Hydroxyurea (hydroxycarbamide) use in adults with haemoglobin SC disease: A real‐world study in Quebec

open access: yesBritish Journal of Haematology, EarlyView.
Summary Haemoglobin SC (HbSC) disease is the second most prevalent form of sickle cell disease, but evidence for hydroxyurea (hydroxycarbamide; HU) to prevent pain episodes was limited until the prospective identification of variables as outcomes for treatment (PIVOT) trial.

Nitric Oxide Reactivity with Globins as Investigated Through Computer Simulation [PDF]

open access: yes, 2008
This chapter reviews the application of classical and quantum-mechanical atomistic simulation tools used in the investigation of several relevant issues in nitric oxide reactivity with globins and presents different simulation strategies based on ...

The DNA binding factor Hmg20b is a repressor of erythroid differentiation

open access: yesHaematologica, 2011
Background In erythroblasts, the CoREST repressor complex is recruited to target promoters by the transcription factor Gfi1b, leading to repression of genes mainly involved in erythroid differentiation.

Methaemoglobinaemia: From pathophysiology to contemporary clinical management

open access: yesBritish Journal of Haematology, EarlyView.
Summary Methaemoglobin (MetHb) is an oxidised form of haemoglobin (Hb) unable to bind oxygen. Raised levels of MetHb reduce the blood's oxygen‐carrying capacity, causing potentially severe hypoxaemia and possible death. The condition arises from three main pathologies: mutations in globin genes causing Haemoglobin‐M, inherited deficiency of the enzyme ...

New biosensors and transgenic mice for multiplex cGMP imaging

open access: yesBritish Journal of Pharmacology, EarlyView.
Background and Purpose Cyclic guanosine monophosphate (cGMP) is a versatile second messenger that is important for human (patho‐)physiology and pharmacotherapy. Live‐cell imaging of cGMP with biosensors allows to elucidate its spatiotemporal dynamics in real time under close‐to‐native conditions. However, to monitor two separate cGMP pools or cGMP/cAMP

Nitrite binding to globins: linkage isomerism, EPR silence and reductive chemistry

open access: yes, 2014
The nitrite adducts of globins can potentially bind via O- or N- linkage to the heme iron. We have used EPR (electron paramagnetic resonance) and DFT (density functional theory) to explore these binding modes to myoglobin and hemoglobin.

Study of invertebrate and plant globins : templates and evolutionary trees

open access: yes, 1992
Globin molecules have a very conservative secondary and tertiary structure, whereas their amino acid sequences are rather variable. To determine the residue restrictions imposed on certain sites of the sequence of non-vertebrate globins (i.e ...

Globins in nonvertebrate species: dispersal by horizontal gene transfer and evolution of the structure-function relationships

open access: yes, 1996
Using a new template based on an alignment of 145 nonvertebrate globins we examined several recently determined sequences of putative globins and globin-like hemeproteins. We propose that all globins have evolved from a family of ancestral, approx.

What influences Hb fetal production in adulthood?

open access: yesRevista Brasileira de Hematologia e Hemoterapia, 2011
Human hemoglobin genes are located in α and β globin gene clusters in chromosomes 16 and 11, respectively. Different types of hemoglobin are synthesized according to the stage of development with fetal hemoglobin (α2γ2) (Hb F) being ...
