Abstract
MiRNAs are related to neuronal proliferation and apoptosis following cerebral ischemia-reperfusion injury (CIRI). This study focused on miR-30c-5p in the disease. An oxygen-glucose deprivation/re-oxygenation (OGD/R) model was prepared in HT22 cells and transfected to overexpress miR-30c-5p and G Protein Subunit Alpha I2 (GNAI2) respectively or co-transfected to silence miR-30c-5p and GNAI2. Meanwhile, a middle cerebral artery occlusion (MCAO) model was constructed in mice, and miR-30c-5p and GNAI2 were silenced in vivo simultaneously. The mice were evaluated for neurological damage, apoptosis, and inflammation. HT22 cells were tested for cytotoxicity, proliferation, apoptosis, and inflammatory factors. The interaction between miR-30c-5p and GNAI2 was predicted, analyzed, and confirmed. MiR-30c-5p was found to be downregulated in both experimental models. miR-30c-5p reduced lactate dehydrogenase production, inflammatory response, inhibit apoptosis, and enhanced neuronal proliferation, while GNAI2 overexpression showed the opposite results. Downregulated miR-30c-5p worsened neurological function, apoptosis, and inflammation of MCAO mice while silencing GNAI2 attenuated the influence of downregulated miR-30c-5p. MiR-30c-5p can improve neuronal apoptosis and inflammatory response caused by CIRI and is neuroprotective by targeting GNAI2, providing a new target for treating CIRI.

Abstract
Polycystic ovary syndrome (PCOS) is a systemic endocrine disease affecting women's reproductive health. Ovarian angiogenesis in PCOS patients is abnormal, manifested by increased ovarian stromal vascularization and upregulated proangiogenic factors such as vascular endothelial growth factor (VEGF). However, the specific mechanisms underlying these changes in PCOS remain unknown. In this study, we induced the adipogenic differentiation in preadipocyte 3T3-L1 cells and found that adipocyte-derived exosomes promoted proliferation, migration, tube formation, and VEGFA expression in human ovarian microvascular endothelial cells (HOMECs) by delivering miR-30c-5p. Mechanistically, dual luciferase reporter assay demonstrated that miR-30c-5p directly targeted the 3'- untranslated region (UTR) of suppressor of cytokine signaling 3 (SOCS3) mRNA. In addition, adipocyte-derived exosomal miR-30c-5p activated signal transducer and activator of transcription 3 (STAT3)/VEGFA pathway in HOMECs via targeting SOCS3. In vivo experiments indicated that tail vein injection of adipocyte-derived exosomes exacerbated endocrine and metabolic disorders and ovarian angiogenesis in mice with PCOS via miR-30c-5p. Taken together, the study revealed that adipocyte-derived exosomal miR-30c-5p promotes ovarian angiogenesis via the SOCS3/STAT3/VEGFA pathway, thereby participating in the development of PCOS.

Abstract
Atherosclerosis (AS) is the basic lesion underlying the occurrence and development of cerebrovascular diseases. Abnormal proliferation of vascular smooth muscle cells (VSMCs) plays a crucial role in AS. We aimed to explore the role of SNHG16 in AS and the molecular mechanism of VSMC involvement in the regulation of AS. The expression levels of SNHG16, miR-30c-5p and SDC2 were detected by qRT-PCR. CCK-8, wound healing and Transwell assays were used to assess ox-LDL-induced VSMC proliferation, migration, and invasion, respectively. Western blot analysis was used to detect SDC2 and MEK/ERK pathway-related protein levels. A dual-luciferase reporter assay confirmed the binding of SNHG16 with miR-30c-5p and miR-30c-5p with SDC2. SNHG16 and SDC2 expression was upregulated in patients with AS and ox-LDL-induced VSMCs, while miR-30c-5p was downregulated. Ox-LDL-induced VSMC proliferation and migration were increased, and the MEK/ERK signalling pathway was activated. MiR-30c-5p was targeted to SNHG16 and SDC2. Downregulating SNHG16 or upregulating miR-30c-5p inhibited ox-LDL-induced VSMC proliferation and migration and inhibited MEK/ERK signalling pathway activation. In contrast, downregulating miR-30c-5p or upregulating SDC2 reversed the effects of downregulating SNHG16 or upregulating miR-30c-5p. Furthermore, downregulating SDC2 inhibited ox-LDL-induced proliferation and migration of VSMCs and inhibited activation of the MEK/ERK signalling pathway, while upregulating lncRNA SNHG16 reversed the effects of downregulating SDC2. Downregulation of SNHG16 inhibited VSMC proliferation and migration in AS by targeting the miR-30c-5p/SDC2 axis. This study provides a possible therapeutic approach to AS.

