Sickle cell disease is an extremely debilitating condition that affects up to 40% of the population in African countries, with patients suffering episodes of excruciating pain, organ damage and reduced life-expectancy. (eurekalert.org)
This disease is caused by a mutation in a gene that makes haemoglobin, the protein that carries oxygen in red blood cells, with the damaged haemoglobin distorting the shape of red blood cells, causing painful and potentially life-threatening blockages in blood vessels. (eurekalert.org)
In their current Disease Models & Mechanisms article , Mitchell Weiss and colleagues from St. Jude Children's Research Hospital, Memphis, USA, investigated a promising new treatment that is being developed in Weiss' lab and works by editing genes to switch on the production of this healthy, foetal haemoglobin in adult red blood cells. (eurekalert.org)
When testing the treatment in mice, the researchers found that even though the lab mice had the symptoms of sickle cell disease, the foetal haemoglobin gene and surrounding DNA were not properly configured, making the revolutionary stem-cell treatment ineffective or even harmful in the animals and raising concerns for future research testing new gene-based therapies in these laboratory mice. (eurekalert.org)
Before a new treatment can be tested on people, scientists test them on laboratory animals, so Weiss and colleagues tried their new gene therapy in two types of mice that carry the symptoms of sickle cell disease: so-called 'Berkeley' and 'Townes' mice. (eurekalert.org)
However, the levels of foetal haemoglobin produced in the red blood cells of Townes mice were 7- to 10-times lower than seen when this approach is used in human cells grown in the laboratory and not high enough to reduce clinical signs of sickle cell disease. (eurekalert.org)
Weiss and colleagues then wanted to find out why this new treatment was not successful in the Berkeley mice, which have been used for decades to test treatments for sickle cell disease. (eurekalert.org)
Therefore, the team sequenced the haemoglobin genes and surrounding DNA of the Berkeley mice and discovered that instead of having a single copy of the mutated human gene, the mice had 22 randomly arranged, broken-up copies of the mutated human sickle cell disease gene and 27 copies of the human foetal haemoglobin that the team had hoped to activate to cure the mice of the disease. (eurekalert.org)
Dr Weiss commented, "Our findings will help scientists using the Berkeley and Townes mice decide which to use to address their specific research question relating to sickle cell disease or haemoglobin. (eurekalert.org)

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)
Sickle-cell anaemia is particularly common among people whose ancestors come from sub-Saharan Africa, India, Saudi Arabia and Mediterranean countries. (who.int)
Frequencies of the carrier state determine the prevalence of sickle-cell anaemia at birth. (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)
This means that in Nigeria alone, about 150 000 children are born annually with sickle-cell anaemia. (who.int)
The public health implications of sickle-cell anaemia are significant. (who.int)
When health impact is measured by under-five mortality, sickle-cell anaemia contributes the equivalent of 5% of under- five deaths on the African continent, more than 9% of such deaths in west Africa, and up to 16% of under-five deaths in individual west African countries. (who.int)
Sickle-cell anaemia covers a wide spectrum of illness. (who.int)
Most affected people have chronic anaemia with a haemoglobin concentration of around 8 g/dl. (who.int)
If you inherit the sickle cell gene from both parents then you will have sickle cell anaemia, which causes serious health problems. (labtestsonline.org.uk)
Sickle cell anaemia during pregnancy is dangerous as it can impact the flow of blood to the baby and result in his slow growth and development. (firstcry.com)
Sickle-cell anaemia (SCA) was first rec- aggregability, elevated beta thromboglobu- ognized as a haematological disorder more lin, reduced levels of protein C (PC) and than 90 years ago [1]. (who.int)
The sickle-cell anaemia group lower showed Z-scores for weight (p = 0.0002), height (p= 0.0184) and body mass index (p = 0.0011) than the control group at Te1. (bvsalud.org)
0.0001) were lower in the sickle-cell anaemia group. (bvsalud.org)
Men showed greater weight commitment than women at the three study times (Te1: p= 0.0340, Te2: p= 0.0426 and Te3: p= 0.0387) and lower body mass index in Te3 (p= 0.0155) in the sickle-cell anaemia group. (bvsalud.org)
There was a significant increase in weight when comparing Te1 with Te3 (p= 0.0009) and in height when comparing Te1 with Te2 (p= 0.0292) and with Te3 (p= 0.0003) in the sickle-cell anaemia group. (bvsalud.org)
Age at menarche was delayed and lower in the sickle-cell anaemia group (mean = 15 years). (bvsalud.org)
At Te1, TSH levels were higher (p= 0.0080) and T3 levels were lower (p= 0.0020) in the sickle-cell anaemia group. (bvsalud.org)
Women with sickle-cell anaemia showed no fertility problems. (bvsalud.org)
The findings highlight the need to investigate the intention of paternity and fertility among men with sickle-cell anaemia. (bvsalud.org)

Hemoglobin is a protein in red blood cells that carries oxygen to the body. (chkd.org)

Methemoglobin occurs when methemoglobin comprises more than 1% of the hemoglobin [Flomenbaum et al. (cdc.gov)

