Background Vertebrate alpha (α)- and beta (β)-globin gene families exemplify the way in which genomes evolve to produce functional complexity. From tandem duplication of a single globin locus, the α- and β-globin clusters expanded, and then were ...

Creating New β-Globin-Expressing Lentiviral Vectors by High-Resolution Mapping of Locus Control Region Enhancer Sequences. [PDF]
Hematopoietic stem cell gene therapy is a promising approach for treating disorders of the hematopoietic system. Identifying combinations of cis-regulatory elements that do not impede packaging or transduction efficiency when included in lentiviral ...

Krüppel-Like Transcription Factor KLF1 Is Required for Optimal γ- and β-Globin Expression in Human Fetal Erythroblasts. [PDF]
In human adult erythroid cells, lower than normal levels of Krüppel-like transcription factor 1 (KLF1) are generally associated with decreased adult β- and increased fetal γ-globin gene expression. KLF1 also regulates BCL11A, a known repressor of adult γ-

Visible Volume: a Robust Measure for Protein Structure Characterization [PDF]
We propose a new characterization of protein structure based on the natural tetrahedral geometry of the β carbon and a new geometric measure of structural similarity, called visible volume.

Minor Loops in Major Folds: Enhancer-Promoter Looping, Chromatin Restructuring, and Their Association with Transcriptional Regulation and Disease. [PDF]
The organization and folding of chromatin within the nucleus can determine the outcome of gene expression. Recent technological advancements have enabled us to study chromatin interactions in a genome-wide manner at high resolution.

Imbalanced globin chain synthesis determines erythroid cell pathology in thalassemic mice
Background β-thalassemia occurs from the imbalanced globin chain synthesis due to the absence or inadequate β-globin chain production. The excessive unbound α-globin chains precipitate in erythroid precursors and mature red blood cells leading to ...

Reactivation of a developmentally silenced embryonic globin gene
Globin loci harbor genes that are expressed embryonically and silenced postnatally. Here the authors show that zeta-globin silencing depends upon selective hypoacetylation of its TAD subdomain, which blocks its interaction with the alpha-globin super ...

Structural interpretation of the amino acid sequence of a second domain from the Artemia covalent polymer globin [PDF]
Artemia has a complex extracellular hemoglobin of Mr 260,000 comprising two globin chains (Mr 130,000) each of which is a polymer of eight covalently linked domains of Mr 16,000.

Despite frogs avoiding low temperatures, examination of four salamander species revealed that none avoided cold and all possessed cold tolerance. Functional analysis of TRPM8, a cold sensor, showed that all salamander TRPM8s had lost their cold sensitivity.

The role of WDR5 in silencing human fetal globin gene expression
Background Histone H3 lysine 4 (K4) methylation has been linked with transcriptional activity in mammalian cells. The WD40-repeat protein, WDR5, is an essential component of the MLL complex that induces histone H3 K4 methylation, but the role of WDR5 in ...