Abstract
Background As the most important component of the vascular wall, vascular smooth muscle cells (VSMCs) participate in the pathological process by phenotype transformation or differentiation from stem/progenitor cells. The main purpose of this study was to reveal the role and related molecular mechanism of microRNA-30c-5p (miR-30c-5p) in VSMC differentiation from adventitial progenitor cells expressing stem cell antigen-1(Sca-1). Methods In this study, we detected the expression of miR-30c-5p in human normal peripheral arteries and atherosclerotic arteries. In vitro, a stable differentiation model from adventitial Sca-1+ progenitor cells to VSMCs was established using transforming growth factor-β1 (TGF-β1) induction and the expression of miR-30c-5p during the process was observed. Then, we explored the effect of miR-30c-5p overexpression and inhibition on the differentiation from adventitial Sca-1+ progenitor cells to VSMCs. The target genes of miR-30c-5p were identified by protein chip and biological analyses and the expression of these genes in the differentiation process were detected. Further, the relationship between the target gene and miR-30c-5p and its effect on differentiation were evaluated. Finally, the co-transfection of miR-30c-5p inhibitor and small interfering RNA (siRNA) of the target gene was implemented to verify the functional target gene of miR-30c-5p during the differentiation from adventitial Sca-1+ progenitor cells to VSMCs, and the dual-luciferase reporter gene assay was performed to detect whether the mRNA 3′untranslated region (UTR) of the target gene is the direct binding site of miR-30c-5p. Results The expression of miR-30c-5p in the human atherosclerotic arteries was significantly lower than that in the normal arteries. During the differentiation from adventitial Sca-1+ progenitor cells to VSMCs, the expression of VSMC special markers including smooth muscle α-actin (SMαA), smooth muscle-22α (SM22α), smooth muscle myosin heavy chain (SMMHC), and h1-caponin increased accompanied with cell morphology changing from elliptic to fusiform. Meanwhile, the expression of miR-30c-5p decreased significantly. In functional experiments, overexpression of miR-30c-5p inhibited SMαA, SM22α, SMMHC, and h1-caponin at the mRNA and protein levels. In contrast, inhibition of miR-30c-5p promoted the expression of SMαA, SM22α, SMMHC, and h1-caponin. The target gene, osteoprotegerin (OPG), was predicted through protein chip and bioinformatics analyses. Overexpression of miR-30c-5p inhibited OPG expression while inhibition of miR-30c-5p had an opposite effect. Co-transfection experiments showed that low expression of OPG could weaken the promotion effect of miR-30c-5p inhibitor on the differentiation from adventitial Sca-1+ progenitor cells to VSMCs and the dual-luciferase reporter gene assay demonstrated that miR-30c-5p could target the mRNA 3′UTR of OPG directly. Conclusions This study demonstrates that miR-30c-5p expression was significantly decreased in atherosclerotic arteries and miR-30c-5p inhibited VSMC differentiation from adventitial Sca-1+ progenitor cells through targeting OPG, which may provide a new target for the treatment of VSMCs-associated diseases.

Abstract
Multiple system atrophy (MSA) is a neurodegenerative disease that belongs to the α synucleinopathies. Clinically, there is an overlap between MSA and Parkinson's disease (PD), especially at the early disease stage. However, these two pathologies differ in terms of disease progression. Currently, no biomarker exists to differentiate MSA from PD. MicroRNAs are non-coding RNAs implicated in gene expression regulation. MiRNAs modulate cellular activity and they control a range of physiological and pathological functions. miRNAs are found in biofluids, such as blood, serum, plasma, saliva, and cerebrospinal fluid. Many groups, including ours, found that circulating miRNAs are differently expressed in blood, plasma, serum and cerebrospinal fluid of PD and MSA patients. In the present study, our primary aim was to determine if serum mir-30-5p and mir-148b-5p can be used as biomarkers for early diagnosis of PD and/or MSA. Our secondary goal was to determine if serum levels of those miRNAs can be correlated with the patients' clinical profile. Using quantitative PCR (qPCR), we evaluated expression levels of miR-30c-5p and miR148b-5p in serum samples from PD (n = 56), MSA (n = 49), and healthy control (n = 50) subjects. We have found that miR-30c-5p is significantly upregulated in MSA if compared with PD and healthy control subjects. Moreover, serum miR-30c-5p levels correlate with disease duration in both MSA and PD. No significant difference was found in miR-148b-5p among MSA, PD and healthy control subjects. Our results suggest a possible role of serum miR-30-5p as a biomarker for diagnosis and progression of MSA.

Abstract
BACKGROUND In China, gastric cancer (GC) is an ordinary malignant tumor. Recent literatures have shown that microRNA is critical during tumorigenesis. This study focuses on the influence of miR-30c-5p on the metastasis of GC and further explores its underlying mechanism. METHODS Before the study, expression level of miR-30c-5p and targeted protein was detected in 40 GC tissue samples and 5 GC cells by RT-qPCR. Meanwhile, correlation analysis was conducted between miR-30c-5p expression level and clinicopathological features. In addition, wound healing assay and cell invasion assay were utilized to identify whether miR-30c-5p could affect the migrated and invaded ability of GC cells. Western blotting assay and luciferase assay were used to explore the potential mechanism. RESULTS In GC tissues, miR-30c-5p expression level was significantly lower and was remarkably related with clinical features such as tumor node metastasis(TNM) stage and lymphatic metastasis. Moreover, the migrated and invaded ability of GC cells was enhanced through knockdown of miR-30c-5p, while overexpression of miR-30c-5p presented with reversed effect. Further study showed that miR-30c-5p inhibited the expression of its target spot, metastasis-associated protein 1(MTA1), and then suppressed the process of epithelial to mesenchymal transition(EMT) which was important in the metastasis of GC. CONCLUSION The results indicate that miR-30c-5p, a novel suppressor in tumorigenesis, could inhibit the metastasis and EMT via MTA1, which may offer a possible therapeutic target in GC.
