Genetics of fetal hemoglobin in Tanzanian and British patients with sickle cell anemia. (ox.ac.uk)
Fetal hemoglobin (HbF, α(2)γ(2)) is a major contributor to the remarkable phenotypic heterogeneity of sickle cell anemia (SCA). (ox.ac.uk)
Clinical trials utilizing hydroxyurea at MTD reported higher fetal hemoglobin (HbF) levels (~20% versus ~15%) compared to those with a fixed lower-dose (Ware, Blood 2010). (ashpublications.org)
The drugs are called HDAC inhibitors, and the investigators have early evidence one called panobinostat can reactivate after birth the gene that produces fetal hemoglobin, which cannot sickle, says Abdullah Kutlar, MD, director of the Center for Blood Disorders at the Medical College of Georgia and Augusta University Health. (news-medical.net)
Histone deacetylases, or HDACs, are enzymes that are among the many ways gene expression gets turned down, a natural process for some genes, like the gamma-globin gene that makes fetal hemoglobin, as we move from childhood to adulthood. (news-medical.net)
Fetal hemoglobin enables a developing baby to capture oxygen from mother's blood while the beta-globin gene produces adult hemoglobin that carries oxygen. (news-medical.net)
Within the first few months after birth, most babies have little to no fetal hemoglobin. (news-medical.net)
That is important for sickle cell because we know in adults that the fetal hemoglobin gene is shut down and we know fetal hemoglobin works very well as a disease modifier. (news-medical.net)
Two HDACs are involved in silencing the fetal hemoglobin gene and panobinostat is a pan-HDAC inhibitor, which means it silences more than one HDAC. (news-medical.net)
Hydroxyurea, the first sickle cell drug approved by the U.S. Food and Drug Administration back in 1998, also increases fetal hemoglobin, although precisely how remains unclear, and it's also used for some cancers. (news-medical.net)
Kutlar notes that if panobinostat continues to show promise, his next steps will include pairing the two fetal hemoglobin promoters to see if there is beneficial synergy. (news-medical.net)
The investigators will be monitoring study participants' levels of the non-sickling fetal hemoglobin as well as levels of F-cells, a subpopulation of red blood cells that contain fetal hemoglobin. (news-medical.net)

Globally, there are more carriers (i.e. healthy people who have inherited only one mutant gene from one parent) of thalassaemia than of sickle-cell anaemia, but the high frequency of the sickle-cell gene in certain areas leads to a high rate of affected newborns. (who.int)
This distribution reflects the fact that sickle-cell trait confers a survival advantage against malaria and that selection pressure due to malaria has resulted in high frequencies of the mutant gene especially in areas of high malarial transmission. (who.int)
For example, in Nigeria, by far the most populous country in the subregion, 24% of the population are carriers of the mutant gene and the prevalence of sickle-cell anaemia is about 20 per 1000 births. (who.int)
The sickle-cell gene has become common in Africa because the sickle-cell trait confers some resistance to falciparum malaria during a critical period of early childhood, favouring survival of the host and subsequent transmission of the abnormal haemoglobin gene. (who.int)
