PURPOSE MicroRNA (miRNA) expression profiles improve classification, diagnosis, and prognostic information of malignancies, including lung cancer. This study uncovered unique growth-suppressive miRNAs in lung cancer. EXPERIMENTAL DESIGN miRNA arrays were done on normal lung tissues and adenocarcinomas from wild-type and proteasome degradation-resistant cyclin E transgenic mice to reveal repre...

BACKGROUND MicroRNAs (miRNAs) have been shown to play a critical role in the development and progression of nasopharyngeal carcinoma (NPC). Although accumulating studies have been performed on the molecular mechanisms of NPC, the miRNA regulatory networks in cancer progression remain largely unknown. Laser capture microdissection (LCM) and deep sequencing are powerful tools that can help us to ...

ObjectiveTo investigate microRNA (miRNA) expression profiles in the seminal plasma of nonobstructive azoospermia (NOA) patients with different histopathologic patterns and evaluate potential noninvasive diagnostic biomarkers NOA.DesignSequencing validation using quantitative reverse transcription polymerase chain reaction (qRT-PCR).SettingReproductive center research institute.Patient(s)Thirtee...

Endometrial carcinoma (EC) is a common malignancy of the female genital tract with a poor prognosis. It has been reported that miR-34c is significantly reduced in EC, but research concerning its function in EC is rare. In the present study, the expression of miR-34c was upregulated in the EC cell line, HEC-1-B, by transfecting the cells with hsa-miR-34c-5p mimics. Then, after determining the tr...

To characterize microRNAs (miRNAs) involved in testicular toxicity in cynomolgus monkeys, miRNA profiles were investigated using next-generation sequencing (NGS), microarray and reverse transcription-quantitative real-time-PCR (RT-qPCR) methods. First, to identify organ-specific miRNAs, we compared the expression levels of miRNAs in the testes to those in representative organs (liver, heart, ki...

Previous studies have demonstrated a close relationship between abnormal regulation of microRNA (miRNA) and various types of diseases, including epilepsy and other neurological disorders of memory. However, the role of miRNA in the memory impairment observed in epilepsy remains unknown. In this study, a model of temporal lobe epilepsy (TLE) was induced via pentylenetetrazol (PTZ) kindling in Sp...

Sirtuin 6 (SIRT6) is a member of the nicotinamide adenine dinucleotide positivity-dependent class III deacetylase sirtuin family. The present study aimed to explore the expression and function of SIRT6 in colon cancer. Furthermore, the partial mechanism underlying the dysregulation of SIRT6 was investigated. The results of immunohistochemistry demonstrated that SIRT6 was markedly downregulated ...

HIV-associated neurocognitive disorders (HAND) represent a spectrum neurological syndrome that affects up to 25% of patients with HIV/AIDS. Multiple pathogenic mechanisms contribute to the development of HAND symptoms including chronic neuroinflammation and neurodegeneration. Among the factors linked to development of HAND is altered expression of host cell microRNAs (miRNAs) in brain. Here, we...

To comparatively analyze the human microRNA (miRNA) profiles between spontaneous decidualized menstrual endometrium and early pregnancy decidua by an in-depth sequencing of miRNAs. The specific miRNAs expressed at conception might be involved in pregnancy establishment and expression of let-7f-5p and let-7g-5p was experimentally up-regulated or inhibited to assess the effect on the expression o...
