MiRNA profiling of Macaca nemestrina plasma samples: before SIV infection and during acute infection

ABSTRACT: This study describes a circulating miRNA signature of acute retroviral infection, which may include candidate diagnostic or prognostic miRNAs for lentivirus-associated neurologic conditions. Plasma samples were taken from six macaques prior to infection and at ten days post-infection. Three macaques each went on to develop no or severe encephalitis. miRNA profiles were generated for each animal before and 10 days after SIV infection.

TaqMan Peripheral blood mononuclear cell miRNA profiles of HIV-1-infected elite suppressors, viremic patients, and uninfected control donors

Project description:This study used TaqMan low-density arrays to identify and quantitate circulating cellular miRNAs during HIV-1 elite suppression, active HIV-1 replication, and uninfected status. Blood samples were from six uninfected controls, six HIV-1 elite suppressors with undetectable viral load, and six viremic HIV-1-infected patients.

miRNA profiling of plasma samples: patients with unstable coronary artery disease and controls

Project description:This study describes a circulating miRNA signature of unstable angina (UA), which may be used as a novel biomarker for unstable coronary artery disease (CAD). The Taqman low-density miRNA array were used to identify distinct miRNA expression profiles in the plasma of patients with typical UA and angiographically documented CAD (UA group, n = 13) compared to individuals with non-cardiac chest pain (control group, n = 13). EDTA-plasma samples were obtained before the cardiac catheterization procedure.The study included 2 groups that were classified according to angiographic evidence and clinical evaluation of chest pain. Patients with chest pain or discomfort but with angiographic exclusion of coronary atherosclerosis were enrolled in the control group (n = 13). Chest discomfort referred to the following complaints: chest pain, pressure, tightness, or heaviness; pain that radiated to the neck, jaw, shoulders, back, or one or both arms; and persistent shortness of breath. Patients with typical unstable angina (UA) and angiographically documented CAD were enrolled in the UA group (n = 13).

miRNA profiling of Macaca mulatta intact colon samples during acute SIV infection

Project description:This study describes differential miRNA expression in intact colon tissue during acute SIV infection of rhesus macaques. Nine miRNAs were found to be significantly affected by infection, with 5 down-regulated and 4 up-regulated miRNAs. The expression of one upregulated miRNA was further characterized and found to be significantly elevated specifically in response to SIV replication and not immune activation/inflammation accompanying SIV infection. We performed TaqMan Low Density Array based high throughput miRNA analysis on intact colon tissue from 10 acutely SIV-infected and 5 uninfected control macaques. All SIV-infected animals were inoculated intravenously with 100TCID50 of SIV. Out of the ten, one animal each was at 7, 8 and 10DPI (days post infection), 3 each at 13 and 21DPI, and 1 at 29DPI. microRNA reverse transcription and preamplification was performed according to the manufacturerM-bM-^@M-^Ys recommendation. Data analysis was performed using RQ Manager 1.2.2 and DataAssist v3.01 software. Data was normalized using Global normalization method and multiple comparisons correction was performed using Benjamini-Hochberg method.

miRNA expression changes in small intestinal lamina propria leukocyte samples during the course of SIV infection of rhesus macaques

Project description:This study describes differential miRNA expression in small intestinal lamina propria leukocyte samples longitudinally during the course of SIV infection of rhesus macaques. Notably, the T-cell activation associated miR-15b, miR-142-3p, miR-142-5p and miR-150 expression was significantly downregulated at 90 and 180DPI. Further, reporter and overexpression assays validated IRAK1 as a direct miR-150 target. Furthermore, IRAK1 protein levels were markedly elevated in intestinal LPLs and epithelium. Finally, blockade of CD8+ T-cell activation/proliferation with delta-9 tetrahydrocannabinol (ï9-THC) significantly prevented miR-150 downregulation and IRAK1 upregulation. Our findings suggest that miR-150 downregulation during T-cell activation may disrupt the translational control of IRAK1 facilitating persistent GI inflammation. We performed TaqMan Low Density Array based high throughput miRNA analysis on small intestine tissue from 12 chronically SIV-infected and 4 uninfected control macaques. All SIV-infected animals were inoculated intravenously with 100TCID50 of SIV. Out of the ten, one animal each was at 7, 8 and 10DPI (days post infection), 3 each at 13 and 21DPI, and 1 at 29DPI. microRNA reverse transcription and preamplification was performed according to the manufacturerâs recommendation. Data analysis was performed using RQ Manager 1.2.2 and DataAssist v3.01 software. Data was normalized using Global normalization method and multiple comparisons correction was performed using Benjamini-Hochberg method.

Effect of milk intake on circulating plasma miRNAs of adult humans

Project description:This study examines circulating plasma miRNAs of adult human subjects before and after bovine milk intake. We sought to confirm and expand findings previously reported by Baier, et al., J Nutr, 2014, PMID 25122645, using the same samples. Plasma samples were provided by the Zempleni lab (see Baier, et al., J Nutr, 2014, PMID 25122645) and had been taken from five healthy donors prior to milk intake (T0) and at three hours post-intake (T3). miRNA profiles were generated for each sample by OpenArray (Thermo Fisher).

MiRNA expression profiles of trophoblastic cells

Project description:To gain more insight in the expression and role of microRNAs in trophoblastic cells, we have assessed the miRNA expression pattern of four trophoblastic cell lines and have compared them with the miRNA signature of human isolated 3rd trimester cytotrophoblast cells. Total RNA was reverse-transcribed, pre-amplified with miRNA-specific primers, and loaded into TLDA cards. Quantitative real-time PCR was performed for 768 miRNAs. For each of two cards per sample (A and B), 9 ul of pre-amplified diluted sample was mixed with TaqMan reaction mix (Applied Biosystems) and loaded into miRNA TLDA cards (Applied Biosystems) by centrifugation. Cards were sealed, and qRT-PCR was performed at a real-time thermocycler (ABI-7900, Applied Biosystems) following the manufacturer's recommendations. MiRNA signatures of human primary 3rd trimester trophoblast cells were compared with those of four trophoblastic cell lines
