Special Issue Information

Dear Colleagues,

Anemia affects 1.6 billion people worldwide, about 10% of these individuals are affected by rare anemias of which 80% are hereditary. Hereditary anemias embrace a wide and heterogeneous group of disorders with high clinical and genetic heterogeneity. In recent years, major progress in the understanding of the genetic basis and pathophysiology of hereditary anemias have been achieved. Nevertheless, the pathophysiology of most of the hereditary anemias is poorly understood and, in addition, the responsible gene has not yet been identified for all of them.

This Special Issue on “Molecular Genetics and Pathophysiology of Hereditary Anemias” will include a selection of original papers and reviews focused on genetics and genomics, as well as cellular and molecular mechanisms of red blood cell physiology and pathology. The special issue will focus on hereditary anemias, in particular red blood cell membrane structural defects, red blood cell membrane transport defects, defects of erythropoiesis, enzyme defects, anemias related to iron metabolism defects; diagnostic approaches, epigenetics, functional genomics, genome editing, generation of cellular and animal models for red blood cell diseases, gene expression profiling of erythroid cells, and description of new pathophysiologic mechanisms.

Orphan nuclear receptor estrogen-related receptor γ (ERRγ) is an important transcription factor modulating gene transcription involved in endocrine control of liver metabolism. Transferrin receptor 2 (TFR2), a carrier protein for transferrin, is involved in hepatic iron overload in alcoholic liver disease (ALD). However, TFR2 gene transcriptional regulation in hepatocytes remains largely unknown. In this study, we described a detailed molecular mechanism of hepatic TFR2 gene expression involving ERRγ in response to an endocannabinoid 2-arachidonoylglycerol (2-AG). Treatment with 2-AG and arachidonyl-2′-chloroethylamide, a selective cannabinoid receptor type 1 (CB1) receptor agonist, increased ERRγ and TFR2 expression in hepatocytes. Overexpression of ERRγ was sufficient to induce TFR2 expression in both human and mouse hepatocytes. In addition, ERRγ knockdown significantly decreased 2-AG or alcohol-mediated TFR2 gene expression in cultured hepatocytes and mouse livers. Finally, deletion and mutation analysis of the TFR2 gene promoter demonstrated that ERRγ directly modulated TFR2 gene transcription via binding to an ERR-response element. This was further confirmed by chromatin immunoprecipitation assay. Taken together, these results reveal a previously unrecognized role of ERRγ in the transcriptional regulation of TFR2 gene expression in response to alcohol. Full article

Thalassemia, a chronic disease with chronic anemia, is caused by mutations in the β-globin gene, leading to reduced levels or complete deficiency of β-globin chain synthesis. Patients with β-thalassemia display variable clinical severity which ranges from asymptomatic features to severe transfusion-dependent anemia and complications in multiple organs. They not only are at increased risk of blood-borne infections resulting from multiple transfusions, but they also show enhanced susceptibility to infections as a consequence of coexistent immune deficiency. Enhanced susceptibility to infections in β-thalassemia patients is associated with the interplay of several complex biological processes. β-thalassemia-related abnormalities of the innate immune system include decreased levels of complement, properdin, and lysozyme, reduced absorption and phagocytic ability of polymorphonuclear neutrophils, disturbed chemotaxis, and altered intracellular metabolism processes. According to available literature data, immunological abnormalities observed in patients with thalassemia can be caused by both the disease itself as well as therapies. The most important factors promoting such alterations involve iron overload, phenotypical and functional abnormalities of immune system cells resulting from chronic inflammation oxidative stress, multiple blood transfusion, iron chelation therapy, and splenectomy. Unravelling the mechanisms underlying immune deficiency in β-thalassemia patients may enable the designing of appropriate therapies for this group of patients. Full article
