The feed utilisation of young chicks is characterised by a suboptimal fat digestibility, which can be improved by means of dietary emulsifiers. The objective of this study was to evaluate the effect of dietary Globin on the energy efficiency and ...

Expression of heterologous proteins in adult mammalian neurons is a valuable technique for the study of neuronal function. The postmitotic nature of mature neurons prevents effective DNA transfection using simple, cationic lipid-based methods.

The strong enhancer element in the immediate early region of the human cytomegalovirus genome [PDF]
The human cytomegalovirus (HCMV), a member of the herpesvirus group, was found to possess a strong transcription enhancer in the immediate early gene region. Co-transfection of enhancerless SV40 DNA with randomly fragmented HCMV DNA yielded two SV40-

Gelling Properties of Globin-Succinylated Globin Conjugates.
2種類のグロビン-サクシニル化グロビン複合体(CMHTとCUT)を調製し,各複合体のゲル特性について検討した.(1) CMHTはGの配合比率が高くなる程ゲル形成pHは中性の方へ拡大した.例えば, GとSGの配合率が3:7の場合,ゲル形成pHは2.0であったが,G:SG=9:1の場合,ゲルはpH 2.0~3.5の範囲で形成された.一方, G:SGの配合比率が7:3と9:1のCUTの場合,ゲル形成pHは極めて狭い範囲に限定された.(2) ゲルの透明度はCMHT, CUTともにより酸性側で高く,また,グロビンの配合比率が高くなる程透明度も高くなる傾向を示した.(3) 複合体ゲルのゲル強度を測定した. CMHTの場合, G:SG=5:5 (pH 2.0)で高いゲル強度が得られた.

Primitive and definitive erythropoiesis in mammals
Red blood cells (RBCs), which constitute the most abundant cell type in the body, come in two distinct flavors- primitive and definitive. Definitive RBCs in mammals circulate as smaller, anucleate cells during fetal and postnatal life, while primitive ...

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-

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 ...

A Very Strong Enhancer Is Located Upstream of an Immediate Early Gene of Human Cytomegalovirus [PDF]
A strong transcription enhancer was identified in the genomic DNA (235 kb) of human cytomegalovirus (HCMV), a ubiquitous and severe pathogen of the herpesvirus group.

Physiological and Aberrant γ-Globin Transcription During Development
The expression of the fetal Gγ- and Aγ-globin genes in normal development is confined to the fetal period, where two γ-globin chains assemble with two α-globin chains to form α2γ2 tetramers (HbF). HbF sustains oxygen delivery to tissues until birth, when

Revealing mammalian evolutionary relationships by comparative analysis of gene clusters [PDF]
Many software tools for comparative analysis of genomic sequence data have been released in recent decades. Despite this, it remains challenging to determine evolutionary relationships in gene clusters due to their complex histories involving ...
