Summary: The study demonstrated that acyclovir induces the expression of the gamma-globin gene and HbF synthesis, without affecting terminal erythroid differentiation and proliferation. It also downregulated gamma-globin repressors BCL11A and SOX6, while upregulating the master erythroid transcription factor GATA-1, suggesting its potential as an effective HbF inducer for treating beta-globin disorders.

Summary: Sickle cell disease (SCD) is caused by beta-globin gene mutations. G9a inhibitors, including RK-701, have been proposed as therapeutic agents for inducing fetal globin expression. This study describes the development of RK-701 as a selective and non-genotoxic G9a inhibitor, which upregulates BGLT3 long non-coding RNA and induces gamma-globin expression. BGLT3 is identified as an essential factor for gamma-globin induction and its universal role suggests its importance in SCD treatment.

Summary: This article examines the pathophysiology of beta hemoglobinopathies, the physiology of HbF, intracellular distribution, and the regulation of HbF expression. Inducing high levels of HbF by targeting its regulatory pathways pharmacologically or with cell-based therapeutics provides major clinical benefit and perhaps a 'cure.'

Summary: This study proposes a novel Cas9/AAV6-mediated genome editing strategy for treating beta-thalassemia. By introducing naturally occurring HPFH mutations and disrupting BCL11A binding sites in HBG1/HBG2 promoters, precise on-target editing and significantly increased gamma-globin expression were observed.

Summary: Hydroxyurea is commonly used for the treatment of sickle cell anemia (SCA), but there is variability in patient response. This systematic review explores the impact of genetic polymorphisms on HbF levels in SCA patients treated with hydroxyurea, and identifies SNPs and genes associated with HbF changes. The findings suggest that changes in HbF levels upon hydroxyurea therapy are likely regulated by multiple loci.

Summary: Beta-hemoglobinopathies, including sickle cell disease and beta-thalassemia, are genetic disorders characterized by mutations in the HBB gene. Current treatments involve pharmacological agents to raise levels of fetal hemoglobin, but gene editing technologies like CRISPR/Cas9 offer potential permanent effects. This meta-analysis compared two gene editing targets, BCL11A and HBG1/2, and found that HBG1/2 significantly increased HbF expression compared to BCL11A.

Summary: This study analyzed Cinchona alkaloids as natural HbF-inducing agents in human erythroid cells, and found that cinchonidine and quinidine are potent inducers of gamma-globin mRNA and HbF in erythroid progenitor cells isolated from beta-thalassemia patients. These compounds may be considered for the development of pre-clinical approaches for therapeutic protocols of beta-thalassemia.

Summary: The use of LSD1 inhibitor RN-1 significantly increases gamma-globin transcript and HbF expression levels in erythroid cells derived from beta(0)-thalassemia/HbE patients, without affecting cell viability and proliferation at low concentration, but leading to decreased cell numbers at high concentration.

Summary: Influenza B virus significantly contributes to global morbidity, mortality, and economic loss related to influenza. Current gold standard serological assays for influenza B have operational issues with sensitivity and specific antigen requirement. This study compared gold standard assays with a newer Pseudotype-based Microneutralisation assay, finding strong correlations for strains in the Yamagata lineage but not in the Victoria lineage.

Summary: This study demonstrates that forced enhancer rewiring can alter gene expression and presents a potential strategy for therapeutic purposes. By transducing hematopoietic stem and progenitor cells (HSPCs) with lentiviral vectors expressing a synthetic transcription factor (ZF-Ldb1) and forcing contact between the enhancer and the target gene, elevated expression of the target gene was achieved in adult-type erythroid cells. This proof of concept was demonstrated in both mice and rhesus macaque models.

Summary: Lentiviral vector (LV)-based gene therapy shows promise in treating various diseases. By analyzing patient samples, we found LV integrome signatures related to genomics, epigenomics, and the 3D structure of the genome. These signatures were validated in cellular therapies and differences in 3D genome signatures between LV and gamma retrovirus integromes were identified, potentially explaining the lower risk of mutations in LV-based gene therapy.
