Involved in oxygen transport from the lung to the various peripheral tissues Hemopressin acts as an antagonist peptide of the cannabinoid receptor CNR1 (PubMed:18077343). Hemopressin-binding efficiently blocks cannabinoid receptor CNR1 and subsequent signaling (PubMed:18077343)
Heinz body anemias
Form of non-spherocytic hemolytic anemia of Dacie type 1. After splenectomy, which has little benefit, basophilic inclusions called Heinz bodies are demonstrable in the erythrocytes. Before splenectomy, diffuse or punctate basophilia may be evident. Most of these cases are probably instances of hemoglobinopathy. The hemoglobin demonstrates heat lability. Heinz bodies are observed also with the Ivemark syndrome (asplenia with cardiovascular anomalies) and with glutathione peroxidase deficiency.

Molecular Methods for Rare Hemoglobinopathy Cases: First Brazilian Report of Pediatric Siblings with Hb O-Arab and Alpha-Thalassemia.
Hemoglobinopathies are prevalent globally; diagnosis is complex in high genetic admixture populations like Brazil. We report, in two pediatric siblings, the first documented cases in Brazil of heterozygosity for hemoglobin (Hb) O-Arab with coinheritance of α-thalassemia (αα/-α4.2; -α3.7/-α4.2), resulting in microcytic and hypochromic anemia. Electrophoresis, high-performance liquid chromatography, HBB gene sequencing, and multiplex-polymerase chain reaction confirmed these complex genotypes. Although rare, Hb O-Arab significantly impacts clinical status, particularly in patients with coexisting hemoglobinopathies, such as α-thalassemia and Hb S, the latter resulting in a sickle cell disease form. This highlights the crucial role of molecular diagnostics, early screening, and genetic counseling in the accurate management and prevention of misdiagnosis in hemoglobinopathies.
Local heterochromatin enrichment promotes telomere clustering and PML nuclear body assembly at telomeres.
The alternative lengthening of telomeres (ALT) pathway is a recombination-based telomere maintenance mechanism used by a subset of human cancers and is characterized by telomere clustering within telomere-associated promyelocytic leukemia (PML) nuclear bodies (APBs). Although ALT telomeres exhibit reduced nucleosome density, they are paradoxically enriched for heterochromatin-associated factors, raising questions about how chromatin state contributes to ALT. Here, we use a targeted system to locally modulate heterochromatin features at telomeres. We show that telomeric heterochromatin promotes telomere clustering and multiple hallmarks of APB-associated telomere processing in ALT-positive (ALT+) cells. Remarkably, molecular tethering of HP1α at telomeres is sufficient to nucleate PML nuclear bodies in non-ALT cells and, in specific contexts, induce biomarkers of ALT-like recombination. We further demonstrate that heterochromatin-driven PML-telomere colocalization is inhibited by α-thalassemia/mental retardation, X-linked and death domain-associated protein (ATRX/DAXX), factors frequently mutated in ALT+ tumors. Together, these findings establish telomeric heterochromatin as a driver of telomere clustering and PML nuclear body assembly, shaping ALT-associated subnuclear compartmentalization.
ATRX loss couples genome instability at a G-rich repeat to dysregulation of human alpha-globin expression.
Germline mutations in the chromatin remodelling protein ATRX cause a severe developmental disorder associated with α-thalassemia. In addition, ATRX is amongst the twenty genes most frequently mutated in cancer. How ATRX mutations alter gene expression remains unclear. Using the α-globin locus as a model, here we show that ATRX deficiency downregulates α-globin in a subset of cells exhibiting DNA damage. A G-rich repeat at the α-globin locus serves as a potential site of G-quadruplex formation and DNA damage. ATRX binds this repeat co-transcriptionally, and its loss increases R-loop accumulation at this site, leading to local DNA damage and transcriptional disruption in cis. Deletion of this repeat abolishes this effect, while targeted DNA damage reinstates it. These findings reveal a mechanism linking ATRX's role in genome stability to transcriptional regulation and uncover a molecular basis of human genetic disease mediated via a distal G-rich repeat.
Prevalence of Severe Thalassemia and Performance of Prenatal Screening Tests Among Pregnant Women at Siriraj Thalassemia Center in Thailand.
Severe thalassemia remains a significant public health concern in Southeast Asia. Prenatal screening is an effective strategy for early detection and prevention. This study aimed to determine the prevalence of severe thalassemia and assess the performance of prenatal screening at the Siriraj Thalassemia Center, Siriraj Hospital, Thailand. A retrospective review was conducted using data from January 2018 to December 2023. A total of 18,976 pregnant women underwent initial screening with mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), and hemoglobin (Hb) typing. Of these, 12,499 tested positive. Complete screening data from 6,698 male partners identified 18.3% of couples as high-risk. Deoxyribonucleic acid (DNA) analysis and prenatal diagnostic testing were performed for at-risk pregnancies. Among high-risk couples, 75.2% of fetuses were identified by DNA analysis as being at risk for severe thalassemia, and 34.2% were confirmed as affected. The distribution of severe thalassemia types included Hb Bart's Hydrops Fetalis (15.8%), homozygous β-thalassemia (1.6%), and β-thalassemia/Hb E disease (16.8%). The most frequent α-thalassemia genotype in Hb Bart's cases was homozygous α0-thalassemia (--SEA/--SEA; 96.3%). The most common β-thalassemia mutation was a 4-base pair deletion at codons 41/42 (-TTCT; 40.2%). DNA testing for α-thalassemia showed 100% specificity and positive predictive value (PPV). For β-thalassemia, the sensitivity, specificity, PPV, and negative predictive value (NPV) were 97.6%, 98.9%, 96.1%, and 99.3%, respectively. The findings underscore the effectiveness of prenatal screening and diagnosis in identifying severe thalassemia, highlighting their importance for informing prevention strategies and guiding public health planning in high-prevalence settings.
