(Submitter supplied) Transcriptome analysis of partially degraded and fragmented RNA samples from body fluids Global gene expression profiling has shown great promise in high-throughput biomarker discovery for early disease detection in body fluids such as saliva, which is accessible, cost-effective, and non-invasive. However, this goal has not been fully realized because saliva, like many clinical samples, contains partially fragmented and degraded RNAs that are difficult to amplify and detect with prevailing technologies. more...

(Submitter supplied) A sensitive assay to identify biomarkers that can accurately diagnose the onset of breast cancer using non-invasively collected clinical specimens is ideal for early detection. In this study, we have conducted a prospective sample collection and retrospective blinded validation (PRoBE design) to evaluate the performance and translational utilities of salivary transcriptomic and proteomic biomarkers for the non-invasive detection of breast cancer. more...

(Submitter supplied) Ovarian cancer is the leading cause of death in gynecological diseases, and has been considered as one of the most fatal cancers due to lack of reliable detection strategy in the early stage. Therefore the capability to detect the morbidity initiation with an sensitive and effective approach is one of the most desirable goals for curing ovarian cancer. In this study, we used microarray technology for salivary mRNA biomarkers discovery, and evaluated the performance and translational utilities of discovered markers from a clinical study using an independent sample cohort . more...

(Submitter supplied) Pancreatic cancer is the fourth leading cause of cancer death. Lack of early detection technology for pancreatic cancer invariably leads to a typical clinical presentation of incurable disease at initial diagnosis. Oral fluid (saliva) meets the demand for non-invasive, accessible, and highly efficient diagnostic medium. The level of salivary analytes, such as mRNA and microflora, vary upon disease onset; thus possess valuable signatures for early detection and screening. more...

(Submitter supplied) We have performed gene expression microarray analysis to profile transcriptomic signatures between cancer and noncancerous patients Gastric cancer is currently the second leading cause of cancer deaths. Due to the difficulty of diagnosing patients in the early stages of gastric cancer, it is critical to develop a method that can diagnose the disease at the early stage to allow for better treatment options. more...

(Submitter supplied) 41% of all oral carcinomas have been found to localize at tongue, where they were characterized as being aggressive and having capacity to locally invade and relapse frequently. Despite considerable enhancements in the cancer diagnosis and treatment techniques, tongue squamous cell carcinoma (TSCC) still remains to be one of the most common and lethal cancer types in the head and neck region. In this study, we aimed to identify a signature of saliva-specific microRNAs (miRNAs) expression in TSCC patients. more...

(Submitter supplied) Background:Alternative splicing and isoform level expression profiling is an emerging field of interest within genomics. Splicing sensitive microarrays, with probes targeted to individual exons or exon-junctions, are becoming increasingly popular as a tool capable of both expression profiling and finer scale isoform detection. Despite their intuitive appeal, relatively little is known about the performance of such tools, particularly in comparison with more traditional 3’ targeted microarrays. more...

(Submitter supplied) Exonic profiling is an emerging topic in disease-associated transcriptome analysis, but is still facing major limitations. In this study, we performed a microarray-based analysis of the transcriptome at the exon level of mouse primary mammary tumors having different abilities to give rise to metastases. First, we developed a bioinformatics platform and used a stringent algorithm to identify 679 genes with differentially expressed exons in primary tumors of the 4T1 mouse model of mammary tumor progression. more...

(Submitter supplied) Early surgery is vital in the treatment of highly fatal pancreatic cancer (PC). But there is no valuable and non-invasive biomarker to screen PC currently. Studies showed many salivary molecules can detect several systemic diseases. We aimed to investigate whether salivary microRNAs (miRNAs) can act as a biomarker to detect resectable PC.

(Submitter supplied) Saliva (oral fluids) is an emerging biofluid poised for clinical diseases detection. Although the rationale for oral diseases applications (e.g. oral cancer) is clear, the rationale and relationship between systemic diseases and saliva biomarkers are unknown. In this study, we used mouse models of melanoma and non-small cell lung cancer and compared the transcriptome biomarker profiles of tumor-bearing mice to those of control mice. more...

(Submitter supplied) RNA stabilizing reagents have been developed to ensure that transcription profiles of whole blood samples reflect the physiological state at the time of the blood drawn. Ability to preserve and maintain the in vivo gene expression status ex vivo is essential for gene expression profiling and biomarker discovery from clinical sample material.

(Submitter supplied) Aberrant splice variants are involved in the initiation and/or progression of glial brain tumors. We therefore set out to identify splice variants that are differentially expressed between histological subgroups of gliomas. Splice variants were identified using a novel platform that profiles the expression of virtually all known and predicted exons present in the human genome. Exon-level expression profiling was performed on 26 glioblastomas, 22 oligodendrogliomas and 6 control brain samples. more...

(Submitter supplied) Circulating RNAs are a less invasive and easy accessed source of samples for biomedical research and clinical applications. However, circulating mRNA is mostly fragmented and less abundant. High throughput RNA sequencing (RSEQ) and DASL assay have been both applied to profile such fragmented RNA samples. In this study, we compared the ability of transcriptomic profiling of the two platforms. Circulating RNAs from three non-small cell lung cancer patients and three age-matched healthy controls were analyzed by RSEQ and DASL assay. more...

(Submitter supplied) 71 liver RNA samples from three mouse strains - DBA/2J, C57BL/6J and C3H/HeJ - were profiled using a custom-designed microarray monitoring exon and exon-junction expression of 1,020 genes representing 9,406 exons. Gene expression was calculated via two different methods, using the 3'-most exon probe ("3' gene expression profiling") and using all probes associated with the gene ("whole-transcript gene expression profiling"), while exon expression was determined using exon probes and flanking junction probes that spanned across the neighboring exons("exon expression profiling"). more...
