Chromatin Dynamics in Lineage Commitment and Cellular Reprogramming
Dynamic structural properties of chromatin play an essential role in defining cell identity and function. Transcription factors and chromatin modifiers establish and maintain cell states through alteration of DNA accessibility and histone modifications. This activity is focused at both gene-proximal promoter regions and distally located regulatory elements. In the three-dimensional space of the...
متن کاملChromatin Connections to Pluripotency and Cellular Reprogramming
The pluripotent state of embryonic stem cells (ESCs) provides a unique perspective on regulatory programs that govern self-renewal and differentiation and somatic cell reprogramming. Here, we review the highly connected protein and transcriptional networks that maintain pluripotency and how they are intertwined with factors that affect chromatin structure and function. The complex interrelation...
متن کاملCellular Reprogramming toward the Erythroid Lineage
Haemoglobinopathies such as thalassaemia and sickle cell disease present a major health burden. Currently, the main forms of treatment for these diseases are packed red blood cell transfusions and the administration of drugs which act to nonspecifically reactivate the production of foetal haemoglobin. These treatments are ongoing throughout the life of the patient and are associated with a numb...
متن کاملSetd1a and NURF mediate chromatin dynamics and gene regulation during erythroid lineage commitment and differentiation
The modulation of chromatin structure is a key step in transcription regulation in mammalian cells and eventually determines lineage commitment and differentiation. USF1/2, Setd1a and NURF complexes interact to regulate chromatin architecture in erythropoiesis, but the mechanistic basis for this regulation is hitherto unknown. Here we showed that Setd1a and NURF complexes bind to promoters to c...
متن کاملCellular Reprogramming: Chromatin Puts On the Brake
Directed reprogramming of differentiated cells allows the generation of specific cell types for therapeutics and can provide unexpected insights into development. A recent study demonstrates that efficient reprogramming of Caenorhabditis elegans germ cells into neurons can be achieved by knocking down a histone chaperone gene and ectopic expression of a terminal selector transcription factor.
