Abstract
BACKGROUND RNA-binding proteins are revealed to play important roles during the progression of hepatocellular carcinoma (HCC). However, the regulatory mechanisms of RNA-binding protein Quaking (QKI) in the expression and role of long non-coding RNAs (lncRNAs) in HCC cells remain not well understood. METHODS Cell Counting Kit-8, wound-healing, Transwell and colony-forming assays were performed to evaluate the effects of QKI and lncRNA EGOT on proliferation and migration of HCC cells. Tumor growth of HCC was analyzed using a mouse xenograft model. Immunoprecipitation (RIP) assay was used to investigate the interaction between QKI and EGOT. RESULTS The expression of QKI was significantly upregulated in HCC tissues and the higher QKI level was significantly associated with a poorer prognosis. Overexpression of QKI promoted the proliferation, migration, and colony-forming ability of HCC cells in vitro and tumor growth of HCC in vivo. Mechanistically, QKI protein could bind to EGOT RNA and increase its expression. Inhibition of EGOT attenuated the effects of QKI on the malignant phenotypes of HCC cells. In addition, both QKI and EGOT could activate the SAPK/JNK signaling pathway in HCC cells. CONCLUSIONS Our findings indicated that QKI exerted promotive effects on the malignant phenotypes of HCC through its interaction with EGOT.

Abstract
Angiogenesis is a key process in organ and tissue morphogenesis, as well as growth during human development, and is coordinated by pro- and anti-angiogenic factors. When this balance is affected, the related physiological and pathological changes lead to disease. Long non-coding RNAs (lncRNAs) are an important class of non-coding RNAs that do not encode proteins, but play a dynamic role in regulating gene expression. LncRNAs have been reported to be extensively involved in angiogenesis, particularly tumor angiogenesis. The non-tumor aspects have received relatively little attention and summary, but there is a broad space for research and exploration on lncRNA-targeted angiogenesis in this area. In this review, we focus on lncRNAs in angiogenesis-related diseases other than tumors, such as atherosclerosis, myocardial infarction, stroke, diabetic complications, hypertension, osteoporosis, dermatosis, as well as, endocrine, neurological, and other systemic disorders. Moreover, multiple cell types have been implicated in lncRNA-targeted angiogenesis, but only endothelial cells have attracted widespread attention. Thus, we explore the roles of other cells. Finally, we summarize the potential research directions in the area of lncRNAs and angiogenesis that can be undertaken by combining cutting-edge technology and interdisciplinary research, which will provide new insights into the involvement of lncRNAs in angiogenesis-related diseases.

[PMID: 35931919 DOI: 10.1007/s10528-022-10261-0] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2021] [Accepted: 07/03/2022] [Indexed: 01/24/2023]
Abstract
Atherosclerosis (AS) is the typical cardiovascular disease, which is the main underlying inducement of cardiovascular diseases. Aberrant expression of long noncoding RNA HLA complex group 11 (HCG11) was engaged with atherosclerosis. The objective of the present research was to explore the role and the potential mechanism of HCG11 in AS. Human umbilical vein endothelial cells (HUVECs) were stimulated with oxidized low-density lipoprotein (ox-LDL) to induce the AS model in vitro. The cell viability was detected by MTT assay. Flow cytometry was performed to determine cell pyroptosis. Gene and protein levels were detected by qPCR or Western blot assay. The interaction between HCG11, miR-224-3p, and Janus kinase 1 (JAK1) was validated by dual-luciferase reporter assays. Ox-LDL treatment aggravated cell pyroptosis and inflammation in HUVECs. And the levels of HCG11 and JAK1 was enhanced in ox-LDL-induced HUVECs, while miR-224-3p expression was reduced. Additionally, knockdown of HCG11 or miR-224-3p overexpression reversed the ox-LDL-induced cell viability decline and the increase of cell pyroptosis and inflammation-related proteins, including gasdermin D N-terminal (GSDMD-N), Caspase-1, NOD-like receptor family pyrin domain-containing 3 (NLRP3), interleukin 18 (IL-18), and interleukin 1beta (IL-1β). Moreover, HCG11 could modulate the JAK1 expression via targeting miR-224-3p. The inhibitory effect of HCG11 silencing on cell pyroptosis and inflammation was reversed by miR-224-3p knockdown. Furthermore, overexpression of miR-224-3p could repress the ox-LDL-induced cell pyroptosis and inflammation via regulating JAK1 expression. Knockdown of HCG11 alleviated cell pyroptosis and inflammation induced by ox-LDL via targeting the miR-224-3p/JAK1 axis, indicating that HCG11 could be the latent target of diagnosis or treatment for AS.

lncRNA HCG11 Promotes Colorectal Cancer Cell Malignant Behaviors via Sponging miR-26b-5p. J Immunol Res 2023; 2023:9011232.

