and kinase fusions are recurrent events in papillary thyroid cancer of adult population.

Objective: PTC-specific analysis identified novel fusions involving , , , , and genes in adults and pediatric PTCs. Although many novel fusions are PTC-specific events and, therefore, are ideal for diagnosis purposes, validation across additional and larger patient cohorts is essential for introducing these potential diagnostic or prognostic biomarkers into the clinical practice. As most of the , and fusions were initially found in pediatric PTC or in more aggressive thyroid carcinomas, and there is a great disparity across population, in this study, we screened a large set of adult-sporadic PTC cases for the most prevalent kinase fusion lately described in the TCGA.

Quantitative Image Analysis of Single-Molecule mRNA Dynamics in Living Cells.

Single mRNA molecules can be imaged in living cells by a method that consists in genetically inserting binding sites for a bacteriophage protein in the gene of interest. The resulting reporter transgene is then integrated in the genome of cells that express the phage protein fused to a fluorescent tag. Upon transcription, binding of the fluorescent protein to its target sequence makes the RNA visible.

STaQTool: Spot tracking and quantification tool for monitoring splicing of single pre-mRNA molecules in living cells.

The vast majority of human protein-coding genes contain up to 90% of non-coding sequence in the form of introns that must be removed from the primary transcripts or pre-mRNAs. Diverse forms of mRNAs encoded from a single gene are created by the differential use of splice sites and alternative splicing is rapidly evolving. Although the kinetic properties of splicing are thought to be critical for proofreading and regulatory mechanisms, tools for making direct experimental measurements of splicing rates are still limited.

Single-Molecule Live-Cell Visualization of Pre-mRNA Splicing.

Microscopy protocols that allow live-cell imaging of molecules and subcellular components tagged with fluorescent conjugates are indispensable in modern biological research. A breakthrough was recently introduced by the development of genetically encoded fluorescent tags that combined with fluorescence-based microscopic approaches of increasingly higher spatial and temporal resolution made it possible to detect single protein and nucleic acid molecules inside living cells. Here, we describe an approach to visualize single nascent pre-mRNA molecules and to measure in real time the dynamics of intron synthesis and excision.

Single-Molecule Imaging of RNA Splicing in Live Cells.

Expression of genetic information in eukaryotes involves a series of interconnected processes that ultimately determine the quality and amount of proteins in the cell. Many individual steps in gene expression are kinetically coupled, but tools are lacking to determine how temporal relationships between chemical reactions contribute to the output of the final gene product. Here, we describe a strategy that permits direct measurements of intron dynamics in single pre-mRNA molecules in live cells.

Signal transduction proteins in tumors from Puerto Rican and Caucasian gastric adenocarcinoma patients: expression differences with potential for specific targeted therapies.

Overexpression of the HER2/NEU gene is associated with aggressive behavior and poor prognosis in breast cancer, making the Her2/neu protein a directed-therapy target. Tumors of two Puerto Rican (PR) patients overexpressed Her2/neu and resulting partial clinical responses motivated us to compare Her2/neu expression in PR (n = 101) and Caucasian non-Hispanic (n = 95) patients. Immunohistochemistry of tumors showed overexpression of p-Stat3, Cyclin D1, and Her2/neu, compared to non-neoplastic mucosa.
