Metformin, an anti-diabetic drug commonly used for type 2 diabetes therapy, is associated with anti-angiogenic effects in conditions beyond diabetes. miR-21 has been reported to be involved in the process of angiogenesis. However, the precise regulatory mechanisms by which the metformin-induced endothelial suppression and its effects on miR-21-dependent pathways are still unclear. Bioinformatic analysis and identification of miR-21 and its targets and their effects on metformin-induced antiangiogenic activity were assessed using luciferase assays, quantitative real-time PCR, western blots, scratch assays, CCK-8 assays and tubule formation assays...

Tuberculosis (TB) is one of the prevalent causes of death worldwide, with 95% of these deaths occurring in developing countries, like India. The causative agent, Mycobacterium tuberculosis (MTb) has the tenacious ability to circumvent the host's immune system for its own advantage. Macrophages are one of the phagocytic cells that are central to immunity against MTb. These are highly plastic cells dependent on the milieu and can showcase M1/M2 polarization. M1 macrophages are bactericidal in action, but M2 macrophages are anti-inflammatory in their immune response...

MicroRNAs (miRNAs) play an increasingly important role in cancer growth by coordinately suppressing genes that controlcell migration, proliferationand invasion. The above results can be achieved through the regulation of gene expression by miRNAs bysuppressing translation or the directsequence-specific degradation of the targetedmRNA. In the present study, we indicate that the expression of miR-216b could be effectively repressed both in human melanoma tissues through a comparison with primary melanoma and in human melanoma cell lines through a comparison with a normal human keratinocyte line...

The mosquito Aedes aegypti is a major vector of numerous viral diseases, because it requires a blood meal to facilitate egg development. The fat body, a counterpart of mammalian liver and adipose tissues, is the metabolic center, playing a key role in reproduction. Therefore, understanding of regulatory networks controlling its functions is critical, and the role of microRNAs (miRNAs) in the process is largely unknown. We aimed to explore miRNA expression and potential targets in the female fat body of Ae. aegypti, as well as their changes postblood meal (PBM)...

Endothelial dysfunction played an important role in the progression of diabetes mellitus (DM). miR-181c has been implicated in many diseases, including DM. However, the molecular mechanisms of miR-181c regulate this process remained poorly understood. Healthy ICR mice were divided into control group (n = 10) and db/db DM group (n = 10). The expression of miR-181c and FoxO1 were both investigated in diabetic db/db mice or high glucose-induced endothelial cells (MAECs and END-D). Here we found that down-regulation of miR-181c and the activation of FoxO1/iNOS were observed in mice and endothelial cells...

BACKGROUND The morbidity of erectile dysfunction (ED) has been found to be substantially increased in patients with chronic prostatitis (CP). Accumulating evidence shows that single-nucleotide polymorphism (SNP) located in pre-miRNA or mature microRNA may affect the processing of microRNA (miRNA) and alter the expression of the miRNA, as well as its target gene. In this study we investigated the association between rs2910164 G/C polymorphism and risk of ED in patients with CP, as well as the underlying molecular mechanism...

Understanding the fundamental nature of a molecular process or a biological pathway is often a catalyst for the development of new technologies in biology. Indeed, studies from late 1990s to early 2000s have uncovered multiple overlapping but functionally distinct RNA silencing pathways in plants, including the posttranscriptional microRNA and small interfering RNA pathways and the transcriptional RNA-directed DNA methylation pathway. These findings have in turn been exploited for developing artificial RNA silencing technologies such as hairpin RNA, artificial microRNA, intrinsic direct repeat, 3' UTR inverted repeat, artificial trans-acting siRNA, and virus-induced gene silencing technologies...

X-box binding protein 1 (XBP1), a vital basic leucine zipper transcription factor for the related gene transcription in endoplasmic reticulum (ER) stress, belongs to the CREB/ATF family. In mammals, XBP1S is the activated one of XBP1 isoform. In order to study the role of fish XBP1S, we cloned and identified the XBP1S (KU509247) from grass carp (Ctenopharyngodon idella) (named CiXBP1S) by homologous cloning and RACE technique. The full length of CiXBP1S is 1694 bp along with 124 bp of 5' UTR, 418 bp of 3' UTR and the longest open reading frame (1152 bp) encoding a polypeptide of 383 amino acids with a well conserved DNA binding domain (BRLZ domain)...

BACKGROUND/AIMS: Osteogenic differentiation of mesenchymal stem cells (MSCs) plays a crucial role in bone regeneration and bone reparation. This complex process is regulated precisely and firmly by specific factors. Recent studies have demonstrated that miR-125b regulates osteogenic differentiation, but little is known about the molecular mechanisms of this regulation. Furthermore, how miR-125b regulates the osteogenic differentiation of MSCs still needs elucidation. METHODS: In the present study, human bone marrow-derived mesenchymal stem cells (hBMSCs) were isolated and induced to osteoblasts with miR-125b inhibition or overexpression...

OBJECTIVE AND METHOD: We developed and evaluated five novel real-time RT-PCR assays targeting conserved regions in the 5'-untranslated region (5'-UTR), envelope (E'), non-structural protein 2A (NS2A), NS5, and 3'-UTR of the ZIKV genome. RESULTS: The ZIKV-5'-UTR assay exhibited the lowest in-vitro limit of detection (5-10 RNA copies/reaction and 3.0×10(-1) plaque-forming units/ml). Compared to the modified version of a widely adopted RT-PCR assay targeting the ZIKV-E gene, the ZIKV-5'-UTR assay showed better sensitivity in human clinical specimens, and representative mouse specimens, including many organs which are known to be involved in human ZIKV infection but difficult to obtain in clinical settings...

By analyzing the expression profile of microRNAs in head and neck squamous cell carcinomas (HNSCC), we found that the expression level of miR-124 was 4.59-fold lower in tumors than in normal tissues. To understand its functions, we generated a miR-124-expressing subline (JHU-22miR124) and a mock vector-transfected subline (JHU-22vec) by transfecting the mimic of miR-124 into JHU-22 cancer cells. Restored expression of miR-124 in JHU-22miR124 cells led to reduced cell proliferation, delayed colony formation, and decreased tumor growth, indicating a tumor-suppressive effect of miR-124...

Glioblastoma is the most common type of malignant primary brain tumor and has high recurrence and lethality rates. Glioblastoma stem cells (GSCs), a subpopulation of glioblastoma cells, may promote rapid tumor recurrence and therapy resistance. Because altered microRNA (miR) expression in GSCs may lead to glioblastoma progression, we assessed the effects of miR-29a expression on the oncogenic behavior of GSCs. MiR-29a expression was lower in GSCs than non-GSCs, and overexpression of miR-29a in GSCs inhibited cell proliferation, migration and invasion, but promoted apoptosis...