Abstract
Colorectal cancer (CRC) is a type of gastrointestinal cancer with an increasing incidence. Long noncoding RNAs (lncRNAs) have raised great concern because of wide participation in human diseases, including cancers. However, whether lncRNA HLA complex group 11 (HCG11) played a functional role in CRC remained to be elucidated. Herein, we utilized qRT-PCR to analyze the expression of HCG11 and found that HCG11 was highly expressed in CRC cells. Besides, HCG11 knockdown suppressed cell proliferation, migration, and invasion but facilitated cell apoptosis. Furthermore, supported by bioinformatics analyses and mechanism assays, HCG11, mainly located in cell cytoplasm, was confirmed to competitively bind to miR-26b-5p to modulate the expression of the target messenger RNA (mRNA), namely, cAMP-regulated phosphoprotein 19 (ARPP19). ARPP19 was detected to be upregulated in CRC cells, and ARPP19 silence was verified to inhibit the malignant behaviors of CRC cells. Rescue experiments validated that miR-26b-5p inhibition or ARPP19 overexpression could countervail the inhibitory influences of HCG11 silence on CRC cell biological behaviors in vitro. To conclude, HCG11, upregulated in CRC cells, could promote cell proliferation, migration, and invasion and inhibit cell apoptosis via targeting miR-26b-5p/ARPP19 axis.

Abstract
Carotid artery stenosis (CAS) is one of the main risk factors of ischemic stroke (IS), which needs a screening and monitoring biomarker. The study focused on the clinical significance of long non-coding RNA (lncRNA) HCG11 in CAS patients aiming to identify a potential therapeutic target for CAS. Serum samples were collected from 70 CAS patients and 80 age- and gender-matched healthy people. HCG11 levels were measured via quantitative real-time PCR (qRT-PCR), and its significance in CAS identification and development prediction was also assessed. HCG11 was enriched in the serum of CAS patients, and serves as a possible biomarker for disease diagnosis with the area under the curve (AUC) of 0.930. Elevated expression of HCG11 was significantly correlated with hypertension, dyslipidemia, and degree of carotid stenosis. HCG11 was highly expressed in severe CAS cases compared to moderate ones, which was positively related to the disease severity. Cox regression analysis determined the close relationship of serum HCG11 with the occurrence of cerebral ischemia events. CAS patients with high HCG11 expression showed a high occurrence rate of cerebral ischemia events. The upregulation of HCG11 could serve as a potential diagnostic biomarker for CAS and is positively related to the disease severity. Serum HCG11 can independently predict the occurrence of following cerebral ischemia events.

Levels of plasma Quaking and cyclooxygenase-2 predict in-stent restenosis in patients with coronary artery disease after percutaneous coronary intervention. ZHONG NAN DA XUE XUE BAO. YI XUE BAN = JOURNAL OF CENTRAL SOUTH UNIVERSITY. MEDICAL SCIENCES 2022; 47:739-747.

