ACS Synthetic Biology

1. (2014) Conditional control of mammalian gene expression by tetracycline- dependent hammerhead ribozymes. Kim Beilstein, Alexander Wittmann, Manuel Grez, et al. ACS Synthetic Biology. Published online ahead of print. Link.
   Summary: The authors demonstrated the functionality of a 3'-UTR rybozyme that results in correct folding of the mRNA after addition of tet. Important because the mammalian synthetic biology toolbox is limited so more parts are valuable (even though this want can't really be used with the well-characterized TetR system), eliminates basal pTet expression, and it removes an integration step for building a transgenic inducible system.
   
   
2. (2014) Environmental Sensing of Heavy Metals Through Whole Cell Microbial Biosensors: A Synthetic Biology Approach Lara Bereza-Malcolm, Gulay Mann, and Ashley Edwin Franks. ACS Synthetic Biology, Published online ahead of print. Link.
   Summary: People use quorum sensing to build microbial biosensors. Good resource for QS review.
   
   

Cell

1. (2014) Ruled by Ubiquitylation: A New Order for Polycomb Recruitment. Yuri B Schwartz, Vincenzo Pirrotta et al. Cell, 8.2:321-325. Link
   Summary: This paper provides a new way of thinking about Polycomb complexes and how they play a role in gene regulation! Everything we currently know about polycomb complex recruitment is going to be challenged. The recruitment of polycomb complexes have always been studied in two steps. First, the PRC2 produces histone H3K27 trimethylation at a specific gene, then, the PRC1 complex is recruited by its ability to bind to H3k27me3. However, there have been articles that contradict this process by focusing on a variant of the PRC1 complex and H2A ubiquitylation of surrounding chromatin in the recruitment of PRC2 and H3k27.
   
   
2. (2014) Generation of Functional Human Pancreatic β Cells in Vitro. Felicia W. Paglicua, Jeffery R. Millman, Mads Gurtler et al. Cell, 159:2, 428-439. [1]
   Summary: Attn. David; This research focused on generating glucose responsive β cells from hPSC with limited genetic differences. This, of course, could play a very important role in diabetes treatment.

Nature Methods

1. Chemically defined generation of human cardiomyocytes

Summary: The researchers looked at a commonly used supplement in cell culture, B27, which has 27 different components, and identified only two that had any impact on cardiomyocyte differentiation: L-ascorbic acid 2-phosphate (a form of Vitamin C) and rice-derived recombinant human albumin. They used these two supplements in base RPMI medium to grow up TNNT2-positive cardiomyocytes with reported 95% efficency.

Nothing super relevant.
Perhaps a bit relevant to Jan/David

1. (2014) Mitosis Gives a Brief Window of Opportunity for a Change in Gene Transcription Richard P. Halley-Stott, Jerome Jullien, Vincent Pasque et al. PLoSBio. 12(7). Link.
   Summary: Found that mitotic chromatin (which has most transcription factors temporarily displaced) is reprogrammed 100 times faster than interphase nuclei in post-nuclear transfer to amphibian oocytes. Genes pass through a transient phase of high responsiveness to reprogramming factors during mitosis which alters cell fates and is an opportunity for reprogramming to pluripotency. This may be a result of histone H2A deubiquitination.

1. (2014) H3K27me and PRC2 transmit a memory of repression across generations and during development. Laura J. Gaydos, Wenchao Wang2, Susan Strome. Science. 345 no. 6203 pp. 1515-1518 . Link.
   Summary: Attn. Jonah; Studied gene repression via methylation of H3K27me by PRC2. Generated embryos containing chromosomes with and without H3K27me. Without PRC2, H3K27me was transmitted to daughter chromatids through several rounds of cell division rather than the mosaic H3K27 pattern through embrygensis present in embryos with PRC2. Suggests that PRC2 represses X chromosomes in Caenorhabditis elegans germ cells. Shows that H3K27me and PRC2 both contribute to transmitting memory of repression across generations epigenetically.

   Summary: Attn. David; Explored efficiency of reprogramming events for cell conversion in vitro. Found conversion requires stepwise histone-modifying activities partitioned into fragmented phases of transdifferentiation through nuclear degradation of JMJD-3.1 and interactions with transcription factors at particular phases relevant in fate selection. Studied H3K27me3.
