ACTIVIN RECEPTOR LIGAND FOR THR TREATMENT OF BETA-THALASSEMIA: a SERENDIPITOUS DISCOVERY

Mediterranean Journal of Hematology and Infectious Diseases, 2020
b-thalassemia is a hereditary disorder caused by defective production of b-globin chains of hemoglobin (Hb) that leads to an increased a/b globins ratio with subsequent free a-globins.

The diversity of globin‐coupled sensors [PDF]

FEBS Letters, 2003
The recently discovered globin‐coupled sensors (GCSs) are heme‐containing two‐domain transducers distinct from the PAS domain superfamily. We have identified an additional 22 GCSs with varying multi‐domain C‐terminal transmitters through a search of the complete and incomplete microbial genome datasets.

Decreased cold‐sensing function of the transient receptor potential channel TRPM8 from tailed amphibians

FEBS Open Bio, EarlyView.
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.

Nitrophorins and nitrobindins: structure and function

Biomolecular Concepts, 2017
Classical all α-helical globins are present in all living organisms and are ordered in three lineages: (i) flavohemoglobins and single domain globins, (ii) protoglobins and globin coupled sensors and (iii) truncated hemoglobins, displaying the 3/3 or the

Dose‐Dependent Reprogramming of Chromatin Accessibility by SOX4 Drives the Transcriptional Response to Iron Overload

Advanced Science, EarlyView.
This study demonstrates that iron overload triggers widespread chromatin compaction and transcriptional repression in human granulosa cells, recapitulating features of endometriosis. The epigenetic reprogramming is orchestrated by a TFEB‐SOX4‐SWI/SNF axis, with SOX4 acting as a central, dosage‐sensitive regulator.

Testes-specific hemoglobins in Drosophila evolved by a combination of sub- and neofunctionalization after gene duplication

BMC Evolutionary Biology, 2012
Background For a long time the presence of respiratory proteins in most insects has been considered unnecessary. However, in recent years it has become evident that globins belong to the standard repertoire of the insect genome.

Engineering neuroglobin nitrite reductase activity based on myoglobin models

Biochemistry and Biophysics Reports, 2023
Neuroglobin is a hemoprotein expressed in several nervous system cell lineages with yet unknown physiological functions. Neuroglobin presents a very similar structure to that of the related globins hemoglobin and myoglobin, but shows an hexacoordinate ...

Enhanced Intracellular Stability and Translation Efficiency of mRNA Drugs by a 2‐arm mRNA Platform

Advanced Science, EarlyView.
We constructed a 2‐arm mRNA, characterized by a unique topology formed through the dimerization of two mRNA 3’ tails. The 2‐arm mRNA improves 3’ tail stability and resistance to nuclease degradation, resulting in an intracellular half‐life of up to 65 h. This method substantially enhances the translation capacity of mRNA drugs.

Biophysical characterisation of neuroglobin of the icefish, a natural knockout for hemoglobin and myoglobin. Comparison with human neuroglobin. [PDF]

PLoS ONE, 2012
The Antarctic icefish Chaenocephalus aceratus lacks the globins common to most vertebrates, hemoglobin and myoglobin, but has retained neuroglobin in the brain. This conserved globin has been cloned, over-expressed and purified. To highlight similarities

Correction of Ineffective Erythropoiesis and Normalization of Iron Homeostasis After Exagamglogene Autotemcel in Transfusion‐Dependent β‐Thalassemia

American Journal of Hematology, EarlyView.
ABSTRACT Exagamglogene autotemcel (exa‐cel) is a one‐time, ex vivo, CRISPR‐Cas9 gene edited cell therapy approved for patients with transfusion dependent β‐thalassemia (TDT) aged 12–35 years. In a Phase 3 study (CLIMB THAL‐111), exa‐cel treatment resulted in reactivation of fetal hemoglobin and increases in total hemoglobin, leading to transfusion ...