Abstract
OBJECTIVES Percutaneous coronary intervention (PCI) is one of the important methods for the treatment of coronary artery disease (CAD). In-sent restenosis (ISR) after PCI for patients suffered from CAD is considered to be an essential factor affecting long-term outcomes and prognosis of this disease. This study aims to investigate the correlation between plasma Quaking (QKI) and cyclooxygenase-2 (COX-2) levels and ISR in patients with CAD. METHODS A total of 218 consecutive CAD patients who underwent coronary angiography and coronary arterial stenting from September 2019 to September 2020 in the Department of Cardiology of Xiangya Hospital of Central South University were enrolled in this study, and 35 matched individuals from the physical examination center were served as a control group. After admission, clinical data of these 2 groups were collected. Plasma QKI and COX-2 levels were measured by enzyme linked immunosorbent assay (ELISA). Follow-up angiography was performed 12 months after PCI. CAD patients were divided into a NISR group (n=160) and an ISR group (n=58) according to the occurrence of ISR based on the coronary angiography. The clinical data, coronary angiography, and stent features between the NISR group and the ISR group were compared, and multivariate logistic regression was used to explore the factors influencing ISR. The occurrence of major adverse cardiovascular events (MACE) 1 year after operation was recorded. Fifty-eight patients with ISR were divided into an MACE group (n=24) and a non-MACE group (n=34), classified according to the occurrence of MACE, and the plasma levels of QKI and COX-2 were compared between the 2 groups. Receiver operating characteristic (ROC) curves were utilized to analyze the diagnostic value of plamsa levels of QKI and COX-2 for ISR and MACE occurrences in patients after PCI. RESULTS Compared with control group, plasma levels of QKI and COX-2 in the CAD group decreased significantly (all P<0.001). Compared with the NISR group, the plasma levels of QKI and COX-2 also decreased obviously in the ISR group (all P<0.001), while the levels of high sensitivity C-reactive protein (hs-CRP) and glycosylated hemoglobin (HbAlc) significantly increased (all P<0.001). The level of COX-2 was negatively correlated with hs-CRP (r=-0.385, P=0.003). Multivariate logistic regression analysis showed that high level of plasma QKI and COX-2 were protective factors for in-stent restenosis after PCI, while hs-CRP was a risk factor. ROC curve analysis showed that the sensitivity and specificity of plasma QKI for evaluating the predictive value of ISR were 77.5% and 66.5%, respectively, and the sensitivity and specificity of plasma COX-2 for evaluating the predictive value of ISR were 80.0% and 70.7%, respectively. The sensitivity and specificity of plasma QKI combined with COX-2 for evaluating the predictive value of ISR were 81.3% and 74.1%, respectively. The sensitivity and specificity of plasma QKI for evaluating the prognosis of ISR were 75.0% and 64.7%, respectively. The sensitivity and specificity of plasma COX-2 for evaluating the prognosis of ISR were 75.0% and 70.6%, respectively. The sensitivity and specificity of plasma QKI combined with COX-2 for prognostic evaluation of ISR were 81.7% and 79.4%, respectively. The sensitivity and specificity of plasma COX-2 combined with QKI for evaluating ISR and MACE occurrences in patients after PCI were better than those of COX-2 or QKI alone (P<0.001). CONCLUSIONS High level of plasma QKI and COX-2 might be a protective factor for ISR, which can also predict ISR patient's prognosis.

Abstract
Background Diabetes has emerged as one of the most serious and common chronic diseases of our times, causing life-threatening, disabling and costly complications, and reducing life expectancy. Studies have shown that cardiovascular morbidity is 1–3 times higher in diabetic patients than in normal people. There are many clinical and experimental data that prove that most of the complications of diabetes are related to atherosclerosis, which suggests that chronic hyperglycemia may induce an imbalance in the proliferation of vascular endothelial cells. Purpose This study aims to explore the relationship between QKI-7 and vascular endothelial cell dysfunction and lay a foundation for further clarifying the molecular mechanism of endothelial cell damage in the process of diabetes with atherosclerosis. Methods We chose blood samples and pluripotent stem cells and vascular endothelial cells of hospitalized patients with diabetes and diabetes atherosclerosis as research subjects. The expression levels of endothelial cell proliferation and genes related to endothelial cell proliferation were analyzed by RT-qPCR and Western blot, to study the influence of QKi-7 on the physiological state of endothelial cells. Through gene knockdown experiment, the effects of QKi-7 knockdown on functional genes and physiological functions of endothelial cells were analyzed. Finally, RNA immunoprecipitation was used to test the mutual effect among QKI-7 and the transcription level of functional genes, and the mRNA attenuation experiment proved that QKI-7 participated in the degradation process of functional genes. Results The findings of the RT-qPCR and Western blot tests revealed that QKI-7 was highly expressed in blood samples of diabetic patients and atherosclerosis as well as in endothelial cells induced by human pluripotent stem cells and human vascular endothelial cells after high-glucose treatment. Overexpression and high glucose of QKI-7 resulted in inhibiting expressed function genes CD144, NLGN1, and TSG6 and upregulation of inflammatory factors TNF-α, IL-1β, and IFN-γ, leading to excessive proliferation of endothelial cells. After QKI-7 gene knockdown, the expression levels of CD144, NLGN1, and TSG6, inflammatory factors TNF-α, IL-1β, and IFN-γ, and the cell proliferation rate all returned to normal levels. RNA immunoprecipitation showed that QKi-7 interacted with CD144, NLGN1, and TSG6 mRNAs and was involved in the transcriptional degradation of functional genes through their interactions. Conclusion This research initially revealed the relevant molecular mechanism of QKI-7 leading to the excessive proliferation of endothelial cells in diabetic and atherosclerotic patients. In view of the role of QKI-7 in diabetic vascular complications, we provided a potential target for clinical diabetes treatment strategies in the future.

