Abstract

Nasopharyngeal carcinoma (NPC), a malignant tumor originating from the epithelium and glands. MicroRNAs (miRNAs) play an essential role in the tumorigenesis and metastasis of NPC. They are effective biomarkers in the detection of malignant progression of NPC. In this study, we analyzed the expression profiles of miRNAs in NPC patients with Gene Expression Omnibus (GEO) database. ceRNA networks of NPC were constructed and target miRNAs were screened. MTT, colony formation and Transwell experiments were used to explore the effects of miR-205-5p on the proliferation, migration and invasion ability of NPC cells. Bioinformatics analysis combined with Double luciferase experiment verified the binding relationship between miR-205-5p and CALM1. We identified 34 long non-coding RNAs (lncRNAs), 22 miRNAs, and 145 messenger RNAs (mRNAs) and constructed a competing endogenous RNAs (ceRNA) network to explain the relationship between RNA expression profiles and NPC progression. Of which, we found that 5 miRNAs (hsa-let-7d-5p, hsa-let-7e-5p, hsa-let-7f-5p, hsa-miR-143-3p and hsa-miR-205-5p) are related to clinical features. We further found that miR-205-5p was highly expressed in NPC cell lines. In addition, MTT, colony formation and Transwell assays showed that miR-205-5p promoted the proliferation, migration and invasion of NPC cells. Double luciferase detection showed that miR-205-5p could target combined with CALM1. In addition, we found that miR-205-5p could promote the proliferation, migration and invasion of NPC cells by inhibited the expression of CALM1. Overall, the present study demonstrated that as a carcinogenic factor, miR-205-5p can affect the malignant progression of NPC by mediating CALM1.

miR-205-5p通过调节CALM1促进鼻咽癌细胞的增殖、迁移和侵袭
鼻咽癌,一种起源于上皮和腺体的恶性肿瘤。MicroRNAs (miRNAs)在鼻咽癌的发生和转移中起着重要的作用。它们是检测鼻咽癌恶性进展的有效生物标志物。在这项研究中,我们利用基因表达Omnibus (GEO)数据库分析了鼻咽癌患者中miRNAs的表达谱。构建NPC的ceRNA网络,筛选目标mirna。通过MTT、集落形成和Transwell实验探讨miR-205-5p对鼻咽癌细胞增殖、迁移和侵袭能力的影响。生物信息学分析结合双荧光素酶实验验证了miR-205-5p与CALM1的结合关系。我们鉴定了34种长链非编码RNA (lncrna)、22种mirna和145种信使RNA (mrna),并构建了一个竞争性内源性RNA (ceRNA)网络来解释RNA表达谱与鼻咽癌进展之间的关系。其中,我们发现5种mirna (hsa-let-7d-5p、hsa-let-7e-5p、hsa-let-7f-5p、hsa-miR-143-3p和hsa-miR-205-5p)与临床特征相关。我们进一步发现miR-205-5p在鼻咽癌细胞系中高表达。此外,MTT、集落形成和Transwell实验表明,miR-205-5p促进鼻咽癌细胞的增殖、迁移和侵袭。双荧光素酶检测显示miR-205-5p可靶向联合CALM1。此外,我们发现miR-205-5p可以通过抑制CALM1的表达促进鼻咽癌细胞的增殖、迁移和侵袭。总之,本研究表明miR-205-5p作为一种致癌因子,可以通过介导CALM1影响NPC的恶性进展。

期刊介绍: Immunology covers a broad spectrum of investigations at the genes, molecular, cellular, organ and system levels to reveal defense mechanisms against pathogens as well as protection against tumors and autoimmune diseases. The great advances in immunology in recent years make this field one of the most dynamic and rapidly growing in medical sciences. Critical ReviewsTM in Immunology (CRI) seeks to present a balanced overview of contemporary adaptive and innate immune responses related to autoimmunity, tumor, microbe, transplantation, neuroimmunology, immune regulation and immunotherapy from basic to translational aspects in health and disease. The articles that appear in CRI are mostly obtained by invitations to active investigators. But the journal will also consider proposals from the scientific community. Interested investigators should send their inquiries to the editor before submitting a manuscript.
