- (2012) Engineered cell-cell communication via DNA messaging. Monica Ortiz, Drew Endy at Stanford (No permanent link yet). Summary: Used bacteriophage M13 gene products to send DNA messages that encoded different messages to F+ bacteria. Could be useful if you could control when the message is sent, like in the presence of some compound.
- (2012) A genetic bistable switch utilizing nonlinear protein degradation. Daniel Huang, William Holtz, Michel Maharbiz from Department of Electrical Engineering and Computer Science at Berkeley Link. Summary: Made a bistable switch where the bistability depends on protein degradation. Used Lon protease which will not interfere with endogenous E. coli that targets a specific degradation tag that will not be targeted by endogenous E. coli proteases (no cross talk). Argue that using protein degradation to flip a switch is better than heat shock and UV because it won't damage the rest of the cell.

- (2012) Activating Transcription Factor 3 Regulates Immune and Metabolic Homeostasis. Jan Rynesa, Colin D. Donohoea, Peter Frommoltc, Susanne Brodesserd, Marek Jindrae and Mirka Uhlirovaa. MCB Molecular and Cellular Biology 2012 32.19:3949-3962. Link. Summary: Group studying the loss of Atf3 within Drosophila and how it affects the metabolic, immunity, and other related systems.
- (2012) Origins and Formation of Histone Methylation across the Human Cell Cycle. Barry M. Zeea, Laura-Mae P. Brittona, Daniel Wollea, Devorah M. Habermanb and Benjamin A. Garciaa. MCB Molecular and Cellular Biology 2012 32.21: 2503-2514. Link. Summary: The connections between various nuclear processes and speciﬁc histone posttranslational modiﬁcations are dependent to a large extent on the acquisition of those modiﬁcations after histone synthesis.
- (2012) A map of nucleosome positions in yeast at base-pair resolution. Kristin Brogaard, Liqun Xi, Ji-Ping Wang, and Jonathan Widom. Nature 2012 0:1-6. Link. Summary: A more accurate method developed for mapping nucleosome centers based on chemically modifying engineered histones.
- (2012) Chromatin organization is a major influence on regional mutation rates in human cancer cells. Benjamine Schuster-Bockler and Ben Lehner. Nature 2012 488: 504-507. Link. Summary: There is a strong relationship between chromatin organization and mutation rates. The amount of somatic mutations correlates to histone modification levels and anti-correlates with open chromatin's genomic features.

- (2012) Asymmetric positive feedback loops reliably control biological responses. Alexander V Ratushny, Ramsey A Saleem, Katherine Sitko, Stephen A Ramsey & John D Aitchison. Nature Molecular Systems Biology 2012 8:577. Link. Summary: They studied both experimentally and using computational modeling, the behavior of systems controlled by the ASSURE I or II motif and systems in which both regulatory molecules in the pair are self-upregulated.
- (2012) A regulatory role for repeated decoy transcription factor binding sites in target gene expression. Lee TH, Maheshri N. Nature Molecular Systems Biology 2012 8:576. Link. Summary: They used the synthetic tet–OFF system in budding yeast to study how repeated arrays of tetO decoy sites influenced expression of tTA-inducible tetO promoters.

- (2012) Systematic Dissection of Roles for Chromatin Regulators in a Yeast Stress Response. Assaf Weiner, Hsiuyi Chen, Chih Long Liu, and Ayelet Rahat et al. PLOS Biology 2012 10.7: Link Summary: Gene expression is tested in 200 chromatin mutants during a yeast stress response. Studies indicate that gene expression is greatly affected compared to steady-state transcription.
