Abstract
PURPOSE To find a useful disease marker for early diagnosis of gastric cancer, we tried to explore the expression of serum miR-181, miR-652, and carbohydrate antigen 72-4 (CA72-4). PATIENTS AND METHODS According to clinical pathologic stages, 112 patients with gastric cancer were divided into early gastric cancer group (n = 60) and advanced gastric cancer group (n = 52), stage I-II (n = 65), and stage III-IV (n = 47). Another 50 cases of gastric benign lesions and 40 healthy controls were also selected. Real-time quantitative PCR together with chemiluminescence were applied to detect expression levels. ROC curve was applied to judge their diagnostic efficiency. Pearson's correlation analysis was put into use to investigate the relevance of three indicators. RESULTS Compared with benign lesions group and control group, significantly higher expression levels were found in patients of gastric cancer (all p < 0.001). Similarly, compared with early gastric cancer group, significantly higher expression levels were found in advanced gastric cancer group (all p < 0.001). The same result was also found in stage III-IV (all p < 0.001). The best cutoff values were 0.93, 2.38, and 16.94 U/ml, respectively. The area under the curve (0.917, 95%CI: 0.856-0.975) of the three combined diagnosis of early gastric cancer was the largest, and its sensitivity and specificity were 92.5% and 86.8%. And miR-181 and miR-652 were positively correlated with CA72-4 (r = 0.772, p < 0.001, r = 0.853, p < 0.001). CONCLUSION Serum miR-181, miR-652, and CA72-4 are closely linked to the occurrence and development of gastric cancer. Combination of three indicators has diagnostic value for early gastric cancer.

Abstract
Background Hemorrhoids are a frequently-occurring disease of the anorectal system that is often accompanied by vascular hyperplasia and edema. A METTL14-mediated RNA N-6 methyladenosine (m6A) modification can improve mRNA stability and increase its transcriptional and translational activities, closely related to the occurrence of many diseases. Methods Western blot, qPCR, and immunofluorescence staining were used to detect the levels of gene and protein expression. Haematoxylin and eosin staining was used for histopathological examination. RNA immunoprecipitation-PCR and RNA dot blotting were used to detect mRNA m6A modification. Results Obvious signs of angiogenesis (CD31+/vWF+) were identified in the hemorrhoids. High levels of METTL14 expression on vascular endothelial cells (CD31+) suggested that angiogenesis was accompanied by differential modification of m6A RNA. It was subsequently found that the level of miR-4729 expression was significantly decreased in hemorrhoid tissues. The luciferase reporter enzyme assay results suggested that miR-4729 silenced its expression by targeting the 3'UTR of METTL14 mRNA. MiR-4729 overexpression in human umbilical vein endothelial cells (HUVECs) inhibited the proliferation and migration of HUVECs in vitro and vascular structure formation in the outer matrix. MiR-4729 overexpression significantly inhibited endogenous METTL14 expression in HUVECs and reduced the entire m6A RNA modification, especially the level of m6A methylation at the specific site of the 3' UTR of TIE1 mRNA. Moreover, miR-4729 overexpression significantly inhibited the molecular loop of the TIE1/VEGFA signaling pathway in HUVECs. Conclusions Our findings confirmed that the down-regulation of miR-4729 in hemorrhoid vascular endothelial cells was one of the main reasons for vascular proliferation. The overexpression of miR-4729 in vascular endothelial cells decreased the global mRNA methylation and TIE1 mRNA 3'UTR-specific site methylation by silencing METTL14 expression, reducing TIE1 mRNA stability, down-regulating the TIE1/VEGFA signal molecular loop expression, and weakening angiogenesis ability.

Abstract
BACKGROUND Haemorrhoids occur commonly and frequently in the human digestive system. There are diverse causes of haemorrhoids and their in-depth pathogenesis is still currently unclear. METHODS In this study, we explored haemorrhoids from an epigenetics perspective by employing RNA-Seq for comprehensive and in-depth analysis of the differences in microRNA (miRNA) transcripts between haemorrhoidal tissue and normal tissue in 48 patients with Grade II and above haemorrhoids. RESULTS The results showed that 9 miRNAs were significantly upregulated (ratio > 3.5 and P-value < 0.01) and 16 miRNAs were significantly downregulated (ratio > 0.6 and P-value < 0.01) in haemorrhoid tissue. Subsequently, target gene prediction results showed that there were 184 potential target genes of significantly upregulated miRNAs (common to both TargetScan7.1 and MirdbV5 databases) and there were 372 potential target genes of significantly downregulated miRNAs. Gene ontology analysis results showed that the target genes of differentially expressed miRNAs in haemorrhoids are involved in regulating "cell composition" and "protein binding". Lastly, KEGG search found that the differentially expressed miRNAs that are associated with the occurrence of haemorrhoids mainly regulate the activity of endocytosis and the synaptic vesicle cycle. CONCLUSIONS In summary, the results of high-throughput RNA-Seq screening suggested that the occurrence of haemorrhoids may be intimately associated with aberrant miRNA transcription, resulting in aberrant target gene expression and an imbalance in certain signal transduction pathways.

Abstract
Hemorrhoid is a common and recurrent proctological disease, which is often accompanied by angiogenesis and edema. MicroRNAs in the DLK1-DIO3 imprinted clusters are involved in the development and pathogenesis of mammalian hemorrhoids. Results of the present study indicated multiple, differential expression of DLK1-DIO3 imprinted cluster microRNA between hemorrhoid and normal tissues, where miR-412-5p expression in hemorrhoid tissue was significantly decreased. Fluorescein reporter assays showed that miR-412-5p silenced Xpo1 mRNA expression by targeting its 3'-UTR. Overexpression of miR-412-5p in human umbilical vein endothelial cells (HUVECs) indicated that proliferation, migration and formation of vascular structures in HUVECs were inhibited in vitro. In addition, overexpression of miR-412-5p significantly inhibited Xpo1 expression and promoted upregulation of the p53 protein and its retention in the nucleus. Simultaneously, expression of p66SHC and p16 proteins was activated. In summary, downregulation of endogenous miR-412-5p expression in hemorrhoid vascular endothelial cells leads to high expression of the target gene Xpo1 and translocation of the p53 protein out of the nucleus, rendering it unable to activate p66SHC and p16. This ultimately weakens regulation of the vascular endothelial cell cycle, thereby accelerating the division of hemorrhoid vascular endothelial cells, leading to angiogenesis.
