Porcine hemagglutinating encephalomyelitis virus (PHEV) invades the central nervous system (CNS) and causes neurodegenerative disease in suckling piglets, but the understanding of its neuropathogenicity for neurological dysfunction remains limited. Here, we report that miR-142-5p is localized to neurons and negatively regulates neuronal morphogenesis in porcine hemagglutinating encephalomyelitis (PHE). This phenotype was mediated by miR-142-5p inhibition of an mRNA encoding unc-51-like-kinase1 (Ulk1), which controls axon outgrowth and dendrite formation...

Cancer immunotherapy has many great achievements in recent years. One of the most promising cancer immunotherapies is PD-1/PD-L1 pathway blockade. miRNAs (MicroRNAs) belongs to small noncoding RNA and can regulate gene expression by binding to the 3'UTR. Many miRNAs can inhibit cancer growth by regulating the PD-L1 expression in cancer cells. Herein, we firstly found that PD-L1 could be the target of miR-142-5p by using bioinformatics methods, then we conduct luciferase activity assay, RT-PCR and western blot experiments to demonstrate that miR-142-5p can regulate PD-L1 expression by binding to its 3'UTR...

The dysfunction of endothelial cells (ECs) plays crucial roles in vascular remodeling during hypertension. Researches suggested that ECs are regulated by the circulating platelets in vivo, which may participate in abnormal EC apoptosis in hypertension. However the molecular mechanism in this process is still unclear. Here we focused on the microRNAs (miRs) in platelets, and detected the potential role and delivery mechanism of platelet-derived miRs in ECs. Using microarray, the differentially expressed profile of miRs between platelets and ECs was detected...

T-cell development is a spatially and temporally regulated process, orchestrated by well-defined contributions of transcription factors and cytokines. Here, we identify the non-coding RNA miR-142 as an additional regulatory layer within murine thymocyte development and proliferation. MiR-142 deficiency impairs the expression of cell cycle-promoting genes in mature mouse thymocytes and early progenitors, accompanied with increased levels of Cyclin-dependent kinase inhibitor 1B (Cdkn1b, also known as p27(Kip1) )...

Melanoma remains the leading cause of skin cancer-related deaths. Surgical resection and adjuvant therapies can result in disease-free intervals for stage III and stage IV disease; however, recurrence is common. Understanding microRNA (miR) dynamics following surgical resection of melanomas is critical to accurately interpret miR changes suggestive of melanoma recurrence. Plasma of 6 patients with stage III (n = 2) and stage IV (n = 4) melanoma was evaluated using the NanoString platform to determine pre- and postsurgical miR expression profiles, enabling analysis of more than 800 miRs simultaneously in 12 samples...

BACKGROUND: The discovery of circulating microRNAs (miRNAs), as potential noninvasive diagnostic biomarkers, has opened new avenues of research for identifying patients with chronic failure in renal transplantation. The present study aimed to investigate the expression levels of four immune-related miRNAs (miR-21, miR-31, miR-142-3p and miR-155) in plasma samples of renal recipients. METHODS: The plasma expression levels of the miRNAs were evaluated by quantitative real-time PCR (qPCR) in 53 renal recipients with long-term stable allograft function, SGF (N = 27), and with biopsy-proven interstitial fibrosis and tubular atrophy (IFTA) (N = 26) and also healthy controls (N = 15)...

miR-142-3p was reported to be downregulated in acute myelogenous leukemia (AML) and acted as a novel diagnostic marker. However, the regulatory effect of miR-142-3p on drug resistance of AML cells and its underlying mechanism have not been elucidated. Here, we found that miR-142-3p was significantly downregulated and high mobility group box 1 (HMGB1) was dramatically upregulated in AML samples and cells, as well as drug-resistant AML cells. P-gp level and autophagy were markedly enhanced in HL-60/ADR and HL-60/ATRA cells...

BACKGROUND AND AIMS: Although circulating microRNA (miRNAs) have emerged as biomarkers predicting mortality in acute coronary syndrome (ACS), more data are needed to understand these mechanisms. Mapping miRNAs to high-risk traits may identify miRNAs involved in pathways conferring risk for poor outcome in ACS. We aim to investigate the relationship between circulating miRNAs and high-risk traits in non-ST-segment elevation acute coronary syndrome (NSTE-ACS). METHODS: Whole-genome miRNA sequencing was performed on RNA extracted from whole blood of 199 patients with NSTE-ACS...

BACKGROUND: Non-small-cell lung cancer (NSCLC) is a deadly cancer with high mortality rate. Drug resistance represents a main obstacle in NSCLC treatment. High mobility group box-1 (HMGB1) protein promotes drug resistance in NSCLC cells by activating protective autophagy. METHODS: In the current study, we investigated the regulatory role of microRNA-142-3p (miR-142-3p) in HMGB1-mediated autophagy of NSCLC cells and its impact on drug resistance of NSCLC in vitro and in vivo...

Myeloid cells play a key role in tumor progression and metastasis by providing nourishment and immune protection, as well as facilitating cancer invasion and seeding to distal sites. Although advances have been made in understanding the biology of these tumor-educated myeloid cells (TEMCs), their intrinsic plasticity challenges our further understanding of their biology. Indeed, in vitro experiments only mimic the in vivo setting, and current gene-knockout technologies do not allow the simultaneous, temporally controlled, and cell-specific silencing of multiple genes or pathways...

P73 antisense RNA 1T (non-protein coding), also known as TP73-AS1 or PDAM, is a long non-coding RNA which may regulate apoptosis via regulation of p53-dependent anti-apoptotic genes. An abnormal change of TP73-AS1 expression was noticed in cancers. The effects of TP73-AS1 in brain glioma growth and the underlying mechanism remain unclear so far. In the present study, TP73-AS1 was specifically upregulated in brain glioma tissues and cell lines and was associated with poorer prognosis in patients with glioma...

BACKGROUND: Expression of host microRNAs (miRNAs) changes markedly during influenza A virus (IAV) infection of natural and adaptive hosts, but their role in genetically determined host susceptibility to IAV infection has not been explored. We, therefore, compared pulmonary miRNA expression during IAV infection in two inbred mouse strains with differential susceptibility to IAV infection. RESULTS: miRNA expression profiles were determined in lungs of the more susceptible strain DBA/2J and the less susceptible strain C57BL/6J within 120 h post infection (hpi) with IAV (H1N1) PR8...

Recently, emerging evidence has demonstrated that metastasis-associated lung adenocarcinoma transcript 1 (MALAT1), a long non-coding RNAs (lncRNAs), contributes to the initiation and development of tumors, including osteosarcoma (OS). Multiple studies have suggested an oncogenic role of MALAT1 and high-mobility group protein B1 (HMGB1) in OS tumorigenesis and metastasis, but the effects and mechanisms are not unanimous. Here, we showed that MALAT1 and HMGB1 were significantly increased in human OS cell lines and knockdown of MALAT1 reduced HMGB1 expression...

Purpose: Dry age-related macular degeneration (AMD) is characterized by the accumulation of drusen under Bruch's membrane, and amyloid beta (Aβ) is speculated to be one of the key pathologic factors. While the detrimental effects of Aβ on retinas have been widely explored, Aβ-induced epigenetic regulatory changes have yet to be fully investigated. We therefore aimed to identify the microRNA (miRNA) expression profiles in an Aβ-induced mouse model of retinal degeneration. Methods: C57BL/6 mice were intravitreally injected with Aβ1-40 or PBS and the eye tissues were collected for hematoxylin and eosin (H&E) staining, apoptosis immunofluorescence staining, and miRNA profiling...
