes and Genomes pathway analysis showed that the target genes of said tsRNAs and miRNAs were most enriched in the adenosine monophosphate-activated protein kinase signaling pathway and Th17 cell differentiation, respectively. CONCLUSIONS The present study identified altered tsRNAs and miRNAs in vitreous humor samples of PDR patients, which may play important roles in the pathogenesis of PDR and could be considered potential therapeutic targets in the treatment of PDR.

Abstract
CLINICAL RELEVANCE MicroRNAs (miRNAs) have been reported to be involved in the progression of various diseases. Studying the regulatory mechanisms of miRNAs can help clinical treatment. BACKGROUND Diabetic retinopathy (DR) is one of the complications of diabetes. The objective of this study was to elucidate the underlying molecular mechanisms by which miR-200c-3p regulates the pyroptosis of DR cell. METHODS Human retinal microvascular endothelial cells (HRMECs) and high glucose (HG) cultures established DR cell model in vitro. RT-qPCR is used to detect the expression level of miRNAs. CCK-8 assays and flow cytometry are used to detect apoptosis of HRMECs cell. Western blotting is used to detect cleaved caspase-3, cleaved caspase-1, and N-GSDMD proteins levels in HRMECs. The ELISA assay is used to detect the expression of IL-1β and IL-18. Predict and validate potential binding sites between miR-200c-3p and SLC30A7 by dual luciferase reporter gene analysis. RESULTS The results showed that HG caused damage to HRMECs through the pyroptosis pathway rather than the apoptosis pathway. MiR-200c-3p is highly expressed in HG induced-HRMECs, and knockdown of miR-200c-3p mitigates HG-induced HRMECs pyroptosis. MiR-200c-3p negatively targets SLC30A7 in HRMECs, and miR-200c-3p regulates pyroptosis of HG-induced HRMECs by targeting SLC30A7. CONCLUSION The results suggest that miR-200c-3p might be a promising interference target for DR prevention and treatment. The results of current study may provide new insights into development of therapeutic strategies for DR.

Abstract
PURPOSE Diabetic retinopathy (DR), the leading cause of blindness among working adults, is an urgent public health problem as diabetes mellitus (DM) is increasing at an alarming rate. Hyperglycemia-induced endothelial dysfunction is the principal contributing factor leading to the development of microangiopathy. Altered levels of microRNA (miR), the negative regulator of protein-coding genes, have been observed and considered to be markers for DR. Present study aimed to find out whether miR levels in plasma could be effective biomarkers to differentiate between type 2 diabetes mellitus (T2DM) with non-proliferative retinopathy (NPDR) from T2DM with no-DR (DNR). METHODS We recruited 50 T2DM subjects comprising 31 NPDR and 19 DNR individuals. Surrogate markers of systemic oxidative stress and vascular endothelial growth factor (VEGF) were measured in plasma. Levels of miR-126 and miR-132 were determined in plasma and vitreous fluid using real-time PCR. RESULTS We observed that levels of miR-126 and miR-132 were decreased in NPDR subjects in comparison to DNR. Plasma levels of miRs were inversely correlated with secreted levels of VEGF and oxidative stress marker. The levels of these miRs showed discriminating ability between NPDR and DNR. CONCLUSION Circulating miRs 126 and 132 in plasma or vitreous may serve as biomarkers for early diabetic retinopathy risk prediction, provided validated in a larger cohort and other forms of retinal vasculopathy or retinopathy in the future.

MicroRNA Sequencing Analysis in Obstructive Sleep Apnea and Depression: Anti-Oxidant and MAOA-Inhibiting Effects of miR-15b-5p and miR-92b-3p through Targeting PTGS1-NF-κB-SP1 Signaling. Antioxidants (Basel) 2021; 10:antiox10111854.

