MN•CS•IO System: Cross‐Species Study for HBB Function in High‐Altitude Hypoxia Adaptation

Advanced Science, EarlyView.
We developed an integrative mesh‐nanorod sorting, chitosan nanoparticle delivery, and intraosseous injection (MN•CS•IO) system to investigate HBB in high‐altitude hypoxia adaptation. Transplanting Tibetan animals' HBB‐modified Lin‐ cells into mice achieved 95.59% transfection efficiency and 8.15% HBB expression. High‐altitude HBB recipients upregulated

Genetic variants in the G gamma-globin promoter modulate fetal hemoglobin expression in the Colombian population [PDF]

Genetics and Molecular Biology, 2020
Fetal hemoglobin (HbF) is a determining factor for the development of sickle cell anemia. High HbF levels lower the intensity of symptoms of this disease. HbF levels can vary in patients with sickle cell anemia and individuals without the disease.

HOPE Kids 2: Phase 3, Randomized Trial of Voxelotor in Children With SCD and Conditional Cerebral Blood Flow Velocities

American Journal of Hematology, EarlyView.
ABSTRACT Children with SCD have elevated stroke risk, correlated with cerebral blood flow velocity (CBFV). HOPE Kids 2 was a phase 3, multicenter, double‐blind, placebo‐controlled trial evaluating the effect of voxelotor on CBFV. Participants aged 2 to < 15 years with SCD (HbSS/HbSβ0) and conditional CBFV (170 to < 200 cm/s) were randomized 1:1 to ...

The Presence and Percentage of Circulating Nucleated Red Blood Cells Reveal Distinct Characteristics in Adults With Sickle Cell Disease

American Journal of Hematology, EarlyView.
ABSTRACT Although circulating nucleated red blood cells (cNRBCs) have previously been detected in patients with sickle cell disease (SCD), their prevalence and clinical significance during steady‐state disease have not been established. We retrospectively analyzed 270 adults with an SS or Sβ0‐thalassemia genotype.

Haptoglobin gene polymorphisms and interleukin-6 and -8 levels in patients with sickle cell anemia

Revista Brasileira de Hematologia e Hemoterapia, 2015
BACKGROUND: Haptoglobin genotypes, and interleukin-6 and -8 participate in the pathophysiology of sickle cell anemia. The expression of cytokines is regulated by genetic mechanisms however the effect of haptoglobin polymorphisms on these cytokines is not

Hematological and hemorheological determinants of the six-minute walk test performance in children with sickle cell anemia. [PDF]

PLoS ONE, 2013
The six-minute walk test is a well-established submaximal exercise reflecting the functional status and the clinical severity of sickle cell patients. The aim of the present cross-sectional study was to investigate the biological determinants of the six ...

ANK1 and EPB41 Variants and The Risk of Glucocorticoid‐Induced Osteonecrosis

Arthritis &Rheumatology, EarlyView.
Objective Steroid‐induced osteonecrosis of the femoral head (SONFH) is a refractory skeletal disorder influenced by genetic and environmental factors. However, conclusive pathogenic genetic evidence remains elusive due to the limited exploration of rare damaging variants. In this study, we aimed to identify rare variants associated with SONFH.
