Systematic Evaluation of Medium-Throughput mRNA Abundance Platforms

ABSTRACT: Profiling of mRNA abundances with high-throughput platforms such as microarrays and RNA-Seq has become an important tool in both basic and biomedical research. However these platforms remain prone to systematic errors, and have challenges in clinical and industrial application. As a result it is standard practice to validate a subset of key results using alternate technologies. Similarly, clinical and industrial applications typically involve transitions from high-throughput discovery platform to medium-throughput validation ones. These medium-throughput validation platforms have high technical reproducibility and reduced sample input needs, and low sensitivity to sample-quality (e.g. for processing FFPE specimens). Unfortunately, while medium-throughput platforms have proliferated, there are no comprehensive comparisons of them. Here we present ABI's OpenArray and qPCR systems. TCDD-sensitive (Long-Evans) and TCDD-resistant (Han/Wistar) rats were used in both time-course and dose response studies to asses the transcriptomic response to TCDD-insult. The time-course experiment saw animals recieve a single dose of 100ug/kg TCDD or corn oil vehicle followed by euthanasia and tissue collection at various time-points. Animals in the dose-response experiment recieved a single dose of TCDD at varying concentrations or corn oil vehicle, followed by euthanasia and tissue collection 19 hours post-treatment. Each treatment group contained 4-5 biologicial replicates.

Project description:Signal transducer and activator of transcription 3 (STAT3) is a critical transcription factor in cancer. However, while the protein-coding target genes of STAT3 have been extensively studied, the microRNA target genes of STAT3 are less understood. MicroRNAs are short, non-coding RNAs that regulate messenger RNAs through translational inhibition and transcript degradation. They have been found to be involved in all aspects of cancer biology. Given the roles of both STAT3 and miRNAs in cancer, the function of STAT3 as a transcription factor, and the dearth of known STAT3 miRNA targets, our goal was to identify novel STAT3 miRNA targets relevant to cancer. To do so, we engineered MCF-10A cells with doxycycline-inducible expression of STAT3C. STAT3C is a constitutively-active mutant version of STAT3. Although STAT3 can be activated by various growth factors and kinases, other pathways can be activated as well, which would confound analysis of the results. Thus, the advantage of STAT3C is that it allowed specific and focused activation of STAT3 alone, and this screen represents the first genome-wide survey of miRNA expression changes associated specifically with STAT3 activity. MCF-10A, a non-transformed breast epithelial cell line, was chosen because STAT3C has been reported to be sufficient to cause their neoplastic transformation. Therefore, we reasoned that analysis of STAT3C’s effects in MCF-10A cells would be especially informative for STAT3-regulated miRNAs relevant to cancer. As a result of our study, we identified previously-known as well as novel miRNA targets of STAT3. Doxycycline-inducible MCF-10A cells were seeded, and then untreated (grown in standard growth media alone) or treated with 2?g/ml doxycycline for 48hr. Each condition was performed in biological triplicate (labeled A, B, and C), for a total of 6 samples. Total RNA was harvested and submitted to the Dana-Farber Cancer Institute Molecular Diagnostics Laboratory. MicroRNA expression profiling was performed using TaqMan Low-Density Arrays (TLDA), human miRNA version 2.0A and version 3.0B cards (Applied Biosystems).

Project description:Assessment of the extent to which the altered profiles of miRNA expression influence viral replication and latency, as well as the efficiency of host defenses, may be useful for understanding the basis of the HIV-1-related alterations in cellular physiology and immunologic control. To this end, three patient groups were enrolled. One group consisted of subjects who were classified as M-CM-)lite control long-term non-progressors (M-CM-)LTNP). A second study group was HIV-1-positive subjects, who were antiretroviral therapy naive. A third group was multiply exposed to HIV-1, but uninfected (MEU). This study allowed us to investigate the existence of a CD4+T- lymphocytes miRNAs signature able to discriminate among different stages of HIV-1 infection, and to evaluate whether the exposure to HIV-1 antigen is sufficient to change the miRNA profile. MicroRNAs inhibit HIV-1 expression by either modulating host innate immunity or by directly interfering with viral mRNAs. We evaluated the expression of 377 miRNAs in CD4+ T cells from HIV-1 M-CM-)lite LTNP (M-CM-)LTNP), naive and multiply exposed uninfected individuals (MEU) and we observed that the M-CM-)LTNP patients clustered with naive, whereas all MEU subjects grouped together. The discriminatory power of miRNAs showed that 21 miRNAs significantly differentiated M-CM-)LTNP from MEU and 23 miRNAs distinguished naive from MEU, while only 1 (miR-155) discriminated M-CM-)LTNP from naive. We proposed that miRNA expression may discriminate between HIV-1 infected and exposed but negative individuals. Analysis of miRNAs expression after exposure of healthy CD4+T cells to gp120 in vitro confirmed our hypothesis that a miRNA profile could be the result not only of a productive infection, but also of the exposure to HIV-1 products that leave a signature in immune cells. The comparison of normalized Dicer and Drosha expression in ex vivo and in vitro conditions revealed that these enzymes did not affect the change of miRNA profiles, supporting the existence of a Dicer-independent biogenesis pathway. We have compared miRNA profiles of CD4+ T-lymphocytes from 18 HIV-1-exposed subjects with healthy CD4+ T-lymphocytes following exposure to gp120 using a RT-qPCR assay.

Project description:In the effort to identify novel, relevant prognostic factors for the clinical monitoring of patients affected by squamous cell carcinomas of the oral cavity (SCCOC) we have pursued a molecular screening at the gene and protein level on 166 surgical specimens derived from patients with an accessible clinical history and >2 years follow-up. The screening was focalized on cell surface proteoglycans (PGs) based upon the assumption that altered expression of individual or groups of PGs may predict disease course and therapeutic response, and thereby allow for a clusterization of patients in discrete subsets. The 11 PGs contemplated in the screening and including syndecan-1-4 (SDC1-SDC4), glypican-1-6 (GPC1-GPC6) and NG2, were found to be transcribed at variable levels and with a decreasing frequencies SDC1>SDC4>SDC2>SDC3>GPC4>GPC3>GPC1 >GPC5>CSPG4>GPC6>GPC2. SCCOC cells de novo transcribed GPC2, GPC5 and NG2 and regulated all SDCs, GPC1, -3, -4 and -6, suggesting that an altered surface profile of PG is a characterizing trait of these tumor cells In situ distributional analysis of these PGs on a total of 149 cases revealed many fewer lesions actually translated the molecules which were detected with a frequency range of 14% (SDC2) to 92% (SDC1). Noteworthy was, however, that SDC2 was present in the intra-lesional stroma and in association with neovessels in all the cases, suggesting that this specific PG was a key element of stromal fibroblasts and angiogenic structures. Poor translational efficacy of several of the PGs was accompanied by an apparent retention of the molecules within the cytoplasm of SCCOC cells. This finding suggest that modulated expression of cell surface PGs may be a representative secondary event in SCCOC and that these carcinoma cells do not mount up an effective intracellular machinery for proper shuttling and membrane incorporation of the PGs. A total of 166 surgical specimens of primary SCCOC were collected after informed consent from individuals who underwent surgical removal of the tumor lesions and RNA from 119 surgical specimens were extracted; a pool of RNAs extracted from 5 normal epithelia tissues was adopted as a sample calibrator (HEALTHY sample). cDNA from each samples and from pool of normal epithelial were loaded on TLDA and amplified. HEALTHY sample were amplified 20 times in two replicates (in each TLDA card); each patient sample were amplified 1 time in two replicates and 7 samples of them were loaded two times in a separate TLDA card (for a total of 4 replicates).