Abstract
The aim of this study was to identify novel microRNAs related to obstructive sleep apnea (OSA) characterized by intermittent hypoxia with re-oxygenation (IHR) injury. Illumina MiSeq was used to identify OSA-associated microRNAs, which were validated in an independent cohort. The interaction between candidate microRNA and target genes was detected in the human THP-1, HUVEC, and SH-SY5Y cell lines. Next-generation sequencing analysis identified 22 differentially expressed miRs (12 up-regulated and 10 down-regulated) in OSA patients. Enriched predicted target pathways included senescence, adherens junction, and AGE-RAGE/TNF-α/HIF-1α signaling. In the validation cohort, miR-92b-3p and miR-15b-5p gene expressions were decreased in OSA patients, and negatively correlated with an apnea hypopnea index. PTGS1 (COX1) gene expression was increased in OSA patients, especially in those with depression. Transfection with miR-15b-5p/miR-92b-3p mimic in vitro reversed IHR-induced early apoptosis, reactive oxygen species production, MAOA hyperactivity, and up-regulations of their predicted target genes, including PTGS1, ADRB1, GABRB2, GARG1, LEP, TNFSF13B, VEGFA, and CXCL5. The luciferase assay revealed the suppressed PTGS1 expression by miR-92b-3p. Down-regulated miR-15b-5p/miR-92b-3p in OSA patients could contribute to IHR-induced oxidative stress and MAOA hyperactivity through the eicosanoid inflammatory pathway via directly targeting PTGS1-NF-κB-SP1 signaling. Over-expression of the miR-15b-5p/miR-92b-3p may be a new therapeutic strategy for OSA-related depression.

Abstract
MicroRNAs are a large group of small noncoding RNAs that work in multiple cellular pathways. miR-204, as one of the key axes in the development, maintenance, and pathogenesis of the retina, plays several roles by modulating its target genes. This study was aimed at evaluating the target genes of miR-204 involved in the development and progression of common retinopathies such as glaucoma, retinoblastoma, and age-related macular degeneration. In this study, three datasets related to retinopathies (GSE50195, GSE27276, and GSE97508) were selected from Gene Expression Omnibus. miR-204 target genes were isolated from TargeScan. The shares between retinopathy and miR-204 target genes were then categorized. Using Enrichr and STRING, we highlighted the signaling pathways and the relationships between the proteins. SHC1 events in ERBB2, adherent junction's interactions, NGF signaling via TRKA from the plasma membrane, IRF3-mediated activation of type 1 IFN, pathways in upregulated genes and G0 and early G1, RORA-activated gene expression, PERK-regulated gene expression, adherent junction's interactions, and CREB phosphorylation pathways in downregulated genes were identified in glaucoma, retinoblastoma, and age-related macular degeneration. WEE1, SMC2, HMGB1, RRM2, and POLA1 proteins were also observed to be involved in the progression and invasion of retinoblastoma; SLC24A2 and DTX4 in age-related macular degeneration; and EPHB6, EFNB3, and SHC1 in glaucoma. Continuous bioinformatics analysis has shown that miR-204 has a significant presence and expression in retinal tissue, and approximately 293 genes are controlled and regulated by miR-204 in this tissue; also, target genes of miR-204 have the potential to develop various retinopathies; thus, a study of related target genes can provide appropriate treatment strategies in the future.

Abstract
Neuropilin-1 is a transmembrane glycoprotein that has been implicated in several processes including angiogenesis and immunity. Recent evidence has also shown that it is implied in the cellular internalization of the severe acute respiratory syndrome coronavirus (SARS-CoV-2), which causes the coronavirus disease 2019 (COVID-19). We hypothesized that specific microRNAs can target Neuropilin-1. By combining bioinformatic and functional approaches, we identified miR-24 as a regulator of Neuropilin-1 transcription. Since Neuropilin-1 has been shown to play a key role in the endothelium-mediated regulation of the blood-brain barrier, we validated miR-24 as a functional modulator of Neuropilin-1 in human brain microvascular endothelial cells (hBMECs), which are the most suitable cell line for an in vitro bloodâ€"brain barrier model.

Abstract
The two main co-factors needed by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) to enter human cells are angiotensin-converting enzyme 2 (ACE2) and transmembrane protease serine 2 (TMPRSS2). Here, we focused on the study of microRNAs that specifically target TMPRSS2. Through a bioinformatic approach, we identified miR-98-5p as a suitable candidate. Since we and others have shown that endothelial cells play a pivotal role in the pathogenesis of the coronavirus disease 2019 (COVID-19), we mechanistically validated miR-98-5p as a regulator of TMPRSS2 transcription in two different human endothelial cell types, derived from the lung and from the umbilical vein. Taken together, our findings indicate that TMPRSS2 represents a valid target in COVID-19 treatment, which may be achieved by specific non-coding-RNA approaches.