Red blood cells contain hemoglobin, a protein that carries oxygen. (cdc.gov)
Healthy red blood cells are round, and they move through small blood vessels to carry oxygen to all parts of the body. (cdc.gov)
SCD can cause severe complications, which appear when the sickle cells block vessels in different areas of the body. (healthline.com)
Sickle cells are easily broken. (healthline.com)
Sickle cells live for a maximum of 10 to 20 days. (healthline.com)
Splenic sequestration is a blockage of the splenic vessels by sickle cells. (healthline.com)
Iron does more than help red blood cells carry oxygen. (psychcentral.com)
Reduced hemoglobin means your red blood cells can't carry enough oxygen. (psychcentral.com)
Anemias are conditions that lead to low levels of hemoglobin or red blood cells in the body. (medicalnewstoday.com)
This involves the body producing too few healthy red blood cells to carry enough oxygen around the body. (medicalnewstoday.com)
The main problems arise from the tendency of the red blood cells to become sickle-shaped and block capillaries at low oxygen tension. (who.int)
They form into the shape of a sickle, or the letter "C." These sickle cells tend to clump together and can't easily move through the blood vessels. (chkd.org)
In pregnancy, it's important for blood cells to be able to carry oxygen. (chkd.org)
Some women may need blood transfusions to replace the sickle cells with fresh blood. (chkd.org)
Blood transfusions can help the blood carry oxygen and lower the number of sickle cells. (chkd.org)
It measures your hemoglobin, the part of your red blood cells that carries oxygen. (akronchildrens.org)
In those with SCD, the shape and rigidness of affected hemoglobin make red blood cells less flexible. (medicalnewstoday.com)
The sickle-shaped cells tend to clog small blood vessels and block blood flow to the tissues and organs. (childrensnational.org)
The new medicine, Casgevy, works by targeting the problematic gene in a patient's bone marrow stem cells so that the body can make properly functioning hemoglobin. (wave3.com)
This mutation leads to impaired oxygen transport, causing red blood cells to adopt a sickle shape. (pharmamanufacturing.com)
Hemoglobinopathies affect the red blood cells' ability to carry oxygen from the lungs to other parts of the body. (ms.gov)
The pigmentary changes are believed to be secondary to the liberation of free iron as a result of hemolysis of red blood cells that contain the affected hemoglobin. (medscape.com)
Vasoocclusion also is in part due to the interaction between sickled cells and the vascular endothelium. (medscape.com)
The adherence of sickled cells to the endothelium triggers an inflammatory process with the release of inflammatory agents. (medscape.com)
The activated endothelia are procoagulant, thereby inducing further adherence of sickled cells to the endothelium. (medscape.com)
In such a trial, clinicians would draw participants' blood, separate out their stem cells and then use a gene-editing tool called CRISPR to fix the sickle cell defect. (stanford.edu)
First, they removed stem cells - cells in the bone marrow programmed to become red blood cells - from the mice and used gene editing to modify part of the stem cells' DNA to switch on the healthy foetal haemoglobin gene. (eurekalert.org)
Surprisingly, 70% of the Berkeley mice died from the therapy and it only activated production of the healing foetal haemoglobin gene in 3.1% of mouse's stem cells. (eurekalert.org)
In contrast, the experimental treatment activated the foetal haemoglobin gene in 57% of red blood cells in the Townes mice and did not affect the animals' survival. (eurekalert.org)
Pain can occur when the misshapen red sickle cells obstruct the blood vessels, causing bone pains, commonly in the legs, back, arms, and chest. (medstarhealth.org)
In SCD, the bone marrow produces red blood cells containing defective sickle hemoglobin. (medstarhealth.org)
It happens when hemoglobin - a protein found in blood cells - becomes defective, affecting the integrity of red blood cells. (medicalert.org)
Sickle cells also have a significantly shorter lifespan than regular red blood cells. (medicalert.org)
Why Do Cells Become Sickle-Shaped? (kidshealth.org)
Hemoglobin (pronounced: HEE-muh-glow-bin) is the part of the red blood cells that carries oxygen. (kidshealth.org)
Sickle-shaped cells break down faster than normal red blood cells. (kidshealth.org)
Others prevent cells from clumping together or breaking down so they can carry oxygen more easily. (kidshealth.org)
The red blood cells carry hemoglobin, which is the protein whose job it is to carry oxygen from the lungs to the blood, to the tissues in the body. (contemporaryobgyn.net)
These sickled cells then don't move very well through the small blood vessels and as a result will cause blockages. (contemporaryobgyn.net)
Sickle cells are less flexible than normal RBCs, which inhibits them from efficiently moving inside the blood vessels. (dignityhealth.org)
Hemoglobin is found in red blood cells and it gives blood its color. (cdc.gov)
In SCD, the red blood cells become hard and sticky and look like a C-shaped farm tool called a "sickle. (cdc.gov)
Those microscopic sickle-shaped cells clumped together, unleashing a cascade of damage. (investorvillage.com)
Red blood cells contain hemoglobin, a protein that enables them to carry oxygen from the lungs and deliver it to all parts. (msdmanuals.com)
The sickle-shaped cells become more numerous when people have infections or low levels of oxygen in the blood. (msdmanuals.com)
The sickle cells are fragile and break apart easily. (msdmanuals.com)
Because the sickle cells are stiff, they have difficulty traveling through the smallest blood vessels (capillaries), blocking blood flow and reducing oxygen supply to tissues in areas where capillaries are blocked. (msdmanuals.com)
People with this condition have sickle-shaped red blood cells. (firstcry.com)
While normal blood cells are shaped like an "O" and are round, smooth and flexible, abnormal ones are shaped more like a "C" or a sickle and are known to clump together, blocking the flow of oxygen through the blood and causing tissue damage and a lot of pain. (firstcry.com)

Written and edited by experts in the field, this collection from Cold Spring Harbor Perspectives in Biology covers all aspects of hemoglobin and its diseases. (cshlpress.com)
There are over 600 hemoglobin diseases that have been medically defined by the American College of Medical Genetics. (ms.gov)
Together, this group of diseases where two abnormal traits are inherited is referred to as the sickle cell diseases (SCD). (medstarhealth.org)
The hope," said Valentine, "is that if the feds and governments and society can figure this out with sickle cell, they can figure this out with other diseases. (investorvillage.com)
Haemoglobin SD, SE, and SO are other types of sickle cell diseases that are rare and do not usually result in any severe symptoms. (firstcry.com)