Abstract
Objective Acute coronary syndrome (ACS) is the most dangerous and deadly form of coronary heart disease. Herein, we aimed to explore ACS-specific circulating lncRNAs and their regulatory mechanisms. Methods This study collected serum samples from ACS patients and healthy controls for microarray analysis. Dysregulated circulating lncRNAs and mRNAs were determined with |log2fold − change| > 1 and p < 0.05. lncRNA-mRNA coexpression analysis was carried out. ENST00000538705.1 and ALOX15 expression was further verified in serum specimens. In human coronary artery endothelial cells (HCAECs), ENST00000538705.1 and ALOX15 were knocked out through transfecting specific siRNAs. Thereafter, proliferation and migration were investigated with CCK-8 and wound-healing assays. Myocardial infarction rat models were established and administrated with siRNAs against ENST00000538705.1 or ALOX15. Myocardial damage was investigated with H&E staining, and serum TC, LDL, and HDL levels were measured. Results Microarray analysis identified 353 dysregulated circulating lncRNAs and 441 dysregulated circulating mRNAs in ACS. Coexpression analysis indicated the interaction between ENST00000538705.1 and ALOX15. RT-qPCR confirmed the remarkable upregulation of circulating ENST00000538705.1 and ALOX15 in ACS patients. In HCAECs, ENST00000538705.1 knockdown lowered the expression of ALOX15 but ALOX15 did not alter the expression of ENST00000538705.1. Silencing ENST00000538705.1 or ALOX15 weakened the proliferation and migration of HCAECs. Additionally, knockdown of ENST00000538705.1 or ALOX15 relieved myocardial damage, decreased serum TC and LDL levels, and elevated HDL levels in myocardial infarction rats. Conclusion Collectively, our findings demonstrate that circulating ENST00000538705.1 facilitates ACS progression through modulating ALOX15, which provide potential targets for ACS treatment.

Abstract
Acute coronary syndrome (ACS) is a term used to describe major cardiovascular diseases, and treatment of in-stent restenosis in patients with ACS remains a major clinical challenge. Further investigation into molecular markers of ACS may aid early diagnosis, and the treatment of ACS and post-treatment recurrence. In the present study, total RNA was extracted from the peripheral blood samples of 3 patients with ACS, 3 patients with percutaneous coronary intervention (PCI)_non-restenosis, 3 patients with PCI_restenosis and 3 healthy controls. Subsequently, RNA library construction and high-throughput sequencing were performed. DESeq2 package in R was used to screen genes that were differentially expressed between the different samples. Moreover, the intersection of the differentially expressed mRNAs (DEmRNAs) and differentially expressed long noncoding RNAs (DElncRNAs) obtained. GeneCodis4.0 was used to perform function enrichment for DEmRNAs, and lncRNA-mRNA co-expression network was constructed. The GSE60993 dataset was utilized for diagnostic analysis, and the aforementioned investigations were verified using in vitro studies. Results of the present study revealed a large number of DEmRNAs and DElncRNAs in the different groups. We selected genes in the top 10 of differential expression and also involved in the co-expression of lncRNA-mRNA for diagnostic analysis in the GSE60993 dataset. The area under curve (AUC) of PDZK1IP1 (0.747), PROK2 (0.769) and LAMP3 (0.725) were all >0.7. These results indicated that the identified mRNAs and lncRNAs may act as potential clinical biomarkers, and more specifically, PDZK1IP1, PROK2 and LAMP3 may act as potential biomarkers for the diagnosis of ACS.

Abstract
Transcription factor-7-like-2 (TCF7L2), a vital member of the T-cell factor/lymphoid enhancer factor (TCF/LEF) family, plays an important role in normal human physiological and pathological processes. TCF7L2 exhibits multiple anti-atherosclerotic effects through the activation of specific molecular mechanisms, including regulation of metabolic homeostasis, macrophage polarization, and neointimal hyperplasia. A single-nucleotide substitution of TCF7L2, rs7903146, is a genetic high-risk factor for type 2 diabetes and indicates susceptibility to cardiovascular disease as a link between metabolic disorders and atherosclerosis. In this review, we summarize the anti-atherosclerosis effect and novel mechanisms underlying the function of TCF7L2 to elucidate its potential as an anti-atherosclerosis biomarker and provide a novel therapeutic target for cardiovascular diseases.

