Processing apples into food products leaves behind pomace – the skin, seeds, core, stems and soft tissue of the fruit.
An interaction network was generated that highlighted Gata2 as a core stem cell regulator, and examination of Gata2 heterozygotes indicated that the stem cell network is sensitive to modulations in the expression of individual TFs: transcriptional changes were identified consistent with the known expression pattern and function of Gata2 in regulating megakaryocyte-erythroid development.
BRD4 regulates ESC self-renewal and expression of pluripotency genes Inhibition of BRD4 results in commitment to the neuroectodermal lineage BRD4 occupies SEs of core stem cell genes and recruits active transcription complexes BRD4 controls transcriptional elongation of SE-associated pluripotency genes.
The value of the "core" Stem (science, tech, engineering and maths) approach has been pitted against the Steam approach (the "a" is for arts).
In this review, we discuss the roles of various DUBs involved in the regulation of core stem cell transcription factors and CSC-related proteins that are implicated in the modulation of cellular processes and carcinogenesis.
Rather, it reflects a range of behavioral, social, economic, and occupational factors that, at their core, stem from differences in education and social class.
The variability is not based on good luck or genes: "Rather it reflects a range of behavioural, social, economic and occupational factors that, at their core, stem from differences in education and social class".
Moreover, EGFR transcripts were found down regulated in DiI+/SCCs demonstrating differential activity of core stem cell pathways between DiI+/SCCs and DiI−/FCCs.
BRD4 maintains transcription of core stem cell genes such as OCT4 and PRDM14 by occupying their super-enhancers (SEs), large clusters of regulatory elements, and recruiting to them Mediator and CDK9, the catalytic subunit of the positive transcription elongation factor b (P-TEFb), to allow Pol-II-dependent productive elongation.
The concept of "stemness" (term introduced in 1986 by Grossman & Levine) is defined as "core stem cell properties that underlie self-renewal and the ability to generate differentiated progeny" [ 22].
