Altered Chromatin Occupancy of Master Regulators Underlies Evolutionary Divergence in the Transcriptional Landscape of Erythroid Differentiation

18.12.2014 | Jacob C. Ulirsch et al., PLoS Genetics, 2014

by Jacob C. Ulirsch, Jessica N. Lacy, Xiuli An, Narla Mohandas, Tarjei S. Mikkelsen, Vijay G. Sankaran Erythropoiesis is one of the best understood examples of cellular differentiation. Morphologically, erythroid differentiation proceeds in a nearly identical fashion between humans and mice, ...

Global Analysis of Photosynthesis Transcriptional Regulatory Networks

11.12.2014 | Saheed Imam et al., PLoS Genetics, 2014

by Saheed Imam, Daniel R. Noguera, Timothy J. Donohue Photosynthesis is a crucial biological process that depends on the interplay of many components. This work analyzed the gene targets for 4 transcription factors: FnrL, PrrA, CrpK and MppG (RSP_2888), which are known or predicted to control ...

Rgs6 is Required for Adult Maintenance of Dopaminergic Neurons in the Ventral Substantia Nigra

11.12.2014 | Panojot Bifsha et al., PLoS Genetics, 2014

by Panojot Bifsha, Jianqi Yang, Rory A. Fisher, Jacques Drouin Parkinson disease (PD) is characterized by the preferential, but poorly understood, vulnerability to degeneration of midbrain dopaminergic (mDA) neurons in the ventral substantia nigra compacta (vSNc). These sensitive mDA neurons ...

Maf1 Is a Novel Target of PTEN and PI3K Signaling That Negatively Regulates Oncogenesis and Lipid Metabolism

11.12.2014 | Beth M. Palian et al., PLoS Genetics, 2014

by Beth M. Palian, Aarti D. Rohira, Sandra A. S. Johnson, Lina He, Ni Zheng, Louis Dubeau, Bangyan L. Stiles, Deborah L. Johnson Maf1 was initially identified as a transcriptional repressor of RNA pol III-transcribed genes, yet little is known about its other potential target genes or its ...

The rem Mutations in the ATP-Binding Groove of the Rad3/XPD Helicase Lead to Xeroderma pigmentosum-Cockayne Syndrome-Like Phenotypes

11.12.2014 | Emilia Herrera-Moyano et al., PLoS Genetics, 2014

by Emilia Herrera-Moyano, María Moriel-Carretero, Beth A. Montelone, Andrés Aguilera The eukaryotic TFIIH complex is involved in Nucleotide Excision Repair and transcription initiation. We analyzed three yeast mutations of the Rad3/XPD helicase of TFIIH known as rem (recombination and mutation ...
