Molecular Biology of the Cell
- # 2013 A short carboxyl-terminal tail is required for single-stranded DNA binding, higher-order structural organization, and stability of the mitochondrial single-stranded annealing protein Mgm101. MacMillan Mbantenkhu*, Sara Wierzbicki, Xiaowen Wang, Shangdong Guo, Stephan Wilkens, and Xin Jie Chen. Molecular Biology of the Cell. Link 24: 1507-1518. Summary: This article goes over the carboxyl-terminal tail on the annealing protein Mgm101. Mgm101 is a single-stranded annealing protein (SSAP) that is required for mitochondrial DNA repair. The c-tail is required for the binding of the protein to DNA, stability of the protein and structural organization. The studies on the c-tail could have better implications for how SSAPs help with DNA repair and maintenance.

Mix of analysis of human tissue samples, publicly available ChIP-seq and microarray data, and cell culture experiments to understand how EZH2 expression, a protein subunit of PRC2, can modify cancer cell behavior and predict patient outcomes. They conclude high expression of EZH2 predicts aggressive phenotype, high expression of PRC2 predicts better patient outcome, low expression of PRC2 predicts metastasis..

Found new target sites from HOXB and HOXC that recruit PcG by using a reporter construct. Experiments done in mesenchymal stem cells. Discovered two DNA-binding proteins, JARID2 and YY1, possibly regulate PcG.
- (2013) Effect of natural genetic variation on enhancer selection and function. S. Heinz, C. Benner, and E. Romanoski et al. Nature. Epub ahead of print. Link.
Summary: The study found Inter-individual genetic variation was highly defined by the functioning of lineage determining transcription factors signal-specific binding to enhancer-like regions of the genome. This helps define epigentic and transcriptomic states and prioritizing regulator variants.

Summary: The Jaffrey group was the first to develop and test an RNA that folds into a structure that produces green fluorescence ("Spinach"). In this paper, they report a more stable version, Spinach2, with shows a brighter signal. They used the tag to study the dynamics of "toxic RNA" that is associated with FragileX syndrome.

Summary: This article is a correspondence piece that describes a convenient tool for finding out how your gene of interest is expressed. The data are extracted from the NCBI Gene Expression Omnibus (which is usually very difficult to navigate).

- (2013) Design of orthogonal genetic switches based on a crosstalk map of sigma s, anti-sigma s, and promoters. Virgil A Rhodius, Thomas H Segall-Shapiro, Brian D Sharon, et al. Nature Molecular Systems Biology. 9.702:1-13 Link
A group from the University of California, San Francisco tested 86 extracytoplasmic function sigma factors and 62 anti sigma factors and identified a subset of 20 sigma factors and promoters highly orthogonal to each other.
- (2013) Temporal control of self-organized pattern formation without morphogen gradients in bacteria. Stephen Payne, Bochong Li, Yangxiaolu Cao, et al. Nature Molecular Systems Biology. 9.697:1-10 Link
The majority of biological pattern formation requires morphogens as a spatial cue. A group at Duke University programmed E.coli to instead create a self-organized ring pattern, using the morphogen as a timing cue.

Miscellaneous Reviews and Media
2013 iGEM World Championship - Projects of Interest
- (2013) COLISWEEPER: The world's first bacterial minesweeper game. ETH Zurich iGEM Team. iGEM World Championship. Link.
Summary: Biological version of the Minesweeper game. Bacterial spot-cultures (spaced on a grid on agar) represented either mines or number clues (via expression of some combination of colorimetric enzymes). Quorum sensing (Lux) was used to enable the number clue spots to create a certain color depending upon their positioning near one, two, or more mines. Their data included a nice demonstration of AHL-concentration-dependent gene induction.
- (2013) E. teamwork: Engineering a synthetic microbial consortium. Braunschweig iGEM Team. iGEM World Championship. Link.
Summary: Quroum sensing (Las and Rhl) was used to cross-induce ampicillin resistance in cells so that the survival of each relied on eachother. Cell types were "tagged" with pigment expression (blue and pink) in order to quantify the proportion of each in co-culture. The team reported a third strain (labeled yellow) but I only saw data for a two-strain blue/ pink co-culture on their poster.
- (2013) Exosome mediated mammalian cell-cell communication. MIT iGEM Team. iGEM World Championship. Link.
Summary: The Acyl-TyA peptide tag was used to incorporate proteins into mammalian exosomes, which are vesicles that carry "cargo" from one mammalian cell to another. There is data that suggests that cell membrane localization worked, but no data for actual protein delivery (just tests to see if the tag disrupted protein function).
- (2013) The uniCAS toolkit for gene regulation. Freiburg iGEM Team. iGEM World Championship. Link.
Summary: The team used the Cas9 protein/ guide-RNA system to target various transcriptional regulators to genes in mammalian cells. One very cool, straight-forward application was a split transcription activator: Cas9+CRY2 binds DNA, and CIB1+VP16 is required to activate transcription. Blue light stimulates CRY2-CIB1 interaction; as a result, VP16 recruitment to a gene is controlled by light. Note: the Cas9+Vp16 has been published recently.
