Circulating U2 small nuclear RNA fragments as a novel diagnostic biomarker for pancreatic and colorectal adenocarcinoma

ABSTRACT: Global microRNA expression profiling of serum were collected using Agilent miRNA microarrays (G4471A Human, Amadid 29297, Sanger 14) carrying 887 individual human miRNA probes. Two different sources of RNA were analyzed: serum from NMRI-nu/nu mice carrying a xenograft tumor derived from human primary pancreatic ductal adenocarcinomas (CA, n=6) and serum from tumor free control NMRI-nu/nu mice (N, n=6)

RNASeq analysis of human ALDH- and ALDH+ DU145 xenografts in nu/nu mice upon radiotherapy treatment

Project description:Purpose: we aimed at identify and compare the transcriptional changes of ALDH- and ALDH+ DU145 xenografts upon radiotherapy treatment. Method: Xenografts were generated by injection of ALDH- and ALDH+ DU145 cells in male NMRI-Foxn1 nu/nu immune-deficient mice and subjected to fractionated irradiation to a final dose of 50 Gy. Tumors were excised and processed for total RNA extraction and RNAseq analysis.

Lung miRNA expression profiling in a mouse model of chronic obstructive pulmonary disease

Project description:To profile lung miRNA expression in our mouse model of cigarette smoke-induced chronic obstructive pulmonary disease, we employed the Agilent unrestricted Mouse miRNA (8 x 15k arrays per slide, AMADID Number: 021828, Sanger Version 12) platform as a discovery tool to identify miRNAs of interest in the development of experimental chronic obstructive pulmonary disease. Mice were exposed to cigarette smoke (or room air) for 4, 6, 8, 12 weeks, lungs were excised, and total RNA isolated.

Global microRNA expression profiling of microdissected tissues from diseased and non-diseased pancreatic tissues

Project description:Global microRNA expression profiling of microdissected pancreatic tissues were collected using Agilent miRNA microarrays (G4470B, Sanger 10.1) carrying 723 individual human miRNA probes. Four different sources of RNA were analyzed: microdissected normal pancreatic ductal cells (ND, n=4),microdissected acinar cells (AC, n=4), macrodissected chronic pancreatitis (CP, n=5) and micordissected xenograft tissues derived from primary pancreatic ductal adenocarcinomas (PDAC, n=5).

Serum is preferable to plasma for circulating exosomal microRNA biomarker discovery studies

Project description:Exosomes were purified from 250 ul matched plasma and serum samples using ExoQuickTm. The presence of particles consistent in size with exosomes (60-150nm) was confirmed using a Nanosight LM10. miRNA was extracted from exosomes using an miRNeasy Serum/Plasma kit (Qiagen, #217184). miRNA was reversed transcribed using a TaqMan® microRNA Reverse Transcription Kit (Life technologies, #4366596). miRNA profiling was performed with a high throughput TaqMan® OpenArray® Human microRNA panel (Life technologies, #4461104). The panel consisted of probes for 754 human miRNAs that are based on miRNA sequences derived from Sanger miRBase v14. MegaplexTM Primer Human Pool A v2.1 and Human Pool B v2.0 or v3.0

siRNA profiling of nu/nu after GFP targeted knockdown to examine off target effects of GFP siRNA

Project description:siRNA mediated gene knockdown has been shown to be extremely sequence specific. However, off-target gene regulation due to partial sequence homology has also been reported. Furthermore, sequence unrelated effects on gene regulation can occur when siRNA is applied in vivo. In this experiment we investigated off target gene regulation due to treatment of mice with siRNA and LNA modified siRNA targeting GFP. Off target gene regulation was observed and was markedly reduced upon introduction of LNA modifiecation in siRNA. Experiment Overall Design: NMRI nu/nu mice were treated with saline (control), siRNA or siLNA for three weeks. Then the mice were sacrificed and tumor total RNA was isolated. The effect of siRNA/siLNA treatment was evaluated by comparing gene expression of saline treated animals with that of siRNA and siLNA treated animals respectively.

Immune status, strain background, and anatomic site of innoculation affect mouse papillomavirus (MmuPV1) induction of exophytic papillomas or endophytic trichoblastomas

Project description:Papillomaviruses (PVs) are able to induce papillomas, premalignant lesions, and carcinomas in a wide variety of species. PVs are classified first based on their host and tissue tropism and then their genomic diversities. A laboratory mouse papillomavirus, MmuPV1 (formerly MusPV), naturally infects NMRI-Foxn1nu/Foxn1nu (nude; T cell deficient) mice. C57BL/6J wild-type mice were not susceptible to MmuPV1 infection; however, immunocompetent, alopecic, S/RV/Cri-ba/ba (bare) mice developed small papillomas at injection sites that regressed. NMRI-Foxn1nu and B6.Cg-Foxn1nu but not NU/J-Foxn1nu mice were susceptible to MmuPV1 infection. B6 congenic strains, but not other congenic strains carrying the same allelic mutations, that lack B- and T-cells, but not B-cells alone, were susceptible to infection, indicating that mouse strain and T-cell deficiency are critical to tumor formation. Although lesions initially observed were exophytic papillomas around the muzzle, exophytic papillomas on the tail and condylomas of the vaginal lining could be induced by experimental infections. On the dorsal skin, locally invasive, poorly differentiated tumors developed with features similar to human trichoblastomas. Transcriptome analysis revealed significant differences between the normal skin in these anatomic sites and in papillomas versus trichoblastomas. The primarily dysregulated genes involved molecular pathways associated with cancer, cellular development, cellular growth and proliferation, cell morphology, and connective tissue development and function. Surprisingly, few of the genes commonly associated with basal cell carcinoma or squamous cells carcinoma were dramatically dysregulated.

Micro-RNA expression profiles in upper tract urothelial carcinoma differentiate stage and tumor progression: secondary data set

Project description:Accurate grading and staging of upper tract urothelial carcinoma (UTUC) often proves challenging, and improved knowledge of tumor biology could identify patients who are candidates for minimally invasive therapy rather than nephroureterectomy (NU). Total RNA was extracted from formalin-fixed, paraffin-embedded NU samples. Thirty-five samples with diverse pathologies were selected and screened via microRNA RT-qPCR array for 752 unique miRNA. Validation of differentially expressed miRNA was performed on 123 additional NU tissue specimens from two institutions. The data presented in this series are for the 123 samples analyzed in the validation analysis. The data were normalized to the average of the insignificant control miRNA detected in all samples: miR-125b-5p and miR-185-5p, which were selected from the screening array dataset using NormFinder©.
