The present invention provides a method of identifying origin of a metastasis of unknown origin by obtaining a sample containing metastatic cells; measuring Biomarkers associated with at least two different carcinomas; combining the data from the Biomarkers into a linear discrimination analysis where the linear discrimination analysis normalizes the Biomarkers against a reference; and imposes a cut-off which optimizes sensitivity and specificity of each Biomarker, weights the prevalence of the carcinomas and selects a tissue of origin determining origin based on highest probability determined by the linear discrimination analysis or determining that the carcinoma is not derived from a particular set of carcinomas; and optionally measuring Biomarkers specific for one or more additional different carcinoma, and repeating the steps for additional Biomarkers.

— According to Stratistics MRC, the Global Circulating Tumor Cells Market is accounted for $4.41 billion in 2015 and is expected to reach $17.96 billion by 2022 growing at a CAGR of 19.2 % from 2015 to 2022. The rising demand for high Benefit-Cost Ratio (BCR) associated with CTCs prognostic technology is the major factor boosting the market growth. Furthermore, advancements in biomedical imaging and bioengineering technology are some of the key factors driving the market. However, high cost associated with the diagnosing and reluctance among people towards adopting highly developed prognostic technologies inhibit the market growth. The recent trends in global Circulating Tumor Cells are strengthening distribution network of CTCs prognostic technologies in emerging economies and the technical advancement of CTCs-based customized medicines. Tumor cell detection is the foremost product segment primarily due to the advantages related with therapeutic monitoring and high procedure prices. North America region is expected to witness highest growth rate during the forecast period due to increasing demand in number of research projects. In addition, the U.S. Government also supports research by funding various institutes, which grant research funds. Some of the key players in the market include Adnagen AG, Advanced Cell Diagnostics, Apocell, Aviva Biosciences, Biocep Ltd., Biocept Inc., Biofluidica, Canopus Biosciences, CellTraffix Inc., Clearbridge BioMedics, Creatv Microtech Inc., Cynvenio Biosystems Inc. , Epic Biosciences, Fluxion Biosciences., Greiner Bio-One GmbH, Ikonisys Inc., IV Diagnostics Inc., Janssen Diagnostics, Miltenyi Biotech and Nanostring Technologies Inc.

Polyomaviruses are a family of non-enveloped DNA viruses infecting several species, including humans, primates, birds, rodents, bats, horse, cattle, raccoon and sea lion. They typically cause asymptomatic infection and establish latency but can be reactivated under certain conditions causing severe diseases. MicroRNAs (miRNAs) are small non-coding RNAs that play important roles in several cellular processes by binding to and inhibiting the translation of specific mRNA transcripts. In this review, we summarize the current knowledge of microRNAs involved in polyomavirus infection. We review in detail the different viral miRNAs that have been discovered and the role they play in controlling both host and viral protein expression. We also give an overview of the current understanding on how host miRNAs may function in controlling polyomavirus replication, immune evasion and pathogenesis. © 2013 Lagatie et al.; licensee BioMed Central Ltd.

JC virus is a human polyomavirus that infects the majority of people without apparent symptoms in healthy subjects and it is the causative agent of progressive multifocal leucoencephalopathy (PML), a disorder following lytic infection of oligodendrocytes that mainly manifests itself under immunosuppressive conditions. A hallmark for JC virus isolated from PML-brain is the presence of rearrangements in the non-coding control region (NCCR) interspersed between the early and late genes on the viral genome. Such rearrangements are believed to originate from the archetype JC virus which is shed in urine by healthy subjects and PML patients. We applied next generation sequencing to explore the non-coding control region variability in urine of healthy subjects in search for JC virus quasispecies and rearrangements reminiscent of PML. For 61 viral shedders (out of a total of 254 healthy subjects) non-coding control region DNA and VP1 (major capsid protein) coding sequences were initially obtained by Sanger sequencing. Deletions between 1 and 28 nucleotides long appeared in ∼24.5% of the NCCR sequences while insertions were only detected in ∼3.3% of the samples. 454 pyrosequencing was applied on a subset of 54 urine samples demonstrating the existence of JC virus quasispecies in four subjects (∼7.4%). Hence, our results indicate that JC virus DNA in urine is not always restricted to one unique virus variant, but can be a mixture of naturally occurring variants (quasispecies) reflecting the susceptibility of the non-coding control region for genomic rearrangements in healthy individuals. Our findings pave the way to explore the presence of viral quasispecies and the altered viral tropism that might go along with it as a potential risk factor for opportunistic secondary infections such as PML. © 2013 Van Loy et al.

The disclosed edge-blocker oligonucleotide based AS-NEPB-PCR method amplifies allele specific DNA (or RNA) while dramatically blocking amplification of wild type (WT) DNA (or RNA). The AS-NEPB-PCR design allows ready modification of an existing PCR reaction setup with an edge-blocker oligonucleotide together with an allele specific primer complementary to the mutant sequence to achieve allele specific amplification. The method simplifies assay optimization procedures and achieved sensitivity sufficient to detect a signal present at 0.1% level with close to 100% specificity, which is useful in detecting SNP or genetic mutations. The method was used to detect three different genetic mutations in cancer, in KRAS, BRAF, and EGFR, with three different types of modified edge-blocker oligonucleotides (phosphate, inverted dT and amino-C7). It was possible to detect one copy of mutant DNA in 1000-copy of normal DNA background of a heterogeneous sample, and was far more sensitive than the other blocking method.
