Using transgenic mice expressing GFP in cycling cells we sorted live, replicating beta-cells and determined their transcriptome. Replicating beta-cells upregulate hundreds of proliferation- related genes, along with many novel putative cell cycle components. Strikingly, genes involved in beta-cell functions, namely glucose sensing and insulin secretion were repressed. Further studies using single molecule RNA in situ hybridization revealed that in fact, replicating beta-cells double the amount of RNA for most genes, but this upregulation excludes genes involved in beta-cell function.

  • Clinical Implications of Next-Generation Sequencing for Cancer Medicine
    NEXT-GENERATIONUPDATES SEQUENCING AND DEVELOPMENTS AND CANCER MEDICINE IN ONCOLOGY Clinical implications of next-generation sequencing for cancer medicine † A. Shuen HBS c MD * and W.D. Foulkes MBBS PhD* KEY WORDS method of sequencing DNA , limiting the ability to comprehensively detect cancer-causing mutations. It Next-generation sequencing, cancer genome, person- was not until advances were made in nanotechnology, alized medicine biochemistry, imaging, and bioinformatics that sec- ond-generation massively parallel sequencing made ~ screening for such mutations possible at reasonable cost and within a reasonable time period. In 1976, Peter Nowell, following observations of Unlike Sanger sequencing, NGS circumvents the cytogenetic heterogeneity in a population of cancer- rate-limiting step of separating randomly terminated ous cells, proposed that this genetic diversity could polymerase chain reaction amplicons by capillary be explained by hypothesizing that these cells are pore electrophoresis. Conceptually, NGS technology is subject to evolutionary forces 1. He posited that clonal based on the simultaneous sequencing of millions of expansion of a malignant cell with acquired genetic randomly cleaved fragments of the genome by read- instability could give rise to various subpopulations, ing the nucleotides as they are incorporated in situ, and with subsequent selection for phenotypes having computationally reconstructing the DNA fragments, a proliferative advantage. This insight led to his effectively producing a nucleotide resolution of the prediction that therapy may need to be individually genome. This method is particularly suited for cancer tailored according to the unique genetic mosaic that research because it allows the frequency of somatic constitutes a tumour. Now, more than 30 years later, mutations within a population of cancer cells to be with the advent of next-generation sequencing (NGS ), determined (Figure 1).

This results in the formation of a new combined gene. They have been implicated in carcinogenesis in a number of different cancers, though they have been understudied in high grade serous ovarian cancer. This study used high throughput tools to compare the transcrip- tome of high grade serous ovarian cancer and normal fallopian tubes in the interest of identifying unique fusion transcripts within each group. Indeed, we found that there were significantly more fusion transcripts in the cancer samples relative to the normal fallopian tubes. Following this, the Citation: Newtson, A.; Reyes, H.; role of fusion transcripts in chemo-response and overall survival was investigated. This led to the Devor, E.J.; Goodheart, M.J.; Bosquet, identification of fusion transcripts significantly associated with overall survival.