Abstract
Numerous differentially expressed circular RNAs (circRNAs) have been identified; however, their roles have not been fully elucidated. Since dysregulated circRNAs may have clinical applications, it is vital to study their expression characteristics, function, and mechanism in prostate cancer cells. The role, regulatory mechanism, and expression of hsa_circ_0075542 were analyzed using quantitative reverse transcription polymerase chain reaction. The results indicated that the expression of hsa_circ_0075542 was downregulated in prostate tumor tissues. The functions of prostate cancer cell lines LNCaP and PC3 cells were assessed using cell counting kit-8 and transwell assays and flow cytometry analysis. The results of the functional experiments showed that overexpression of hsa_circ_0075542 suppressed cell proliferation, reduced migration and invasiveness capabilities, and promoted apoptosis. Moreover, hsa_circ_0075542 targeted the microRNA-1197 (miR-1197) homeobox C11 (HOXC11) axis by sponging miR-1197. Overexpression of miR-1197 played a tumor-promoting role. Overexpression of hsa_circ_0075542 alleviated the tumor-promoting effect of miR-1197 overexpression In conclusion, hsa_circ_0075542 suppressed malignant characteristics and promoted apoptosis in LNCaP and PC3 cells by acting as a competing endogenous RNA of miR-1197. The hsa_circ_0075542/miR-1197 axis might play a role via HOXC11.

MicroRNA-26b-5p suppresses the proliferation of tongue squamous cell carcinoma via targeting proline rich 11 (PRR11). Bioengineered 2021; 12:5830-5838.

Abstract
MicroRNAs (miRNAs) have been proved to be involved in many biological processes during tumorigenesis and progression, including cell proliferation and cell cycle progression. However, the potential role of miR-26b-5p in tongue squamous cell carcinoma (TSCC) remains unclear. In the present study, we demonstrated that miR-26b-5p was decreased in TSCC tissues in both TCGA-TSCC subset and eight paired samples from TSCC patients, while Proline Rich 11 (PRR11) was obviously increased. Transfection of miR-26b-5p mimics inhibited CALL7 cell proliferation by arresting the cells at the S/G2 transition. Meanwhile, miR-26b-5p inhibitor had the opposite biological functions. The results of luciferase activity and RNA-pulldown assays indicated that miR-26b-5p directly targeted the PRR11 3' -untranslated region in CAL27 cells. Furthermore, the effects of miR-26b-5p on cell cycle regulation were reversed after treatment with siRNA against PRR11. In summary, our findings indicate that miR-26b-5p induce cell cycle arrest in TSCC by targeting PRR11. Hence, targeting miR-26b-5p could be a promising therapeutic strategy for the treatment of TSCC.

Zhang Y, Wei J, Zhang L, Jiang G, Wang B, Jiang L. Extracellular vesicle-derived miR-26b-5p is up-regulated in the serum of patients with diabetic retinopathy. Comb Chem High Throughput Screen 2021; 25:877-882. [PMID: 33593252 DOI: 10.2174/1386207324666210216092917] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2020] [Revised: 01/27/2021] [Accepted: 02/01/2021] [Indexed: 11/22/2022]
Abstract
BACKGROUND Diabetic retinopathy (DR) is a severe complication of diabetes; however, the pathogenesis of DR has not been completely clarified, which is mostly dependent on the molecular pathology. To investigate key serum-derived miRNAs associated with DR. METHODS miRNA expression profile arrays of human umbilical vein endothelial cells (HUVECs) treated with glucose were downloaded from the Gene Expression Omnibus (GEO) database (GSE74296). Weighted gene co-expression network analysis (WGCNA) was performed to obtain hub miRNAs, which were verified in HUVECs treated with 40 mM and 5 mM glucose, respectively. Meanwhile, serum samples of patients with DR and healthy controls were collected, and EVs were extracted from the patients' serum by ultracentrifugation. Hub miRNAs associated with endothelial dysfunction were verified in healthy individuals before and after treatment of patients with DR, by qRT-PCR. RESULTS These miRNAs were categorized into six modules, among which miR-26b-5p had a strong association with other modules. This miRNA was also one of the hyperglycemia-induced miRNAs related to endothelial dysfunction. miR-26b-5p was upregulated in HUVECs treated with 40 mM glucose and in the serum of patients with DR before and after treatment Furthermore, miR-26b-5p was slightly up-regulated in serum-derived EVs but not in serum without EVs in DM patients. CONCLUSION Our results suggest that EVs derived from miR-26b-5p are up-regulated in the serum of patients with DR.
