    Summary: Researchers at Harvard have developed a technique known as "Protein Interaction Quantification" that can analyze genome-wide DNAse hypersensitivity data. This technique is a high-throughput version of CHIP-Seq that compares DNAse-seq data to a reference genome. Using machine-learning algorithms that factor the shape of all known transcription factors into the calculations, protein interaction quantification predicts the probability that a specific transcription factor occupies a specific section of the genome. This technique is directly relevant to the Haynes lab as a high-throughput method of probing changes in chromatin architecture.Commentary on the article: Link

Science

  1. (2014) A Cascade of Histone Modifications Induces Chromatin Condensation in Mitosis. Bryan J. Wilkins, Nils A. Rall1, Yogesh Ostwal et al. Science. 343:77-80. Link.
    Summary: Examined the driving forces of chromatin hypercondensation during mitosis by inserting ultraviolet light inducible cross-linker amino acids in histone proteins of living yeast to trace interactions of proteins along the cell cycle. Found that H3 S10 phosphorylation leads to recruitment of the histone deacetylase Hst2p which removes an acetyl group from histone H4 lysine 16, allowsing the H4 tail to promote fiber condensation on the surface of neighboring nucleosomes. This series of reactions yields a condensin-independent driving force of chromatin hypercondenation during mitosis (where previously it was thought that metaphase chromosome condensation required the condensin complex to remain undisrupted). Although the chromatin marker being researched in this article is H3S10 rather than our marker of interest in the Haynes lab (H3K27me3) I thought the use of ultra violet light could be relevant to Branden's project (although I'm unsure of the details of his work so this may not be the case).

  2. (2014) Total Synthesis of a Functional Designer Eukaryotic Chromosome. Narayana Annaluru, Héloïse Muller, Leslie A. Mitchell et al. Science. 344:55-58. Link.
    Summary: Designer eukaryotic chromosome synthesized based on native Saccharomyces cerevisiae chromosome III. This chromosome is functional in S.cerevisiae. All nonessential genes were made to be flanked by loxPsym sites which enabled inducible evolution and genome reduction; this allows for direct evolutionary testing (e.g. max number of nonessential genes that can be modified or deleted without a catastrophic loss of fitness). This chromosome synthesis is a major and exciting step forward in synthetic biology. Authors postulate that it will soon be feasible to engineer new eukaryotic genomes with synthetic chromosomes encoding desired function and phenotypic properties. Another very exciting component of this breakthrough is that it was accomplished by undergraduate students, demonstrating the significant power of open sourced work and brain pooling.

  3. (2013) Genetics Driving Epigenetics. Terrence S. Furey, Praveen Sethupathy. Science. 342:705-706. Link.
    Summary: I don't think this article needs to be discussed in the meeting, however I thought it was a good (and very short) background on how DNA sequence variation influences epigentics through transcription factor modulated histone tail modificatons and epigenetic mechanisms in general. I would recommend lab members not already familiar with this topic to read it!

Miscellaneous Reviews and Media

Reviews

  1. (2014) Programming biological operating systems: genome design, assembly and activation. Gibson DG. Nature Methods, 11:521-6. Link
    Summary: REVIEW - Dan Gibson (inventor of Gibson Assembly) published a very nice review on genome building.

    Summary: REVIEW - A very nice review from the Voigt lab exploring the requirements and challenges of building genetic circuits. This review is important and timely because it emphasizes the "circuit-building" aspect of synthetic biology, which sets it apart from traditional genetic engineering.
