Redox-dependent transcriptional regulation.
Reactive oxygen species contribute to the pathogenesis of a number of disparate disorders including tissue inflammation, heart failure, hypertension, and atherosclerosis. In response to oxidative stress, cells activate expression of a number of genes, including those required for the detoxification of reactive molecules as well as for the repair and maintenance of cellular homeostasis. In many ...
متن کاملContext-Dependent Genetic Regulation
Cells process extra-cellular signals with multiple layers of complex biological networks. Due to the stochastic nature of the networks, the signals become significantly noisy within the cells and in addition, due to the nonlinear nature of the networks, the signals become distorted, shifted, and (de-)amplified. Such nonlinear signal processing can lead to non-trivial cellular phenotypes such as...
متن کاملTlx3 exerts context-dependent transcriptional regulation and promotes neuronal differentiation from embryonic stem cells.
The T cell leukemia 3 (Tlx3) gene has been implicated in specification of glutamatergic sensory neurons in the spinal cord. In cranial sensory ganglia, Tlx3 is highly expressed in differentiating neurons during early embryogenesis. To study a role of Tlx3 during neural differentiation, mouse embryonic stem (ES) cells were transfected with a Tlx3 expression vector. ES cells stably expressing Tlx...
متن کاملZinc-Dependent Transcriptional Regulation in Paracoccus denitrificans
Zinc homeostasis is critical for bacterial survival and is mediated largely at the transcriptional level by the regulation of zinc uptake and efflux genes. Here we use RNA-seq to assess transcriptional changes as a result of zinc limitation in the denitrifying bacterium Paracoccus denitrificans. The results identify the differential expression of 147 genes, most of which were upregulated in zin...
متن کاملTranscriptional regulation in the context of chromatin structure.
A wide variety of histone-like proteins can be assembled into nucleosomal structures. Core and linker histone variants, proteins of the histone-fold and winged-helix families can all contribute to the local differentiation of functional chromosomal domains. It is very difficult to disrupt core histone interactions within a nucleosome in vivo. Histones H3 and H4 do not exchange out of chromatin ...
