Background: miR-20b has been shown to be aberrantly expressed in several tumor types. However, the clinical significance of miR-20b in the prognosis of patients with gastric cancer (GC) is poorly understood, and the exact role of miR-20b in GC remains unclear.
Materials And Methods: The expression of miR-20b was detected in 102 patients with GC by a SYBR Green assay and was compared with the expression in matched adjacent normal tissue specimens. The aim of the present study was to investigate the association of the expression of miR-20b with the clinicopathological characteristics and the overall survival of patients with GC as analyzed by Kaplan-Meier analysis and Cox proportional hazards regression models.
Results: Our results showed that miR-20b expression was upregulated in GC tissue compared with normal mucosa (P=0.00). Furthermore, miR-20b expression was positively correlated with advanced lymph node metastasis (P=0.041), tumor node metastasis stage (P=0.000), and deeper and distant metastasis (P=0.031). The overall survival rate of patients with GC was significantly lower in those whose tumors expressed high levels of miR-20b mRNA compared with those whose tumors expressed low levels of miR-20b mRNA (P=0.019).
Conclusion: miR-20b may serve as a potential molecular marker for the prognosis of GC.

MicroRNAs (miRNAs) play a significant role in tumor progression, and regulating miRNA expression with small molecules may offer a new approach to cancer therapy. Among them, miRNA-20b has been found to be dysregulated in several cancers, including nonsmall cell lung cancer (NSCLC). Herein, an in silico high-throughput computer screen was conducted to identify small molecules that downregulate miR-20b using the three-dimensional structure of the Dicer binding site on pre-miR-20b.

Introduction: This study aimed to investigate alterations in intravitreal microRNA and vascular endothelial growth factor (VEGF) levels in patients with proliferative diabetic retinopathy (PDR) as these factors are implicated in PDR pathogenesis.
Methods: Fifty-two participants, including 26 patients with PDR and 26 controls without diabetes, were included in this study. VEGF levels were assessed using ELISA, and seven microRNAs (miRNAs) (miR-19a, miR-20b, miR-27a, miR-124, miR-126-3p, miR-146a, and miR-200b) were analyzed using quantitative real-time PCR.

Purpose: To explore the expressions and functions of lncRNAs in the pathogenesis of pathologic myopia complicated with cataract (PMC).
Methods: The anterior capsular tissues were collected from patients with age-related cataract (ARC) and PMC. One group of the samples was used to detected by whole-transcriptome sequencing (LC-Bio, Hangzhou, China) and investigated by GO and KEGG enrichment analysis.
